In my previous article , we saw detailed step on how to create a server-less function using Azure Function . If you are not familiar with Azure Function topic I highly recommend you to have a look before we proceed here. Alright, In this article will see how to create/configure OpenApi for our Crypto Function and to be able to use in other applications. Before proceeding there let us understand OpenApi protocol.

If you want to build a single endpoint which is capable of performing business and performance critical and high available process behind the scene and at the same time it should be accessible to all the ecosystem and development approach right from Mobile to REST calls and Cloud Apps "Azure Function" has it all. Microsoft Azure as evolved(ing) to give best it can from PaaS, IaaS and Azure Functions as FaaS(Function as a Service). The biggest advantage of using Azure Function is its server-less. So, no configuration and maintenance of infrastructure is needed. In this way we can only  pay for resource we consume, But still Azure provides you the ability to configure fixed service plan for better dedicated performance for your function. So i leave it up to you to choose the plan by considering not paying for un-utilized or under utilized server cost or consumption based plan.  Create Azure Functions using Visual Studio Install "Azure Functions" templa...
