Peer-to-Peer Replication

Query Notifications

Scale-Out Analysis Services

Scalable Shared Databases

Read-only database in SAN

Mounted by multiple reporting servers

Applications access a consistent copy from any server

Distributed Partitioned Views

Data is partitioned horizontally across multiple servers

Transact-SQL view retrieves all data with a UNION ALL clause

Requests can be directed by using data dependent routing

Peer-to-Peer Replication

Data is replicated to local servers

Local modifications are propagated throughout the enterprise

Query Notifications

Application notified when queried data changes

Optimal cache refresh behavior

Scale-Out Analysis Services

Centralized, read-only Analysis Services database shared by multiple instances

Client applications connect to a single virtual IP address
