Modernise the platform without stopping the business.

Microservices, API-first, Cloud-native and Headless: four architectural principles that, together, replace one large monolithic application with independently deployable services connected by APIs, running on cloud infrastructure that scales automatically, with the front-end decoupled from the back-end. It matters because a monolith means one bug, one deploy or one traffic spike can affect the entire platform; MACH architecture contains that blast radius to one service.

No, and we'd advise against it. MACH transformations are run as a staged migration: components get pulled out of the monolith and rebuilt as independent services one at a time, so the business keeps operating on the existing system while the new architecture is built underneath it, rather than betting the whole platform on one big-bang rebuild.

The architecture assessment in step one gives an honest answer before any migration work starts. Signs it's worth it: deploys are slow and risky because everything ships together, the platform can't scale one part (like checkout during a sale) without scaling everything, or adding a new front-end means rebuilding logic that already exists elsewhere.

Because migration is staged and componentised, teams can generally keep shipping changes to parts of the platform that haven't been migrated yet, while newly migrated services get their own independent release cycle. Staging the work this way is specifically meant to avoid a long freeze on the rest of the business.

Either. We run migrated systems on Brova Cloud by default, with the monitoring, alerting and incident response a distributed system actually needs, because the same engineers who design microservices architecture understand what breaks in it. If you have an internal team that wants to take over operations, we hand off with documentation and can stay involved for the pieces that make sense.

It's most valuable once a platform has outgrown the point where one team can safely change one thing without affecting everything else, and that can happen well before “enterprise” scale. For a small platform with low complexity, a full MACH transformation is often more than the business needs yet; the architecture assessment will say so honestly rather than recommending it by default.
