What is an SLA?

Service-level agreement

An SLA (service-level agreement) is the part of a contract in which a vendor commits to measurable levels of service, such as uptime and support response times, and states what the customer receives if those levels are missed.

What a streaming platform SLA covers

  • Availability: the percentage of time the service is up, measured monthly
  • Scope: which components count, such as playback, sign-in, the CMS and the API
  • Support: how quickly the vendor responds, by severity of the problem
  • Resolution or escalation targets for critical incidents
  • Remedies: service credits when a target is missed
  • Exclusions: planned maintenance, third-party failures and events outside the vendor's control

What uptime percentages mean

  • 99.5%: up to about 3.6 hours of downtime in a 30-day month
  • 99.9%: about 43 minutes
  • 99.95%: about 22 minutes
  • 99.99%: about 4 minutes

How to read an SLA

Look at what is measured and how. Availability of a status page is not the same as viewers being able to play video. Check whether maintenance windows are excluded, whether you must claim a credit yourself, and whether the credit is capped at a fraction of the monthly fee.

An SLA compensates; it does not prevent. For a live event that cannot be repeated, the vendor's architecture, monitoring and event support matter more than the credit you would receive afterward.

What does SLA stand for?

SLA stands for service-level agreement.

Is a higher uptime percentage always worth paying for?

Only if downtime costs you more than the difference in price. A service with live events or advertising commitments has more at stake than a small on-demand library.

What is a service credit?

A discount on a future invoice, given when the vendor misses a committed level. It is usually a percentage of that month's fee.
