Performance tuning
You can use the usual suspects
APC/Wincache for local caching
Redis/Memcache for distributedcaching
There’salso a CDN in Azure
Untilyesterday, hooked up to blob storage
Now usable on Azure Roles (web farms)
Will honourcaching headers fromdynamic content
Understandshttps
Understandsquery string

Where are wenow ?
Sql Azure driver : done
Blob storage module : in progress
Needs to plug in the CDN
Leverage the authorizationmechanism
Deployment & updates : justbeginning
Azure has instant-switchbetweenstaging & prod
Plus hot database backups
We’relookingatotherprojects to help
