DESCRIPTION
Is it secure & scalable? Is it difficult? Is it being over-hyped? "Cloud Computing" is a buzzword that's tossed around a lot these days to describe the direction in which infrastructure seems to be moving. It’s a new platform, yet familiar. Microsoft's Windows Azure and SQL Azure cloud computing platform integrates all the capabilities of a Platform-as-a-Service (PaaS) that provides you with highly scalable, secure and agile IT environment. Microsoft is investing heavily across our products & services to deliver the world’s most robust computing platform & applications – whether you want traditional, hybrid or cloud computing models. This session will address each area of architectural interest – from security, scalability, connectivity, development & storage.

• 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
worker roleweb role
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

• 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

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.
