Istio uses related open-source services like Envoy, a high-performance proxy that mediates all inbound and outbound service traffic, and Jaeger, a simple UI for visualizing and storing distributed traces that developers can use to debug their microservices. Istio is a popular Kubernetes-native mesh developed by Google, IBM, and Lyft that helps manage deployments, breeds resilience, and improves security in Kubernetes. How service meshes work: The Istio example A service mesh enables DevOps teams to manage their networking and security policies through code.

As application traffic grows, requests between these services can increase exponentially, requiring sophisticated routing capabilities to optimize the flow of data between the services and ensure the application continues to perform at a high level.įrom a secure communications standpoint, service meshes are useful for managing the secure TLS (mTLS) connections between services.īecause service meshes manage the communication layer, they allow developers to focus on adding business value with each service they build, rather than worrying about how each service communicates with all other services.įor DevOps teams that have an established production CI/CD pipeline, a service mesh can be essential for programmatically deploying apps and application infrastructure (Kubernetes) to manage source code and test automation tools like Git, Jenkins, Artifactory, or Selenium. In general, your organization can benefit from a service mesh if you have large-scale applications composed of many microservices. The control plane also provides an API so operators can easily manage traffic control, network resiliency, security and authentication, and custom telemetry data for each service.
Management processes make up the control plane, which coordinates the proxies’ behavior. Sidecar proxies make up a service mesh’s data plane, which manages the exchange of data between services. It controls the delivery of service requests to other services, performs load balancing, encrypts data, and discovers other services.Īlthough you can code the logic that governs communication directly into the microservices, a service mesh abstracts that logic into a parallel layer of infrastructure using a proxy called a sidecar, which runs alongside each service. What is a service mesh?Ī service mesh is a dedicated infrastructure layer built into an application that controls service-to-service communication in a microservices architecture.

Here’s what you need to know about service meshes and how to overcome their challenges. A service mesh can solve these problems, but it can also introduce its own issues. This becomes even more challenging when the application receives heavy traffic, because a single microservice might become overwhelmed if it receives too many requests too quickly.

This modular microservices-based approach to computing decouples applications from the underlying infrastructure to provide greater flexibility and durability, while enabling developers to build and update these applications faster and with less risk.īut that modularity and flexibility also bring complexity and challenges as applications grow to include many microservices that need to communicate with each other.
#What is kubernetes service mesh software
Kubernetes orchestrates ready-to-run software packages (containers) in pods, which are hosted on nodes (compute instances) that are organized in clusters. As monolithic applications have given way to cloud-connected microservices that perform distinct functions, containerized environments, such as the Kubernetes platform, have become the framework of choice.
If you are wondering what a service mesh is and whether you would benefit from having one, you likely have a mature Kubernetes environment running large cloud-native applications.
