I’ve come up with a great way to replicate the distributed monolith architecture but in a regular monolith!

const call = async (fn, ...args) => {
  await sleep((Math.random() ** 7) * 2000);
  if (Math.random() < 0.001) throw new Exception();
  return fn(...args);
};

The game is you are no longer allowed to call any function directly and you have to do it through call, yet have to find a way to make your software resilient.
