Load Balancing with ELB
Distribute incoming application traffic across multiple EC2 instances using Elastic Load Balancers (ELB) for improved availability and scalability.
What is Load Balancing?
Imagine a popular website. If millions of users try to access it at once, a single server can get overwhelmed. Load balancing helps distribute this traffic.
It's like a traffic cop for your servers, directing incoming requests to different servers to prevent any one server from becoming a bottleneck.
This improves performance, reliability, and availability of your applications.
Meet AWS Elastic Load Balancing
AWS offers a managed service called Elastic Load Balancing (ELB). It automatically distributes incoming application traffic across multiple targets, such as EC2 instances.
ELB handles the heavy lifting of scaling and managing the load balancer itself.
Key benefits include:
- High Availability: Distributes traffic across instances in different Availability Zones.
- Scalability: Automatically scales its own capacity to handle traffic spikes.
- Fault Tolerance: Detects unhealthy instances and routes traffic only to healthy ones.
