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.

Use cases for application modernization

In this section, we will go through some application modernization use cases. Migration projects usually have multiple stages, as shown in Figure 5.5. First, requirement and BV analysis should generate a set of migration decisions. Migration decisions depend on the application platform, runtime, objective KPIs, and other essential dependencies. It is essential to use automated, tool-based analysis to make the most suitable migration decision using different migration patterns along with standard practice and tools. Manual and survey-based analysis alone, without any focus on business policies and values, often ends in disaster for the modernization project. These migration decisions are used as input for the next stage, where the readiness of these decisions is evaluated. For example, for application migration with the Re-Platform migration pattern, one of the migration decisions is to modernize the application and migrate it to a container platform...
