Since Linux is a free OS, most Linux hosting plans feature a lower cost. Many programs are also free. WordPress, Joomla, and other open-source programs were developed using Linux and are highly compatible with this operating system. Perl scripting is only available on Linux. Linux systems are renowned for their stability and get a lot of scrutiny for security from the open-source community.
Data centers use from 1 to 2 percent of world’s electricity. And only around a quarter of our current energy is renewable - there are still plenty types of conventional power used in order to get electricity. Examples of such ways are coal, oil, gas or nuclear energy. In turn, this means that the more servers there are, the more electricity they use. Because most our energy comes from conventional sources, servers increase our carbon footprint. In fact, a CLEER model simulation (a tool by Lawrence Berkeley National Laboratory and Northwestern University) published in Scientific American reveals an interesting fact. If all US companies would move their spreadsheet, email apps, customer management software and similar programs to the cloud, that would save enough a lot of energy. How much exactly? Enough to fully power the city of Los Angeles!
Rather than being hosted on one single instances of a physical server, hosting is delivered on a virtual partition which draws its resource, such as disk space, from an extensive network of underlying physical servers. If one server goes offline it will have no effect on availability, as the virtual servers will continue to pull resource from the remaining network of servers.
