An operational level agreement (OLA) defines the interdependent relationships to support a service level agreement (SLA).  The agreement outlines the responsibilities of each internal support group to the other support groups, including the process and timeline for the delivery of their services. The objective of the OLA is to present a clear, concise and measurable description of the service provider`s internal support relationships. Service level agreements can include many service performance metrics with corresponding service level objectives. A common case in IT service management is a call center or service center. The measures that are typically agreed upon in these cases include: A Web Service Level Agreement (WSLA) is a standard for monitoring compliance with Web services through service level agreements. It allows authors to specify the performance metrics associated with a Web service application, the desired performance goals, and the actions to take when performance is not achieved. The result that the customer receives through the service provided is at the center of the service level agreement. SLAs typically include many components, from defining services to terminating contracts.  To ensure that SLAs are consistently respected, these agreements are often designed with specific dividing lines in mind, and stakeholders need to meet regularly to create an open communication forum. The rewards and penalties that apply to the supplier are often indicated. Most SLAs also leave room for regular (annual) reviews to make changes.

It can be a legally binding formal or informal “contract” (e.B. internal departmental relations). The agreement can include separate organizations or different teams within an organization. Contracts between the service provider and other third parties are often (wrongly) called SLAs – since the level of service has been set by the (primary) customer, there can be no “agreement” between third parties; these agreements are simply “contracts”. However, operational-level agreements or AROs can be used by internal groups to support SLAs. If an aspect of a service has not been agreed with the customer, it is not an “SLA”.
If the underlying AOLA(s) are not there, it is often very difficult for companies to go back and make agreements between support teams to provide the SLA. The OLA(s) should be considered as a basis for best practices and joint agreements. Service level agreements are also defined at different levels: these agreements replace previous versions. Authors who signed agreement forms before January 1, 2014 may continue to archive their articles as described in Wiley`s self-archiving policy. A service level agreement (SLA) is an obligation between a service provider and a customer. Certain aspects of the Service – quality, availability, responsibilities – are agreed between the Service Provider and the User of the Service.  The most common element of an SLA is that the services must be provided to the customer as agreed in the contract. For example, Internet service providers and telecommunications companies typically include service level agreements in the terms of their contracts with customers to define service levels sold in plain language. In this case, the SLA usually has a technical definition in mean time between failures (MTBF), mean repair time or mean recovery time (MTTR); Identify which party is responsible for reporting errors or paying fees; Responsibility for different data rates; throughput; tremors; or similar measurable details.

The underlying advantage of cloud computing lies in the sharing of resources supported by the underlying nature of a shared infrastructure environment. Therefore, SLAs cover the entire cloud and are offered by service providers as a service-based agreement rather than as a customer-based agreement. .
