| Time to production |
Months of architecture, infra, backend and UI work before a usable agent. |
Fast to launch, but integrations, data grounding, and security approvals can still take weeks/months. |
Scaffold in under an hour — once kickoff inputs and approvals are in place. First tailored enterprise agent in 2–8 weeks (scope/integrations). |
| Data ownership |
Full control, but your team owns everything end-to-end. |
Data and conversations typically live in the vendor’s environment (with their backup/logging policies). |
All data and infra in your AWS account/VPC; you pay AWS directly. |
| Control over data & access |
You can control IAM, retention, audit logs, and governance—if you build and maintain it. |
Access controls and retention are constrained by the vendor platform; you can’t enforce everything the same way as “in-account.” |
Your IAM, your retention rules, your audit trails—because it runs inside your AWS account/VPC. |
| Customisation & extensibility |
As flexible as your budget and team can support. |
Limited to what the vendor exposes; deep changes are hard or impossible. |
Built to add new agents, tools, workflows and containers on a reusable scaffold. |
| Long-term maintenance |
You own upgrades, patches, libraries, observability, and on-call—often requiring specialists over time. |
Vendor maintains their platform, but you’re dependent on their roadmap and constraints. |
Foundation is standardised and reusable; platform updates and bug fixes are provided as part of the product, while your data stays in your account. |
| Team turnover risk |
New teams often need significant time to learn the original architecture and decisions. |
Less infra ownership, but switching later can mean reworking integrations and workflows. |
Consistent scaffold + conventions makes onboarding and handover easier than a one-off custom build. |
| Multi-model support |
Requires you to design and maintain your own abstraction layer. |
Often tied to one stack or a small set of models. |
Multi-model by design: use Bedrock and other APIs from a single runtime. |
