Cloud Native Development Patterns and Best Practices

By: John Gilbert

Overview of this book

Build systems that leverage the benefits of the cloud and applications faster than ever before with cloud-native development. This book focuses on architectural patterns for building highly scalable cloud-native systems. You will learn how the combination of cloud, reactive principles, devops, and automation enable teams to continuously deliver innovation with confidence. Begin by learning the core concepts that make these systems unique. You will explore foundational patterns that turn your database inside out to achieve massive scalability with cloud-native databases. You will also learn how to continuously deliver production code with confidence by shifting deployment and testing all the way to the left and implementing continuous observability in production. There's more—you will also learn how to strangle your monolith and design an evolving cloud-native system. By the end of the book, you will have the ability to create modern cloud-native systems.

Observability

The classic statement, “it works great in my environment”, represents a lack of observability. Traditionally, operations and development teams have used different tools to observe the behavior of their systems. Operations have historically been largely limited to black-box monitoring. Ops could monitor the operating system, processes, memory, CPU, disk I/O, network I/O, some log files, and the database, but they had little visibility into the inner workings of the applications. When a system underperformed, the Ops team could confirm the fact that is was underperforming, but could not necessarily state why it was underperforming.

Eventually, the development team was brought in to investigate the problem in a lower environment, where they can use profilers and debuggers to perform white-box testing and potentially diagnose the problem and propose a solution...
