CCE and Cloud Computing-In Microsoft BPOS since 2008- Portal- Outlook- OCS-Azure- Internet Ordering- Opportunity with other applications are being explored- Data in the cloud
Internet Ordering: Options Explored Host in CCE data center- reuse of existing application, Heavy invest ininfrastructure Build a complete solution on the cloud- use infrastructure in the cloud but heavy softwareinvestment Using SAS type of solution- a product off the shelve and retrofit. . How about a combination of allthree .

SOA: Powers our Application
SOA is not Just webServiceService Catalog:What Services exist?We need to know if a Service already exists and how to use it.Governance:What qualifies as Service?Understand where Services are being used.Performance and Service Level Management:Monitor if Services are working and raise necessary alerts when required.Measure how often Services are being used.Forecast demand & allocate resources to high-priority requestsSecurity and Identity Management:Who can access Services?Centralized Security from one place.Versioning and Risk Management:How do we manage changes for Services?What will be the impact of changing a Service?

Legacy to Cloud
Conclusion There is not one way to design a cloud based application. Cloud is not replacing SOA its complementing it. Same organization may have multiple form of cloud model. Leverage what you have today when you build a cloud based application. Cloud adds an option to our infrastructure, it does not replace existingplatform. Don’t forget Security and standards. Its still evolving. Your can mix and match technology when building a cloud application.
