Service Meshes in the Cloud Native World. Service Mesh Products - A service mesh is a great problem solver when it comes to managing your cloud applications. How Does a Service Mesh Work? Hence the need for the service mesh. The increased complexity of the cloud-native world.
Microservices have taken center stage in the software industry. Transitioning from a monolith to a microservices-based architecture empowers companies to deploy their application more frequently, reliably, independently, and with scale without any hassle. This doesn’t mean everything is green in Microservice architecture; there are some problems that need to be addressed, just like while designing distributed systems. This is where the “Service Mesh” concept is getting pretty popular.
We have been thinking about breaking big monolithic applications into smaller applications for quite some time to ease software development and deployment. This chart below, borrowed from Burr Sutter’s talk titled “ 9 Steps to Awesome with Kubernetes,” explains Microservices evolution.

The introduction of the service mesh was mainly due to a perfect storm within the IT scene. When developers began developing distributed systems using a multi-language (polyglot) approach, they needed dynamic service discovery. Operations were required to handle the inevitable communication failures smoothly and enforce network policies. Platform teams started adopting container orchestration systems like Kubernetes and wanted to route traffic dynamically around the system using modern API-driven network proxies, such as Envoy.
In this article, take a look at the service mesh in the microservices world. The software industry has come a long journey and throughout this journey, Software Architecture has evolved a lot. Starting with 1-tier (Single-node), 2-tier (Client/ Server), 3-tier, and Distributed are some of the Software Architectural patterns we saw in this journey.
For teams to monitor, support, and to maintain these services is becoming a challenge so most enterprises have invested in some kind of microservices management tool.
Reading Time: 3 minutes Service mesh is a dedicated infrastructure layer for handling service to service communication. Basically, it's a way to control how different micro services deployed on kubernetes will manage secure communication and traffic between them with lot's of cross-cutting concerns like logging, security, etc.
In this article, we reveal Linkerd’s secret sauce: a lightning fast Rust proxy called simply Linkerd2-proxy. Unlike general purpose proxies such as Envoy, NGINX, and haproxy, the open source Linkerd2-proxy is designed to do only one thing and do it better than anyone else: be a service mesh sidecar proxy.
Microsoft has released open service mesh (OSM), an alpha service mesh implementation compliant with the SMI specification. OSM covers standard features of a service mesh like canary releases, secure communication, and application insights, similar to other service mesh implementations like Istio, Linkerd, or Consul. Additionally, the OSM team is in the process of donating the project to the CNCF.
