Problem Statement
They were growing their loan book and were beginning to process a large volume of applicants. They wanted their systems to be robust to handle the incoming traffic.
- The system should handle at least 2,000 concurrent users.
- Ensure 100% availability of the Application.
- Identify the issues by monitoring the application and infrastructure.
Solution
We Implemented horizontal auto scaling and set up tools to monitor infrastructure and applications.
- Horizontal autoscaling for application instances with minimum 2 Medium servers to max 4 Medium servers based on load
- Setup application load balancer
- Algorithm for instance switching is round robin
- Redis Cache enabled
- New loan applications were saved in Amazon S3
- Enabled Application Logging and monitoring using EKL
- Enabled Cloud watch to monitor Application infrastructure
- We designed and configured a blue green deployment using Dockers to reduce downtime and risk
Challenges
- There were session sharing issues between WordPress and PHP applications which had to be resolved.
- There were numerous challenges in WordPress Admin page handling and Sync between the servers
Results
- During the load testing performed after the upgrade, the application was able to handle more than 10,000hits/second.
- With horizontal auto scaling, we were able to optimize infrastructure costs
- We were able to proactively monitor and support the application using the tools set up.
- Reduced cycle time of testing and release process by ~50%
