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.

Exploring the platform engineering service

A cloud platform can be divided into the physical platform layers and the cloud platform layers, where all the IaaS and PaaS products are deployed; the middleware layer, where middleware and SaaS solutions are deployed; and finally, the application layer. Each managed service, such as PaaS or IaaS, provided by a cloud provider has its own responsibility matrix, which defines the roles and responsibilities of service providers and organizations. Figure 10.2 shows the shared responsibilities for IaaS product management between IBM and customers. Therefore, in addition to the service management by the service or cloud provider, organizations should also establish the processes, practices, toolchains, and governance for the service management of different services deployed on the cloud. Usually, the cloud provider manages the physical layers and hypervisor layer.

On the other hand, organizations have some responsibilities for virtual components...
