Here’s a service mesh in Kubernetes works. This model is also known as sidecar deployment and hence named as “sidecar proxy”. In order to minimize the additional latency, the proxy needs to be run on the same machine or in the same pod as the service, for which it was proxying so that they can communicate over the local host. This is why the service mesh adds an extra hop to every call. But for this to happen, it’s important that each data plane must connect to the control plane for getting themselves registered and for receiving the configuration details.Įvery call within the Microservices architecture goes through a proxy. The control plane within the service mesh architecture manifests an interface to the users so that they can configure the behavior of proxies within the data plane using policies and make that configuration available to other proxies via another API. This means there would be an equal number of proxies that need to be taken care of and this is how the control plane comes into the picture. In a microservice-based architecture that comprises hundreds of services, each service needs to be replicated as per the requirements. The proxy then applies rules of authentication, authorization, encryption, rate-limiting and load balancing, handles service discovery, and implements logging and tracing.Īs seen above, the service mesh architecture needs a proxy for each instance of a service. All service calls moving to and from a service go through these proxies.

These network proxies are deployed alongside each instance of a service that needs to communicate with the other services in the system. In the service mesh architecture, the data plane refers to the network proxies. Let’s take a quick look at these components of the service mesh architecture. While the data plane controls and manages the actual forwarding of the traffic, the control plane provides the configuration and coordination. Here’s what a service mesh architecture looks like and what components it comprises. Moreover, it can be used to implement features such as encryption, logging, tracing and load balancing, thereby improving the security, reliability and observability of the entire application.Ĭomponents of a Service Mesh Architecture! This visible infrastructure layer can document how well (or not) different parts of an app interact, so it becomes easier to optimize communication and avoid downtime as an app scales, ensuring communication among the services in the containerized infrastructure is fast, reliable, and secure. Unlike other systems present to manage this type of communication, a service mesh is a dedicated infrastructure layer that is built right into an application.

A service mesh is a configurable and dedicated infrastructure layer for managing service-to-service network communications within the cloud environment.Ī service mesh controls and monitors how different parts of an application share data with one another.

This is how a Service mesh such as an open-source project Istio service mesh can help resolve the issue. Furthermore, problems may get aggravated as many services are involved in the overall functioning of the Microservices-based applications. Performance issues, security, load balancing problems, tracing the service calls, or proper observability of the service calls are some issues that might occur while handling Microservices. This can pose serious issues if the problems are not detected at the right time and properly.

Whenever there is a service call from one Microservice to another, it’s abstruse for the DevOps teams to infer or debug what’s happening inside the networked service calls. Services within the Microservices-based architecture being modular in nature are difficult to manage.

Let’s read and explore more on Service Mesh, its architecture, components and popular solutions for service meshes, here in this article. The use of Service mesh in Kubernetes is the most thought-after step to overcome security and networking challenges obstructing Kubernetes deployment and container adoption. With the popularization of microservices architectures, there has emerged the need of using a Service Mesh. – An Introduction to ISTIO Service Mesh & its Architecture! – The Benefits of Deploying a Service Mesh You can read about Service Mesh, the benefits of deploying a Service Mesh, and ISTIO architecture, here in the given links! In its 2020 Cloud-Native Survey most recent report, The Cloud Native Computing Foundation (CNCF) found that the use of service mesh in production jumped 50% in the last year.
