  3. 3. Logique Métier … Ajouter de nouveaux locaux Ajouter de nouvelles fonctions en « live » Appliquer les patchs OS Middleware & Diagnostiquer les défaillances de services Administration Ajouter des capacités de stockage Gérer les augmentations de trafic Prévoir les défaillances matérielles Datacenter
  4. 4. Dynamics Windows Google App Azure Salesforce CRM , Azure Engine, EC2 Services Gmail Exchange Fabric Force Platform Online (Raw) IaaS PaaS SaaS Cloud Computing Utility Computing Grid Computing Super Cluster Computing Computing
  5. 5. Feature Microsoft Amazon Google VMware Availability CTP (Alpha) Yes, commercially available In public beta Announced Computing You provide .NET code for front-end and back- Elastic Compute Cloud (EC2) You write your web Lets you easily move your virtual Architecture end servers which allows you to upload your XEN application in Python or machines between environments Microsoft then runs on Windows 2008 virtual virtual Django with a specific and machines according to your machine images to the set of limitations set by run them on premise or at any environment specifications (how many machines infrastructure and gives you APIs Google and submit the partner datacenter. of each kind you need, and so to instantiate and application code to them. on.) manage them. Load balancing Yes Yes Yes Not announced Storage Yes: application storage and SQL services Yes: Simple Storage Service (S3) Yes: database Datastore Not announced and SimpleDB APIs Message queuing for Yes: queues in Windows Azure storage Yes: Simple Queue Service No Not announced machine (SQS) communcations Integration with other So called .NET services (aka BizTalk in the No Yes, with existing Google No services cloud): services: authentication, Access control services, workflow service, mail, base, calendar, service bus. contacts, documents, Live Mesh pictures, spreadsheets, Various Live services (contacts, mail, maps and YouTube. so on.) At the moment, all these components do not seem to be integrated with the solution but rather bundled. Tied to the vendor Yes Yes Yes No, the VMs can be hosted by any datacenter of the partners or used on-premise Development tools Yes, integration into Visual Studio, support for Not applicable. Amazon simply Yes, have basic editing, Not applicable. VMware simply any .NET languages, runs your virtual machines and local simulation, and runs your virtual machines and does not deployment tools. does not care which development platform Language selection care which development platform you are using on top of the base limited to Python and you are using on top of the base OS. Django. OS Application-level tools such as Google Web Toolkit (GWT) do not seem to have any integration with Google App Engine.

  20. 20. Développement d’un service Test et débogage en local Déploiement sur le « cloud » Maintenance d’un service disponible
  21. 21. Visual Studio Projets « templates » Débogage disponible Platefome .Net .Net, IIS7, WCF « The cloud on your desktop » Bouchons disponibles ( mode offline )
  22. 22. Total compute usage: 2000 VM hours Cloud storage capacity: 50GB Total storage bandwidth: 20GB/day
  23. 23. Scale-out not scale-up Add and remove capacity on demand Pay for what you use as you go Automation is key to reducing costs
  24. 24. Failure of any given node is expected View each node as a cache State has to be replicated No one-time install step Applications need to reinitialize on restarts Do not assume previous local state is available Configuration changes due to load or failures Handle dynamic configuration changes
  25. 25. Services are always running Service rolling upgrades/downgrades Services must handle data schema changes Services are built using multiple nodes/roles Document service architecture Document communication paths of elements Services can grow very large Careful state management at scale is needed
  26. 26. Windows Azure manages services not just servers Tell it what you want, and it will automate the details System manages services, nodes, and network Automates service life-cycle management Model-driven automation Allocation, deployment, and service-level management Turns pool of physical resources into shared compute fabric Pay for what you use Platform insures service isolation
  27. 27. Goal is to automate life cycle as much as possible Maintain Provisionin Deploymen Coding and goal state g t Modeling  Desired  New   Mapping and Monitor configuration services deploying to  React to and actual events updates hardware  Network configuration Automated Automated Developer/ Developer Deployer
  28. 28. Describes service as distributed entities Authored by service developer Configured by service deployer Logical description of the services Same model used for testing and production Mapped to actual hardware at deployment time Powerful declarative composition language Can describe simple to very complex services
  29. 29. Public Internet Template automatically maps to service model Frontend Background Web Process Role Role Load Balancer Fundamental Services Load Balancer Channel Endpoint Interface Directory Resource
  30. 30. Service Set of roles, groups, and channels Role Program, execution entity Group Set of other groups, roles and channels Endpoint Communication end point exported by role Channel Logical load-balancers and switches Interface Exposed by services Configuration settings Developer settings System settings
  31. 31. Service de Vidéoconférence
  32. 32. Windows Azure PDC release Automated service deployment from bare metal Subset of service model – simple set of service templates Support for changing number of running instances Simple service upgrades/downgrades Automated service failure discovery and recovery Automated hardware management Include automated network load-balancer management In calendar year 2009 Expose more of underlying service model Richer service life-cycle management
  33. 33. Windows Azure PDC release Managed code/ASP.net Running in fixed-sized VM instances External virtual IP address per service Service network isolation enforcement In calendar year 2009 Native code support Richer network support Also, in 2009 will be in multiple data centers
  34. 34. Cloud services have specific design considerations Always on, distributed state, large scale, and failure handling Windows Azure is an operating system for the cloud Scale out, dynamic, and on-demand Windows Azure manages services not just servers Tell it what you want, and it will help automate the details Windows Azure frees developers from many platform issues Allows developers to concentrate on application logic instead of platform issues
  35. 35. Extend existing Deploy Complete Compose New Application On-Premise Application Application in the Cloud from Cloud Services 79

  39. 39. • Parallel and distributed processing • Image processing and rendering • Media content transcoding and publishing • Share-able reference data • Search indexes, Catalogs • Maps, profiles, blogs, files, documents, etc. • Composite services, mashups • Multi-enterprise business applications (MEBA) • Inter-organizational (B2B) business processes • Extend enterprise SOA to other enterprises
  40. 40. Learn Build Extend  Download the SDK’s & build  Find out more at  Provide feedback on www.azure.com your service/application technology & model  Use MSDN resources  Provision & deploy your  Participate in blogs & msdn.microsoft.com/en- service on Azure forums us/azure  Participate in readiness activities
  41. 41. Limitations liées à l’aspect distribué
  42. 42. Les applications distribuées sont très différentes des applications centralisées ou client/serveur ! Hypothèses fausses sur le réseau !!! 1 – Le réseau est fiable. 5 – La topologie ne change pas. 2 – La latence est nulle. 6 – Il y a un administrateur. 3 – La bande passante est infinie. 7 – Le transport ne coûte rien. 4 – Le réseau est sécurisé. 8 – Le réseau est homogène. • Le réseau n’est simplement pas un composant – Le réseau introduit de la latence – Le réseau est “partitionné” par la latence 3 4 1 2 Latence
  43. 43. • Le théorème CAP (Consistency, Availability, Partition) – “There are three properties that are commonly desired: consistency, availability, and partition tolerance. It is impossible to achieve all three at the same time. • Consistency + Availability A C • Single site / Cluster database P • Two phases commit • Consistency + Partition A C • Distributed database / Distributed looking • Pessimistic looking P • Availability + Partition A C • Distributed cache/ DNS P • Optimistic looking
  44. 44. Contexte des applications Fondamentalement Partitionnées (latence) latence réseau => Partition du SI Restent Consistance et Disponibilité Objectifs des applications ? Hautement Disponibles => recherche de Disponibilité Donc Consistance doit être relaxée réplication (systèmes de fichiers, SGBDs)
