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 to build a resilient platform

This section will design a solution for the application platform on IBM Cloud. BC refers to the capabilities of any mission-critical workload in that it can never go down or be unavailable for any reason. In addition, there are some other expectations, as follows:

  • The business will not be hampered due to the unavailability of systems.
  • End users will receive immediate responses at all times.
  • For end users, the failure will not be visible. In the case of any system being unavailable, it will be possible to respond to the end user seamlessly by using alternative systems.
  • For mission-critical workloads for the end user, there will be zero downtime. We can define a mission-critical workload as one where the application, database, or web server meets at least one of the following criteria:
    • HA architecture such as clustering and hot standby.
    • 24/7 support and callouts for both phase 1 (P1) and phase 2 (P2) problems.
    • Support prioritized...
