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.
The moment you plan on running an online store is the moment you should upgrade your hosting plan. Why? Because with VPS, you have a secure and dedicated virtual server where you are more likely to pass a PCI compliance test. The Payment Card Industry Data Security Standard was established by major credit card brands to protect against cardholder data theft.
VPS hosting is a very scalable solution by its very nature. Virtual machines don’t depend on their physical server; as we have said, they don’t even recognize it exists. If a VPS needs to be upgraded or downgraded, all a hosting provider needs to do is to adjust the limits for this VPS in a hypervisor. After reboot a guest OS will work like nothing happened, using new hardware quotas. This comes in handy if you are not able to estimate the technical specifications you need before you run some tests. Also, if you have a seasonal business (e.g. you sell beach equipment), you can choose to have a more powerful server during your peak demand season and a cheaper one for the rest of the year.
I have used shared hosting for over 7 years before I finally decided to upgrade to a VPS server. When I was using shared hosting, I had so many problems with malware, slow loading time, brute force attacks and so many other issues. Now, my life is so much easier with VPS. What amazes me the most is the support team; they simply exceed my expectations and they are ALWAYS available to answer my questions.
