1. Terraform is a tool used as infrastructure as code implementation. It give option to build, change, destroy resources efficient and safety way.

   It’s solution easy to manage with posibitliy to build and manage infrastructure on many different environments from one place using one coding language.

   Terraform contact using providers with chosed cloud or other vendors where interpreted commands from loaded files are transformed to executable code in destined environment.

   Providers – connectors from terraform executable to destined environment
   Workflow – write/plan/apply – types of action possible to perform
   Variable – variables used for hold data 
   Modules – addons expand functionality

   Terraform is a tool that helps creating changing destroying infrastructure, like servers networks etc by using code. It simplifies and speeds up the process of creating and changing infrastructure resources

   why do we need it

   terraform makes it possible define our infrastructure as code, making it more efficient , uniform and easier to maintain.

   how terraform works

   Terraform works by using HCL infrastructure code. It then connects with providers through cloud APIs. Terraform translates the HCL code into API calls through these providers, enabling infrastructure provisioning

5. What is Terraform?
   -terraform is an open source tool which can work with several different providers without learning their own management tools/languages. it saves cost , time and improves quality of work.

   Why do we need it?
   – It helps in managing resources across different provider using single code. No need to write codes for different providers in different languages. Management of infra becomes easy.

   How Terraform Works?
   -It works with plugins given by the providers to work with their APIs, which works as conversion tool between the terraform code and and provider APIs.

   What is 5 most imporant terminology used in terraform and explain in short
   – Providers : They are the platforms where infra is residing.
   – Resource : its is a part of infrastructure, like network, virtual machine, databse etc
   – Module : they are like containers of resources, which can be called via root module
   – statefile : it contains info in JSON format which is received from Provider API, which contains the state of resources.
   – Variables : it can be defined in several ways, and useful in managing huge infra.

    Why do we need it?Via one tool (terraform) you can connect to mulitiple providers (aws,awx,alibaba, vspehere,k8s) and create the needed infrastructure

    How Terraform Works?From 1 file terraform creates a plan and ask your approval create the infra you configured in the tf file. Terraform keeps the status in a state file. At any time , you can make change to your infra and/or can destroy and recreate. As said the state of your infra is kept in a state file.

11. What is Terraform?
    Terraform is infrastructure as a code tool. With different prodivers you can code with HCL and state how you want your infrastructure/resources to be and terraform with prodider will translate that to actual changes if needed.

    Why do we need it?
    With terraform we can tell wanted state of infrastructure and terraform code will then also be usable for documentation how infrastructure is configured.

    How Terraform Works?
    Terraform is binary program that you run in a folder that contains .tf files. Terraform will combine all .tf files into one and with prodider will translate those .tf files for example AWS or Azure api to do wanted changes.

    What is 5 most imporant terminology used in terraform and explain in short
    provider – Tells terraform which provider needs to be downloaded and which provider funtions are available to be used like, azurerm
    statefile – JSON file that containes current state of the resources modified with terraform
    resource – Tell terraform to create or configure specified resource with wanted settings
    data – Terraform will ask from prodider this resource but will not create it even if it does not exist
    module – Basically every folder is a module but to use other folders you need to tell module where is the source folder source = “./modules/testmodule”. With modules you can create reusable code that will contain all needed resources and configurations for them.

14. 1 What is Terraform? 

    Terraform is a HashiCorp open-source tool used to define, provision, and manage infrastructure as code.
    It uses a HCL language to describe the desired state of your infrastructure. Depending on provider abilities it can operate on components like virtual machines, storage, and networking.

    2 Why we need it?
    The terraform supports multiple cloud providers unifying infrastructure management to one tool. It greatly simplifies management.

    3 How Terraform Works?

    Terraform need few components to work.
     – terraform itself
     – provider
     – code : describing desired infrastructure state

    HCL code is translated to proper API calls which are executed on target environment. The response is json statefile, which is used in the future by terraform.

15. What is Terraform?
    A tool that can simplify/automate work with many INFRA services (e.g. AWS, GC, Azure, etc.)
    Why do we need it?
    Using Terraform tool and existing terraform modules, we can significantly save time for project implementation.
    How does Terraform work?
    Terraform uses modules to perform tasks/actions through providers to INFRA service we want to us.
    What are the 5 most important terms used in terraform and briefly explain
    A provider is a kind of adapter to access/connect to the necessary INFRA, a resource is an action (desire), a module is a set of necessary scripts and variables to perform a task, a project is a single directory in the terraform folder, a variable is a value that can be changed depending on our needs.

18. #What is Terraform?
    It’s a open source tool, which provide a way to do code for infra of multiple cloud container platforms.

    #Why do we need it?
    To have one code standard and one code spec, and make it easier to learn and manage infrastructure with code.

    #How Terraform Works?
    It translates the codes to the actual api calls to the clould provider, so we can create, update, delete the infrastructure resouce as we want. 

    #What is 5 most imporant terminology used in terraform and explain in short
    1. Resource: one part of infrastructure, such as vm instance, database, networks.
    2. Provider: responsible for translating code into API calls, such as aws, azurerm, google.
    3. STATEFILE: after apply the code, terraform writes the actual state of the infrastructure in a state file.
    4. Variables: define the parameter used in codes.
    5. Module: like a combination of codes, which can be reused and share in any tf file.

19. What is Terraform?
    Terraform is a tool that help us to write code to create, update and delete infraestructure resources in different providers using a common and easy lenguage that is “translate” to the propietary lenguage.
    Using terraform we can save costs, costs, etc.

    Why do we need it?
    We need to use because if we are going to work with different services providers it will be very time consuming to learn how to do the same task in their own API lenguages, and even if they used a common sixtaxis it will not work between them.
    and it helps us to automate all our task needed to manage our environments.

    How Terraform Works?
    It works by using a friendly ease lenguage called HCL that is translate it to the different API providers and interact with them and using their different advantages with just one code.

    What is 5 most important terminology used in terraform and explain in short.

    Providers. They are the different cloud providers that we can connect.
    Variables. it will help us to modify some aspects of our code without the need to modify our main code
    Modules. They are code already created by a terraform comunity to help us to do our work in a very fast way without the need to be do it by ourselfs.
    Workflows. It tells you the proper way work with Terraform and its different providers in order to automate our work
    API. It’s the interface created and publish by the different cloud providers to interact with them, that allow us to manipule and work with them.

    It’s using generalized language by which you can connect to each technologies’ APIs with the same code.

    Why do we need it?
    # Automating provisioning or changing infrastructure services on various platforms with one tool.
    We need it because everyone wants things to be done _now_ .

    How Terraform Works?
    # It is using configuration files ( using the developers’ – HashiCorp – own language, Hashicorp Configuration Language ) created by the user which is feeded to a terraform client application. 
    This is connecting to the terraform modules made by the platform provider, for example Amazon’s aws which then reaches your cloud instanse and makes the modifications you defined in the config file.
    The config file is idempotent, so you define what you need. Then it is checked against your actual environment, and if the desire and actual state differs, then modifications would be done.

22. Q1. What is Terraform?

    Terraform is an open source “Infrastructure as Code” tool, created by HashiCorp. A declarative coding tool, that allows you to build, change, and version infrastructure on cloud plateforms.

    Q2. Why do we need it?
    Terraform lets you define and manage your entire infrastructure via configuration files and version control. It accomplishes this by using the two main components of Terraform architecture: Core and Providers.

    Q3.How Terraform Works?
    Terraform generates a plan and prompts you for your approval before modifying your infrastructure. It also keeps track of your real infrastructure in a state file, which acts as a source of truth for your environment.

    Q4.What is 5 most important terminology used in terraform and explain in short

    Variables: Also used as input-variables, it is a key-value pair used by Terraform modules to allow customization.
    Provider: It is a plugin to interact with APIs of service and access its related resources.
    Module: It is a folder with Terraform templates where all the configurations are defined
    State: It consists of cached information about the infrastructure managed by Terraform and its related configurations.
    Resources: It refers to a block of one or more infrastructure objects (compute instances, virtual networks, etc.), which are used in configuring and managing the infrastructure.
    Data Source: It is implemented by providers to return information on external objects to terraform.
    Output Values: These are return values of a terraform module that can be used by other configurations.
    Plan: It is one of the stages where it determines what needs to be created, updated, or destroyed to move from the real/current state of the infrastructure to the desired state.
    Apply: It is one of the stages where it applies the changes in the real/current state of the infrastructure in order to move to the desired state.

24. What is Terraform?

    It is a provisioning tool that can create,modify and delete infrastructure.

    Why do we need it?
    We need it because it is it supporting multiple vendors like AWS,Google,Azure.
    and uses very simple language called hcl which can used to deploy infrastructure.

    How Terraform Works?
    It can be downloaded as a binary and kept in a folder and can be run from that location directly.
    we have to create a file with .tf extension and the what is the desired infra we have to type code the hcl format.
    once it is validated it can be applied and state is store in the json file.
    It works in apply,show and destroy nodes.

    What is 5 most important terminology used in terraform and explain in short.
    Plan: It is one of the stages where terraform compares infra real state and determines what is necessary to bring it to desired state.
    Apply: It is one of the stages in which real changes are applied to the infra to make them match their desired state.
    Output Values: These are return values of a terraform module that can be used by other configurations.
    Module: It is a folder with Terraform templates where all the configurations are defined
    State: It consists of cached information about the infrastructure managed by Terraform and its related configurations.
