Overview of this book

Hybrid cloud technology can be leveraged by organizations aiming to build next-gen applications while safeguarding prior technological investments. This book will help you explore different hybrid cloud architectural patterns, whether designing new projects or migrating legacy applications to the cloud. You'll learn about the key building blocks of hybrid cloud enabling you to deploy, manage, and secure applications and data while porting the workloads between environments without rebuilding. Further, you’ll explore Kubernetes, GitOps, and Layer 3/7 services to reduce operational complexity. You'll also learn about nuances of security and compliance in hybrid cloud followed by the economics of hybrid cloud. You’ll gain a deep understanding of the concepts with use cases from telecom 5G and industrial manufacturing, giving you a glimpse into real industry problems resolved by hybrid cloud, and unlocking millions of dollars of opportunities for enterprises. By the end of this book, you'll be well-equipped to design and develop efficient hybrid cloud strategies, lead conversations with senior IT and business executives, and succeed in hybrid cloud implementation or transformation opportunities.

Pod-to-service communication

Pods in Kubernetes are designed to be temporary and can be created, terminated, and scaled up or down based on the traffic demand. This means that the IP address of a pod can change frequently, making it difficult for clients to connect to them.

Kubernetes networking addresses this issue through the utilization of its service feature, which allocates a stable virtual IP address to the frontend for establishing connections with backend pods linked to the service. Additionally, the service distributes traffic directed toward this virtual IP to the group of related pods in a load-balanced manner.

Furthermore, a service tracks the IP address of a pod, so even if the pod’s IP address changes, clients can still connect to it without any problem because they are only communicating with the static virtual IP address of the service. This makes it possible for clients to connect...
