Introduction to AWS App Mesh and its use cases

In this recipe, we will learn about AWS App Mesh. We will also learn about the use cases of AWS App Mesh.

Recipe Objective - Introduction to AWS App Mesh and its use cases?

The AWS App Mesh is a widely used service and is defined as a service mesh that provides application-level networking to help users' services connect across numerous types of computing equipment. App Mesh enables users' applications end-to-end visibility and excellent availability. The majority of modern apps are made up of many services. Various forms of computing infrastructure, such as Amazon EC2, Amazon ECS, Amazon EKS, and AWS Fargate, can be used to build each service. It gets more difficult to detect the specific site of faults, reroute traffic after failures, and reliably deploy code modifications as the number of services within an application grows. Previously, users had to write monitoring and control logic directly into your code and re-deploy their service whenever something changed. AWS App Mesh makes running services simple by giving you consistent visibility and network traffic controls, as well as assisting you in delivering secure services. To alter how monitoring data is collected or traffic is routed between services, App Mesh eliminates the need to rewrite application code. App Mesh configures each service to export monitoring data and applies consistent communications control logic to your whole application. App Mesh may be used with AWS Fargate, Amazon EC2, Amazon ECS, Amazon EKS, and AWS Kubernetes to help you grow the user's application. For on-premises apps, App Mesh also connects with AWS Outposts. App Mesh is compatible with a wide range of AWS partner and open source technologies because it leverages the open source Envoy proxy.

Benefits of AWS App Mesh

  • All of the user's applications' metrics, logs, and traces are collected by App Mesh. For monitoring and tracing, you can combine and export this data to Amazon CloudWatch, AWS X-Ray, and compatible AWS partner and community tools. This allows you to easily detect and isolate problems with any service, allowing you to improve your entire programme and thus offer end-to-end visibility. App Mesh gives users the ability to customise and standardise how data flows between their services. Custom traffic routing rules can be simply implemented to ensure that user service is highly available throughout deployments, after failures, and as their application scales. To run their application, users won't need to define communication protocols for each service, write custom code, or use libraries and thus streamlining the operations. Even when services are in the private networks, App Mesh can assist encrypt all queries between them. Users can also add authentication rules to make sure that only the services they allow connect and thus enhances the network security.

System Requirements

  • Any Operating System(Mac, Windows, Linux)

This recipe explains AWS App Mesh and uses cases of AWS App Mesh.

Use cases of AWS App Mesh

    • It provides a use case of being fully managed

AWS App Mesh is a managed and highly available offering from Amazon Web Services. App Mesh enables users to manage service communications without having to deploy or manage communications infrastructure at the application level.

    • It provides a use case of container orchestration native to user experience

AApp Mesh integrates with Amazon ECS, Amazon EKS, AWS Fargate, and EC2 Kubernetes services. Users add the provided App Mesh proxy as part of the task or pod specification for each microservice for containerized workloads operating on ECS, EKS, Fargate, or Kubernetes, and configure the services' application container to communicate directly with the proxy. When the service is started, App Mesh checks in with the proxy and configures it.

    • It provides service-to-service Authentication

Mutual TLS (MLS) is a transport layer authentication protocol that enables service-to-service identity verification for application components running inside and outside service meshes. It enables customers to extend the security perimeter to AWS App Mesh applications by provisioning certificates from the AWS Certificate Manager Private Certificate Authority or a customer-managed Certificate Authority (CA) to workloads in the service mesh, as well as requiring automatic authentication for client applications connecting to services.
