If you’re thinking of running a serverless setup, congratulations! But…that means you’re running a distributed system. With all the benefits and simplicities that come with going serverless comes this tradeoff: You potentially also have some increases in complexity. Distributed systems are, by their nature, complex. With partitions, you’re communicating over a network that’s potentially unreliable and can’t be trusted. Which means that monitoring your application errors is going to be especially important.
