Most of us are using AWS Cloud for developing and deploying web applications with a huge concern on the performance. If it is bothering you all the time, fix it now! Here are the top 5 simple tips for improving your web applications performance and scalability.
A good performance is critical to ensure better user experience because faster performance leads to more user engagement on your web applications.
Elastic Load Balancer Level SSL Termination:
Many web applications use SSL for securely transmitting information from browser to web servers. However, SSL requires multiple handshakes, content encryption/decryption for each request. So, it would put an additional load on your web servers. If your web application is using SSL and deployed on AWS cloud then we recommend you to terminate SSL at Elastic Load Balancer (ELB) layer instead of your web/application servers. This will reduce the CPU load on your web servers and improve application response times.
Enable Compression For Static Resources:
Whether you are serving static content like images, JS, CSS or JSON/text files via CloudFront CDN or web servers, it’s recommended to ensure that static content compression is enabled. With content compression on server side, the static file sizes will be reduced to improve the download performance and help you save on bandwidth costs as well.
Enable Browser Caching Headers:
Leverage Browser Parallelism:
Most of the modern web browsers can make 3 to 6 parallel connections to a particular domain at a given point. If your application uses many static resources like images, files, styles etc, then it’s recommended to use multiple domains like images1.myappdomain.com, images2.myappdomain.com, static.myappdomain.com to parallelise browser download of resources. All these domain can point to the same backend infrastructure like CloudFront distribution or ELB but browsers will essentially make more parallel connections to fetch resources as you are using multiple domains aliases for static resources and make your web application load faster.
Performance Review Your Web Application:
You should use tools like YSlow, PageSpeed, DynaTrace etc to analyse your web application performance and implement the recommended best practices. Many web application in AWS Cloud optimization techniques are easy to implement and will help you in achieving a better user experience.
Importance of Instance Families:
Choose new generation instance families like M3, C4 and R3 for your workloads. It makes sense to choose few types of instance families, so you can roll up and roll down the machine types based on future usage.
Hope this article helps, if you are actively using AWS Cloud infrastructure then check out Botmetric to improve your operational efficiency and simplify day to day operational tasks. Botmetric also helps you perform performance audit of AWS ELB and AWS RDS which are often the main source of web application’s latency issues.
