In comparison with shared servers, single tenancy analogues are used by one person only, which is why they are called dedicated servers. Although they are only gaining popularity among web-masters, they appeared more than 30 years ago, having rich history.
The first Simple Desktop-like server machine was introduced in 1980’s, and it was a bunch of bare metals and simple desktop placed inside small rooms of companies. Dedicated servers’ grandfather featured 256Mhz CPU and a 2 Gb disk.
In 1990’s, this version was replaced by Rack Mountable Web Server, because the demand for web hosting services increased dramatically. This server had 450Mhz Intel CPU, 256Mb RAM, and a 24X CDROM.
The first milestone of dedicated server development was in 1998, when the first Google server with 256MB RAM and dual CPUs of 200 Mhz was introduced.
Starting from 2000’s the physical dimensions of this technology decreased dramatically: newly introduced blade servers were the size of a palm. This period is also characterized by the implementation of distributed computing technology, virtualization and cloud computing.
The recent turning point is the introduction of so-called Unified Computing System technology that serves to optimize the resources of data-center and dedicated servers, unifying them into a pool of network resources and storage. This technology offers better speed, agility and reliability.
