As of ArcGIS Desktop version 10.1, you can publish any spatial data as a live online map service accessible and even editable by anyone with a web browser, without the need to own and maintain ArcGIS Server. Prequisites for cloud publishing grants are a demonstrated proficiency in ArcGIS Desktop map creation and catrographic design and the submission of some example map snapshots (100dpi jpg, <1mb please) with your application. All cloud grants are annual only, you will have to renew them each year, and in your renewal application provide a summary of maps you have created and how you have shared them. You can publish to either of 2 cloud GIS environments that esri supports: Amazon and ArcGIS Online. You'll need to exhibit a basic understanding of the cloud publishing process as part of your application, as detailed here: -ArcGIS 10.1 for Server-Approaches for publishing services with ArcGIS.

For more details on how to stretch your credits see GUIDELINES FOR MANAGING AGOL SUBSCRIPTION CREDITS
3. Amazon Cloud instances with ArcGIS Server latest version, shared account: Eligiblity requires you to demonstrate a working knowledge of ArcGIS Server in your application essay. If you have none, you can apply for esri ArcGIS Server Training in the same application form and once you complete that course you can start using the cloud account. This is a shared amazon account. The resource is called an ArcGIS Server on Amazon EC2 , set up on Windows Server 2008 enterprise edition, You will prepare your map services for publishing on your desktop then publish directly to the cloud with ArcGIS 10.1. There will be up to 20 other users and publishers on that same amazon cloud machine, so some limits will apply in sharing that common resource. This platform can solve some of the AGOL credits limitations for cacheing services and hosting feature access but you'll have to do more coordination and scheduling with other users. This grant option may not be suitable for those who have dozens of services to publish or very large complex services.
