Shared hosting is like you are living in a room with a lot of friends. It means you must fit in the same room and you must split the cost of several things because it is affordable and cheap. However, several individuals are sharing the same space, it means everyone needs to live within a space with restricted resources among them. You will have to use the same things (that sounds a little unhygienic).

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.
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.
Cloud VPS is a type of hosting where multiple companies use isolated instances on the same host or parent server. This is perhaps the most common type of VPS hosting — when you hear someone talk about VPS, it’s most likely Cloud VPS. As you probably guessed based on the word “cloud,” another benefit is that you can access your Cloud VPS environments from anywhere.
Having your own guaranteed CPU and RAM gives you a great deal of autonomy. You don’t have to share them with any other accounts, so no matter what anyone else does they will never slow you down. Regular shared hosting is okay if your website traffic doesn’t change much, but if there’s a chance it might need more horsepower then VPS is far more flexible. And from a security point of view, the fact that VPS hosting accounts are cleverly separated on the same server makes them much more robust than a shared hosting solution.
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.
However, if a bad user shares your server with you, they can threaten your security and allow hackers to easily reach your content and critical data. Furthermore, because you’re all sharing the same resources, if any of the users that you’re sharing your server with use a lot of memory or their site has a lot of traffic, your website’s performance is likely to suffer.
