no application
is an island
John Donne
(1572-1631)
“No man is an island” No man is an island, Entire of itself. Each is a piece of the continent, A part of the main. If a clod be washed away by the sea, Europe is the less. As well as if a promontory were. As well as if a manor of thine own Or of thine friend's were. Each man's death diminishes me, For I am involved in mankind. Therefore, send not to know For whom the bell tolls, It tolls for thee.
Bring entire application and all dependencies
Bring portion of application to the cloud while some resources stay on-premises
Latency? Security? “Chattiness”?
scenario to avoid(most of the times)
Two-way sync
One-way sync to cloud One-way sync from cloud
safer solution
Disaster Recovery Consolidation scenarios
Using the cloud for internet and mobile availability
Windows Azure Virtual Network
Hybrid Public/Private Cloud Enterprise app in Windows Azure requiring connectivity to on-premise resources
Manage identity and access control with on-premise resources (on-premises Active Directory)
Remote monitoring and trouble-shooting of resources running in Windows Azure
Cloud deployments requiring persistent IP addresses and direct connectivity across services
common scenarios
Branch A Branch B Multiple office/branch locations Share data between locations Aggregate data in the cloud
Branch A Geographic located applications - Use with Azure Traffic Manager Disaster Recovery
Scaling out the application Separating workloads, Reporting, Analytics
migrating...
Connect Cloud Apps via VIPs • Easily compose services by connecting public endpoints
• For advanced connectivity scenarios such as Active Directory or DCOM
• Simple, secure and highly efficient method of using IaaS and PaaS side-by-side
• Do not use write caching
• Avoid using OS drive for large databases
• Consider putting database and transaction log files on separate drives
• Consider putting tempdb on the non-persistent cache disk (D:\)
• Consider using database page compression to reduce I/O
• Consider latency between primary and replica when choosing sync mode

• See “Windows Azure Accelerator for Web Roles”
• Size (actual max:150Gb) – SQL Azure Federations
• All tables require clustered indexes – solution: refactor
• No Full-Text Search – Use FAST or Lucene.net or do-it yourself
• No Cross Database Joins available (or Linked Servers) – Use schemas, refactor
• No SQL-CLR – Refactor, please
• Performance SQL Azure info: http://msdn.microsoft.com/en-us/library/ee336279.aspx

Many Applications could benefit from migrating to a mixed deployment. Migrating to web/worker roles or taking advantage of other Windows Azure services (storage, cache etc..)
Simplified Deployment and Configuration Health Model Easy High Availability Instance Scalability OS Patching Automatic Firewall Configuration Simple Certificate Deployment Many others
Use Virtual Machines and VNET for Forklift Migration
