Inevitable / Application infrastructure

Build the product.
Reuse the foundation.

Domain software needs more than intelligence. Users, organizations, permissions, billing, and operations are part of the product too. The application foundation gives those responsibilities a shared place to live.

Distinct products / A shared operating foundation
Different domain products span common application services Research, financial and transaction products keep distinct domain rules and interfaces. They build on shared identity and tenant scope, commercial operations, execution services and operating visibility, configured for each application.

In practice / Illustrative

Build the domain experience. Reuse the plumbing.

A research workspace and a transaction workflow have different rules. Common services can support both without forcing them into the same product or data boundary.

Domain logic + customer experience

The workflow, permissions, and operating rules are defined for this application.

A foundation shaped to the product.

Choose the services the application needs. Define its controls and verify the actual deployment rather than inheriting blanket security claims.

01 / Capabilities

The work beneath the workflow.

Reuse common application capabilities while keeping the product’s domain logic and user experience distinct.

Identity and access

Users, organizations, roles, and permissions connected to the application’s tenant context.

Commercial operations

Licensing, billing, usage, and administrative workflows shaped to the product’s agreement.

Product operations

Configuration, integrations, operational visibility, and the tools needed to support the application.

02 / The workflow

Define the controls.
Verify the deployment.

Security requirements belong to the actual application and deployment. Establish the data boundary, access model, review process, and operating responsibilities before expanding the implementation.

Data boundaries
Define tenant scope, sensitive data, retention, export, and the systems allowed to handle it.
Access boundaries
Define users, roles, service identities, permitted actions, and approval requirements.
Operating boundaries
Define logging, monitoring, recovery, support, and the evidence required to verify the agreed controls.

03 / In the stack

A foundation, not a one-size-fits-all product.

A research workspace, an underwriting application, and a transaction workflow have different interfaces and rules. They can share underlying services without sharing every capability or deployment choice. Choose what the product needs, and implement the remaining domain work around it.
