What are some of the concerns you might have working with AWS?

You have founded an emerging successful e-commerce platform (toysforkids.com) that sells unique artisan toys and child-related products. Your current on-premise environment needs to grow to get you to your next level of expansion. The project has been internally sold by the CIO as a cost-saving initiative, along with the elasticity Cloud computing provides for the company. You have sent out a Request for Proposal (RFP) to Cloud Services providers, and you have narrowed your choices to Amazon Web Services (AWS) and Microsoft (MSFT) Azure. Your current environment is Microsoft-centric (Windows 10, Windows Servers, MS-SQL-Server, and other MSFT products). Proposal responses are back. AWS appears to be the most cost-beneficial.

Please discuss the following:

What are some of the concerns you might have working with AWS? How might those concerns be allayed?

Are there any other choices you might consider?
