5 alternatives to 90DaysOfDevOps

michaelcade/90daysofdevops — This repository started out as a learning in public project for myself and has now become a structured learning map for many in the community. We have 3 years under our belt covering all things DevOps, including Principles, Processes, Tooli (29,857 stars, CC-BY-NC-4.0, infra, auth, search).

These are the closest projects in the JustClaw-It index that we serve licence-cleared code from, ranked by relevance and by our code-quality score (1–10, the mean over each repo's graded components: completeness, code quality, deployability, reusability, strategic value). JustClaw-It does not serve code from michaelcade/90daysofdevops itself (licence class: non-commercial), so these alternatives are the licence-cleared route.
