## Take-aways for your architecture

1. **Use DACA for the plumbing you used to write by hand.** You get distributed state, pub/sub, standardised function calls, and cross-agent chat out-of-the-box, which eliminates most of the “custom glue”.  
2. **Budget time for compliance & security.** Map your regulatory obligations early and embed policy engines and audit sinks alongside Dapr sidecars.  
3. **Plan an edge tier if latency is existential.** DACA scales to many nodes, but you may still need micro-clusters or WebAssembly-based inferencing in the device.  
4. **Adopt FinOps tooling.** Free tiers are great for class projects; enterprise roll-outs need continuous cost observability.  
5. **Keep your protocols vanilla.** Sticking to A2A and MCP where possible cushions you from future cloud churn.

With these additions, DACA becomes not just a clever pattern but the *launchpad* for a genuinely agent-native cloud stack.
