An overview of Azure Integration Services | Azure Friday 

Great Explanation even years later, thank you.

Great walk-through of the technology stack in Azure Integration Services

I'm using Azure integration account(AIA) , that work on fixed price model (per hour). So if for some time there is no use of AIA so what i can do for reducing unnecessary cost.

The subtitles say iPads, the term the guys is saying is iPaaS - Integration Platform as a Service, not sure Microsoft will be using Apple's IPads :)

Thank you
