Two Independent Environments

Production Staging

Production Staging

Stages of Service DeploymentStage 1: Local development and testing

Development Fabric

Development Storage

Stage 4: VIP Swap to Production

Stage 3: Test in Staging on Windows Azure Fabric

Windows Azure Fabric

Stage 2: Test in mixed mode with hosted data

Deploying a Cloud Service from Visual StudioPublish to either Production or StagingPackage only or Deploy to Windows AzureThree things neededWindows Azure subscriptionWindows Azure hosted serviceWindows Azure storage account

Uses x509 certificate authentication

Geo-Location & Affinity GroupsDependent resourcesEnsures geo-locationin single datacentreCan specify sub-region also (Recommended)

Explicitly define sub-region on service by service basis

Windows Azure chooses sub-region(Not Recommended)

Affinity and Geo-Location Settings are Immutable

Guest OS VersioningWindows Azure Runs on Base OSBase OS revised regularlyBest practice is to specify OS versionGet latest version by default – using version ‘*’ gets auto-updatesUse osVersion attributeTo determine version in the cloud view config data in cloud<ServiceConfiguration serviceName="CloudService1“ osVersion="WA-

X.509 CertificatesManagement Service uses certificates for authenticationSelf-signedAny valid X.509 v3 with key length >= 2048 bits

makecert -r -pe -a sha1 -n CN=AzureMgmt -ss My -sky exchange "AzureMgmt.cer" Creates a new self-signed certificate, writes it to the "AzureMgmt.cer" file in the current directory and saves it to the CurrentUser\My certificate store.

Preparing to use Management APIMake / Acquire CertificatePay attention to ValidFrom,Local date could differ from Server

Minimizing Downtime

Fault & Upgrade DomainsFault DomainsRepresent groups of resources anticipated to fail togetheri.e. Same rack, same serverFabric spreads instances across fault domainsDefault of 2

Upgrade DomainsRepresents groups of resources that will be upgraded togetherSpecified by upgradeDomainCount in ServiceDefinitionDefault of 5

Fabric splits Upgrade Domains across Fault Domains and Across Roles

Debugging

Debugging a Service in DevelopmentDebugging only supported in Development FabricVisual Studio attaches to all instances when debugger startsCan edit configuration whilst debuggingManaged Debugger by DefaultNative Code Debugging is supported

IntelliTraceIntended for Debug Scenarios OnlyRequires .NET 4 & Visual Studio 2010 UltimateMust be enabled when publishing serviceChild processes cannot be IntelliTrace debugged
