Notas do Editor
- Slide Objectives:Explain the differences and relationship between IaaS, PaaS, and SaaS in more detail.Speaking Points:Here’s another way to look at the cloud services taxonomy and how this taxonomy maps to the components in an IT infrastructure. Packaged SoftwareWith packaged software a customer would be responsible for managing the entire stack – ranging from the network connectivity to the applications. IaaSWith Infrastructure as a Service, the lower levels of the stack are managed by a vendor. Some of these components can be provided by traditional hosters – in fact most of them have moved to having a virtualized offering. Very few actually provide an OSThe customer is still responsible for managing the OS through the Applications. For the developer, an obvious benefit with IaaS is that it frees the developer from many concerns when provisioning physical or virtual machines. This was one of the earliest and primary use cases for Amazon Web Services Elastic Cloud Compute (EC2). Developers were able to readily provision virtual machines (AMIs) on EC2, develop and test solutions and, often, run the results ‘in production’. The only requirement was a credit card to pay for the services.PaaSWith Platform as a Service, everything from the network connectivity through the runtime is provided and managed by the platform vendor. The Windows Azure Platform best fits in this category today. In fact because we don’t provide access to the underlying virtualization or operating system today, we’re often referred to as not providing IaaS.PaaS offerings further reduce the developer burden by additionally supporting the platform runtime and related application services. With PaaS, the developer can, almost immediately, begin creating the business logic for an application. Potentially, the increases in productivity are considerable and, because the hardware and operational aspects of the cloud platform are also managed by the cloud platform provider, applications can quickly be taken from an idea to reality very quickly.SaaSFinally, with SaaS, a vendor provides the application and abstracts you from all of the underlying components.
- Slide ObjectiveUnderstand that Microsoft has a long history in running data centres and online applications. Bing, Live, Hotmail etc….Understand the huge amount of innovation going on at the data center levelSpeaking Points:Microsoft is one of the largest operators of datacenters in the worldYears of ExperienceLarge scale trustworthy environmentsDriving for cost and environmental efficientlyWindows Azure runs in 3 regions and 6 datacenters todayData center innovation is driving improved reliability and efficiencyPUE = Power Usage Effectiveness = Total Facility power/IT Systems Power = Indication of efficiency of DCUnder 1.8 is very good, modern cloud DCs approaching 1.2Multi-billion dollar datacenter investment700,000+ square foot Chicago and the 300,000+ square foot Dublin, Ireland data centersMicrosoft cloud services provide the reliability and security you expect for your business: 99.9% uptime SLA, 24/7 support. Microsoft understands the needs of businesses with respect to security, data privacy, compliance and risk management, and identity and access control. Microsoft datacenters are ISO 27001:2005 accredited, with SAS 70 Type I and Type II attestations.Notes:http://www.globalfoundationservices.com/http://blogs.msdn.com/the_power_of_software/archive/2008/06/20/microsoft-s-pue-experience-years-of-experience-reams-of-data.aspxhttp://blogs.msdn.com/the_power_of_software/archive/2008/06/27/part-2-why-is-energy-efficiency-important.aspx
- Speaking Points:At PDC10 in just over a month, we will introduce several new services including: Caching and Reporting. We will also have a new CTP for the Data Sync Service and Project Dallas will be finally available. Let’s drill into these services in a bit more detail.--Speaking Points:I suspect most if not all of you in this room are familiar with the Windows Azure Platform today.Today the platform consists of a set of foundational services SQL Azure relational databaseAppFabric provides services that can be used by any apps – hosted in Windows Azure, on-premises, or hosted in another environment. Questions:How many of you are building applications for Windows Azure?How many are using SQL Azure?How many are using the Access Control service today? The Service Bus?Notes:Windows Azure StoryWe are building an open platform to run your applications in the cloud. Your apps are .NET, Java, PHP, etc. We love everyone.We are going to help you migrate your existing apps to the cloud. The cloud platform is the future. Enables scale, self-service, lowers friction, etc. We provide the best cloud platform for building new apps. (aka n-tier, web services, etc.)
- Slide ObjectiveUse this slide to transition into an explanation of SQL Azure Database (Reporting and Data Sync will be covered later)Explain at a high level how SQL Azure worksSpeaker NotesDesign Principle of SQL Azure: Focus on combining the best features of SQL Server running at scale with low frictionSQL Azure is a high availability databaseAlways three transaction consistent replicas of the databaseOne primary replica; two slave replicasFailure of a replica will result in another replica being spun up immediately by the fabricFailure of the primary replica means a slave replica will become the primary and a new slave will spin upMinimal down timeTypically just a few dropped connectionsEasy to code for the failover scenario- if you are ding god connection management and error handling will be fineClustered index required on all tables to allow replicationNotesUseful article from SQL Azure teamhttp://msdn.microsoft.com/en-us/magazine/ee321567.aspx
