2. Reuse existing architecture

Date: 2023-06-13

Status

Accepted

Context

Check the Children’s Barred List is a monolithic Rails application and should use a similar architecture to other monoliths, like Find a lost TRN.

Decision

We adopt the following ADRs wholesale from Find a Lost TRN, and agree to follow their decisions:

• 3. Use a Ruby on Rails monolith
• 4. Use Postgres
• 5. Use automated tooling to check for security vulnerabilities

Consequences

• We don't have to justify the same decisions
• We can still make adjustments by creating new ADRs down the line
• Knowledge transfer between teams is simpler
• Sharing code and modules is simpler
