- 6. Myths.. 7
- 7. Myths.. • It is not safe to move to Cloud.. Security??? • We will be locked into one vendor and lose control of its data, if it moves to the cloud. • My company must move all its applications to a cloud service to be able to benefit fully from cloud computing. • Only a small business can gain any cost savings benefit out of Cloud Computing. 8

- 9. Cloud computing patterns On and Off Compute On & off workloads (e.g. batch job) Inactivity Over provisioned capacity is wasted Period Time to market can be cumbersome Average Usage Growing Fast Compute Successful services needs to grow/scale Keeping up w/ growth is big IT challenge Average Usage Cannot provision hardware fast enough Unpredictable Bursting Compute Unexpected/unplanned peak in demand Sudden spike impacts performance Can’t over provision for extreme cases Average Usage Predictable Bursting Compute Services with micro seasonality trends Peaks due to periodic increased demand IT complexity and wasted capacity 10

- 19. Windows Azure Storage Scalable storage in the cloud • 100tb per storage account • Auto-scale to meet massive volume and throughput Accessible via REST services • Access from Windows Azure Compute • Access from anywhere via internet • Supporting .NET Client Library Various storage types • Table - group of entities (name/value pairs) • Queue - Simple non-transactional message queue • Blob - Large binary storage • Drives - NTFS VHD mounted into Compute instance 22
- 20. SQL Azure Database • SQL Server relational database model delivered as a service – Support for existing APIs & tools – Built for the cloud with high availability & fault tolerance – Easily provision and manage databases across multiple datacenters • SQL Azure provides logical server – Gateway server that understands TDS protocol – Looks like SQL Server to TDS Client – Actual data stored on multiple backend data nodes 23
- 21. Building Block Services Distributed, in-memory cache for Windows Azure apps Caching Session state provider for Windows Azure applications .NET client library for caching data Access Authn support using multiple identity providers Easily integrate Live ID, Facebook, Yahoo, Google, & AD Control Support for industry standards and existing .NET APIs Messaging & connectivity for building distributed Service Bus and loosely-coupled apps in the cloud Enables hybrid apps across both on-premises & the cloud Queues & Topics for persistence & pub/sub messaging 24
- 22. Data Services – SQL Server Reporting provided as a service – Reports authored using existing tools (BIDS) Reporting – Reports can include rich Data Visualizations (Maps, Charts, Tablix) and exported to variety of formats – Directly viewed in the browser or rendered as part of an app using the Reporting Viewer control – Web Service interface to render & manage reports – Synchronize data from on-premises SQL Server to/from SQL Azure in the cloud Data Sync – Synchronize data between SQL Azure databases potentially in different data centers 25
- 23. Microsoft Azure Data Centers • Windows Azure runs on 8 datacenters around the world • Enabling you to deploy and run applications and infrastructure close to your customers. 26
- 24. Windows Azure Instance Sizes Variable instance sizes to handle complex workloads of any size Unit of Compute Defined 27
- 25. Summary Windows Azure provides a comprehensive set of services that you can selectively compose to build your cloud apps Global Data Center Footprint 99.95% Monthly SLA. Pay only for what you use. Flexible & Open Compute Options Virtual Machines, Web Sites, & Cloud Services Managed Building Block Services SQL Database, Cache, Service Bus, & more 29

- Speaking Points:There is a lot of talk in the industry about different terms like Platform as a Service, Infrastructure as a Service, and Software as a Service.Since PDC08 when we first announced the Windows Azure our focus has been on delivering a platform as a service offering where you can build applications. Where the platform abstracts you from the complexities of building and running applications. We fundamentally believe that the future path forward for development is by providing a platform. In fact, as you’ll see in a few minutes, we believe that there are a number of new capabilities that should be delivered as services to the platform.Notes:There is a lot of confusion in the industry when it comes to the cloud. It’s important that you understand both what is happening in the industry and how we think about the cloud. This is the most commonly used taxonomy for differentiating between types of cloud services.The industry has defined three categories of services:IaaS – a set of infrastructure level capabilities such as an operating system, network connectivity, etc. that are delivered as pay for use services and can be used to host applications. PaaS – higher level sets of functionality that are delivered as consumable services for developers who are building applications. PaaS is about abstracting developers from the underlying infrastructure to enable applications to quickly be composed. SaaS – applications that are delivered using a service delivery model where organizations can simply consume and use the application. Typically an organization would pay for the use of the application or the application could be monetized through ad revenue. It is important to note that these 3 types of services may exist independently of one another or combined with one another. SaaS offerings needn’t be developed upon PaaS offerings although solutions built on PaaS offerings are often delivered as SaaS. PaaS offerings also needn’t expose IaaS and there’s more to PaaS than just running platforms on IaaS. ----Slide Objectives:Explain the three established terms in the industry for cloud servicesSpeaking Points:With this in mind, it’s important to understand how to talk about our Cloud Services offerings.There is a lot of confusion in the industry when it comes to the cloud.
