systems and associated components, such astelecommunications and storage systems

Back up Power Supplies

Data Communication Connections

Environmental Controls(Air conditioning, Fire

suppression)

Security Devices



DATA CENTER DESIGN

Main Switch Board

Power Load Distribution Center

Server racks Precision Air Conditioner

Uninterruptible Power Supply

Backup Generator



Applications of Data center Business Continuity planning

Data Storage and Maintenance.

The data stored used for future references

Avoids cluttering of irrelevant data

Single entity dedicated



OUTSOURCING Relocation of a Business Process from one country to

another—typically an operational process, such asmanufacturing, or supporting processes, such asaccounting.



Benefits of Outsourcing• Helps in handling complicated workload

• Present task can be performed perfectly

IT-enabled Services

outsourcing

Company's outsourcing of computer or Internet

related work, such as programming, to othercompanies

BPO

Does not require much of technical skills
