When it comes to enterprise-level databases, there are several options available in the market, but PostgreSQL stands out as one of the most popular and reliable choices. PostgreSQL supports sharding, which allows data to be distributed across multiple servers, making it ideal for high-traffic websites and applications.

The carbon footprint of a large rack mounted server is order-of-magnitude a ton of carbon a year. A rough guide if you don’t have any better data is that with no traffic to a system it will be 10% utilization and use 30% of peak power, 25% utilization uses 50% of peak power, and at 50% utilization it uses 75% of peak power.

Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). This is one of the main reasons why content delivery networks (CDNs) exist: They place servers physically closer to the end user in order to reduce latency, and thus delay, as much as possible.
