Overview of this book

Google Cloud, the public cloud platform from Google, has a variety of networking options, which are instrumental in managing a networking architecture. This book will give you hands-on experience of implementing and securing networks in Google Cloud Platform (GCP). You will understand the basics of Google Cloud infrastructure and learn to design, plan, and prototype a network on GCP. After implementing a Virtual Private Cloud (VPC), you will configure network services and implement hybrid connectivity. Later, the book focuses on security, which forms an important aspect of a network. You will also get to grips with network security and learn to manage and monitor network operations in GCP. Finally, you will learn to optimize network resources and delve into advanced networking. The book also helps you to reinforce your knowledge with the help of mock tests featuring exam-like questions. By the end of this book, you will have gained a complete understanding of networking in Google Cloud and learned everything you need to pass the certification exam.

Understanding Istio and the service mesh

Application modernization nowadays requires us to have distributed microservice applications running on several infrastructures spread across multi-cloud and on-premises environments. Due to the distributed nature of these applications, interconnecting microservices has become very challenging and complicated. One of the most well-known and adopted solutions for microservice networking is Istio. Istio lets you easily interconnect microservices within a Kubernetes cluster in a sort of overlay network called a service mesh. The great thing about service meshes is that developers do not have to implement network functionalities to discover microservices, route traffic to and from a microservice, authenticate and authorize API calls, and monitor how traffic is flowing across your distributed application. Indeed, Istio has the following features:

  • Traffic management: You can decide how traffic and API calls can be routed across your service...
