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.

Understanding the IBM reference architecture for problem management

The IBM problem management reference architecture focuses on the activity and artifacts required for problem management, where the root cause of any incident is identified and resolved. The incident management system triggers problem management. The activities for problem management are mainly completed in three stages: RCA, corrective action identification, and mitigation. There are different well-known processes for RCA, such as the following:

  • Fishbone diagrams
  • Keppner-Tregoe
  • 5 whys

Fishbone diagrams

The incident is represented as the fish head, as shown in Figure 10.14. Each potential cause and method category is represented as a corresponding branch from the central arrow in a fishbone diagram. These causes are identified by asking the question Why does this happen? for each effect:
