Panel: Composable Platforms in the Real World: What Works, and What Really Doesn't

summary
Panelists compare real deployments: teams report a platform advertised as composable that actually blocks external images behind an undocumented admission policy (one ticket per ECR repo) and drove developers to abandon it; others ship working self‑service by exposing well‑documented Terraform modules as the primary interface instead of a UI; compliance is solved by clear accountability and RACI, not by removing composability; hopeful bets include WebAssembly modules (WASM) for minimal app payloads and using tools like Backstage, Argo and KubeRWO-type operators.
