Google Professional-Cloud-DevOps-Engineer Question Answer

You are responsible for the reliability of a custom-built, distributed file storage service that your company uses internally. This service handles thousands of file uploads and downloads daily. You need to define a service level indicator (SLI) to measure the reliability of your service usage and configure alerts to be notified of potential issues. Which SLI should you use to measure the reliability of the service?

Average request latency of API calls (e.g. get, put, list)

Average size of objects stored in your service

Ratio of successful API calls to the total number of attempted API calls

Number of successful file uploads and downloads per minute
