Taking a look at the Azure Table Storage REST API

Originally, if you wanted to access Azure functions from your own applications, you had to use an C# client library. Today, there are HTTP REST APIs for almost anything, thus making it very easy to access Azure from almost any programming environment.

Table Storage is one of the basic services in Azure for storing (tabular) data, and it too has a nice REST API. You can do all basic CRUD operations for table objects – called entities – but you can also manipulate access control lists (ACLs), for preflight checks, and read table properties.

Remember that the Azure REST API is subject to Cross-Origin Resource Sharing (CORS) rules as any other HTTP/REST API, if called from the context of a web browser application. If done from the backend, there usually aren't similar enforced rules.
