Typology based on data center purpose
In many cases, data centers are classified on the basis
of the underlying business model, e.g. housing and
collocation data centers, high-performance data centers,
and others.
Typology based on operator type
Suppliers of data centers often categorize data centers
by their operators, e.g. by industry sector (bank,
automobile, research, telecommunication, etc.) or in
terms of public authorities or private companies.
Another categorization distinguishes between enterprise
data centers and service data centers.
• Enterprise Data Centers (company-owned)
Data centers performing all IT services for a
company and belonging to that company (be it
in the form of an independent company or a
department).
• Service Data Centers (service providers)
Data centers specialized in providing data
center services for third parties. Typical
services are housing, hosting, collocation and
managed services, and exchange services for
the exchange of data.
Enterprise data centers are being increasingly offered as
service data centers (service providers) on the market,
particularly by public utility companies.
