No man is an island, “No man is an island”
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, John Donne
It tolls for thee. (1572-1631)

29. 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
37. 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

41. • 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
