Executive Summary

Continuing the development of a musician networking platform which involved implementing new features, enhancing the existing ones, and fixing bugs/errors/issues in the platform by improving its efficiency and productivity along with making the platform responsive.

Problem Statement

Our client wanted us to design and create a social platform where each and every user is able to connect and interact with one another easily. He came to us after a bad experience with some other company and was expecting to continue the development by improving website performance as well as efficiency.
The platform had various bugs which needed to be fixed and some major features were to be added like payment service, OTP service, adding more security along with improving existing features. Performance of platform was being affected as there were some major issues like:
1. Deployment architecture- Everything was deployed on a single EC2 instance due to which there was a high amount of downtime. The performance was impacted more when the user base was increased.
2. The videos on his platform were taking a lot of time to load.

Our Solutions

1) We followed MVC architecture for developing REST API using express as middleware and mongoose for managing data in MongoDB. Authenticated API with jwt by using JSON web token package.
2) Added payment service in the platform by integrating stripe payment gateway with help of stripe package, created OTPs for security/validation which was communicated via SMS with help of Twilio.
3) To improve the performance, we deployed the backend on a separate ec2 instance with Nginx as reverse proxy and pm2 as process manager which comes with a built-in load balancer and helps to keep the application alive forever.
4) Installed Nginx on the server, and changed the Nginx.conf file configurations as per the requirement and it worked as a load balancing solution. Also replaced the lets encrypt SSL certificates with ACM(AWS Certificate Manager) to make certificate renewal, provision, and management process better as well as easy.
5) For adding new features to the platform, the frontend involved creating several components, services, directives, pipes, and modules in Angular.
6) To reduce the load time we implemented Lazy loading with help of Lazy load routes. The reason behind increased load time for videos was the use of video tag over secured protocol, to solve this we used iframe for rendering videos which proved to be much faster.
7) Changed the existing deployment architecture and moved the front-end to S3 so that load on the server can be reduced. We moved the front-end to S3 with CloudFront as CDN for speeding up the distribution of web content and improving performance.
