Running co-located servers for email & web (marketing services). We amortise the cost to $3k a month ($1k hardware, $2k colo/transit) over 5 years. Total CAPEX was $65k AUD 5 years ago including the warrenty. That gives us 3 Nodes with (192GB of Ram, 2x Hex core Xeons) and we have 7TB of Primary Storage w/ 12TB of secondary Storage. Due to the age the storage is all hard disk, but if we were to buy today it would be SSD Cached or even pure SSD for primary storage. VMWare manages the cluster and we currently have ~ 50 vm guests. As we have our own IP space, we have over 1500 IP address available. Connectivity is slow as it is hosted in Brisbane, Australia, but we get 500Mbit of connectivity which we can saturate easily without taxing the hardware. Cost and business need is the only things keeping this from being higher. Web activity is typically either highly dynamic but low frequency (custom web apps) or static, but high volume (image hosting for marketing emails). Since the payloads are high compared to most pages / APIs I really don't have numbers to compare as far as requests/second. We also tend to not be running the latest in the web stack, simply to keep maintenance down (we tend to use what ships with the base OS (Centos 7) and then add one or two packages if needed (PHP7)).
