Presentation

Cloud Computing Landscape

This session will focus on the importance of standards for prioritized support of functionality of Clouds and interaction between Clouds - integration, interoperability and portability.

Customers expect the Cloud Services they use to be as open as the rest of their IT environment, consistent with their Enterprise Architecture approach. Cloud Computing also requires us to think of (IT) services at multiple levels ­ with the highest levels requiring strong Enterprise Architecture skills ­ ultimately the alignment of technology and organizational objectives.

There is trend to industrialize the delivery and support of IT services to be more repeatable, reusable, flexible and scalable elements. It is important to understand how the enterprise architect will incorporate and use Cloud Services in conjunction with the traditional IT environment. The enterprise architect will need to deal with Cloud Services which range from elemental to transaction to business services to more elaborate services involving human interaction. Typically, such services are thought to fall into three main categories: infrastructure, platform, and software, “as a  service.”  Different Cloud deployment models, such as on-premise, off- premise or a federation of these, can also be supported.

By understanding the main actors and their interaction models in the use and delivery of Cloud Services, and the Cloud deployment models, it is possible to identify the Architectural Model for Cloud Computing supporting both existing and evolving capability. In order to realize the maximum value of the Cloud, the services need to be flexible, separating the concerns between those who use the services and those who provide them, while supporting optimization strategies such as flexible sourcing to achieve economies of scale. Standards will therefore play a critical role in how Clouds operate and interoperate to deliver higher-level business value.

Referencing examples, this session will present a view of the importance of standards for prioritized support of functionality of Clouds and interaction between Clouds - integration, interoperability and portability.
