Cloud computing gave rise to a Cloud-native[1] approach for operating application software in the cloud, whereby applications are segmented into micro-services that can be designed and deployed independently of each other. This significantly increases application maintainability, reduces time to market, and helps leveraging cloud computing model. On the other hand, this approach increases the system level complexity of the application and poses new challenges, such as how services discover each other, and how application handles individual service upgrades. To support cloud-native paradigm, new development, deployment, and orchestration tools are created. One of such tools is Istio [2] service mesh, built to connect, secure, control, and observe services. While immensely useful to application developers, Istio is an additional layer in cloud compute platform software stack and is thus prone to failure or misuse.
