  1. Cloud Computing in the Enterprise From Enterprise IT in the Cloud Computing Era New IT Models for Business Growth & Innovation, Frank Gens, SVP & Chief Analyst, IDC Cloud Services Architecture:Making sense of *aaS, ben.reid@ .com

  2. (Good Luck) Defining Cloud Computing • Software-as-a-Service • “My customer resource management (CRM) system is out on the Internet!” • Grids vs. Clouds • Shared Virtual Resources • Batch Jobs vs. Online Applications • Different Approaches to State Management • Network Diagrams • A service is “on a cloud somewhere” • Virtualization Platforms & APIs • Hardware can be manipulated with software

  3. What problems are we trying to solve? 1. Cost 2. Scalability 3. Flexibility 4. Availability 5. Portability 6. Collaboration 7. Enable new stuff that we couldn't do before!

  4. "The cloud" - undersea cable view

  5. The cloud - datacenter view • Massive build-out happening right now • Google, Microsoft, Amazon, Yahoo are tier 1 • HP (EDS), IBM, Rackspace? • Scale is key

  6. The cloud - logical view • The Cloud: The Universe of all Web Services

  7. The "cloud" - definitions and hype Is the "cloud": • Infrastructure aaS? • Grid / utility / "on demand" computing • Shared utility • eg Amazon EC2 • Platform aaS? • Ready-for-deployment scalable application platform • Google apps, Force.com, Heroku, Bungee Labs • Microsoft! (Azure) • Software aaS? • Used to be called "application service providers" • Multitenanted architectures: SalesForce.com,Xero • ...many, many others (3000 worldwide at least) • Wide area SOA? • "Universe of all (web) services" • WS-* and REST (and Etch?) standards • Data as a service? (StrikeIron) • *aaS? • "Universe of all economic services" • Can traditional "services" (law, accountancy, plumbing) be included in the logical Cloud?

  8. IDC Definitions (Sept 2008) Cloud Services = Consumer and Business products, Services, and solutions that are delivered and consumed in real-time over the Internet Cloud Computing = an emerging IT development, deployment and delivery model, enabling real-time delivery of products, services and solutions over the Internet (i.e., enabling cloud services) (From http://blogs.idc.com/ie/?p=190)

  9. Key cloud services attributes • Off-site, third-party provider • Accessed via Internet • Minimal/no IT skills needed to implement • Provisioning: • Self-service requesting • Near-real-time deployment • Dynamic and fine-grained scaling • Pricing model: • Fine-grained • Usage-based (at least available as an option) • User interface: browsers and their successors • System interface: Web services APIs • Shared resources/common versions (customization "around" the shared resources) According to research firm IDC

  10. Cloud business models • Consumption • Pay-per-use • Perpetual license • Renewable license / Subscription • Advertising funded • "Bits to objects" • Value-add for existing products • Build a user community

  11. What's out there right now – IaaS(Infrastructure as a Service) Amazon Infrastructure web services EC2 (Elastic Compute Cloud) - now with Windows (99.95% availability!) S3 (Simple Storage Service) SimpleDB SQS (Simple Queue Service) Payments and Billing On-demand workforce (Mechanical Turk) Search (Alexa) Fulfilment web service Rackspace Mosso JungleDisk SliceHost

  12. What's out there right now – PaaS(Platform as a Service) • Google Apps • Python only • BigTable • Heroku • Ruby on Rails hosted on EC2 • Force.com • Apex • Bungee Connect • Bungee Logic (a C-family language similar to C#) • Microsoft! • Azure - .NET hosted in MS datacentres

  13. What's out there right now – SaaS(Software as a Service)

  14. Microsoft Windows Azure The Azure™ Services Platform (Azure) is an internet-scale cloud services platform hosted in Microsoft data centers, which provides an operating system and a set of developer services that can be used individually or together.

  15. What problems will come up? 1. Regulatory Issues 2. Legislative Issues 3. Geopolitical 4. Security Vulnerabilities 5. Application Architecture 6. Hardware dependencies 7. Control over your servers 8. Cost of the cloud 9. If it Ain’t Broke Don’t Fix it

  16. A simple cloud services architecture today

  17. The Cloud Provider Continuum

  18. A Cloud Technology Reference Model Begin with the Basic Data Center

  19. A Cloud Technology Reference Model Add easy software access to: Elements - HW/SW/Network/Storage Settings, Installations, and Configurations Resources - Reservations from a pool of excess capacity in storage, computing, and network

  20. A Cloud Technology Reference Model Add some visibility: A Web of Metadata (What uses or contains what other things?) Lifecycle (when and how can things change?)

  21. A Cloud Technology Reference Model Add some real-world context: Governance (Who has authority / responsibility to change, and how?) Architecture Views (How are my concerns addressed?)

  22. A Cloud Technology Reference Model

  23. Infrastructure Clouds Start Here:

  24. “Cloud Servers” Try to Extend Infra:

  25. Cloud Platforms, As Perceived Today

  26. How Cloud Platforms Likely Will Evolve

  27. Filling in the Architecture Gap

  28. Easy/fast to deploy 83.6% Pay only for what you use 81.5% Low monthly payments 77.9% Less in-house IT staff, costs 77.5% Offers the latest functionality 77.0% Encourages more standard IT 73.3% Sharing systems/information simpler 67.2% 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% % responding 3, 4 or 5 Why Cloud Computing Is Very Important Q: Rate the benefits commonly ascribed to the 'cloud'/on-demand model (1=not important, 5=very important) Source: IDC Enterprise Panel, August 2008 n=244

  29. When to Bring Cloud Computing Into Plans?

  30. 26.2% IT Management Apps 39.3% 25.4% Collaborative Apps 46.3% 25.0% Personal Apps 36.1% 23.4% Current Business Apps 34.0% In 3 years 16.8% App Development/Deployment 25.9% 15.6% Server Capacity 28.7% 15.5% Storage Capacity 31.5% 0% 5% 10% 15% 20% 25% 30% 35% 40% 45% 50% % responding 4 or 5 Organizations Shifting Fast In Cloud Use Q: Currentand future level use of cloud services in your organization?(1=none, 5=widespread) Source: IDC Enterprise Panel, August 2008 n=244

  31. Cloud Computing Is “Crossing the Chasm” Source: The Chasm Group

  32. Security 88.5% Performance 88.1% Availability 84.8% Hard to integrate with 84.5% in-house IT Not enough ability to 83.3% customize Worried cloud will 81.1% cost more Bringing back in-house 80.3% may be difficult Not enough major 74.6% suppliers yet 65% 70% 75% 80% 85% 90% % responding 3, 4 or 5 Challenges Suppliers Are Tackling Q: Rate the challenges/issues of the 'cloud'/on-demand model (1=not significant, 5=very significant)

  33. Implications for IT Strategy & Organization

  34. Cloud will be part of an expanding portfolio of options Along with Traditional On-Premise and Next-gen On-Premise Implications for IT Strategy & Organization If organization is a “visionary” or “pragmatist”, it’s time now to start getting experience using Cloud offerings • Phase-in Cloud where the advantages tip the scales SOA – especially as an IT management approach – is essential to flexible and integratable IT services sourcing • Cloud services will allow some offload of SOA implementation to cloud services providers, and speed the Dynamic IT journey IT skills portfolio will continue to shift • Supplier Mgt, Web Svcs Dev/Integration, Bus. Process Insight • IT Ops “boiler room”, Application technical specialists

  35. When to use cloud services now? • Non-sensitive binary object storage (docs, pdfs, images etc) • use S3 or similar NOW! • Moving server hosting to the Cloud: business case needs developing • Management tools not mature • Not ready for Enterprise apps - but soon • Azure will be a key player for PaaS • Google, SalesForce(?) main competitors • Lots of niches • SaaS • When setting up a new business, use it now! Don't saddle your business with expensive, inflexible, rapidly depreciating assets you don't need!
