What is Cloud Computing?

Cloud computing is the use of computing resources that are delivered as a service over

a network

SQL Server vs. Windows Azure SQL Database Feature SQL Server Windows Azure SQL Database

Data Storage No size limits as such Currently supports a database of up to 150 GB of data, in increments of 10 GB.

Authentication • SQL Server Authentication• Windows Authentication

• SQL Server Authentication

Schema No such limitation Does not support heaps. All tables must have a clustered index before data can be inserted.

TSQL Supportability

No such limitation Certain Transact-SQL commands are fully supported; some are partially supported while others are unsupported.

SQL Agent

Supported Cannot run SQL agent or jobs on SQL Database.

SSIS Supported SSIS service not available on Azure platform.

The Big 3

Is it secure?

What about performance?

What does it cost?

Is it secure?

Layer DefencesUser • Account management, training and awareness, screening

• Open and interoperable access control service

Data • Strong storage keys for access control• SSL support for data transfers between all parties

Application • Front-end .NET framework code running under partial trust• Windows account with the lowest level of privileges

Host • Stripped-down version of Windows Server 2008 R2• Host boundaries enforced by external hypervisor

Network • Host firewall limiting traffic to VMs• VLANs and packet filters in routers

Physical • World-class physical security provided by GFS• ISO 27001, SSAE 16, FISMA Moderate, and more

What about performance?

Understand app performance constraintsBenchmark on different VM sizes (Set-AzureVMSize)Use SQLIOTraditional performance troubleshooting & Azure Storage Analytics

Use default max server

memoryMove data / log off OS diskDisable write caching for data on OS disk (Set-AzureOSDisk)Consider putting tempdb on non-persistent cache disk (D:\)Consider using database page compression to reduce I/O
