One app with clean seams, split only when the evidence says to
Skip the cost and complexity of microservices until there's a real reason to pay it.
One deployable now, splittable later
Contract-shaped seams at external boundaries
The challenge
Teams reach for microservices by default and start paying the price: network calls, partial failures, and harder deployment and debugging, long before they have a reason to.
How we solved it
We start with one app, but with clean seams built in. The parts that talk to outside systems sit behind connectors with a clear boundary. Everything else ships as one thing. The seams are there so a piece can be split off later, but only when there's a real reason to.
The result
One thing to deploy and debug now, with the option to break pieces off later. The split becomes a decision you make on evidence, not a stance you take on day one.
