- Layer 7 – This is the network layer that the service mesh works on.
- All of the above.
- False – The Istio control plane is not a single point of failure since applications can continue to run without a control plane,
- True – A true service mesh is formed through a data plane where there's an Envoy sidecar proxy next to each microservice, which helps achieve service mesh functions.
- False – Istio can span multiple Kubernetes clusters through a replicated control plane, a shared control plane using a single network and a shared control plane using a multi-network.
- True – At the time of writing, Istio service discovery integration with Consul is in its alpha phase.
- False – This should be the other way around. Pilot pushes configuration to Envoy, which manages traffic.
- False – Istio...

Overview of this book
Although microservices-based applications support DevOps and continuous delivery, they can also add to the complexity of testing and observability. The implementation of a service mesh architecture, however, allows you to secure, manage, and scale your microservices more efficiently. With the help of practical examples, this book demonstrates how to install, configure, and deploy an efficient service mesh for microservices in a Kubernetes environment.
You'll get started with a hands-on introduction to the concepts of cloud-native application management and service mesh architecture, before learning how to build your own Kubernetes environment. While exploring later chapters, you'll get to grips with the three major service mesh providers: Istio, Linkerd, and Consul. You'll be able to identify their specific functionalities, from traffic management, security, and certificate authority through to sidecar injections and observability.
By the end of this book, you will have developed the skills you need to effectively manage modern microservices-based applications.
