Learning Azure Functions

By: Mitesh Soni, Manisha Yadav

Overview of this book

Functions help you easily run small pieces of code in cloud with Azure functions without worrying about a whole application or the infrastructure to run it. With Azure functions, you can use triggers to execute your code and bindings to simplify the input and output of your code. This book will start with the basics of Azure Functions. You will learn the steps to set up the environment and the tools that we will be using in the further chapters. Once you have a better understanding of this, we will be creating our first hello world function app. Later you will be introduced to triggers, how they are used to activate a function, and how binding can be used to output results of a function.You will also explore the steps to create an assembly with complex functionality that can be used by functions. Next, this book will teach you to scale your functions and use them to process data, integrate systems, and build simple APIs and microservices. Finally, this book will cover some diagnostic techniques with Azure App services and best practices of working with Azure Functions. By the end of this book, you will be well-versed with the techniques of scaling your Azure functions and making the most of serverless architecture.

Chapter 8. Business Considerations

"Do not wait; the time will never be 'just right.' Start where you stand, and work with whatever tools you may have at your command, and better tools will be found as you go along."

- George Herbert

Some considerations that most developers need to take into account when deciding to use functions as the solution are monitoring, pricing/hosting plans, and best practices.

Monitoring is one of the important aspects related to application life cycle management and we need to configure all the available configurations of monitoring in Azure.

Once we are ready with Azure Function Apps, it is very important for us to understand how to monitor the health of functions. Azure Functions have their own kind of monitoring, which are useful but basic.

For an advanced level of monitoring, we can utilize Application Insights. Another important business consideration is to understand the concepts of pricing so that we can make an informed decision based on the anticipated load...
