This document provides an overview of how various Azure services can help address common needs and challenges for a company called Litware. It discusses how Litware can leverage Azure Identity and Access Control services to enable single sign-on for customers using different directories. It also describes how Litware can use the Service Bus to integrate with customers' on-premises applications in a secure manner. Additionally, the document outlines how Workflow services could help Litware and customers create custom extensions more easily. Finally, it mentions how SQL Data services could help with Litware's database integration needs for different types of data.
Introducing Windows Azure
- 1. Windows [email protected] introduction to Cloud computingPresented By:Mohamed Samy Technical Architect, iSource
- 2. Goals and TakeawaysAn understanding of Cloud computingAn understanding of the Azure environmentUnderstanding the new architectureUnderstanding why and when this architecture applies
- 3. AgendaIntroducing Cloud computing 15 minsThe Windows Azure Platform 15 minsThe Azure Data Services 15 mins.NET Services 15 minsHow Cloud computing affects Architecture 15 minsQ & A 15 mins
- 4. AgendaCloud, utility computing – Nice new buzzwordsWhat do they mean?Why do we need this model?Is this the new way of doing things? What do I have to learn?
- 5. Agenda ContdDemoWhat’s next?Introducing AzureThe Operations Management perspectiveServices in Action
- 6. The cloud
- 9. Evolution Data center Hosted ModelCloud computing
- 10. So what exactly is cloud computing?Offerings from Amazon, Google, Microsoft.Amazon Elastic computing (create your own machine with your choice of OS + APIs)Google Apps and APIHosting VMs in the cloudMicrosoft created a new offering…..
- 11. Anatomy of a Cloud offeringA machine Physical/Virtual hosted in a data center (Hardware)An Operating SystemA framework, APIs and a development environmentMight include end user Apps (web sites, office suites..etc)
- 12. Hosting locally vs. in the cloudHardware costs.Software costs.Administration costs.
- 13. Resource allocationMachines must be chosen to host roles of the serviceFault domains, update domains, resource utilization, hosting environment, etc.Procure additional hardware if necessaryIP addresses must be acquiredProvisioningMachines must be setupVirtual machines createdApplications configuredDNS setupLoad balancers must be programmedUpgradesLocate appropriate machinesUpdate the software/settings as necessaryOnly bring down a subset of the service at a timeMaintaining service healthSoftware faults must be handledHardware failures will occurLogging infrastructure is provided to diagnose issuesThis is ongoing work…you’re never doneDeploying A Service Manually
- 14. ConclusionData centers cost a lot of money.It’s cheaper to outsource these costs and headaches to someone who does this all the time.
- 15. Previous AttemptsUDDI, Web service discoveryCOM+, CORBAIndustry standards started popping up e.g. ws.*
- 16. Introducing the Azure PlatformWhat is it?Essentially a new architectureA Service offering, pay as you goAn OS, APIs + Operations management (The key differentiator IMHO)
- 18. A Look Inside AzureYour Applications…ServiceBusWorkflowDatabaseAnalyticsIdentityContactsAccessControl…Reporting…Devices…ComputeStorageManage…
- 19. MS Approach to Azure ServicesProvide a Flexible Services Platform with Internet ScaleSimple scenarios are simple – complex scenarios are possible
- 20. Services hosted in Microsoft’s data centers
- 21. Designed for high availability & scalabilityBase it on Internet StandardsMultiple protocol support including HTTP, REST, SOAP, Atom
- 22. Broad investment in open, community-based access to Azure servicesExtend Your Existing Investments Familiar tools, languages, and frameworks with .NET and Visual Studio
- 23. Provides the choice to build on-premises, cloud, or hybrid solutions
- 24. Integrate with existing assets such as AD and premises applicationsAzure™ Services PlatformInteroperability
- 26. The Operations management perspectiveWhat is a fault domain?What percentage of my service can fail at one time?What happens if a switch fails?What is an update domain?How do I upgrade my service?What portions can we take down and upgrade without causing failure?
- 27. Allows you to specify what portion of your service can be offline at a timeFault domains are based on the topology of the data centerSwitch failureStatistical in natureUpdate domains are determined by what percentage of your service you will take out at a time for an upgradeYou may experience outages for both at the same timeSystem considers fault domains when allocating service rolesExample: Don’t put all roles in same rackSystem considers update domains when upgrading a serviceFault/Update DomainsFault domainsAllocation is across fault domains

- 33. Windows Azure Service LifecycleGoal is to automate life cycle as much as possibleAutomatedAutomatedDeveloper/DeployerDeveloper
- 34. Purpose: Communicate settings to service rolesThere is no “registry” for servicesApplication configuration settingsDeclared by developerSet by deployerSystem configuration settingsPre-declared, same kinds for all rolesInstance ID, fault domain ID, update domain IDAssigned by the systemIn both cases, settings accessible at run timeVia call-backs when values changeDynamic Configuration Settings

Editor's Notes
- #7: Here is where I explain where the cloud came from, where did we get this terminology? What does it represent?What is the network that anyone can connect to anywhere?What is the network that can be used by the most number of devices?
- #18: Explain mesh
- #23: Switch failure = all servers loosing connectivity
- #36: Litware
