What's infrastructure?

Devices providing processing, interconection, storage and other fundamental computer resources

Evolution

  1. Physical hardware
  2. Virtual machines
  3. Infrastructure in the cloud

Traditional infrastructure

  • Equipment purchase
  • Rack mount
  • Physical connection to the network
  • "Manual" OS installation and configuration
  • Storage provided by NAS or SAN
  • Static infrastructure
  • Same configurations for years
  • Users with no direct access

Virtual Machines

  • Several VMs running on a physical machine
  • VMs managed by the hypervisor
  • VMs connected through virtual networks
  • Without significant changes in storage
  • Similar management to traditional infrastructure

Cloud Infrastructure

  • Machines virtualization
  • Network virtualization
  • Storage virtualization
  • Resource pooling
  • Dynamic infrastructure
  • Automatic configuration
  • The user manages his or her own infrastructure
