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


Security in serverless is solved in the same way as all other problems in serverless: by using a managed service that someone else has built and solved all of the problems with. This doesn't solve issues that are created by the developer, though, such as SQL injection exposure and a large attack surface, but it does solve a lot of issues. In this chapter, you've learned how to protect your serverless functions with an API management instance and how to use Azure Active Directory B2C to both protect your customers' data and speed up your development.

Now that you have created a simple security layer using managed cloud services, the next chapter will focus on fulfilling another basic requirement of all applications with managed services—observability. You will also learn about the unique challenges Serverless presents and why good observability practices are vital.
