In modern software architecture—especially with the rise of microservices—efficient request routing and system scalability are critical. Two key components that help manage this are the API Gateway and the Load Balancer.
When designing scalable systems, one of the most critical decisions you'll face is how to distribute traffic across your servers. Two core models are widely used, stateless and stateful load balancing.
In today's always-on digital world, downtime is unacceptable. Whether you're running a SaaS platform, an e-commerce site, or an enterprise application, ensuring high availability (HA) and fault tolerance for your infrastructure—especially your load balancers—is non-negotiable.
Load balancers are critical for modern web applications. They help distribute incoming traffic across multiple servers, improve performance, and ensure high availability. However, like any technology, load balancers can present challenges if not implemented correctly.
