Key architectural patterns and considerations for designing robust and scalable backend infrastructure.
Building a backend system that can handle millions of users requires careful planning and the right architectural choices.
Microservices Architecture
Breaking down a monolithic application into smaller, independent services allows for better scalability and maintainability. Each service can be developed, deployed, and scaled independently.
Database Sharding
Sharding involves splitting a large database into smaller, more manageable pieces called shards. This distributes the load across multiple servers, improving performance and capacity.
Caching Strategies
Implement caching at various layers (CDN, application, database) to reduce latency and offload the database. Tools like Redis and Memcached are essential for high-performance caching.
