On-Premises
Servers
• Bring your own
machines, connectivity,
software, etc.
• Complete control
• Complete responsibility
• Static capabilities
• Upfront capital costs for
the infrastructure
Hosted
Servers
• Renting machines,
connectivity, software
• Less control
• Fewer responsibilities
• Lower capital costs
• More flexible
• Pay for fixed capacity,
even if idle
Cloud
Platform
• Shared, multi-tenant
infrastructure
• Virtualized & dynamic
• Scalable & available
• Abstracted from the
infrastructure
• Higher-level services
• Pay as you go
