Abbattere i costi di gestione per le aziende è fondamentale in un periodo come quello attuale. Adottare una soluzione cloud comporta notevoli vantaggi per le piccole, medie e grandi imprese, permettendo di concentrarsi nella fase di sviluppo piuttosto che nella gestione dell'infrastruttura IT. La diretta presenterà gli scenari di utilizzo, declinati nelle diverse modalità di accesso (IAAS, PAAS, SAAS) e che cosa significa interagire con le piattaforme per il Cloud Computing fornite da alcuni dei protagonisti quali Amazon, Microsoft, Google.

- 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 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.

- Slide ObjectiveIntroduce users to the tooling available to work with Windows AzureSpeaker NotesDeveloper SDK is a Cloud in a box, allowing you to develop and debug locally without requiring a connection to the cloud. You can do this without Visual Studio as there are command line tools for executing the “cloud in a box” and publishing to the cloud.There is also a separate download for the Visual Studio 2008 tools, which provide the VS debugging and templates. This in turn includes the SDKDownload the VS tools if you use VS. Download the raw SDK if you use alternative platforms (PHP etc…)Requirements for Win 7 or Win 2008 are a dependency on IIS7 for the development fabricCan install the bits with the Microsoft Web Platform InstallerNotesWindows Azure Tools for Microsoft Visual Studio includes:C# and VB Project creation support for creating a Windows Azure Cloud Service solution with multiple roles.Tools to add and remove roles from the Cloud Service.Tools to configure each Role.Integrated local development via the Development Fabric and Development Storage services.Running and Debugging a Cloud Service in the Development Fabric.Browsing cloud storage through the Server ExplorerBuilding and packaging of Cloud Service Packages.Deploying to the Windows Azure.Monitoring the state of your services through the Server Explorer.Debugging in the cloud by retrieving IntelliTrace logs through the Server Explorer.
- Slide ObjectiveExplains the operation of Session state in Windows Azure multi instance rolesSpeaking NotesMust move session state off the Web Role instances In this animationFirst request hits one instanceSubsequent request hits another instanceAt the end of the animation the value of Foo is hard to determine.Is it 1, 2 or null?Will depend on which server the LB routes our request toNotes
- Slide ObjectiveTo introduce the concept of local storageSpeaker NotesA local storage resource is a reserved directory in the file system of the virtual machine (VM) in which an instance of a role is running. Code running in the instance can write to the local storage resource when it needs to write to or read from to a file. For example, a local storage resource can be used as a temporary folder when manipulating data or generating documents.Local storage is never guaranteed as persistent; CleanOnRoleRecyle = false is useful to minimise need to rebuild cache for exampleFor guaranteed long term drive based storage- e.g. to hold database files. Use Windows Azure Storage DrivesNoteshttp://msdn.microsoft.com/en-us/library/ee758708.aspx
- Slide ObjectiveGet a graphical overview of hybrid partitioningSpeaking notesHybrid partitioning combines both vertical and horizontally partitioningIN this example the large data is first partitioned off into Windows Azure StorageThen the data remaining in SQL Azure is horizontally partitionedNotes
- Slide ObjectivesUnderstand each of the storage types at a high levelSpeaker NotesThe Windows Azure storage services provide storage for binary and text data, messages, and structured data in Windows Azure. The storage services include:The Blob service, for storing binary and text dataThe Queue service, for storing messages that may be accessed by a clientThe Table service, for structured storage for non-relational dataWindows Azure drives, for mounting an NTFS volume accessible to code running in your Windows Azure serviceProgrammatic access to the Blob, Queue, and Table services is available via the Windows Azure Managed Library and the Windows Azure storage services REST APINoteshttp://blogs.msdn.com/b/windowsazurestorage/archive/2010/03/28/windows-azure-storage-resources.aspx
