Migrate SQL Server Apps to SQL Azure Cloud DB

Mark Kromer, MicrosoftJoe D’Antoni, Synthes

Session Objectives and Takeaways

Objectives:Overview of SQL Azure Cloud DBMigrate application databases to AzureDemonstrate database migration from SQL Server to CloudApplication Database Deployment with Data-Tier Application

SQL Azure DatabaseThe first and only true relational database as a service

Elastic Scale Developer Agility

Self-managed

• Database utility; pay as you grow

• Flexible load balancing• Business-ready SLAs• Enable multi-tenant

solutions• World-wide presence

• Easy provisioning and deployment

• Auto high-availability and fault tolerance

• Self-maintaining infrastructure; self-healing

• No need for server or VM administration

• Build cloud-based database solutions on consistent relational model

• Leverage existing skills through existing ecosystem of developer and management tools

• Explore new data application patterns

SQL Azure Database

On-Premises to Cloud Symmetry

SQL Server to SQL Azure Sync

Sync

Benefits• Makes cloud extension

rather than replacement

• Enables moving workload to cloud in stages preserving investment in existing infrastructure

• New scenarios spanning enterprise, cloud

SQL Azure

SQL Azure to SQL Azure Synchronization

Benefits• Geo-

synchronization of data across data centers

• Scale-out read or read/write

Extending Data to Retail and Remote Offices

SQL Azure to SQL Server Sync

Benefits• Share data with remote and

retail offices, bringing data closer to the end-users

• Lower latency – data access doesn’t require round trips

• Higher availability – app still runs if server is unreachable

• Reduced network utilization – most data access is local

Data Tier Applications

New feature in SQL Server 2008 R2 Allows developers to own the database

schema and definitions Still needs work (more to come) Microsoft seems to have invested

deeply to build this, so it will get better (hopefully)

Interacts with SQL Azure—this is one method of deploying application code there
