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 ResourceFactory • The benefits of wrapping cloud services under an IT controllers • Centralization and standardization of policy • Auditability for compliance • Measurement & monitoring usage and payments 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
