In this chapter, you learnt the basics of cloud computing, and how Microsoft Azure plays a role in providing IaaS, PaaS, and SaaS models. We primarily focused on Azure App Services, and explored ways to develop and deploy a .NET application on Azure. Scalability is an essential key, and you learnt how easy it is to scale out or scale up our applications running on Azure by using different techniques to increase the performance of our application. Last, but not least, we discussed the logging and monitoring options in Azure, and saw how we can use Application Insights with web applications running on the cloud to monitor application request/response times and other metrics. The next chapter is all about security, where you will learn about the different security models available to secure the .NET Core applications.
