3. SQL Azure Database Sync Service Reporting
Extending SQL Server to the Cloud
Database
Sync Service
Reporting
SQL Azure Database
Familiar SQL Server relational database model
Support for existing APIs & tools
Built for the cloud with high availability & fault tolerance
Easily provision and manage databases across multiple datacenters
Data Sync Service (CTP)
Provides two-way sync of SQL Azure Databases across datacenters
Example service available in the SQL Azure Labs environment
SQL Azure Reporting (CTP)
Reporting Services running on the Windows Azure Platform

4. SQL Azure Database

5. SQL Azure database service
SQL Azure provides logical SQL Server
Looks like SQL Server to TDS Client
Actual data stored on multiple backend data nodes
Logical optimisations supported
Indexes, Query plans etc..
Physical optimisations not supported
File Groups, Partitions etc…
Transparently manages physical storage

6. Working with SQL Azure Databases
Your App
SQL Azure
TDS
Change Connection String
Primary SQL Azure database
Secondary database copies

7. Behind the Scenes of SQL Azure
Apps use standard SQL client libraries: ODBC, ADO.Net, PHP, …
Application
Internet
Load balancer forwards ‘sticky’ sessions to TDS protocol tier
TDS (tcp) LB
Security Boundary
TDS (tcp)
Gateway
Gateway: TDS protocol gateway, enforces AUTHN/AUTHZ policy; proxy to backend SQL

10. Database Editions 1 GB 5 GB 10GB, 20GB, 30GB, 40GB, 50GB Web Edition
Business Edition
This is the maximum size we will not let you grow beyond
You will only be charged for the actual peak size rounded up in any one day
For example, a 3.4 GB Web Edition will be charged 5GB rate.
CREATE DATABASE foo (EDITION=‘web’, MAXSIZE=1GB);
ALTER DATABASE foo MODIFY (EDITION=‘business', MAXSIZE=50GB);

11. Database Editions Subscription & Pay as you go pricing Web Edition:
1 £6.06/month (ie ~ £72 / year)
5 £30.28/month
Business Edition:
10 GB /20GB / 30GB /40GB / 50GB
@ £60.60 / 10GB / month
Data Transfer Cost
£0.06 / GB in and £0.09 / GB out
NO cost for intra-datacentre data transfer
Business Edition
Up to 50 GB
10 GB increments
Web Edition
1 GB or 5 GB

12. Demo

13. Few other things to consider
Latency
Connection throttling
Reasons include
Lock Consumption: Sessions using over 1million locks
Excessive Log usage: Single txn consuming >1Gb txn
Uncommitted Transactions: Single txn consuming > 20% of the log
Excessive Tempdb usage: Session using > 5Gb of TempDB …

14. “Backup” Database Copy (Available NOW!)
Copies asynchronously ie control returns before copy completes
View copy status: “Select * from sys.dm_database_copies”
DACPAC (see
SQL Azure Restore (CTP Soon)
Point in time database restore
CREATE DATABASE database_destination_name AS COPY OF [source_server_name.]database_source_name
DacImportExportCli.exe -s myserver.database.windows.net -d northwind -f C:\northwind.bacpac -x -u username -p password

24. Scaling Database Applications
Scale up
Buy large-enough server for the job
But big servers are expensive!
Try to load it as much as you can
But what if the load changes?
Provisioning for peaks is expensive!
Scale-out
Partition data and load across many servers
Small servers are cheap! Scale linearly
Bring computational resources of many to bear
Cluster of 100’s of little servers is very fast
Load spikes not as problematic
Load balancing across the entire cluster

25. SQL Azure Federations http://blogs.msdn.com/b/cbiyikoglu/
CREATE DATABASE SalesDB go
CREATE FEDERATION CustFed (cid BIGINT RANGE)
USE FEDERATION CustFed(cid=0) WITH FILTERING=OFF, RESET
CREATE TABLE Customer(
CustomerID bigint Primary Key,
…) FEDERATED ON (cid = CustomerID) Go
USE FEDERATION ROOT WITH RESET
ALTER FEDERATION CustFed SPLIT AT (cid = 100)
USE FEDERATION CustFed(cid=105) WITH FILTERING=ON, RESET
Select * from customer
Azure DB with Federation Root
Federation Directory, Federation Users, Federation Scheme, …
Federation “CustFed”
(Federation Key: CustomerID)
Member: PK [min, 100)
AU PK=5
AU PK=25
AU PK=35
Member: PK [100, 488)
