Greenplum Database is an open-source , hardware-agnostic MPP database for analytics, based on PostgreSQL and developed by Pivotal who was later acquired by VMware. In this blog post, we explain what Greenplum is, and break down the Greenplum architecture, advantages, major use cases, and how to get started. What Exactly is Greenplum?

A trip from a device in London to a server in New York has a theoretical best-case speed of 28ms over fibre, but this makes lots of very optimistic assumptions. This is why serving your content from a CDN is so important: even in the internet age, being geographically closer to your customers is advantageous. Expect closer to 75ms.
