Serverless computing enables developers to build applications faster by eliminating the need for them to manage infrastructure.
Cloud providers have brought a revolution in the cloud market by introducing serverless computing services over the internet. Many top cloud providers such as Amazon Web services, Microsoft Azure, and Google Cloud Platform have launched serverless computing. Often the term serverless computing is misunderstood with a type of computing without servers. In actuality, servers run in the background to handle all operations, but cloud providers are responsible for managing, scaling up or down, and maintaining those servers.
We can write our code directly to the portal or can set up continuous integration and deploy our code through Azure DevOps, GitHub, or any other supported development tools.
We can protect HTTP-triggered function with OAuth providers, such as Azure AD, Microsoft account, or other third-party accounts, such as Google, Facebook, and Twitter
It allows us to write a function in the language of our choice, such as C#, F#, Java, PHP, JavaScript, etc. You can check the list of supported languages
Azure Functions allow us to download code dependencies from NuGet and NPM, so we can use libraries that need to execute our code and are available on either NuGet or NPM.
Azure provides a flexible consumption plan as per our requirement. Also, if we already use App service for our other application, we can run the function on the same plan. So, there is no additional cost we need to pay.
The function runtime is open source.
