The container orchestration framework keeps a list of instances that are ready to receive requests and provides the interface for DNS queries. Typically, the instance performs a DNS lookup for this purpose. When an instance needs to interact with a different service, it needs to find – discover – a healthy, available instance of the other service. Many service mesh implementations use a sidecar proxy to intercept and manage all ingress and egress traffic to the instance or pod. The sidecar communicates with other sidecar proxies and is managed by the orchestration framework. The purpose of the sidecar proxy is to route, or proxy, traffic to and from the container it runs alongside.

A sidecar proxy runs alongside a single instance or pod. Clients rarely access an instance or pod directly rather they access a service, which is a set of identical instances or pods ( replicas) that is scalable and fault‑tolerant. Sometimes the instance is a single container in Kubernetes, an instance is made up of a small group of interdependent containers (called a pod). An instance is a single running copy of a microservice. Services and instances (Kubernetes pods).Kubernetes seems to have cornered this market, with even its main competitors, Docker Swarm and Mesosphere DC/OS, offering integration with Kubernetes as an alternative. As more and more containers are added to an application’s infrastructure, a separate tool for monitoring and managing the set of containers – a container orchestration framework – becomes essential.

Service mesh comes with its own terminology for component services and functions:

Download NSM for free, try it out in your development and test environments, and give us your feedback on GitHub. Alternative architectures exist as well: Netflix’s technology suite is one such approach where service mesh functionality is provided by application libraries (Ribbon, Hysterix, Eureka, Archaius), and platforms such as Azure Service Fabric embed service mesh‑like functionality into the application framework.Įditor – NGINX Service Mesh (NSM), a fully integrated lightweight service mesh that leverages a data plane powered by NGINX Plus to manage container traffic in Kubernetes environments, is now available in a development release. The sidecar proxy pattern is most popular, as illustrated by projects from Buoyant, HashiCorp, Solo.io, and others. Istio is not the only option, and other service mesh implementations are also in development.

It will be interesting to see the value they can add to the open source project. Vendors are seeking to build commercial, supported versions of Istio. Kubernetes, which was originally designed by Google, is currently the only container orchestration framework supported by Istio. Istio, backed by Google, IBM, and Lyft, is currently the best‑known service mesh architecture.

This way, developers can handle development, support, and maintenance for the application code in the services operations teams can maintain the service mesh and run the app. Sidecars handle interservice communications, monitoring, and security‑related concerns – indeed, anything that can be abstracted away from the individual services.

The service mesh is usually implemented by providing a proxy instance, called a sidecar, for each service instance. The mesh provides critical capabilities including service discovery, load balancing, encryption, observability, traceability, authentication and authorization, and support for the circuit breaker pattern. A service mesh ensures that communication among containerized and often ephemeral application infrastructure services is fast, reliable, and secure. A service mesh is a configurable, low‑latency infrastructure layer designed to handle a high volume of network‑based interprocess communication among application infrastructure services using application programming interfaces (APIs).
