Language of cloud computing

High availability

• This feature is core to the cloud
• You dont own the hardware
• You can add more servers with a click
• If a hardware fails, you can instantantly replace it
• Use clusters to ensure high availability

Reliability

• AKA Fault tolerance or Disaster recovery
• Resilience
  • The ability of a system to recover from failures and continue to function
• Deploy in multiple locations
  • Global-scale computing
  • Protects against regional failure/disaster
• No single point of failure
  • Resources in multiple locations
  • If one system goes down, the other picks up the load

Scalability

• Automatically adjust resources to meet demand
• Dont overpay for services
  • Automatically reduce resources when demand drops
• Horizontal vs Vertical scaling
  • Horizontal = adding additional VMs/containers
    • ”Scaling out”
  • Vertical = increasing power of existing VMs
    • ”Scaling up”

Predictability

• Predictable performance and costs
• Performance
  • Consistent experience for customers regardless of traffic
  • Autoscaling, load balancing, and high availability provide consistent experience
• Costs
  • No unexpected surprises
  • Track and forecast resource usage in real time
  • Analytics provide patterns/trends to optimise usage

Management

• Security
  • Full control of the security of your cloud environment.
  • Patches, maintenance, network control and more
• Governance
  • Standardized environments
  • Regulatory requirements
  • Audit for compliance
• Manageability
  • Management of the cloud
    • Autoscaling
    • Monitoring
    • Template-based deployments
  • Management in the cloud
    • Portal
    • CLI
    • APIs
