| Test | Shared/API service | Dedicated managed service | Buyer-operated deployment |
|---|---|---|---|
| Variable demand | Check usage billing, rate limits and caching | Check minimum capacity and autoscaling | Check idle reserve and scaling operations |
| Performance | Measure observed latency and service variability | Verify reserved capacity and actual SLA | Own hardware/runtime tuning and failure recovery |
| Data controls | Review retention, location and subprocessors | Verify tenant isolation and support access | Own access, patching, logging and backups |
| Change control | Provider version policy matters | Contract model/runtime update process | Buyer owns update and regression burden |
| Exit | API replacement may require revalidation | Export and migration support are critical | Infrastructure portability is still work |
Modal and Baseten publicly describe different ways to serve custom workloads. Do not infer that all accounts receive the same isolation, availability or contractual service terms. Obtain the exact proposal.
