Top 10 Performance Tuning Tips for AWS EC2
Source – trainingzone.co.uk
Amazon Web services, popularly abbreviated as AWS, are recognised as the leading provider of cloud based computing services. It is a great platform for web application development.
AWS is used for mixed deployments and prototyping along with a number of optimizations. AWS solution architect is basically concerned to design cost-efficient, highly available, fault tolerant scalable systems. They also hold a good knowledge in deployment, data security, trouble shooting and managing effective designs and application infrastructure. You can choose to advance your AWS career with a diverse skill in designing distributed systems and applications on the AWS platform.
Here is some performance tuning tips:
1. Plan Well
The term “cloud hangover” is a common term described by the experts to assure the difficulties that come with a cloud deployment like some real time unexpected costs to support, run and maintain your cloud based app. This also considers data movement, high availability of a load-balancing, adaptable and robust reverse proxy server. Moreover, the AWS enhanced networking capability offers greater performance with lower latency.
2. Implement Load Balancing
This helps in distributing requests across various application servers. Load balancing is considered to be quite important in the cloud than anywhere else. The AWS Elastic Load Balancing potential distributes application traffic across multiple EC2 instances. It provides fault tolerance and adjusts seamlessly to the alterations in the sources and amount of traffic.
3. Dynamic Files and Cache Static
It is a very widely used method for performance improvement. Therefore, robust caching support in an AWS based application. Caching is useful in mitigating the effects of latency. It also offloads the application servers from the busy task of moving static files all around.
4. Monitor and Benchmark App Performance
Of course, cloud services vary widely from that of the traditional implementations. It is greatly accessed to set standards for performance. Set standards for page load te, initiated and completed transactions as well as other measurements. This will help a user to monitor resource utilisation.
5. Using a DevOps Approach
Operational practices and application development are useful in meeting the business and technical goals on the web. This includes security architecture as well as real-time responsiveness. This also allows the user to implement new variations in being easier and quicker way.
6. Partition Your Data
The data should be segregated in the form of tables and the related data ought to be kept together in separate columns. This partition can also act as virtual columns. This helps in reducing the amount of data being scanned per query, which in turn would help in improving performance.
7. Optimise The Joins
When you are joining the tables, make sure that they are specified on the right side of the worker nodes. You may also choose to stream the table and do the join. You can even cross join to join multiple tables together.
8. Unexpected EBS Disk I / O
ESB is considered as a storage device that is greatly used to back the network connected block storage. A careful read of the EBS documentation delivers a higher IOPS on an average. When I / O volume increase, their rate reaches the IOPS ceiling for that particular volume. Various I / O related metrics would help in raising a standard EBS volume.
9. Running Out of EC2 Memory
When a running application runs out of EC2 memory, it will trigger the worst problem in its overall performance. It would cease and crash functioning altogether. Many operating systems allow memory swapping in order to save the application from all such disputes, particularly from data crashing at the time of transfer. Memory consumption should be monitored at the OS level, leaking processes should be killed manually and swap volumes must be added to the AWS instance to avoid such troubles.
10. Maintenance and Service Interruptions
In order to ensure this trouble, make sure that the AWS mails are not being caught by spam filters in any way. Also, check the AWS account console regularly and its status page.
AWS EC2 is a bit prone to some performance problems; however, monitoring then will surely offer a lot of benefits for system administrators and developers.
