How Docker Works & Architecture?

Docker works by creating a lightweight, isolated environment for running applications. This environment is called a container. A container is a package of software that includes everything that an application needs to run, such as the application’s code, runtime, system tools, system libraries, and settings. Docker uses a client-server architecture. The Docker client is a program that you use to interact with the Docker daemon. The Docker daemon is a program that runs on the host machine and manages the containers.

When you use Docker to run an application, the Docker client sends a request to the Docker daemon. The Docker daemon then creates a container from the specified image and starts the application in the container. The Docker client can then interact with the application through the Docker API. The Docker architecture is designed to be efficient and scalable. Containers are lightweight and isolated, so they can be easily created and destroyed. This makes it easy to scale your applications up or down as needed.

Here are some of the benefits of using Docker:

• Portability: Docker containers are portable, so you can deploy your applications to any machine that has Docker installed. This makes it easy to deploy your applications to production or to test your applications on different environments.
• Scalability: Docker containers are scalable, so you can easily add or remove containers as needed. This makes it easy to scale your applications up or down as your traffic increases or decreases.
• Reusability: Docker images can be reused, so you can save time and effort when building new applications. This is especially beneficial for large applications with a lot of shared code.
• Security: Docker containers are isolated, so they are more secure than traditional ways of deploying applications. This is because Docker containers do not share the underlying operating system with other applications.
• Efficiency: Docker containers are efficient, so they can help you save money on your cloud computing costs. This is because Docker containers only use the resources that they need, and they do not need to install all of the software that is needed to run your application.

How Android Works & Architecture?

Android is an open-source operating system designed primarily for touchscreen mobile devices such as smartphones and tablets. It provides a platform for developers to create and run various applications. But how does it all come together? Let’s find out.

The Linux Kernel: The Backbone

At the heart of Android lies the Linux kernel, which serves as the foundation for the operating system. The kernel handles essential tasks such as memory management, process management, and device drivers. It acts as an intermediary between the hardware and the higher-level software layers.

The Android Runtime (ART)

On top of the Linux kernel, we have the Android Runtime (ART). ART is responsible for executing and managing applications written in the Java programming language. It utilizes a just-in-time (JIT) compilation technique to improve the performance of the applications. ART also provides a managed environment for memory allocation and garbage collection.

The Native C/C++ Libraries

Android includes a set of native libraries written in C/C++. These libraries provide essential functionalities such as graphics rendering, audio processing, and network communication. They allow developers to create high-performance applications that can leverage the power of the underlying hardware.

The Application Framework

The Application Framework layer provides a set of APIs (Application Programming Interfaces) that allow developers to build applications on top of the Android platform. It includes components such as Activity Manager, Content Providers, and Resource Manager. These components enable developers to create interactive and rich applications.

The System Apps

Android comes preloaded with a set of system apps that provide core functionalities such as a phone dialer, contacts, messaging, and browser. These apps are an integral part of the Android experience and are essential for the day-to-day usage of the device.

The User Apps

Apart from the system apps, users can install their own applications from the Google Play Store or other sources. These user apps can range from games and social media apps to productivity tools and utility apps. The possibilities are endless, and users have the freedom to customize their Android experience.

The User Interface

Finally, we have the User Interface (UI) layer, which is what users interact with. Android provides a flexible and customizable UI framework that allows developers to create visually appealing and user-friendly interfaces. From the lock screen to the home screen and the app interfaces, the UI layer plays a crucial role in the overall user experience.

How to Install and Configure Android?

Sure, here are the steps on how to install and configure Android:

• Download Android Studio. You can download Android Studio from the Android Developers website: https://developer.android.com/studio/install.
• Run the installer. Once the installer is downloaded, run it and follow the on-screen instructions.
• Install the SDK. Android Studio will automatically install the SDK when you run the installer.
• Configure Android Studio. Once the SDK is installed, you need to configure Android Studio. This includes setting the SDK location, choosing a theme, and accepting the license agreements.
• Create a new project. Once Android Studio is configured, you can create a new project. This will create a new Android app.

In 1997, a programmer named Kent Beck created a development environment plugin, JUnit, to test small pieces of code. Developers wrote test code that assessed the source code. He called the approach unit testing.

A unit test is a way of testing a unit – the smallest piece of code that can be logically separated into a system. In most programming languages, this is a function, a subroutine, a method, or a property. The separate part of the definition is important. In his book “Working Effectively with Legacy Code”, author Michael Feathers states that such tests are not unit tests when they rely on external systems: “If it talks to a database, it can run across the network.” If it touches the file system, it requires system configuration, or it cannot be run at the same time as any other test.”

What is Unit Testing?

Unit testing is a software testing technique through which individual units of software i.e. groups of computer program modules, usage procedures, and operating procedures are tested to determine whether they are suitable for use or not. It is a testing method using which each independent module is tested to determine if there is a problem by the developer himself. This is correlated with the functional correctness of the independent modules.

Unit testing is defined as a type of software testing where individual components of the software are tested. Unit testing of software products is done during the development of an application. An individual component can be either an individual act or a process. Unit testing is usually done by the developer.

Features of Unit Testing are:

• Makes the Process Agile
• Quality of Code
• Finds Software Bugs Early
• Facilitates Changes and Simplifies Integration
• Provides Documentation
• Debugging Process
• Design
• Reduce Costs

Unit Testing Interview Questions and Answers

1. What Is Unit Testing?
Unit testing is a validation and verification methodology where the developers test the individual units of source code. Some key points to be remembered from: –

• A unit is the smallest part of the application which can be tested. So it can be either a method. Function or class.
• These tests are conducted during development.
• Unit test belongs to the white box testing category.

2) What Are The Different Ways By Which You Can Do Unit Testing With .net?
There are 2 primary/accepted ways of doing unit testing:-

• NUNIT
• Visual studio team edition test system

3) What is Code Coverage?
Code coverage is a metric that determines the number of lines of code validated successfully by a testing process, which helps to analyze how software is verified in depth. Of course, the ultimate aim of any software company is the development of software products for businesses. But, in order to achieve that goal, companies must ensure that all the essential quality features of the software they develop are accurate, maintainable, effective, trustworthy, and safe.

4) Tell some brief about Unit testing?
A unit test is a way to test a unit, the smallest code in a system that can logically be isolated. This is a function, a subroutine, a procedure, or a property in most programming languages. The single part of the definition is significant. Author Michael Feathers says in his book “Working Effectively with Legacy Code” that tests are not unit tests when relying on external systems: “If you talk to the database, you talk through the network, touch the file system, you need a system configuration, or you cannot run it simultaneously with any other test.”

5) How to check timeout testing, and write some code?
Here is the code from which we can check the timeout testing

@Test (timeout=10)
Public void infinity(){
While(true);
}

6) What is Branch Coverage?
Branch coverage is a test method to ensure that all access codes can be executed at least once each of the potential branches is executed from each decision point. In other words, every branch is right and wrong. In addition, it helps validate all the branches in the code to ensure that no branch results in abnormal application behavior.

7) What is the Advantage of unit testing?
There are many advantages of unit testing; some are UT simplifies the debugging process. UT forces better code and design, whether you use C#, Python, Java, JavaScript, or PHP. It means that you have a well-defined and cohesive code. Using unit testing and good unit testing tools, the total cost of a project is reduced. Early detection of bugs means fewer late changes and easier problems than if they were made later.

8) Who can perform Unit Testing?
The developers usually perform unit testing during the development phase. At the same time, unit testing is usually done by automation engineers and QA experts if developers are occupied with other development tasks.

9) How can Unit test cases be avoided?
It can help avoid long classes, procedures, functions, etc. when you are working with unit test cases. No long code is necessary, but the functionality of each small component needs to be tested step by step. It makes it easy to develop big apps.

10) List some various coverage code techniques
Here is the list of coverage code technique

• Condition coverage
• Statement coverage
• Decision coverage
• Branch Coverage

11) What does the term Refactoring mean?
This technique is used if you want to revamp any existing code. It is usually done in small steps in which the code alteration is not the functionality or logic. It also helps to correct bugs.

12) Tell me about Unit Testing in brief.
Unit Testing is used to check the independent modules of a software app during the development phase. An independent module can be anything like procedure, function, etc. Unit testing is done by developers and testers together before the integration testing. They have to write unit test cases as well if needed.

13) What is the total number of phases in a Unit Test Case?
The working of a unit test case can be divided into 3 phases. In the first stage, it will initialize the specific module of a software app that you want to test. In the second stage, it will execute the test case. In the end, it will analyze the final output.

14) What are the various types of Unit Testing for a software app?

• State-based Unit Testing
• Interaction-based Unit Testing

15) What do you know about state-based Unit Testing?
If you want to check if the final output is right or not, then it becomes state-based.

16) Tell me about interaction-based unit testing in brief.
If you want to check the behavior of functions or procedures, whether they are invoked in the right way or not then it is interaction-based.

17) Have you ever used or worked on Unit test frameworks? If yes, name them.
Yes, I do have practical knowledge of unit test frameworks, Junit, and TestNG.

18) Tell me about the Junit testing framework.
Several test cases need to be executed repeatedly. If you need test cases for repeated execution then the Junit framework can help you.

19) Who can perform Unit Testing?
Unit Testing is generally done during the development phase so that it can be performed by developers. At the same time, if developers are occupied with other development tasks then unit testing is generally performed by automation engineers and QA experts.

20) What do you know about the term Refactoring?
If you want to revamp any existing code, then this technique is used. It is generally done in small steps where only the code is changed, not the functionality of the logic. It helps in bug fixing too.

Hi everyone, today our topic is related to the software development lifecycle. In other words, what is the life cycle followed during software development? Everything we do in our day-to-day life has a lifecycle involved in it knowingly or unknowingly, we are following a lifecycle or a pattern. For example, we make tea or coffee everyday morning to power our day. What is the procedure for making tea boiling water adding milk adding tea powder adding some sugar? These are the following steps that everybody follows during the time of tea making. The method in which the ingredients are added is the life cycle of tea making process. Let’s see. What are the possible life cycles one can follow here some people boil the water first add milk add tea then add sugar that he is ready? For some others, the order is to add milk and water together bring it to boil then add some tea and then sugar. The rest part of them is in boiling water, add tea brew it well then add some milk to the taste, and then add sugar. So, we saw here the lifecycle involves the steps, which is adding a water milk tea powder for sure. The order in which you do? It is based on your preference. If you want to honor a no sugar diet or a diet or a diabetic person adding sugar becomes an optional step in this life cycle. But no matters what life cycle we follow all of us aim for just one thing a refreshing drink to get you started for the day. Similarly, when developing software. There are numerable steps to develop an ideal quality robust software. These ways of things have been identified and proven to work by experienced teams across the globe. So, let’s go through these seven inevitable processes with a software development lifecycle. Step number one is called planning,

Planning: Planning is where the stakeholder’s business team project manager’s program manager’s technical leads everyone sits together and plans on what needs to be built in simple terms the scope of the application and the milestones by which the software should be ready.

Step number two is

Analysis: Analysis where business analysts on the project will analyze the requirements and teachers that are expected out of the software in detail.

Step number three is

Design: This is the stage where the architects and technical team get involved. They participate in the designing process and decide the architecture of the solution.

Step number four is

Implementation: Finally, it is time to start developing the development team gets on it and starts building the software

Step number five is

Testing: Testing the software gets through a testing team cycle where they start finding defects or bugs. These all defects and bugs get assigned back to the development team, they fix and give them back for retest or testing. This cycle continues until the software is ready for deployment.

Step number six is

Acceptance: Once good quality software is ready. The software is ready to stakeholders for their approval if they are happy with it that means it’ll go signal the software can be deployed for being used by the end customers.

Step number seven and the last one after the deployment scene is called the maintenance base part

Maintenance: This is the part where the deployment team and the operations team. Always make sure that the software is running without bugs and always have been running in the environment.

So, these are the seven steps that we saw involved in the software development lifecycle.

Hi everyone, welcome to my course study on Jira software. In this course, you will learn everything about Jira software and I will explain to you each and everything about Jira software from a user perspective and from an admin perspective as well. So, before going forward, I would like to tell you this article is for people who are brand new to Jira. Jira is a very comprehensive tool with a lot of customizable capabilities and I would like to share one secret about how personally we use Jira, we use Jira to track our day-to-day activities and we love to use it to track our activities. For this article, I have certain agenda.

What is JIRA?

So, we move forward to know more about what is Jira? So, Jira is project management, issue-tracking, and bug-tracking tool. For agile software and business teams. It is made by a company and the company name is Atlassian. It is an Australian company but now they have different offices in many countries. Actually, the name “JIRA” is inherited from the Japanese word “Go Jira” which means “Godzilla”.   

Why should we use JIRA?

There are lots of software available in the market which are very similar to Jira then why should we use Jira? Why do the people in most of the organizations prefer to go with a Jira? So, the reason is it has everything that you need to manage projects and teams and is fully customizable to your needs, you can customize your workflow, add your custom issues types, you can add your fields, and design your issue operations screen as per your team requirements and countless adds-on to further enhance the functionality. Let me tell you about the marketplace of Jira where you can find various apps which are used to enhance the functionality of Jira. Let me tell you about the official website of Atlassian www.atlassian.com and you will click on the product tab, you will see on the right-hand side, you will have an option of the marketplace so, you will click on that and you will find multiple apps already available. You can filter as per the Atlassian products, if you will click on Jira then you will see lots of apps are available like tempo timesheet, automation for Jira, and many more so you can use any app according to your requirements so let’s move forward for another one. Features Jira has lots of features that make your life easier.    

What are the JIRA products?

The other one is what are the Jira products? Many peoples are not aware of like Jira is a family of products, built to help all types of teams track their work there are four products built on Jira platforms:

• Jira core
• Jira software
• Jira service Desk
• Jira Ops

I will tell you one by one what is the meaning and what are the features for these products so, let’s start with the first one Jira core, what is Jira core? It allows you to track issues using a customizable workflow which basically determines how issues can flow from start to completion and what are the other steps along with. This basic functionality that would you get with Jira core is the base bare minimum Jira tool that you can use for simple business-related products and task management. Let’s move forward to the next one and which is Jira software with Jira software which you will be using in this complete course. You have extra agile functionality where you can track software projects with agile methodology. In other words, Jira software includes both Jira core plus agile methodology. Now, what is the Jira service desk? It is a service desk that is used for support projects using the Jira service desk you can give a better experience to your customers they can easily ask for help and your agents can respond to them in a better way. The other one is Jira Ops, which is an incident management tool. It is used to centralize alerts and notify the right people at the right time so, these are the four products that come under the Jira platforms.  

Which agile methodology is used in JIRA?

Most of the people who start to learn Jira, who use to learn Jira has this question in their mind which agile methodology is used in Jira? So, I will tell you Jira software is an agile project management tool that supports any agile methodology, be it Scrum, Kanban, or your own unique flavor. You can use Scrum, Kanban, mixed methodologies, and agile scale up to your requirement but this software fit your framework scrum, Kanban, or your unique another one so, in this course you will focus on scrum and a little bit about Kanban as well because I saw most of the organization uses scrum, Kanban as well. I wish that you will get more core fundamentals about Jira methodology and it will more guide you in the future points of view.

Step 3:

How to start and shutdown Jira

Or you can also say the Jira tomcat server because Jira comes with the tomcat server so you will have to go to the bin directory inside the folder and you will find startup.SH and shutdown got SH files and these are the files that you will run to start and shutdown Jira server so, we will learn that you will go inside your folder and there you will see there will be bin directory and inside the bin, you will find that startup.SH and shut down. SH there you will have a startup.SH and there you will have a shutdown.SH so, to start you will go to the terminal and go to the location bin folder so for example, you will just press command on your keyboard to get that information and copy the location of that folder and then you will go to your terminal and you will change the directory to that bin folder of Jira and now you can say SH startup.SH and hit enter and you will see that information and it would show you tom get started and to check you can go to your browser and you can go to localhost 8080 so as of now it will not run or you may run this command again and yes, you will see the Jira server is up but there will some problem and it will say we cannot locate the Jira home directory so you will have to set up the home directory so what you will do you will shut it down so you will say sh shutdown.SH and tomcat will stop so if you go to localhost 8080 now so you will see the server will be stopped and you will learn how to set up the home directory and that you have already seen that you will go to localhost 8080.

Step 4:

How to set home directory

To check if the Jira has server is running and to set the home directory you will have to go to that file Jira application. Properties which is inside web-inf glasses folder and  

Go to file Jira-application .properties located in Jira folder >> Atlassian–Jira >> Web-INF>> classes

there you will have to provide a location for Jira home so you will see how to do that so you will go to the Jira folder and you will have to go to atlassian Jira folder there you will have web-inf and there you will have classes and there you would find a file Jira application properties so you can open that file with any text editor on your system if you have a text wrangler, you will open this and you will see it will ask for your location for Jira home so you can create any folder and then provide that folder as Jira home so you will create a folder on your desktop itself and you will name that folder as Jira Home hit enter and just press command I to copy its location and you will give the same location on that file, you will give that location so that will Jira home and you can save it and close it okay and see you if you will open this folder as of now that will empty but as you will now start your Jira servers you will see there are folders and files getting created there all the logs will get there as well so now you will go back to your terminal and again say SH startup.asset and it’s storm get started you will go to your browser localhost 8080 you will run the start command again and you will go to localhost 8080 and now you will see atlassian Jira is starting up so it means it will take up your home directory as well it might take a few seconds to start up also if you will now go to your Jira home folder you will inside the folder and you can see all these logs and all these information will now getting created inside that folder. Now, for the first time, it will have this information if you want to set it up yourself or you want to set it up for me so, this is our next step.

Step 5:

Setup Jira for use

You will have to set up Jira for use so you will have started your Jira server and now you will complete the setup so you can click on set it up for me and continue there you will have to select the product so you will select Jira software and select Jira software server you can name any organization there up and running and then generate license so there it will give you the information of your license you will say yes confirmation and there it will ask you for some email ids and then password and retype the password so you will give some email id there and password say next so now it will finally set up all the instances and everything that Jira requires on that particular machine so you will wait for few seconds for that setup to get completed meantime you will look at some tips so instead of localhost you can also use the IP 127.0.0.1 which is the Ip for localhost or you can also use your system public IP instead of localhost so instead of localhost there you can use that IP and you will now see the Jira will ready to go and you can get started with Jira. I hope this information will be helpful for you and it will give you privileges as an onboarding learning concept with valuable steps.

Before we start let’s talk about what is SRE. SRE is the one who works with the software engineers with the collaboration between developers and operation teams.

SRE is a practice that combines both software development skills and mindset to IT operations. The main focus of SRE is to enhance the reliability and performance of applications, with automation and continuous integration and delivery.

SRE has changed the traditional way of working as an operation team by incorporating new technologies, ideas, and methods. SRE was originated at Google.

After originated more than 1000 SRE engineers employed at Google. Even though after spread about SRE, other software companies also started adopting SRE engineers gradually. As per the 2021 report, 22% of organizations in a survey of 2,000 respondents have adopted the SRE model.

SRE accepts failure because they know failure is a part of success and not a single system is perfect. SRE and DevOps both work to bridge the gap between development and operations teams to deliver faster services. SRE has removed the “silos” between development and operation teams to function effectively.

SRE also works with the DevOps team to help them in operational works to give reliable service to the customer.

SRE Skillsets

SRE is a role that requires a software developer with operational experience or as a system admin or engineer for an IT operations role that has software development skills as well.

SRE needs some skillsets to have are-

Deep knowledge of version control.

Sound knowledge of operating Systems (like LINUX).

Should be aware of DevOps concepts and best practices.

CI/CD implementation expertise.

Issue troubleshooting experience.

Communication & Collaboration skills.

Good knowledge of Cloud-native applications.

Good understanding of “Distributed computing”

Should know “coding”

Even though with these skills they should know tools sets as well which will be used by the SRE team.

Some toolsets are –

S.no       Problems                                        Tools                           

1              Operating Systems              –               Centos/Ubuntu & VirtualBox & Vagrant

2              Cloud                                   –                 AWS

3              Containers                           –                Docker & Kubernetes – Helm

4              Planning and Designing –             –                Jira & Confluence

5              Source Code Versioning                –            –                   Git using Github

6              Webserver                          –                    Apache HTTP & Nginx

7              Configuration & Deployment Management            –            Ansible

8              Infrastructure Coding                            –           Terraform

9              Services mesh Data planes & Control Planes            –      Envoy & Istio

10           Network configurations and Service Discovery         –        Consul

11           Continuous Integration                  –                   Jenkins

13           Infrastructure Monitoring                   –            Datadog, Prometheus with Grafana

14           Log Monitoring                  –                   Splunk & ELK stake

15           Performance & RUM Monitoring                   –                 NewRelic

16    Emergency Response & Alerting & Chat & Notification – SMTP, SES, SNS, Pagerduty & Slack    

SRE Roles and responsibilities. 

SRE teams are responsible for how code is deployed, configured, and monitored, as well as the availability, latency, change management, emergency response, and management capacity of services in production.

SRE helps teams to determine what new features can be incorporated and when by using service-level agreements (SLAs) to define the required reliability of the system through service-level indicators (SLI) and service-level objectives (SLO).

SRE takes back the collected data to the development team to fix the issue (means the vulnerabilities which shouldn’t be there while development) and not make it again next time.

Monitoring and logging are keys to SRE roles. In monitoring, they are keeping track of what’s happening in real-time. Logging is an archive of what has happened, so you can examine it later.

Monitoring will give you the ability to anticipate failures and see them coming, so you can proactively solve them.

Logging is like, when you get an unanticipated failure, it makes you get back and see what happened. So you can do RCA (Root cause analysis) and find out how to solve it, not for now but for the future.

So as an SRE expert you are responsible to monitor the product and fixing the issues, bugs, blot wares, etc by the use of automation to eliminate some extent of manual work. 

Automation is an essential part of the SRE. With automation, we can reduce the manual work even though fix the issue on which we have to work again n again. This also helps to reduce the toil.

Maintaining the balance between operations and development work is also one of the roles of SRE.

Nexus – Nexus is a repository manager which allows the proxy, collect and manage the dependencies.
It makes it easy to distribute the software.

Nexus is best to organize, store and distribute software components.

It delivers safer, faster, and better software with an automated software supply chain.

The Sonatype Nexus is an open-source tool which having 527 GitHub stars and 237 GitHub forks.

The Nexus platforms are more than 80% accurate than Jfrog Artifactory. Nexus provides universal support and is suitable with popular tools like Eclipse, Hudson, Jenkins, Puppet, Chef, Docker Etc.

Nexus has vast format coverage and supports all important languages and ecosystems.

Nexus repository is a robust package registry to all docker images and Helm chart repositories.

Artifactory – Artifactory is a universal repository manager. It integrates with the ecosystem and manages binaries and provides consistency to CI/CD workflow.

Artifactory is a tool that collaborates codes and version control. It supports all types of available software packages, enabling automated continuous integration and delivery.

Artifactory discloses a vast REST API that offers access to its features in the development cycle. Through API it is possible to manage builds, repositories, and artifacts and can perform searches, apply configurations, perform maintenance tasks, and many more.

Artifactory Query Language (AQL) gives you unusual flexibility to search for artifacts. It provides the easiest way to prepare queries that state any number of search criteria, filters, sorting options, and output fields.

Artifactory manages, configure and monitor DevOps services in the organization through a single pane of glass.

Differences between Sonatype Nexus and Artifactory

Artifactory is a tool that can be classified in the ‘Code Collaboration & Version Control’ category, whereas Sonatype Nexus is grouped under ‘Java Build Tools’.

According to the StackShare community, Sonatype Nexus has a wider approval, being mentioned in 49 company stacks and 16 developers stacks in comparison to JFrog Artifactory, which is listed in 16 companies stacks and 11 developer stacks.

Artifactory provides multi-cloud as well as hybrid cloud solutions whereas Nexus only supports on-prem.

Artifactory offers all the rest of the API endpoints which is needed for development, QA/QC, CI/CD, distribution, and deployment processes which Nexus doesn’t.

Artifactory stores exhaustive build-information for all builds (software bill of materials, or SBOM), it hosts and provides artifactory Query Language (AQL), an easy, and highly flexible tool to search for artifacts based on this ampleness of meta-data. There is no other repository manager that provides such extensive use of meta-data even Nexus as well.

Artifactory supports all major cloud storage providers (AWS, GCS, Azure Blob storage) and filestore sharding as well. But unfortunately, Nexus doesn’t support all these.

Artifactory supports a variety of replication modes ( pulled replication through a remote proxy, Active push replication to a single target, Active simultaneous push replication to multiple targets, event-based pull replication ) to support the different multi-site topologies of your global DevOps processes. Nexus only support pull replication through remote proxy.

Artifactory uses Derby DB by default whereas, Nexus uses a file system to store artifacts and metadata.

Artifactory and Nexus both allow searching by keywords, classes within artifacts, and GAV ( Group, Artifact, and version ) but in Artifactory its GAVC where can also be searched by a classifier.

Artifactory has various policy options to handle bad and missing checksums whereas Nexus involves specific permissions to restrict a repository browsing as well as searching through the web browser.

Auditing is much easier by using Artifactory, which involves an access log for the security-related incident. Especially logins, artifacts downloads, and deployments. This log can be viewed from the Artifactory UI and can be downloaded. Nexus logs don’t incorporate such detailed information, at least not in a separate way.

Nexus on the other side involves a special feature of RSS feeds for special events, such as for downloaded and deployed artifacts, logins, system configuration changes, and checksum errors. Artifactory doesn’t support RSS feeds.

Artifactory has no built-in special mechanism for removing artifacts after certain parameters e.g:- Lat use, path, tag, etc. whereas Sonatype Nexus has a built-in mechanism to support clearing up repositories.

To get trained and certification in both the tools there is a platform that is one of the best institutes DevOpsSchool. It claims to have the best and skillful trainers who hold a good experience, friendly environment, and practical projects that can help you guys to boost your carrier. So in my recommendation, if you are looking for an institute then it’s best in my consideration. Check once, guys.
