  • Slide Objectives:Explain that there are different VM instance sizes available within Windows AzureSpeaking Points:---Speaking Points:One of the key areas of feedback has been to reduce the cost and size of Windows Azure instances. At PDC we will announce..Notes:(*) 20GB with a limitation on VHD size if they are deploying VMRole on XSmall: the VHD can only be up to 15GB.each tenant can support 20 instances just like regular subscriptions with Small VM. We do not scale based on core counts.There is no SLA on the network bandwidth for each VM size as this resource is shared among all the VM. That said, we need to provide guidance for customer so they could design their applications correctly. From the engineering side, this is what we mean by Low, Moderate and High. • Low currently means 0-15Mbps with short burst up to 25-50Mbps (Megabit/s). These are sufficient for some web sites with low traffic. • Moderate means 0-100Mbps with short burst up to 200Mbps (100Mbps is the norm). This is what we currently reserve for the Small VM.• High means 200-800 Mbps. If you divide this into 3 spectrums for Medium, Large and XL. Then Medium is in the low end, Large hovers around the middle zone and of course XL takes the high-end spot.These rates should be used as guidance. Nothing can beat a test run to see what the application requires but using these bandwidth ranges, hopefully it reduces the guess work for the customers
  • Slide ObjectiveExplains the use of SQL Azure as a backing storeSpeaking NotesThe Out of the Box SQL ServerASP.NET Session State mechanism is not suitable for AzureRelies on SQL Server Agent which is not available in SQL AzureWill need to implement a custom session state providerStore and retrieve stateCleanupWill probably want to use some sort of partitioning mechanism. Partitioning is a feature in the ASP.NET provider interfaces… so just need to implement the mechanism to reolsve the partitionFor more on partitioning see the day 2 storage strategies sessionSQL Azure is cost competitiveParticularly in high and consistent load scenariosSQL Azure does not have the storage transaction charge SQL Session state generally only requires a small amount of storageScale out across 1GB SQL Azure databasesNotes3rd party Sql Azure session state providerhttp://azuresqlsession.codeplex.com/wikipage?title=Home&ProjectName=azuresqlsession
  • Slide ObjectiveDiscusses managing DNS entries for Windows Azure Web Role hosted sitesSpeaking NotesFor all intents and purposes Windows Azure IPs are fixed. They are fixed for the lifetime of a deploymentThey remain fixed even when you VIP SwapTherefore you can comfortably create A records against the IP address for your production slot. This will save you the double lookup for a CName record.It will also allow you to create an entry for the root of a domainSo the approach for high performance DNS is as followsCreate your hosted service Deploy into the production slot nslookup myapp.cloudapp.net to get the IP Create A records for www.myapp.com and myapp.com with a decent length TTL Run your service doing rolling upgrades and VIP swaps till your hearts content If you need to delete your deployment (e.g. to reconfigure external endpoints) then you should; lower the TTL on the A recordswait till the old TTL expirescreate a new servicedeploy to prod slotNSLookupswap the IP on the A records delete the old deployment.NotesGood threadhttp://social.msdn.microsoft.com/Forums/en/windowsazure/thread/fa00d06d-b631-46ce-af66-f463cf667282

  • Slide ObjectiveDiscusses the approach of using Cookies to hold state.Speaking NotesAvoiding session state and simply pushing the state to the client as a cookieCould implement a session state provider on top of this approachAvoids the need to roundtrip to/from the database or storage each requestWorth comparing the perf difference between the two approachesDon’t forget that cookies are sent back and forth with every HTTP request- e.g. if you serve images from your Web Role you will end up with cookies being sentCan use an alternative Host header in order to avoid thisCan also use Windows Azure Blob storage to serve images and other static content.Notes

  • Recommended demos from the Windows Azure Training Kit:Hello Windows Azure
  • Slide ObjectiveWindows Azure allows for 2 deployment packages as part of the same project, Production and StagingSpeaking PointsStaging Costs money to useFlip aroundEach package has a unique version for that project.The “production” package services requests from the website URL. Worker roles operate normally.Any package in “Staging” will only serve web requests from a temp URL – which is a GUID and is shown below the package. This is great to run smoke tests on.
  • Slide ObjectiveHighlight the stages of a typical deploymentLocal development Hybrid of local and Windows Azure Everything in Windows Azure in staging Swap from Staging to ProductionSpeaking PointsDebugging is not currently supported in Windows AzureSet breakpoints & debug in Local Development Fabric.Test initially with development storage, but test with Windows Azure storage to test with large volumes of data whilst still keeping your roles local for debuggingOnce you are happy with the Worker/Web Roles running locally deploy everything to Staging and run tests in this environmentOnce all tests in staging pass, promote everything to productionWorker roles in the “Staging” project are operational – and as such will process messages from queues etc. You should design for this.
  • Slide ObjectiveCODE – PACKAGE – UPLOAD – DEPLOYShows how service makes it from code living in Visual Studio to a running deployed instance in Windows AzureShow how Roles are packaged up and uploaded with the config to Windows AzureSpeaking PointsCode is compiled, then packaged into a single file. This is the service package.This, along with the configuration/service model – are deployed via the web portal.NotesVisual Studio 2010 with the updated tools now supports automated seamless package/upload/deploy using Service Mngt Api
  • Slide ObjectiveDemonstrating the Publish and Deploy features included with Visual Studio 2010Speaking PointsA Windows Azure subscription. When you first sign up to Windows Azure a subscription is created and associated with your Live IDTo find your subscription ID, navigate to the Account page in the Developer Portal. Subscription ID appears in the Support Information section at the bottom of the page.A Windows Azure hosted service. Before you can deploy your cloud service, you need to create a hosted service for that deployment. The hosted service provides the two deployment slots, Staging and Production, to which you can deploy your cloud service.A Windows Azure storage account. When you deploy your cloud service through Visual Studio, the service package is first uploaded to a blob through the specified storage account, then deployed to Windows Azure from the Blob service

  • Slide ObjectiveDiscuss achieving very high availability with Windows AzureSpeaker NotesFault Domain is a physical unit of failure, and is closely related to the physical infrastructure in the data centers. In Windows Azure the rack can be considered a fault domain. However there is no 1:1 mapping between fault domain and rack. Windows Azure Fabric is responsible to deploy the instances of your application in different fault domains. Obviously this only applies if you run more than 1 instanceRight now Fabric makes sure that your application uses at least 2 (two) fault domains, however depending on capacity and VM availability it may happen that it is spread across more than that. As a developer u have no direct control over how many fault domains your application will use but the way you configure it may impact your availabilityUpgrade Domain is a logical unit, which determines how particular service will be upgraded. The default number of upgrade domains that are configured for your application is 5 (five). You can control how many upgrade domains your application will use through the upgradeDomain configuration setting in your service definition file (CSDEF). Windows Azure Fabric ensures that particular upgrade domain is not within single fault domainThat is Upgrade domains are orthogonal to fault domainsRoles are then spread out over upgrade domains and fault domains. Subject to running a reasonable number of instances this removes the risk of a single point of failure
  • Slide ObjectiveIntroduce the very basic service model that we’ll be working with as we discuss fault and upgrade domainsSpeaker NotesWe’ll be looking at fault an upgrade domains in the context of a very simple serviceThe model defines two roles- a worker and a we roleEach of these is running four instances
  • Slide ObjectiveProvide a graphical view of fault and upgrade domainsSpeaker NotesYou can se that our service is well spread out across both fault and upgrade domainsThe loss of a fault domain will not cause a failure of our service nor will the restart or change of an upgrade domain cause a failure of our serviceNotesUseful pre-reading here.http://blog.toddysm.com/2010/04/upgrade-domains-and-fault-domains-in-windows-azure.html
  • ObjectiveIntroduce the VIP Swap mechanismSpeaker NotesVIP swapping allows for minimal downtime upgrades by running two deployment slotsThe load balancer is re-wired when a VIP swap is performed to change the deployment slot that is listening on the production URL (the production IP address also remains unchanged during a VIP swap)You can upgrade your service by deploying a new package to the staging deployment slot and then swapping the staging and production deployments. This type of upgrade is called a Virtual IP or VIP swap, as it swaps the addresses of the two deployments. Both deployments remain online during the swap process.If u do a VIP swap you should aim to be running the same number of instances in both slots prior to the swapEnsure instances in staging are running and warmed (consider using inter role communication to warm up instances)Do not want to VIP Swap a 100 instance role and suddenly grind to a halt while the machines JIT your code.VIP-Swap is done between the Production and Staging deployments in Windows Azure During VIP-Swap the VIP of the Production deployment is assigned to the Staging deployment, and the VIP of the Staging deployment is assigned to the Production one (both VIPs are swapped – hence the term VIP-Swap) NotesPerforming VIP Swap Upgradeshttp://msdn.microsoft.com/en-us/library/ee517253.aspx
  • Provides a diagrammatic view of a VIP SwapStart with just the production slot deployedPerform a deployment into the staging slotThe VIP swap is then performed repointing the IPs at the load balancer level.
