An Enterprise’s View Public/Community Cloud SaaS PaaSIaaS Private Cloud AWS Google Nirvanix Rackspace VMM, Array, ViNe SASU E2C

Kind of deployment IaaS –Resource request and upgrade rights –Payment and decommissioning responsibilities PaaS –Application deployment and configuration rights pass up –Application lifecycle and EOL responsibilities SaaS –Browser standards –Authentication pass through?

E2C: How to think The benefits of wrapping cloud services under an IT controllers –Centralization and standardization of policy –Auditability for compliance –Measurement & monitoring usage and payments Resource Factory configuration resource actions

E2C essential capabilities Open client Federated identity Location awareness Security Metering & monitoring Management & governance Common file format for virtual machine images Common APIs for cloud storage, data & app federation Common APIs for expressing SLAs and lifecycle management

E2C use cases Using cloud computing resources as seasonal or peak overflow capacity Using cloud apps on a lease model Using cheaper ad lower TCO cloud storage to back up seldom used data Using cloud databases for online data maintenance

IT bypass? Application running in the cloud used by business employees and customers (through the business) Application running in the cloud and used by the customers Identity Security SLAs  Usage, Experience, Data Identity Federation Location awareness, data rules Meter & monitor SLAs  chargeback, cost control, usage

IT to IT Think supply chain integration Think about global relief efforts or other coalitions IT outsourcing and insourcing Are there standards of cloud interoperability? –What capabilities would you look for in such a standard? –Why? Transactions and currency
