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.

Planning for application modernization

Although applications are the core workload for modernization, modernizing infrastructure, data, processes, tools, practices, and culture for a successful application modernization program is also required. The planning process for application modernization is depicted in Figure 5.1:

Business value and roadmap

Application modernization aims to replace the existing legacy platform with a modern platform. The core characteristics of modern application platforms are defined based on the Business Value (BV) and roadmap. To determine the core BV, we should consider the following:

  • What applications can move to the cloud?
  • Where should applications land on the target – private as well as public cloud, Platform as a Service (PaaS), or Software as a Service (SaaS)?
  • What level of cloud enablement and modernization is required to move the applications?
  • Where to...
