Remove reliability intercorrelations, so for example that your cart api and payment gateway is up and collecting orders no matter to what happens to the front-end services. But then for perfect decorrelation you'd also need independent databases behind the microservices, and queues between them for horizontal communication,and few are actually going all in with that, and so fall in the 95% where they go trough te motion and the effort of splitting microservices,but reap no actual benefit from it.
