• it’s common to divide cloud platforms into two categories:– infrastructure as a service (IaaS)• you create and control your own vm• example: amazon.

– platform as a service (PaaS)• you provide only an application to run• examples: google and force.com

• microsoft’s cloud platform (windows azure) is most often viewed as PaaS– the distinction is blurry, however

flexible service architecture

• a service consists of:– isolation boundary

• component roles – roles can be web role…– or worker role

• with endpoints– numbered identical

instances of each role• …all specified in a

service model

applications are packaged

• application binaries etc• service model:– serviceconfiguration.cscfg –

dynamic change• # instances of each role

– servicedefinition.csdef – fixed• which roles make the app

storage architecture

• a storage service consists of:– isolation boundary

• storage types:– blob– table– queue

• http://mystore.blob.core.windows.- net/planky/splat

• blobs:– “files”– permissions

• tables:– structured (not relational)

• queues:– web worker role

storage

• lots of space… pay only for what you use• distribution• scalability– performance stays the same as load increases

• replication: data written 3 times• instantly/strongly consistent• geo-distribution: choose the location

connecting to the outside world

windows azure application fabric

• service bus• access control service– authentication:• adfs• google, liveID, yahoo, facebook

– claims mapping:• buyer from fabrikam purchaser in adatum

sql azure

• microsoft’s rdb in the cloud• “sql server as a service” (is that SQLaaS ???)• management:– sql server management studio

• sql coding:– tools you know: ado.net

• “it’s just sql server”…• max db size: 50gb… sharding.
