The Business Need

‘Extramarks’ interactive sessions provide deep, immersive learning through Learn-Practice-Test (LPT) Pedagogy. In this technology-driven time, Extramarks is constantly promoting independent learning for its stakeholders (parents, teachers & students) while maintaining continuity from school to home and ensuring effective communication among the stakeholders.

However, over the years, their application was running on standalone servers in the public domain to handle the incoming load. This made them dependent on the central server and possessed many security issues, undoubtedly making the application vulnerable to attacks and malware. The client was looking to cater to three prime requirements:

  • A solution that would automate their scaling.
  • Secure its application from any kind of attacks and,
  • Deploy their application at a faster pace.

The Solution

The Cloud Consultants at Rapyder designed the right solution and configuration that could support the seamless functioning of the application to overcome the challenges mentioned above. The consultants at Rapyder proposed the following solutions to achieve the desired results:

  • The servers were migrated to private subnets to make the application secure.
  •  AWS WAF was implemented with CloudFront to tackle the vulnerabilities of the website.
  •  AWS Auto Scaling was implemented to handle the load based on the incoming load on the servers.
  •  OWASP WAF rules such as Cross Site Match Conditions, Size constraint conditions, SQL injection, IP Match Conditions, and String regex Match Conditions were implemented to prevent further vulnerabilities.
  •  For new deployments to the server running in Auto Scaling groups, a script was written that the client would deploy the application on one static server and then run the custom script by Rapyder.
  •  The script was designed to take the AMI of the server and deploy it on Auto Scaling Group, ensuring that the new application was running successfully.

  •  With the implementation of AWS Auto Scaling, Extramarks achieved an ROI of up to 15% on AWS cost.
  •  Our scheduled scaling at peak times made them witness further savings of 10%.
