Envoy is the engine that keeps Istio running. If you’re familiar with Istio, you know that the collection of all Envoys in the Istio service mesh is also referred to as the data plane.
In this blog post, we’ll look at the fundamentals of Envoy: the building blocks of the proxy and, at a high level, how the proxy works. Understanding this will help you better understand how Istio works.
WebAssembly (Wasm) has many applications in the cloud-native world today – WASI, edge cloud computing, Proxy-Wasm, and cloud-native runtime for serverless functions, to name a few. The question is, why has WebAssembly become so popular?
On July 13th Envoy proxy announced the 1.19 release. Envoy is an edge and service proxy that is a fundamental component of the Istio platform. The 1.19 release includes several new features, minor behavior changes, and bug fixes.
If you’ve ever wondered what WebAssembly (Wasm) is and how it fits into the service mesh ecosystem, this is the article you want to read. You’ll learn about Envoy extensibility and Wasm extensions.
Years ago when I heard WebAssembly (Wasm) for the first time, I was intrigued. The fact that I can write code in Rust or C++ and have it running in a browser blew my mind immediately. Porting an existing browser-side computation from JS code to Rust results in an increased performance. Needless to say, I have high expectations from this technology. Sadly, due to personal circumstances, I haven’t had much time and opportunity to explore this technology further.
That is, until last week.
In light of the collaboration that marks the cloud native community’s approach to today’s distributed workplaces and environments, the title hashtag of KubeConEU 2021 was #TeamCloudNative. This year’s virtual conference brought together this massive community and included hundreds of sessions and 11 distinct Zero Day co-located events.
Want to observe a service mesh that extends to virtual machines? A new analyzer in Apache SkyWalking — the APM system designed especially for microservices, cloud native and container-based architectures — leverages Envoy’s metadata exchange mechanism to work in Kubernetes, VM, or hybrid environments.
Envoy Proxy has announced the release of 1.17. The new version released on Jan. 11, 2021 brought a breaking change: v2 API is deprecated.
One of Envoy’s many powers is traffic routing and load balancing. For any dynamic environment that’s subject to regular changes, it needs a dynamic configuration mechanism that is capable of enabling users to make those changes easily, and most importantly, with no downtime.
The 3rd annual Envoy-Con, a practitioner-driven community conference organized by the Linux Foundation, was held virtually today and attended by a few hundred developers and end users who have adopted Envoy, the edge and service proxy. Envoy is a widely adopted open source project that can be used in various deployment scenarios, including as a load balancer and as a service mesh data plane.
