AgendaGet ready for the cloud
The cloud is important!We do not have supported Azure here yet
All about planning & current applicationsThe Azure talk with no Azure bits

Virtualisation!
Virtualise todayLimited big hardware vs. lot’s of small cheap hardwareLearn what is a problem in virtualisation
VM Hosting (IaaS)Create a Hyper-V imageUpload imageHow do people access that image?What about state?

Our Demo Story For Today
NASA gets ~3 500 applications for ~15 spotsDisqualifies ~700 for Medical, Educational, Professional etc…
Just a simple: Submit data > Parse > Analyse

Do you know CodePlex?ZeroMQ

Data Design Proven Practises
Choose where appropriateRelational data: SQL Server ≡ SQL AzureBlobs: File system ≡ Blob storageQueues: MSMQ ≡ AppFabric 2.0
Potential pain areasLimited Data TypesKeep Data Size, Growth & Transaction Volume in min
Reduce logic in SQL databases
15
Connectivity Design Proven Practises
Interface (contract) based designUses standardsAbstract the connectivity layer away from the logic layer* non marketing way to tell you to use WCF
16
Features we want in processing
ASAP Asynchronicity Light with data Great WCF, REST & oData supportPersistableMonitoring * Caching *

Application Design Proven Practises
Lego againSmall pieces that do a job (function)Can operate independently
Worker rolesGreat for processing, better than web rolesCan run forever! …. Not really Expect the “Chaos Monkey” sometimes
21
Worker Role?
App Queue Worker Role Service

Regulation & Compliance
Where is your data stored?Personal info can’t leave the country*Store locally, process in the cloud
25
Security Design Proven Practises
Security Golden Rule: Don’t roll your own You should prefer an external identify provider for AuthN & AuthZ Development Options
Today: WIF “Tomorrow”: AppFabric Access Control 2.0 (Labs)
26
Why use WIF?
App

Active Directory

AD, OAuth, etc…

How does this cloud?

29
Deployment Design Proven Practises
Plan, plan, planWork on DNS and control that DNSUse IPv6 for forward thinking with Azure Connect
Packaging and Configuration is KEYPackage Application Binaries and Configuration Separately
Automate your deploymentsBuild components exist
