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.

Client-Side Metrics with Azure Application Insights


You can also integrate Application Insights with client-side applications. There are SDKs available for iOS, Android, React Native, Xamarin, and vanilla JavaScript. This is a much more useful place for metrics in a serverless architecture. Client applications are very likely to be running on machines with very limited resources, such as old mobile phones. It's also useful to record your user flows. This is the journey your users take through your application from page to page. This can be useful for optimizing sales funnels.

A good example of this is Android applications, which run on a very fragmented ecosystem with varied support. It's quite common to have pervasive skins from manufacturers that modify how applications interact with the screen and the user in general. Say you are producing a game application for Android. There's a lot of things that can go wrong with that, and Application Insights will allow you to view live streams of...
