The web hosting company will also provide regular web server software, installed programming language extensions, & firewall upgrades. Managed VPS plans running Windows normally include the use of Plesk for administration of domains and web server settings, while VPS plans running Ubuntu, Debian, Slackware, etc. can be administered using Webmin or Virtualmin under a free open source license.
Think of a shared server as a large apartment complex, and all of the individual apartments are rented by other website owners. All of you need a place to live — just like your website’s files — but going out to buy a huge family home would be too expensive for your needs. Sharing common areas and utilities in an apartment block helps keep costs down. And the same is true for shared hosting.
The Virtualmin interface is another way a hacker could get root access to your server. I strongly advise enabling two-factor authentication for all top-level Webmin users or any user with "sudo" access. You can do this at Webmin > Webmin Configuration > Two-Factor Authentication. I find it easiest to select "Google Authenticator" as the provider but to actually use Authy to do the authentication (because it saves messing around with API keys and because you can recover your account if you lose your phone).
You’re paying more, so there SHOULD be a minimum uptime guarantee and better server speed. Look for a host that offers 99.5% at a very minimum, although ideally, I’d rather go with someone who offers 99.9%. Search through some reviews as there are many who have put this to the test. For example, any of WHSR’s many web host reviews include an uptime record as one of our key tests.
Keep firmly in your mind the sort of assets that you require to serve your site(s) when seeking a host. Cost in a VPS is important, but not as key as you might think. VPS resource availability is scalable, so the cost that needs to be looked at is comparable cost from one host to the next. Also – as cPanel revised their pricing model recently, web hosting companies across the board will have to pass those costs on to users sooner or later. You will need to consider the cost of control panel when selecting a VPS plan. Companies like ScalaHosting has developed their own control panel to mitigate this issue – so their users would have little issues with the price hike.
Unlike most shared web hosting plans with unlimited domains, almost all VPS hosting plans include metered bandwidth limits of between 1-5 TB per month. VPS hosting plans have better resource utility panels for administration than available with cPanel where web traffic statistics can be accessed in realtime and the levels of RAM, CPU cores, or bandwidth limits can be adjusted.
Time4VPS is very affordable. It has a variety of reasonably priced plans, starting from just 2.99 EUR/month.
Note that I have included tests from some reputable DNS blacklists - these can make a big difference to server load. Barracuda requires you to register your IP address. Note also that I have enabled memcached to avoid a problem with "unable to get exclusive lock" errors in the mail log. Memcache is also useful for caching plugins like W3 Total Cache in WordPress. You can install it with a simple APT command:
Be careful, though – there are some common traps many people fall into. Firstly, the promotional prices are only on offer for a month, after which you’re paying between $49.99 and $299.99/month on any of its five plans. Secondly, the 30 day, money-back guarantee is only valid for those who subscribe for a year or longer. Everyone else only has 48 hours to claim a refund.
