Achieving Digital Transformation Using Hybrid Cloud

By: Vikas Grover, Ishu Verma, Praveen Rajagopalan

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.

The differences between VMs and containers

We have looked into both VMs and containers. Both of them make multi-tenancy possible and increase resource utilization (CPU and memory). Now, we will look at what makes VM and containers different. Gaining a deeper understanding of VMs and containers can enable you to make informed decisions about which technology to use based on your organization’s architectural and business objectives. By having a more thorough understanding of these technologies, you can make more informed choices about when and how to utilize them. The following diagram shows VMs and containers next to each other and you can see how they differ at a high level.

VMs are traditionally used for monolith workloads. VMs are less portable than containers because of the dependence they have on the OS, applications, and libraries. VMs are mostly used for the following:
