Discovery• The ability to publish a service’s endpoint

metadata and discover services using well defined criteria

• Design time– Find available services

• Runtime– Reduced Config– Location agility – Dynamic / self healing apps

• 2 Modes – adhoc and managed proxy service• WS-Discovery – Standard interoperable discovery

protocol

Dallas

• “Data as a Service” • Built on Windows Azure & SQL Azure• Discover Public Data Sources, Explore them &

Use them• Aim is to encourage greater innovation & apps

to be created rapidly• http://www.sqlazureservices.com/

Power Pivot

• Formerly known as Project “Gemini”• Data Analysis add-in that delivers unmatched

computational power within Excel 2010• http://www.powerpivot.com/

Pivot

• Live Labs latest experiment – available to trial by invitation

• Pivot is an interaction model for viewing data collections

• Pivot makes it easier to interact with massive amounts of data in ways that are powerful, informative, and fun

Persistence

Persistence

• Storing WF Application State• Ensures that durable Workflows can be

recovered and processing resumed• Scenarios– Reliability - Long running workflows– Availability - Recovery when application or machine

crashes– Scalability - A workflow unloads idle instances from

memory; the retry loading of locked instances

Summary• Workflow is ideally suited for business services• Workflow services handle complex coordination– Composition of services– Message correlation to instances

• The Windows Server AppFabric supports WCF and Workflow services by– Providing runtime databases– Capabilities for monitoring, persistence, hosting and caching– Tooling and scripting to manage and monitor WCF and WF
