Hi Product Hunt — I’m Susumu, creator of TenkaCloud. I built it because most cloud training stops at a working template or a scripted lab. Running a real multi-team exercise is a different problem: each team needs an isolated environment, safe access, repeatable provisioning, scoring, hints, fault injection, a leaderboard, and reliable cleanup. TenkaCloud brings those pieces together as Apache-2.0 OSS. It supports two formats: • Challenge: self-paced, flag-based drills • Battle: live exercises scored continuously from the actual state of each team’s service The first quest takes about three minutes and needs no signup. After that, you can try local Docker mode or deploy TenkaCloud Lite into your own AWS account. I also published the full authoring and operating path as a free English book: https://leanpub.com/build-your-o... I’d especially value feedback from SRE, platform engineering, cloud security, and enablement teams: what scenario would you want to run as a competition?
