Have a discussion frame for monolith vs services.
A relevant architecture depends on the business problem, organisational maturity, volume, integrations, security, skills, budget and evolution prospects. The best stack remains relevant after the demo is over.
Styles, not dogmas
| Modular monolith | Microservices |
|---|---|
| MVP, small team, still manageable complexity | Strongly separated domains, multiple teams |
| Simpler operations, simpler transactions | Independent deploys, failure isolation |
| Risk: entanglement if modules are not held | High cost of operations and observability |
APIs and coexistence
Many systems must talk to an ERP, CRM, partner or existing BI. Connecting often beats recreating. API-first makes sense as soon as there are several consumers — web, mobile, partners.

Evolve without rewriting everything
Audit, API encapsulation, modularisation, strangler pattern when relevant: a full rewrite is not always the best decision. Modern systems often have to coexist with historical ones.
