| Summary: | 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
