Best Practices for Building Scalable Web Applications

Building a web application that can scale to handle millions of users requires careful planning and the right architectural decisions from the start.

Core Principles of Scalable Architecture

Scalability is not an afterthought—it should be baked into your application from day one.

Microservices vs Monolith

Understanding when to use microservices architecture and when a well-designed monolith is the better choice is crucial for long-term success.

Caching Strategies

Implementing proper caching at various levels—browser, CDN, application, and database—can dramatically improve performance and reduce server load.

Database Optimization

From indexing strategies to read replicas, optimizing your database layer is essential for handling high traffic volumes.
