Best Practices for Building Scalable Applications

Scalability is crucial for modern applications. This guide covers database optimization, caching strategies, load balancing, and microservices architecture to help you build systems that handle growth.

Database Optimization

Your database is often the first bottleneck. Proper indexing, query optimization, and strategic caching can dramatically improve performance.

Caching Strategies

Implementing multi-layer caching (client-side, CDN, server-side) can significantly reduce load on your database and improve response times.

Load Balancing

Distributing traffic across multiple servers ensures no single server becomes a bottleneck. Consider both horizontal and vertical scaling.

Microservices Architecture

Breaking your application into smaller, independent services allows you to scale specific components based on demand.
