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.

Assessing the modernization maturity level

The modernization maturity level helps you to understand the current state of the applications and foresee the risks, assumptions, issues, and dependencies of the modernization process. It helps to plan the next step for the modernization program efficiently. The higher the maturity level is for any organization, the lower the required effort and budget for modernization. Table 2.3 shows the modernization maturity model. The maturity model focuses on the maturity level of the current platform, applications, data, and day-two operations. An organization needs to scope different components in Table 2.3 based on the current maturity level. An organization can be at a different level for different components. For example, they can currently be on level 3 in terms of the platform, but their applications are containerized, so they are on level 5 for applications. The final scorecard is driving input for the modernization planning of the organization...
