In this chapter, you've seen how to choose the best plan for serverless services that could also be used as PaaS services. You now know about Azure Functions and its best practices. You also saw which use cases are better suited to be implemented with a serverless approach, including IoT, backend apps (mobile, single-page web apps, or Alexa skills), and integrating different SaaS services.

Since this is the last chapter of the book, we hope that you've enjoyed reading it and found it useful. Happy coding in the serverless world!
