Episode notes
Platform Engineering As A Unifying Domain
- Platform engineering unifies disciplines like SRE, security, and UX to reduce developer obstacles.
- Combining defaults and cross-discipline collaboration prevents fragmented “ambassador” models.
Why Platform Teams Emerged
- Platform teams rose because hiring more engineers isn't a sustainable productivity fix.
- Investing in shared platform work empowers engineers and reduces duplicated effort.
Experiment And Protect Psychological Safety
- Treat SRE and platform ideas as experiments and validate them in your context.
- Encourage psychological safety so teams can take risks and learn from failures.
