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 HA

HA is a capability of a cloud solution that enables the solution to perform well as the number of access requests increases. To design a highly available solution, the organization must determine the characteristics of their HA requirement, which is crucial for any cloud solution. This section discusses the benefits of HA, steps for planning and understanding the requirement for a HA design for a platform, and steps for designing HA.

Benefits of HA

HA is a crucial characteristic of any platform to achieve resiliency. Most of the time, applications, data, and services deployed on the target platform should be available to end users. HA is designed by making a redundant copy of the system, data, and applications. The main benefits of HA are listed here:

  • HA ensures that systems can be taken offline for planned maintenance and unplanned outages while their corresponding mirror system continues to work. For example, in the Landorous use case, the organization...
