Cloud Computing - Is It Right For You?

  1. 1. An Introduction to Cloud Computing -Is It Right For You?<br />Carlos Oliveira<br />13th December 2010<br />
  2. 2. What Is Cloud Computing?<br />Making Computing resources available as a utility service, <br />Just like the National Electricity Grid<br />Available through a well-defined interface<br />Available everywhere and for many devices<br />Power output scales to demand<br />No need to know about how or where it’s generated<br />Reliable<br />Low capital expenditure for consumers<br />Pay for what you use<br />
  3. 3. On-Premise Computing<br />Requires hardware, space, electricity, cooling<br />Requires managing OS, applications and updates<br />Software Licensing<br />Difficult to scale<br />Too much or too little capacity<br />High upfront capital costs<br />You have complete control and responsibility<br />
  4. 4. Managing Demand<br />Forecast demand<br />IT Capacity<br />Potential business loss<br />Compute capacity<br />Over capacity<br />Under capacity<br />Wasted capacity<br />Entry<br />barrier<br />Time<br />
  5. 5. Demand Burst<br />IT Demand<br />How do we deal with this?<br />Ticket sales open<br />Ticket sales open<br />Time<br />Concert ticket web site<br />
  6. 6. Three Types of Cloud Services<br />“IaaS”<br />“PaaS”<br />“SaaS”<br />Infrastructure as a Service<br />Platform as a Service<br />Software as a Service<br />migrate to it<br />build on it<br />consume it<br />6<br />
  7. 7. Private<br />(On-Premise)<br />Infrastructure<br />(as a Service)<br />Platform<br />(as a Service)<br />Each Brings a Different Level of Control<br />You manage<br />Applications<br />Applications<br />Applications<br />You manage<br />Runtimes<br />Runtimes<br />Runtimes<br />Security & Integration<br />Security & Integration<br />Security & Integration<br />Databases<br />Databases<br />Databases<br />You manage<br />Servers<br />Servers<br />Servers<br />Virtualization<br />Virtualization<br />Virtualization<br />Server HW<br />Server HW<br />Server HW<br />Storage<br />Storage<br />Storage<br />Networking<br />Networking<br />Networking<br />
  8. 8. Many Players in the Game<br />To name a few<br />SaaS: Microsoft, Salesforce, Zimra, Oracle, Cisco, Google Apps<br />PaaS: Microsoft, Force.com, Spring Source, Google App Engine<br />IaaS: Amazon, IBM, VMware, Microsoft <br />Expect change, the cloud is still in it’s infancy<br />In the future expect to see large vendors offering all of the services<br />
  9. 9. What We Get With SaaS <br />Lower capital expenditure<br />Fixed operational costs<br />Scalability<br />Reclaimed office space<br />Innovation<br />Lower carbon footprint<br />Agility<br />
  10. 10. What To Watch<br />You are relinquishing control and responsibility to the vendor by moving the service to the Cloud<br />For this to be a valid business proposition you must trust the vendor to deliver what they say they will<br />Financial penalties for failing to meet SLA are normally equated to service credits<br />Many solutions appear attractive because of the bottom line pay/user price<br />They may exceed or fall short of your business requirements<br />
  11. 11. What We Get With PaaS<br />An elastic computing platform<br />Connect from anywhere, with any device<br />Low barrier costs to deploying new applications<br />Rapid provisioning<br />Pay as you go<br />Operational costs directly related to profit<br />A marketplace through which to sell services<br />Customers continue to pay as long as they use theservices<br />No chance of licence abuse <br />
  12. 12. Manages Bursts in Demand<br />Scale prior todemand<br />IT Demand<br />On-demand compute capacity<br />Compute Capacity<br />Ticket sales open<br />Ticket sales open<br />Time<br />Concert ticket website<br />
  13. 13. What to Watch<br />Check your security policies can be satisfied by the Cloud provider<br />Does the SLA meet availability requirements?<br />Don’t just port an existing app that have been sitting within your security perimeter<br />Make sure it has been engineered for Internet security <br />Follow Security Development Lifecycle (SDL) best practices<br />
  14. 14. “Cloud Computing and Sustainability”<br />30-90% FEWER CO2 EMISSIONS*<br />MORE EFFICIENT IT<br />Dynamic provisioning <br />Multi-tenancy<br />Server utilization <br />Data center design<br />Reduced energy bills <br />Fewer servers<br />Less datacenter space<br />Less expensive<br />ONLINE SERVICES SUPPORTS OUR AMBITION TO BE ENVIRONMENTALLY CONSCIOUS BY ENABLING US TO OPERATE WITH FEWER SERVERS AND LESS ENERGY CONSUMPTION, ELIMINATING APPROXIMATELY 800 METRIC TONS OF CARBON DIOXIDE A YEAR,” <br />-PIA HOFSTEDT, DIRECTOR OF IT, SCANDIC<br />* Cloud Computing and Sustainability: The Environmental Benefits of Moving to the Cloud; www.microsoft.com/environment/cloud.aspx<br />
  15. 15. Companies Are Embracing Cloud<br />15<br />
  16. 16. Reframe your thinking<br />Use the best of breed<br />Stop thinking about applicationsrunning on servers<br />CRM<br />Ordering<br />Invoicing<br />Invoicing<br />Ordering<br />CRM<br />Think of them as pay on demandservices<br />Communications<br />Business forecasting<br />Rapidly add and try new functionality<br />Social Networking<br />
  17. 17. Should YouMove To The Cloud?<br />Can you afford not to?<br />“By 2012, 80% of Fortune 1000 enterprises will be using some cloud computing services, 20% of businesses will own no IT assets.”<br />“The bottom line: Early adopters are finding serious benefits, meaning that cloud computing is real and warrants your scrutiny as a new set of platforms for business applications.” <br />
  18. 18. So...What Is Cloud Computing?<br />It’s a utility,<br />providing us with:<br /><ul><li>New ways of working
  19. 19. Reduced IT costs
  20. 20. New opportunities</li></li></ul><li>Thanks for listening!<br />web: http://www.shapingcloud.com<br />email: carlos@shapingcloud.com<br />twitter: shapingcloud<br />
