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.

Introduction


In the previous chapter, you used services to ensure the security of your serverless architecture. You used an API Management instance to protect your serverless functions from denial-of-service attacks, and you used Azure Active Directory B2C to protect your clients' private data (stored in its login process).

When you have created a complex and sophisticated serverless architecture, it's incredibly important that you're able to maintain it and recover it from failures. Luckily, large classes of failures, such as memory leaks and insufficient resources, should be absent because serverless services autoscale resources, but other errors, such as network failures and security breaches, can still happen. The only way you can fix these failures is by understanding what failures have occurred, and the only way you can do that is with some form of observability.

In this chapter, you will learn about observability and how to use Azure Application Insights to help you collect and analyze...
