your fights, start small Stabilizing Istio Start with few simple features such as: ● Injecting sidecars, HTTP/2 LoadBalancing ● Traffic shifting for canaries Build confidence in the system and understanding First, headless services, now labels... Who said that migrating to Istio is only about adding sidecars?? 50 Label selector updates for app and version labels Adopting Istio Fair enough, let’s do the IstioOperator manifest. 55 Istio proxy performance and capacity Adopting Istio ● Putting sidecars everywhere has a cost ○ Latency ○ Compute resources The Istio 1.9 community reference values

leverages Istio as its service mesh, and one aspect of Istio is its reliance on sidecars for secure network communication. Sidecars, which are language agnostic, act as service proxies and allow for all traffic container. The second benefit is that sidecars are injected automatically, no matter the workload. This means that even if your software team does not know about sidecars, they are still going to utilize benefits. This is what baked-in security looks like in practice. 3. Enforce zero-trust security 4. Sidecars enable better security A platform is an intricate system and it cannot be bought ready made from

“distroless” version of it’s Docker image which builds a minimal, hardened version that can be used for Sidecars. These types of security controls should not be optional. Reproduction Steps Attach to a Pod that Distroless image which can be used by other Istio control plane components (like Pilot) as well as the sidecars used by Pods and workloads. Make this configuration the default option for all systems possible on how to disable them when users want to opt-out of these controls. This should be enabled for Sidecars and services within the Istio control plan as well. 23 | Google Istio Security Assessment Google

Instead, they can also be used to directly sign arbitrary certificates and communicate with other sidecars. HTTP request: POST /mutate HTTP/2 Host: 10.0.42.140 Content-Type: application/json Content-Length:

The data plane handles the connection between services and forms a series of proxies deployed as sidecars. The proxies consist of Envoy proxies and an Istio-agent and manage network traffic between microservices
