Load Balancing Strategies
Understand different load balancing algorithms and their implementation for distributing traffic across multiple service instances.
What is Load Balancing?
Imagine a popular website with millions of users! A single server can't handle all that traffic. That's where Load Balancing comes in.
It's like a traffic cop for your servers, intelligently distributing incoming network traffic across multiple servers. This ensures no single server gets overloaded.
Why Load Balancers are Essential
Load balancers bring several key benefits to distributed systems:
- Improved Performance: Distributes load, preventing slow responses.
- Increased Availability: If one server fails, traffic is routed to others.
- Scalability: Easily add or remove servers without affecting users.
- Fault Tolerance: Automatically removes unhealthy servers from the pool.
