Advanced Serverless Architectures with Microsoft Azure

By: Daniel Bass

Overview of this book

Advanced Serverless Architectures with Microsoft Azure redefines your experience of designing serverless systems. It shows you how to tackle challenges of varying levels, not just the straightforward ones. You'll be learning how to deliver features quickly by building systems, which retain the scalability and benefits of serverless. You'll begin your journey by learning how to build a simple, completely serverless application. Then, you'll build a highly scalable solution using a queue, load messages onto the queue, and read them asynchronously. To boost your knowledge further, the book also features durable functions and ways to use them to solve errors in a complex system. You'll then learn about security by building a security solution from serverless components. Next, you’ll gain an understanding of observability and ways to leverage application insights to bring you performance benefits. As you approach the concluding chapters, you’ll explore chaos engineering and the benefits of resilience, by actively switching off a few of the functions within a complex system, submitting a request, and observing the resulting behavior. By the end of this book, you will have developed the skills you need to build and maintain increasingly complex systems that match evolving platform requirements.

Summary


Implementing effective observability is incredibly easy in this age of cloud services. Services such as Application Insights automatically start taking most metrics and basic logs, even implementing tracing with correlation IDs (a fairly complex and high-maintenance job to do yourself, as you have to make sure you forward on the correlation ID to every service). It's also absolutely vital for complex distributed systems where errors can be difficult to isolate, which is usually the case with serverless architectures.

In this chapter, you have integrated Application Insights into an Azure Function. You've written structured logs, integrated Application Insights with a client-side application, and used your skills to locate an error with a serverless function. In the next chapter, you will learn what chaos engineering is, and how to apply it to serverless systems.
