DESCRIPTION

The road to Cloud Computing is not without a few bumps. This session will help to smooth out your journey by tackling some of the potential complications. We'll examine whether standardization is a prerequisite for the Cloud. We'll look at why refactoring isn't just for application code. We'll check out deployable entities and their simplification via higher levels of abstraction. And we'll close out the session with a look at engineered systems and modular clouds.

Agenda

Key considerations to Cloud implementation? Consider….

• What forces drive your adoption of Cloud?

• What sort of architecture do you need?

• What sort of architecture do you need?

• The focus of component architectures?

• What are the ‘Deployable Entities’?

• How will you ‘refactor’ the organization?

What Forces influence your Cloud Adoption?

- Consider three differentiating criteria

- This perspective drives your decisions

Business Model IT as Support vs. IT as a Business

Is your cloud project ‘cutting costs’ or ‘driving business’?
