  • 2. Traditional Cost and Revenue Model
    Investment and revenue have to predicted:
    • static Infrastructure dimensioning
    • 3. architectures become monoliths
    Unpredictable success can invalidate all the reasoning done on cost partitioning:
    • churn rate increases when system is suffering;
    • 4. profit easily turns into loss due the scarse adaptability of the system
  • Cloud Elasticity
    cloud is impacting technology and business
  • 5. Cloud Cost and Revenue Model
    Investment and revenue are adaptable:
    • 'as needed' dynamic Infrastructure dimensioning
    • 6. architectures become modular and service oriented so components scale on business needs.
    Unpredictable success can:
    • allocate new resources to fulfill new/more requests;
    • 7. business easily remains profitable even on loss making markets as margins are maintained
  • SLA are one of the missing pieces of the puzzle to deliver services in an adaptive way.
    How
  • 8. Service Broker
    A Service Level must:
    • be part of the definition of a service;
    • 9. be configured by a service manager;
    • 10. declare the elasticity of a single target service
    • 11. describe how the system survives peak loads and adjusts
    Service Operations are becoming complex and a Service Broker must help govern where things are moving and why - to maintain business consistent.

    "You cannot think seriously to use the Cloud to support an adaptive business without thinking about SLAs."
