Amazon ECS Gateway is a managed resource that facilitates ingress networking by dynamically creating and maintaining Application Load Balancers (ALBs) within customer accounts. This solution allows platform teams to define organizational networking policies centrally and associate them with one or more ECS clusters, which application teams can then adopt without networking expertise.
The service supports host-based routing, enabling up to 25 services to share an ALB and thereby optimize infrastructure costs. ECS manages lifecycle operations of ALBs based on service attachment and detachment, and integrates with monitoring tools like CloudWatch to provide traffic and health insight. ECS Gateway is available in all commercial AWS Regions at no extra charge aside from underlying infrastructure costs.
