SL-AIEOU

We've had some acronyms and abbreviations lately in tech and it's often difficult to keep up. Two of the below metrics are made up by me and might not be worthy of tracking.

SLA

What we agree to customers to expect from the service. Service Level Agreement.

SLI

How's the service actually performing. Service Level Indicator.

SLE

What's the error rates on the service. Service Level Errors.

SLO

What we agree internally as a team, to meet SLA. Service Level Objective.

SLU

What's the update frequency on the service. Service Level Updates.
