Start Monitoring →Understanding SLA
A Service Level Agreement (SLA) is a formal commitment between a service provider and its clients regarding service quality, availability, and responsibilities.
The uptime percentage in an SLA represents the minimum guaranteed availability of a service over a specified period. For example, a 99.9% uptime commitment allows for approximately 43 minutes of downtime per month.
SLAs are crucial for:
- Setting clear expectations with customers
- Establishing accountability measures
- Defining compensation for service disruptions
- Planning maintenance windows
