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. By the end of this handbook, you'll have learned the techniques needed to create efficient architecture designs that meet your business requirements.

Understanding the circuit breaker pattern

It's common for a distributed system to make a call to other downstream services, and the call could fail or hang without response. You will often see code that retries the failed call several times. The problem with a remote service is that it could take minutes or even hours to correct, and an immediate retry might end up in another failure. As a result, end users wait longer to get an error response while your code retries several times. This retry function would consume the threads, and it could potentially induce a cascading failure.

The circuit breaker pattern is about understanding the health of downstream dependencies. It detects when those dependencies are unhealthy and implements logic to gracefully fail requests until it detects that they are healthy again. The circuit breaker can be implemented using a persistence layer to monitor healthy and unhealthy requests over the past request interval.

If a defined percentage...
