This is the last chapter and we have finished our journey with Azure Functions.

We started our journey with a discussion of serverless architecture with the evolution of cloud computing and we discussed in detail IaaS and PaaS.

After that we discussed Azure Functions and looked at the differences between Web App AWS Lambda and Azure Functions. We created our first function that processed a photograph and created a thumbnail. We discussed the architecture of a trigger and different types of triggers available in Azure.

In the middle of our journey, we learned about binding with the Azure Function and Webhook. After that we created a real-life example of an Azure Function and we configured Continuous Integration using the Build definition and Continuous Delivery using the Release definition.

At the end of our journey, we covered how to monitor a Functions App using the available monitoring in the Function App itself.

In this chapter we looked at other languages for writing code in Azure Function. We briefly introduced the Python and PHP Azure Function. We created the Azure Function in Python and installed the third-party module using Kudu editor. We also learned how to use that module in Python code. We created a Python HTTP API and tested it. In the following section of this chapter we created a PHP Azure Function and got some idea of PHP code and ran that code.
