Solutions Architect's Handbook

By: Saurabh Shrivastava, Neelanjali Srivastav

Overview of this book

Becoming a solutions architect gives you the flexibility to work with cutting-edge technologies and define product strategies. This handbook takes you through the essential concepts, design principles and patterns, architectural considerations, and all the latest technology that you need to know to become a successful solutions architect. This book starts with a quick introduction to the fundamentals of solution architecture design principles and attributes that will assist you in understanding how solution architecture benefits software projects across enterprises. You'll learn what a cloud migration and application modernization framework looks like, and will use microservices, event-driven, cache-based, and serverless patterns to design robust architectures. You'll then explore the main pillars of architecture design, including performance, scalability, cost optimization, security, operational excellence, and DevOps. Additionally, you'll also learn advanced concepts relating to big data, machine learning, and the Internet of Things (IoT). Finally, you'll get to grips with the documentation of architecture design and the soft skills that are necessary to become a better solutions architect. By the end of this book, you'll have learned techniques to create an efficient architecture design that meets your business requirements.

Live migration cutover

The following diagram illustrates a cutover strategy for live zero-downtime migration. In this method, the data is continuously replicated to the destination, and you perform most of the functional validation and integration testing at the destination while the application is still up and running:

Live migration cutover using blue-green deployment

In the replication process, the source on-premise database and target cloud database are always in sync. When all the integration and validation tests are completed successfully and the application is ready for cutover, you can take a blue-green approach to do the cutover. You will learn more about blue-green deployments in Chapter 12, DevOps and Solution Architecture Framework.

Initially, the application continues to run both on-premises and in the cloud, resulting in traffic being distributed between the two sides. You can increase traffic to cloud applications gradually until all the traffic is directed to the new...
