DevTest 01: Why Dev and Test with Microsoft Azure

Learn how to use Azure Redis Cache to store and retrieve data in a way that is more fast and more simple.
Very nicely explained.
I am a ASP.NET developer and new to Azure. I had implemented cache techniques in my ASP.NET projects. But azure is totally new for me.
Could you please share some scenarios where Redis Cache can be implemented? Also do let me know how is it different from cache techniques available in ASP.NET (onprem)?
