[Read as Markdown](https://cohesivity.ai/blog/ai-backend-infrastructure-for-startups.md) Agent Product State Controls An AI startup should choose backend infrastructure based on who will operate it, which services the product needs, and what the team must control directly. A solo founder delegating setup to coding agents has a different constraint from a platform team with cloud and compliance experience. Company size is a weak shortcut. Operator capability and product requirements give a clearer answer. ## Start with the operator Ask who will perform these tasks during the next year: - create and configure a new environment; - rotate credentials and investigate access; - apply and recover database migrations; - diagnose a failed deployment or provider outage; - enforce quotas and approve spend; - export data and remove a service. If the answer is "the coding agent," every task needs a callable contract, scoped identity, and structured result. If the answer is a platform engineer, direct cloud control may be a benefit rather than overhead. The [agent-operable backend guide](https://cohesivity.ai/blog/build-a-backend-ai-coding-agents-can-operate) gives a lifecycle test for that distinction. ## Three operating models ### Direct cloud AWS, Google Cloud, and Azure expose broad service catalogs and detailed control over identity, networking, regions, and deployment. This path fits teams with specific architecture, compliance, private-networking, or data-location requirements and the people to operate them. The cost is responsibility. The team owns service selection, infrastructure code, access policy, observability, upgrades, and incident response. Cloud APIs are highly automatable, but granting an agent broad cloud credentials is not a sensible substitute for platform engineering. ### Traditional backend platform Platforms such as Supabase and Firebase package database, authentication, storage, functions, and related services. Both now expose official MCP tooling for coding agents. Supabase documents project scoping and read-only operation in its [MCP guide](https://supabase.com/docs/guides/ai-tools/mcp). Firebase documents project and service actions in its [MCP server guide](https://firebase.google.com/docs/ai-assistance/mcp-server). This path fits teams that want those platforms' data models and are comfortable authenticating agents into an owned organization or project. ### Agent-native infrastructure Agent-native infrastructure makes an account-free or low-friction build path a product requirement. Cohesivity lets a coding agent start an ephemeral tenant and provision supported services before a human chooses to claim it. It keeps upstream provider credentials behind one control plane. This fits fast greenfield builds whose required services are in the platform. It does not fit teams that need direct upstream accounts, on-premises deployment, or a provider Cohesivity does not support. ## Compare responsibilities, not setup time | Decision | Direct cloud | Traditional BaaS | Agent-native infrastructure | | -------------- | ---------------------------------------------------------- | --------------------------------------- | ------------------------------------------------------------- | | Service design | Team chooses and connects services | Platform supplies an integrated product | Agent requests supported services through one project | | First project | Account, organization, IAM, and service setup | Account and platform project | Ephemeral bootstrap can precede human claim | | Credentials | Team manages provider credentials | Team owns platform credentials | Platform keeps upstream credentials server-side | | Operations | Team owns most layers | Shared with one backend platform | Shared with agent-facing control plane and upstream providers | | Portability | Highest potential, depending on design | Depends on platform APIs and data model | Depends on Cohesivity contracts and underlying services | | Best fit | Dedicated infrastructure capability or strict requirements | Product matches the platform | Agent-driven, multi-service greenfield build | Do not attach fake hour estimates to the rows. Setup time varies with existing accounts, policy, and team experience. Run one representative setup and record the real handoffs. ## Check the exit before entering Before choosing any managed backend, document: 1. How data and files are exported. 2. Which application APIs are provider-specific. 3. Whether identity records and password credentials can migrate. 4. How custom domains and deployment state move. 5. Which logs and audit records remain available after cancellation. A startup can accept lock-in. It should know which rewrite or migration that choice buys later. ## Budget per completed product workflow Model tokens are only one cost. Include tool calls, database and storage, execution time, network, failed runs, retries, and idle environments. The [agent infrastructure cost guide](https://cohesivity.ai/blog/ai-agent-infrastructure-costs) gives a traceable calculation. Price the user outcome that pays for the system. A support agent should be measured per resolved ticket, while a builder product might use a tested deployment. ## Set a reevaluation trigger Choose a platform for the next operating phase and name the event that changes the decision. Examples include a regulated customer, a new data-location requirement, a dedicated platform hire, a service the current platform lacks, or a measured cost threshold.
