platform or infrastructure? 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 vm IaaS os vm platform PaaS database database your application your application local storage local storage fabric

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 web role worker role 1 1

applications are packaged worker role web role 1 application binaries etc service model: serviceconfiguration.cscfg – dynamic change # instances of each role servicedefinition.csdef – fixed which roles make the app app.cspkg – application package Application

fabric is the core for paas demand time

all is hidden… 1 1 2 sla 99.9% uptime 40 mins/ month backup load balancer security patches sla 99.9% uptime software patches 1 1 service patches 40 mins/ month service packs 2 instance management

storage architecture a storage service consists of: blobs: http://mystore.blob.core.windows.- net/planky/splat blobs: “files” permissions tables: structured (not relational) queues: web   worker role a storage service consists of: isolation boundary storage types: blob table queue planky splat

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

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.
