AWS App Mesh
AWS App Mesh is a service mesh that provides application-level networking to make it easy for services to communicate with each other across multiple types of compute infrastructure. It standardizes how services communicate, giving end-to-end visibility and ensuring high-availability for applications. It works with services running on Amazon ECS, Amazon EKS, AWS Fargate, and Amazon EC2.
Developers should use AWS App Mesh when building microservices architectures on AWS to manage service-to-service communication, traffic routing, and observability without modifying application code. It's particularly valuable for implementing canary deployments, A/B testing, and fault injection in production environments, as it provides fine-grained control over traffic flow and integrates with monitoring tools like AWS CloudWatch and X-Ray.
