4. Multiple Physical Replicas
9/29/ :45 AM
SQL Azure Database
Single Logical
Database
Multiple Physical Replicas
Replica 1
Single Primary
Based on SQL Server 2008 R2 engine
Use same tools and data access frameworks
Six global datacenters
High Availability & Redundancy
Reads are completed at the primary
Writes are replicated to a quorum of secondaries
Replica 2 DB
Slide Objective Use this slide to transition into an explanation of SQL Azure Database (Reporting and Data Sync will be covered later)
Explain at a high level how SQL Azure works
Speaker Notes
Design Principle of SQL Azure: Focus on combining the best features of SQL Server running at scale with low friction
SQL Azure is a high availability database
Always three transaction consistent replicas of the database
One primary replica; two slave replicas
Failure of a replica will result in another replica being spun up immediately by the fabric
Failure of the primary replica means a slave replica will become the primary and a new slave will spin up
Minimal down time
Typically just a few dropped connections
Easy to code for the failover scenario- if you are ding god connection management and error handling will be fine
Clustered index required on all tables to allow replication
Notes
Useful article from SQL Azure team
Replica 3
Multiple
Secondaries

10. On-Premises to Cloud Symmetry
SQL Server to SQL Azure Sync
SQL Azure
Benefits
Makes cloud extension rather than replacement
Enables moving workload to cloud in stages preserving investment in existing infrastructure
New scenarios spanning enterprise, cloud
Sync

11. SQL Azure to SQL Azure Synchronization
Benefits
Geo-synchronization of data across data centers
Scale-out read or read/write

12. 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

14. Data Tier Applications
Data-Tier Application Project
(Departmental apps in V1)
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
Visual Studio
Build
.dacpac
SQL Azure
Deploy

15. Software Requirements
So what are the requirements for this? It is part of Visual Studio 2010 functionality. Additionally, to deploy data-tier applications, you need to running SQL 2008 R2 (enterprise

16. What’s in a DACPAC?
This is a view of an expanded DACPAC—as you can see it consists of 3 SQL scripts—the main schema script and any pre and post deployment scripts. There are a couple of XML files that define the physical and logical models around the data. As vendors begin to use this technology as method to roll out databases for their technology, as DBAs this will be the place where we can preview their schema and identify any potential issues. Also, not that you would do this, but always review code in a dacpac you downloaded from an unknown source, to ensure that there isn’t any malicious code. In Visual Studio Premium and higher, you can compare two DACPAC schema files, or just use a file comparison tool.
