  • 1. An Introduction to Cloud Computing -Is It Right For You?
    Carlos Oliveira
    13th December 2010
  • 2. What Is Cloud Computing?
    Making Computing resources available as a utility service,
    Just like the National Electricity Grid
    Available through a well-defined interface
    Available everywhere and for many devices
    Power output scales to demand
    No need to know about how or where it’s generated
    Reliable
    Low capital expenditure for consumers
    Pay for what you use
  • 3. On-Premise Computing
    Requires hardware, space, electricity, cooling
    Requires managing OS, applications and updates
    Software Licensing
    Difficult to scale
    Too much or too little capacity
    High upfront capital costs
    You have complete control and responsibility
  • 4. Managing Demand
    Forecast demand
    IT Capacity
    Potential business loss
    Compute capacity
    Over capacity
    Under capacity
    Wasted capacity
    Entry
    barrier
    Time
  • 5. Demand Burst

    How do we deal with this?

  • 6. Three Types of Cloud Services
    “IaaS”
    “PaaS”
    “SaaS”
    Infrastructure as a Service
    Platform as a Service
    Software as a Service
    migrate to it
    build on it
    consume it

  • 8. Many Players in the Game
    To name a few
    SaaS: Microsoft, Salesforce, Zimra, Oracle, Cisco, Google Apps
    PaaS: Microsoft, Force.com, Spring Source, Google App Engine
    IaaS: Amazon, IBM, VMware, Microsoft
    Expect change, the cloud is still in it’s infancy
    In the future expect to see large vendors offering all of the services
  • 9. What We Get With SaaS
    Lower capital expenditure
    Fixed operational costs
    Scalability
    Reclaimed office space
    Innovation
    Lower carbon footprint
    Agility
  • 10. What To Watch
    You are relinquishing control and responsibility to the vendor by moving the service to the Cloud
    For this to be a valid business proposition you must trust the vendor to deliver what they say they will
    Financial penalties for failing to meet SLA are normally equated to service credits
    Many solutions appear attractive because of the bottom line pay/user price
    They may exceed or fall short of your business requirements
  • 11. What We Get With PaaS
    An elastic computing platform
    Connect from anywhere, with any device
    Low barrier costs to deploying new applications
    Rapid provisioning
    Pay as you go
    Operational costs directly related to profit
    A marketplace through which to sell services
    Customers continue to pay as long as they use theservices
    No chance of licence abuse

  • 13. What to Watch
    Check your security policies can be satisfied by the Cloud provider
    Does the SLA meet availability requirements?
    Don’t just port an existing app that have been sitting within your security perimeter
    Make sure it has been engineered for Internet security
    Follow Security Development Lifecycle (SDL) best practices
  • 14. “Cloud Computing and Sustainability”
    30-90% FEWER CO2 EMISSIONS*
    MORE EFFICIENT IT
    Dynamic provisioning
    Multi-tenancy
    Server utilization
    Data center design
    Reduced energy bills
    Fewer servers
    Less datacenter space
    Less expensive
    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,”
    -PIA HOFSTEDT, DIRECTOR OF IT, SCANDIC

  • 17. Should YouMove To The Cloud?
    Can you afford not to?
    “By 2012, 80% of Fortune 1000 enterprises will be using some cloud computing services, 20% of businesses will own no IT assets.”
    “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.”
  • 18. So...What Is Cloud Computing?
    It’s a utility,
    providing us with:
    • New ways of working
    • 19. Reduced IT costs
    • 20. New opportunities
