SLAs can be especially important for small start-ups. They are a way to develop respect among colleagues, give a common awareness of goals and offer professional rewards, while business struggles and sacrifices are provided to establish themselves in the industry. It`s a way for these companies to develop good habits right from the start. However, for critical services, customers should invest in third-party tools to automatically collect SLA performance data that provides an objective measure of performance. Where services are purchased by an external provider, there is a formal contractual agreement between the institution and the service provider. The SLA is used to provide the daily work details needed to support the contract. It is the starting point and basis for contract monitoring and management and often the trigger for corrective measures that can avoid a more serious contractual situation. Uptime is also a common metric, often used for data services such as shared hosting, virtual private servers, and dedicated servers. Usual agreements include the percentage of network availability, operating time, number of planned maintenance windows, etc. In addition to defining the services to be provided, the contract should also document how the services are to be monitored, including how the data is collected and disclosed, how often it is verified and who is involved in the verification. In the case of traditional SLAs, the service provider usually reimburses part of the service fee to the organization concerned.
