Validating a Request Payload with Wasm

What is a Wasm Plugin?

A Wasm plugin lets you easily extend the functionality of your service mesh by adding custom code to the data path. Plugins can be written in the language of your choice. At present, there are Proxy-Wasm SDKs for AssemblyScript (TypeScript-ish), C++, Rust, Zig, and Go.

In this blog post we describe how to use a Wasm plugin to validate a request payload. This is an important use case for Wasm with Istio and an example of the many ways in which you can extend Istio using Wasm. You may be interested in reading our blog posts on using Wasm with Istio and viewing the recording of our free workshop on using Wasm in Istio and Envoy.

Istio Applies to Become a CNCF Project

Today, I am happy to announce that the Istio project is announcing its intention to join the Cloud Native Computing Foundation (CNCF). I am very excited for this next step of the Istio project as it will further Tetrate’s mission, which is also my personal mission, to make Istio the industry standard project for service mesh.

My cofounders and I created Tetrate for this cause, and I have been dedicated to it since we conceived of the idea of Istio five years ago in the corridors at Google. Since a large number of organizations rely on Istio as infrastructure for their cloud native journey, CNCF is a natural home for the project to co-exist alongside other CNCF projects such as Kubernetes, Envoy, gRPC, and more.

NIST-Tetrate 2022 Conference Talks: NIST Standards for Service Mesh

At the joint NIST-Tetrate conference this year on ZTA and DevSecOps for Cloud Native Applications, Tetrate founding engineer Zack Butcher offered a deep dive into new publications in the NIST SP 800-204 series that sets the standards on security for the use of microservices architecture for the US Government. In this article, we’ll provide a brief overview of Zack’s talk, with a link to a full recording for all the details.

Importance of Wasm in Istio

WasmPlugin API has recently been added to the Istio project as a new and improved mechanism for extensibility. Here at Tetrate, we’ve recently conducted a successful workshop called Istio Wasm workshop. Click here to watch the recording of the workshop and join the conversation on Slack.

We talked about WebAssembly and its importance in Istio and Envoy projects, and went through multiple practical labs using Proxy-Wasm Go SDK and func-e.

Launching Envoy Fundamentals, a training course to enable faster adoption of Envoy Proxy

Also published on: CNCF

Envoy Proxy, an open-source edge and service proxy, is a vital part of today’s modern, cloud-native application and is used in production by large companies like Booking.com, Pinterest, and Airbnb(Source). Tetrate, a top contributor to Envoy, has developed Envoy Fundamentals, free training with a completion certificate, to help enterprises adopt the technology faster. It will enable DevOps users, SREs, developers, and other community members to learn Envoy easily with concept text, practical labs, and quizzes. Tetrate is also the creator of the popular Istio Fundamentals training course and the open-source project Func-e, which makes it easier to adopt Envoy.

New in Istio 1.12: Wasm-based extensions and ecosystem

New WebAssembly infrastructure in Istio makes it easy to inject additional functionality into mesh deployments

Three years in the making, Istio now has a powerful extension mechanism for adding custom and third-party Wasm modules to sidecars in the mesh. Tetrate engineers Takeshi Yoneda and Lizan Zhou have been instrumental in making this happen. This post will cover the basics of Wasm in Istio and why it matters followed by a short tutorial on building your own Wasm plugin and deploying it to the mesh.

Why WebAssembly is innovative even outside the browser

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?

What can WebAssembly do for your Application Security and Extensibility

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.
