An ever-increasing proportion of a typical company’s infrastructure is moving to the cloud. More companies are shifting towards a micro-service approach. These paradigm shifts away from local to cloud-based means that you probably also have faced a situation where you had to pull data from somewhere or write data somewhere that is not your local computer.
On a small scale, there rarely are problems around that. If some extraction or writeback fails, you would typically notice that and would be able to remedy the mistake. But, as you move towards larger-scale operations and potentially hundreds of thousands of transactions, you don’t want to get screwed over by a temporary drop of internet-connection, too many concurrent writes, a temporarily unresponsive source system, or god knows what else.
