Service Mesh
A dedicated infrastructure layer that manages service-to-service communication in microservices architectures.
Description
In the AWS ecosystem, a service mesh is used to facilitate the communication between microservices in a cloud-native application. It provides critical capabilities such as traffic management, security, observability, and reliability without requiring changes to the application code. AWS offers a service mesh solution known as AWS App Mesh, which integrates seamlessly with other AWS services like Amazon ECS, Amazon EKS, and AWS Lambda. By abstracting the network layer, a service mesh allows developers to focus on writing business logic while the mesh handles issues like load balancing, service discovery, and failure recovery. Additionally, it can enforce security protocols, such as mutual TLS, to ensure secure communication between services. This architecture is crucial for organizations scaling their applications, as it promotes a more agile and resilient environment where services can evolve independently.
Examples
- AWS App Mesh: An AWS-managed service mesh that helps in managing microservices communication across AWS services.
- Linkerd: An open-source service mesh that can be deployed on AWS to provide observability and security features.
Additional Information
- Service meshes help in managing complex microservices architectures by providing a consistent way to secure, connect, and observe services.
- They can significantly reduce operational overhead by automating many networking tasks that would otherwise require manual intervention.
