Mastering Service Mesh

By: Anjali Khatri, Vikram Khatri

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.

Chapter 17: Exploring the Security Features of Linkerd

  1. True The TLS between service-to-service communication is fully automatic in Linkerd.
  2. False The TLS between the Ingress gateway and the edge service of the application is the application user's responsibility.
  3. True The linkerd-identity component of Linkerd's control plane is the Certificate Authority (CA) for the data plane proxies.
  4. True The linkerd-identity component automatically rotates the certificates for linkerd-proxy in the data plane.
  5. False The linkerd-identity component doesn't automatically rotate certificate for its own CA.
  6. True You can use trusted certificates from your own CA for linkerd-identity, but only at the time of install.
  7. True You can change the trusted certificate of the control plane at any time, but it requires reinstalling...
