ping-up>Wrapping up</h2><p>The sidecar mode is what made Istio a great service mesh. However, the sidecar mode can also cause problems as it requires the app and sidecar containers to run in the same pod. Istio ambient mode implements communication among services through centralized proxies (ztunnel and waypoint). The ambient mode provides greater flexibility and scalability, reduces resource consumption as it doesn&rsquo;t require a sidecar for each pod in the mesh, and allows more precise configuration. T
