IBM Buys Confluent, React2Shell, and Netflix on Aurora

In this episode of Ship It Weekly, Brian powers through a cold and digs into a very “infra grown-up” week in DevOps.

First up, IBM is buying Confluent for $11B. We talk about what that means if you’re on Confluent Cloud today, still running your own Kafka, or trying to choose between Confluent, MSK, and DIY. It’s part of a bigger pattern after IBM’s HashiCorp deal, and it has real implications for vendor concentration and “plan B” strategies.

Then we shift to React2Shell, a 10.0 RCE in React Server Components that’s already being exploited in the wild. Even if you never touch React, if you run platforms or Kubernetes for teams using Next.js or RSC, you’re on the hook for patching windows, WAF rules, and blast-radius thinking.

We also look at Netflix’s write-up on consolidating relational databases onto Aurora PostgreSQL, with big performance gains and cost savings. It’s a good excuse to step back and ask whether your own Postgres fleet still makes sense at the scale you’re at now.

In the lightning round, we hit OpenTofu 1.11’s new language features, practical Terraform “tips from the trenches,” Ghostty becoming a non-profit project, and two spec-driven dev tools (Spec Kit and OpenSpec) that show what sane AI-assisted development might look like.

For the human side, we close with “Your Brain on Incidents” and what high-stress outages actually do to people, plus a few concrete ideas for making on-call less brutal.

If you’re on a platform team, own SLOs, or you’re the person people ping when “something is wrong with prod,” this one should give you a mix of immediate to-dos and longer-term questions for your roadmap.
