What is service mesh in Kubernetes?

A service mesh is a configurable infrastructure layer for a microservices application. ... Istio, backed by Google, IBM, and Lyft, is currently the best‑known service mesh architecture. Kubernetes, which was originally designed by Google, is currently the only container orchestration framework supported by Istio.

Does Kubernetes have a service mesh?

The six Kubernetes service mesh options presented here have a few things in common: Protocol support: They all work with HTTP, HTTP/2, gRPC, TCP, and WebSockets. They all have basic security in the form of mTLS between proxies by default. Service meshes, by design, provide some form of load balancing.

What does a service mesh do?

A service mesh, like the open source project Istio, is a way to control how different parts of an application share data with one another. ... Each part of an app, called a “service,” relies on other services to give users what they want.

Why do we need service mesh in Kubernetes?

A service mesh provides a consistent way to connect, secure and observe microservices. Most service meshes are tightly integrated with an orchestration platform, commonly Kubernetes. ... The number of microservices you're running, as well as urgency and timing, can have an impact on your needs.

What is the best service mesh?

Below, here are the key features from nine service mesh offerings.

Who uses service mesh?

Who's Using Service Mesh

Results from the Voice of the Enterprise: DevOps, Workloads & Key Projects 2020 survey tell us that 16% of respondents had adopted service mesh across their entire IT organizations, and 20% had adopted service mesh at the team level.

Is Kong a service mesh?

Kong Mesh is the universal service mesh for enterprise organizations focused on simplicity and scalability with Kuma and Envoy. Kong's service mesh is unique in that it allows organizations to: Start, secure and scale with ease: Deploy a turn-key service mesh with a single command.

Is Nginx a service mesh?

NGINX Service Mesh (NSM) is a fully integrated lightweight service mesh that leverages a data plane powered by NGINX Plus to manage container traffic in Kubernetes environments.

Can Istio be used without Kubernetes?

In theory, yes. Istio components are designed to be 'platform independent'. ... If you want to use something less tied to Kubernetes you can take a look at Consul, although it doesn't have all the functionality Istio has, it has overlap with some of its features.

What problems does a service mesh solve?

A service mesh is a set of configurable proxies with built-in capabilities to handle inter-service communication and resiliency through configuration. It solves the networking and security challenges of operating microservices and moves them into the service mesh layer.

How do you implement service mesh?

To implement a service mesh, you can deploy a proxy alongside your services. This is also known as the sidecar pattern. The sidecars abstract the complexity away from the application and handle the functionalities like service discovery, traffic management, load balancing, circuit breaking, etc.

What is AWS service mesh?

AWS App Mesh is a service mesh that provides application-level networking to make it easy for your services to communicate with each other across multiple types of compute infrastructure. App Mesh gives end-to-end visibility and high-availability for your applications.
