Overview
Service meshes, such as Istio, provide a lot of value to teams running microservices architectures or cloud workloads. But there are a few drawbacks. Most service meshes use a sidecar proxy to implement their capabilities, but sidecars introduce complexities that incur costly operation complexity and resource overhead. There is a solution.
This report introduces developers, software architects, and platform engineers to "ambient mode," a sidecar-less architecture that allows platform teams to run Istio without sidecars. Authors Lin Sun and Christian Posta explain how this sidecar-less data plane, developed by Solo.io and Google, improves the operational experience of adopting, deploying, upgrading, and generally managing Istio throughout its life as critical infrastructure.
This report will help you:
- Lower the barrier for service mesh adoption via sidecar-less Istio
- Understand sidecar-less Istio (ambient mode) and its architecture
- Learn what ambient mode is and how it works
- Adopt ambient mode incrementally
- Onboard workloads into the Istio service mesh without sidecars
- Configure policy for workloads in Istio ambient mode
- Learn how to adopt Istio without sidecars in production
- Explore Istio without sidecars in a testing environment
Lin Sun is head of open source at Solo.io and a CNCF TOC member and ambassador. She's worked on the Istio service mesh since the project began in 2017 and serves on the Istio Steering Committee and Technical Oversight Committee.
Christian Posta is vice president and global field CTO at Solo.io, as well as the author of Istio in Action and many other books about cloud native architecture. He's helped government and commercial enterprises create and deploy large-scale, cloud native, resilient, and distributed architectures.

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.Addison B.
I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.Amir M.
I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
