Of course, one of the most important factors in selecting a VPS is the cost attached to it. VPS providers will charge more for managed hosting and for using high end resources. Hence, you need to select a VPS which will not only operate effectively, but will also not cause a sizeable hole in your wallet.
A great advantage of VPS, compared to both shared and dedicated solutions is snapshot technology support. A snapshot is a state of a system at a certain point in time. It works like game saves in your favorite computer game. If a game is not going well, you can exit and start from a checkpoint. A snapshot works the same way; if you need to go back in time, your system can be restored from a snapshot to its previous state. It is extremely useful in case of a system failure or simply if you run complex tests and wish to save your progress. Unlike a backup option that copies the whole system each time you run it, a snapshot contains only changes. This means that a snapshot takes less space than a backup and can be created/restored quicker. It does not mean that you do not need backups though. Backups are still life-savers in case of operating system failure. Don’t forget to store them externally.
Your organisation may also be interested in helping Debian using your resources. If so, you can donate to us, form ongoing partnerships with us, sponsor our conferences, provide gratis products or services to Debian contributors, provide gratis hosting for Debian service experiments, run mirrors of our software, installation media or conference videos or promote our software and community by provide a testimonial or selling Debian merchandise, installation media, pre-installed systems, consulting or hosting.
Shared hosting is not meant for websites that use large amounts of RAM. As your website grows and you add more and more content, you will start to see a decrease in your website’s load times. As soon as this happens, it’s an indication that you are maxing out your limits. Upgrading to a VPS will enable you to scale your website without having to worry about slow load times.
A VPS doesn’t just have more RAM, disk space, and a proprietary share of CPU than a shared account. Depending on the provider, some VPS plans offer burstable memory, which is a pool of RAM set aside for extraordinary events. This is the stuff that can help counter the so-called “Digg-effect,” that much-whispered about occurrence that’s the simultaneous hope and fear of everyone who runs a web site. When you have an unexpected high traffic event, burstable memory will call on a pool of reserved, shared memory to satisfy the needs of temporary high traffic. This is not available on shared servers and, while the necessary memory is available on a dedicated server, your site might not get the kind of traffic on a daily basis to justify the expense of a dedicated server. Again, not all VPS plans have burstable memory, so ask your provider if their VPS plans do.
