Basics of Cloud Computing

• Lets consider the a simple website architecture
• Cloud Services Provider (CSP):
  • These are organizations who offer cloud based services
• Cloud Services Consumer:
  • These are organizations/individuals who use cloud based services offered by CSP
• How the infra is managed in the cloud
• High Availability:
  • Following are most common issues
    • A network outage
    • An application failure
    • A System outage
    • A power outage
  • CSP offer Service Level Agreement (SLA) that guarentees a certain level of availability as a percentage.
• Scalability, elasticity:
  • Scalbility and elasticiy allow you to increase the vm’s manually or automatically depending on usage pattern.
  • There are two variations of scaling
    • Vertical Scaling (Scaling up): Increase resources to the system (Workload)
    • Horizontal Scaling (Scaling out): Increase number of Systems (Workload)
  • Elasticity refers to automatically scaling out and scaling in
• Fault Tolerance and disaster recovery:
• Pay as you go: Every service in cloud is metered and you pay depending on your usage.
