A virtual private server (VPS) is a virtual machine sold as a service by an Internet hosting service. A VPS runs its own copy of an operating system, and customers have superuser-level access to that operating system instance, so they can install almost any software that runs on that OS.

 

Nice description in this post: https://www.wiredtree.com/blog/what-are-the-best-hosting-options-for-small-and-medium-businesses/

"Virtual Private Servers use virtualization technology to partition a powerful server into smaller “virtual” servers.

From the outside, a VPS looks just like an ordinary dedicated server. Virtual private servers are completely configurable. You can change any of the software within the VPS to meet the needs of your business. Virtual private servers can also be very quickly upgraded to add extra resources, which means that you can start with a low-resource VPS and scale up as required by your business.

There are two broad options for virtual private servers: managed and unmanaged. Managed virtual private servers are configured, monitored, and supported by the system administrators at the hosting company. With unmanaged virtual private servers, customers are more or less left to their own devices, which means, unless they are experienced with the Linux operating system and managing servers, they will probably have to hire a system administrator of their own.

Virtual private servers are the best hosting option for small businesses that would like complete control over their hosting environment."

 

You can basically log in to this server remotely and play/tinker at will.

 

Giving an example of our daily life, a VPS can be compared to a large slice of cake. It is a part of the cake and comprises the same ingredients and flavour. The slice can be enjoyed by an individual and that too at a much lesser cost associated to the full cake (i.e. dedicated server)

 

Virtual Private Server (VPS) Hosting is like living in a simplex or half-plex where you can customize everything to your tastes. However, you still need to maintain your area. Companies that deal with resource heavy applications and secured data most often use VPS.

You can opt for VPS hosting in any of the following cases:

• Expansion of your business beyond shared hosting level.
• An expectation for a significant increase in traffic over the next few months.
• Plans to work with confidentially secured data in your business.
• Intention to increase headcount which in turn requires a greater email capacity.
• Plan to host multiple sites, blogs or different applications very soon.

In other simple explaination. You own a house (dedicated server) and you partition it into many smaller room (vps). Each room stay by different client and client only have their own access to enter his room.

So each of the client will have own access to decorate their own room.

 

Basicly virtual machine installed on a physical computer. It has all the capabilities of one physical server but can't use all of it's hardware. You dedicate part of the resources for this machine and it works just fine If you have more powerful hardware you can add more than one virtual server

 

A VPS is actually a shared hosting that typically shares resources from a dedicated server. The main difference between a typical shared hosting (or a cPanel hosting) and a VPS is, on a VPS you can install your own OS and software. But you are also required to have server management skill, even if you are on a managed VPS.

Now that many decent shared hosting providers use CloudLinux to offer shared hosting, difference between a VPS and a shared hosting is even less, in terms of seperating clients from one another on the same single server. CloudLinux isolates each user in its own virtual environment and keeps them separate from impacts and issues of other users.

If you are concerned about security and do not have a good hand over server management, I'd suggest to go with a shared hosting or a semi dedicated (shared hosting with more RAM/CPU/IO) hosting with a decent provider. VPS cannot offer greater security if you cannot harden and maintain it, while everything on a shared server is maintained and monitored by your provider.

 

Good communication and customer service is key to a great web-host, so choose the host with highly trained support team.

 

Would a forum be a resource heavy application? In some cases, a blog would be, depending on the size. However, size could make a difference in whether or not a forum needs a VPS.

 

A virtual private server (VPS) is created when a physical server is divided into smaller, virtual container. Just like a dedicated server, a virtual private server has its own operating system, dedicated storage, dedicated RAM and CPU resource but it costs much less than a dedicated server
