How does load balancing work in ECS?

Amazon ECS (Elastic Container Service) is a scalable vessel unity service that simplifies planting, managing, and spanning containerized operations. One of the most critical aspects of maintaining high vacuity and performance in ECS is effective cargo balancing.

Cargo balancing in ECS ensures that business is unevenly distributed across the holders (tasks) running in your ECS service. This is generally achieved using Elastic cargo Balancing (ELB), which automatically distributes incoming business among healthy tasks registered in one or further target groups.

There are two primary types of cargo balancers used with ECS: Application cargo Balancer (ALB) and Network cargo Balancer (NLB). ALB operates at the operation subcaste (Subcaste 7) and supports advanced routing mechanisms like host-based and path-based routing. This makes it ideal for microservices infrastructures where business needs to be directed to specific services.

On the other hand, NLB operates at the transport subcaste (Subcaste 4), offering ultra-low quiescence and high outturn for operations that bear extreme performance.

When using ECS with the Fargate launch type or the EC2 launch type, services can be linked directly to a cargo balancer. As tasks are added or removed, ECS automatically updates the target group to reflect the current healthy set of holders, icing a flawless stoner experience.
