Hybrid Cloud Infrastructure and Operations Explained

By: Mansura Habiba

Overview of this book

Most organizations are now either moving to the cloud through modernization or building their apps in the cloud. Hybrid cloud is one of the best approaches for cloud migration and the modernization journey for any enterprise. This is why, along with coding skills, developers need to know the big picture of cloud footprint and be aware of the integration models between apps in a hybrid and multi-cloud infrastructure. This book represents an overview of your end-to-end journey to the cloud. To be future agnostic, the journey starts with a hybrid cloud. You'll gain an overall understanding of how to approach migration to the cloud using hybrid cloud technologies from IBM and Red Hat. Next, you’ll be able to explore the challenges, requirements (both functional and non-functional), and the process of app modernization for enterprises by analyzing various use cases. The book then provides you with insights into the different reference solutions for app modernization on the cloud, which will help you to learn how to design and implement patterns and best practices in your job. By the end of this book, you’ll be able to successfully modernize applications and cloud infrastructure in hyperscaler public clouds such as IBM and hybrid clouds using Red Hat technologies as well as develop secure applications for cloud environments.

Chapter 7: Designing and Implementing Networking in Hybrid Cloud Infrastructure

If application code does not follow specific characteristics for efficient and effective cloud infrastructures, it can become impossible to design a secure and high-performing networking communication platform. The success of the cloud mainly depends on the network design of the target platform. If we adopt lift-and-shift or rehost migration patterns and migrate them without refactoring, the cloud target platform might provide poor latency and throughput. Often, the cloud is blamed for the failure. However, in most cases, the legacy application implementation and the target platform’s networking design are the main reasons for poor performance. Therefore, this chapter discusses the main challenges and requirements for efficient network communication.

In this chapter, we will cover the following main topics:

  • Planning an efficient network solution
  • Exploring a reference solution for networking...
