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 incident management

Incident management can be described as restoring the healthy state of a system after an incident affects that system. IBM Architecture Center describes the end-to-end workflow for managing any incident in the reference architecture, as shown in Figure 10.13.

Incident management happens in four stages: monitoring, analyzing, planning, and executing. The primary artifacts for incident management are observability dashboards and runbooks.

The following dashboard shows a typical cloud platform’s current IT and business aspects. In addition, it shows the healthy and unhealthy components of the platform and provides visual insights to determine the incident along with its root cause:

Runbooks refer to scripts or written instructions that are used by first responders to resolve...
