Data Sync

Database Reporting

• SQL Azure provides logical SQL Server• Gateway server that understands TDS protocol

• Reporting Services in CTP, launch soon• Based on SQL Server Reporting Services 2008 R2

• SQL Azure Data Sync Powers movement of data• Cloud cloud, On-premises cloud

SQL Azure Database

Use same tools, data access frameworks, T-SQL based language

SQL Azure Reporting CTPFeatures:

Based on SQL Server Reporting Serviceso Interactive and tabular reportingo Data visualizations: charts, graphs,

mapping, gauges

SQL Azure Database data sources

Utilizes BI Developer Studio (free) to author reports

Export to Excel, PDF, CSV formats

Core scenarios:Operational reporting on SQL Azure data

Embed reports into Windows Azure or on-premises applications

Reporting

SQL Azure Data Sync CTPSync Data From On-Premises to Cloudo Span data from enterprise to cloud

o Build offline cached experiences

o Sync with branch offices and mobile devices

Sync Between SQL Azure Databaseso Geo-Replication, Read/Write Scale out

No-code Synchronization of Datao Easily define data to be synchronized with

out coding

o Choose how often data is synchronized

o Handle issues where same data is changed in multiple locations

o Administration capabilities for tracking data and monitoring potential issues

Windows Azure AppFabricBuilding Block Services for developing connected applications

CachingService Bus

Access Control

• Service bus provides relay service• Enables cloud apps to integrate with on-premises services

• Use Access Control Service to externalize security code• Claims-based, federated authentication & authorization

• AppFabric Caching• Distributed in-memory cache for Windows Azure apps

Why Care?

Operational Excellence & Elasticity• Need high reliability

• LOB, software as a service• Need massive scale

• Social networking, web 2.0• Have variable load /

unpredictable lifetime• Ticketing, marketing

• Parallel processing• Financial applications

• Don’t fit in well with a company’s data center• Avoid IT dept, support joint

ventures• Benefit from external storage

• Archive
