To borrow Henry Ford’s alleged words, it would be great at designing faster horses, if asked. But I don’t think an AI could ever design an automobile without having seen one first—or without having a human say “ Put a steam engine on a tricycle.” AI would have trouble creating anything new because AI can’t want anything—new or old.

However, with today’s highly connected digital world, monitoring use cases expand to the services, processes, hosts, logs, networks, and of course, end-users that access these applications — including a company’s customers and employees. Mobile apps, websites, and business applications are typical use cases for monitoring.

With these requirements in mind, and a willingness to question the status quo, a small group of distributed systems experts came together and designed a horizontally scalable distributed database that would scale out for both reads and writes to meet the long-term needs of our business. This was the genesis of the Amazon Dynamo database.

Before designing a better system for detecting partial failures, the authors set about understanding their nature and causes through a study of five software systems (ZooKeeper, Cassandra, HDFS, Apache, and Mesos).

The idea behind these UI decisions is that a badge would let a user know quickly if a site is loading slowly due to a problem on their end (network issue, internet is down, etc) or if the website is known to be built in a way that loads slowly. Most stemmed from Google exercising too much power with this move.

This can be changed later using the pg_checksums utility, but that will be a painful exercise on a big database.
