Service Provider
Definition(s):
An organization supplying services to one or more internal customers or external customers.

Service Level Agreement (SLA)
Definition(s):
Represents a commitment between a service provider and one or more customers and addresses specific aspects of the service, such as responsibilities, details on the type of service, expected performance level (e.g., reliability, acceptable quality, and response times), and requirements for reporting, resolution, and termination.
Source: NIST NIST SP 800-47 Rev. 1 under service-level agreement
A formal agreement between a service provider (whether internal or external) and their client (whether internal or external), which covers the nature, quality, availability, scope and response of the service provider. The SLA should cover day- to-day situations and disaster situations, as the need for the service may vary in a disaster.

High Availability
Definition(s):
A failover feature to ensure availability during device or component interruptions.
Source: NIST NIST SP 800-113
An approach or design that minimizes or hides the effects of configuration item failure on the users of an IT service. High availability solutions are designed to achieve an agreed level of availability and make use of techniques such as fault tolerance, resilience and fast recovery to reduce the number of incidents, and the impact of incidents.

Cold Site
Definition(s):
A backup facility that has the necessary electrical and physical components of a computer facility, but does not have the computer equipment in place. The site is ready to receive the necessary replacement computer equipment in the event that the user has to move from their main computing location to an alternate site.
