Availability Management

Availability Management is the practice of identifying, evaluating, implementing, and maintaining appropriate levels of IT service availability. The primary elements used in defining availability include:

ServiceabilityWhere a service is provided by a 3rd party organization, this is the expected availability of a component.
ReliabilityThe time for which a component can be expected to perform under specific conditions without failure.
RecoverabilityThe time it should take to restore a component back to its operational state after a failure.
MaintainabilityThe ease with which a component can be maintained, which can be both remedial or preventative.
ResilienceThe ability to withstand failure.



The purpose of Mainland's Availability Management services is to provide enhanced availability, integrity, and accessibility to valuable corporate data.

Considering all of the factors involved in producing a failsafe, highly available system or service can be a complicated task. Mainland Information Systems’ business is to assist organizations in realizing their IT service availability goals.
