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.

Discovery and learning

The next step is to assess the cloud maturity model to understand the effort required to move to the next maturity level. Again, we need to run a holistic approach to identify the current state. The main goal of the discovery step is to understand the functional as well as non-functional requirements. We also need all essential functional and non-functional requirements for the target state. Figure 11.1 shows the target platform for a cloud modernization project. Here, the Java applications are moved from on-premises to the IBM cloud. At the end of the modernization taking place, some applications are chosen for retirement as shown in Figure 11.1:

Discovery and learning steps are often designed using the co-create phase in the IBM Garage practice. The goal here is to answer the following questions in the form of functional as well as non-functional...
