At my previous position as a Full-Stack Developer with Technolight, I was tasked with designing a web application that could scale well due to their rapidly growing user base. The application was a social media platform which expected a significant rise in users.
I was part of a team that implemented Horizontal and Vertical scaling strategies to manage the anticipated growth. The applications' backend was designed on a microservices architecture, each running in its own Docker container, enabling independent scaling of individual components based on demand.
We utilized a serverless architecture using AWS Lambda to manage the increasing demand, allowing the service to handle requests without worrying about over or under-provisioning of servers. This resulted in a system that was highly scalable and resilient.
As a result, our application was successfully able to manage the massive influx of users. Stability and response times remained excellent even during peak traffic periods. This highlighted to me the importance and value of scalability in full-stack development.
