In the first part of our system design series, we introduced MarsExpress, a fictional startup tackling the challenge of scaling from a local entity to a global presence. We explored the initial steps of transitioning from a monolithic architecture to a scalable solution, setting the stage for future growth.
As we continue this journey, Part 2 focuses on the critical role of the caching layer. We’ll delve into the technological strategies and architectural decisions essential for implementing effective caching, which are crucial for handling millions of users efficiently. architectural decisions pivotal for scaling to meet the demands of millions.
