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.

Implementing Disaster Recovery as a Service (DRaaS)

A disaster can be explained as any disruption to the standard or regular business of any components in the platform. To reduce loss, a mission-critical production environment must be protected against such disruptions. Mission-critical production environments need BC, and therefore they need to be recoverable from any failures. DR ensures that systems are fault-tolerant and can recover from any failures. In this section, we will understand the concepts of Disaster Recovery as a Service (DRaaS). The IBM ITBC127 standard defines a disaster as a sudden, unplanned calamitous event causing significant damage or loss. Some other characteristics of disasters are presented here:

  • Any event that creates an inability on an organization’s part to provide critical business functions for some unscheduled period.
  • In the business environment, any event that creates an inability on an organization’s part to provide critical...
