Overview of this book

Becoming a solutions architect requires a hands-on approach, and this edition of the Solutions Architect's Handbook brings exactly that. This handbook will teach you how to create robust, scalable, and fault-tolerant solutions and next-generation architecture designs in a cloud environment. It will also help you build effective product strategies for your business and implement them from start to finish. This new edition features additional chapters on disruptive technologies, such as Internet of Things (IoT), quantum computing, data engineering, and machine learning. It also includes updated discussions on cloud-native architecture, blockchain data storage, and mainframe modernization with public cloud. The Solutions Architect's Handbook provides an understanding of solution architecture and how it fits into an agile enterprise environment. It will take you through the journey of solution architecture design by providing detailed knowledge of design pillars, advanced design patterns, anti-patterns, and the cloud-native aspects of modern software design.

Mainframe migration with the public cloud

Many enterprises are moving their mainframe workloads to the cloud to take advantage of factors such as cost reduction, increased agility, technical debt reduction, digital strategy support, the legacy mainframe skills gap, and data analytics. Mainframe workloads are more challenging to migrate than x86-based workloads because legacy mainframe applications are often developed and deployed in a tightly coupled manner. For example, a mainframe application might include programs that are used by a number of subsystems or are directly called by other applications. In these cases, changes made to the underlying programs also affect the associated subsystems and applications.

For legacy applications, you need to take an incremental approach, where the migration is planned in waves, as a best practice. This approach helps to reduce risks because you select and prioritize closely related applications to be migrated together. However, this approach...
