Data Center
A
data center is an application development
implementation
work product consisting of
a facility housing one or more production environments (e.g.,
server computers, network connectivity devices, databases,
applications) that is used by the operations organization to
perform data processing for user organizations.
The typical objectives of a data center are to:
- Support numerous users of common applications and
databases.
The typical benefits of a data center are:
- Users need not have extensive computing resources on
their personal desktops.
- Operational costs are diminished due to economies of
scale.
- Data centers provide increased quality factors such as
operational availability, reliability, robustness,
scalability, security.
- Users have access to expensive capabilities.
- Users need not perform their own system and network
administration.
- Organizations can better enforce standardization.
The typical contents of a data center include:
- Server computers.
- Operations consoles.
- Networks including cabling and network connectivity
devices.
- Applications.
- Databases.
- Mass storage devices:
- Tape drives.
- Hard drives.
- Tape libraries.
- Disk libraries.
- Peripheral equipment including printers.
- Support systems including:
- Normal electrical and uninterruptible power supplies
(UPS).
- Air-conditioning.
- Fire suppression equipment.
- Physical security devices.
The typical stakeholders of a data center include:
- Producers:
- Evaluators:
- Approvers:
- Maintainers:
- Users:
A data center is typically produced during the following
phases:
A data center can typically be started if the following
preconditions hold:
- The
data center architecture document is relatively complete
and stable.
- Funding for facilities and capital expendatures
exist.
- Approval has been granted.
- Adequate staffing exists.
The typical inputs to a data center include:
- Work Products:
- Stakeholders:
A data center is typically constrained by the following
conventions:
- The development organization’s data center.
- The operation organization’s data center.
- A back-up data center.
