Payfor the bandwidth and
server resources that youneed.
When your work is done then
turn the whole thingoff!

27. Benefits of cloud
1. ReducedInvestments and Proportional
Costs
– On-demand accessto pay-as-you-go computing
– reducing the need to prepare forprovisioning.
2. IncreasedAvailability andReliability

32. Technologies in DataCenter
1.Virtual Machines
• VM technology allows multiple virtual
machines to run on asingle physicalmachine.

etc.
Performance: Para-virtualization (e.g. Xen)is very close to raw physical performance!

35. 3.Remote Operation andManagement
4.HighAvailability
Data centers usually have redundant, uninterruptable power supplies,
cabling, and environmental control subsystems in anticipation of system
failure.
5.Computing Hardware
• rack mount form factor server design composed of standardizedrackswith
interconnects for power, network, and internalcooling
• support for different hardware processingarchitectures, suchasx86-
32bits, x86-64, andRISC
• apower-efficient multi-core CPUarchitecture that houseshundreds of
processingcoresin aspaceassmall asasingle unit of standardized racks
• redundant and swappable components, suchashard disks, power
supplies, network interfaces, and storage controllercards
