SLA is an abbreviation of Service Level Agreement, which is an agreement on the level of service (definition, scope, content, achievement goals, etc.) established between the provider of the service and its users. This is a statement to the extent that the service provider can guarantee the quality to the contractor.
SLAs are often used mainly for communication services, cloud services, rental servers, etc. We define service definition and guarantee items such as communication speed and upper limit of use stop time, and if the service quality falls below the guarantee value of SLA, reduction of charge will be performed.
