So how do you get very cheap servers th­ese days?

This is one of the most fre­quently asked ques­tions (FAQs) I get from the read­ers of my blog and the an­swer is: vir­tu­al­i­sa­tion. In­stead of pro­vid­ing ded­i­cated hard­ware to con­sumers, providers make use of one vir­tu­al­i­sa­tion tech­nique or the other, and divide the same phys­i­cal ma­chine into nu­mer­ous self-con­tained servers. Con­sumers can run var­i­ous ap­pli­ca­tions on th­ese servers, such as a blog, pur­chase/lease th­ese servers with shared re­sources at very low prices. This is a win-win sit­u­a­tion for the con­sumer as well as the provider, in most cases. The con­sumer gets a ded­i­cated and iso­lated server with full root user ac­cess, and the provider leases a part of the ded­i­cated server at a low cost.

You might ask how this is dif­fer­ent from nor­mal Web host­ing. Well, first of all, you do not get shell ac­cess to a shared host­ing server, let alone the root level ac­cess. Sec­ond, the per­for­mance you get with Web host­ing ac­counts ranks very low com­pared to what you get from a vir­tu­alised server.

A good place to start the search for cheap vir­tual servers is http://lowend­box.com/

This will list all the avail­able OpenVZ ker­nels from the repos­i­tory. Choose the one that you want to in­stall ac­cord­ing to your server op­er­at­ing sys­tem ar­chi­tec­ture:

This should also up­date the GRUB (boot­loader) en­try, but I rec­om­mend you cross-check that the vzk­er­nel is booted by de­fault ev­ery time the sys­tem restarts. Open /boot/grub/menu. lst with your favourite text edi­tor, and make sure the value of de­fault is set to 0 and the ti­tle OpenVZ (ker­nel-ver­sion) is on the top of the var­i­ous lists of avail­able ker­nels. Re­fer to Fig­ure 1.

If you are us­ing a dif­fer­ent boot­loader (such as sys­linux), then check the con­fig­u­ra­tion file ac­cord­ingly.

Be­fore re­boot­ing the host server, in­stall a few other good­ies that are needed in or­der to cre­ate/man­age the con­tain­ers:
