# Build Infrastructure

STO uses [CI build infrastructures](/continuous-integration/use-harness-ci/use-harness-ci/set-up-build-infrastructure/which-build-infrastructure-is-right-for-me.md) to orchestrate scans and ingest issues. The following table shows the supported operating systems and architectures for each build infrastructure option.
