It works quite like shared hosting, as both of them are virtual hosting. However, shared hosting does not allow to extend or modify server settings. VPS hosting is more like a dedicated physical server on a virtual platform. You can manage and set up VPS for your requirements, as it is a separate server. Also, VPS server can be operated by a control panel that can be installed with a few clicks from the client system or the terminal command line. It means that you can even choose the same control panel as it is on shared hosting.
However another option is to pool together a cluster of physical servers into a cloud arrangement whereby the data is stored across several physical disks in several physical machines. This dramatically reduces the possibility of hardware related downtime by spreading the load and the risk of hardware failure. This is a High Availability Cloud setup which Pickaweb uses.
Speaking of email and limits, you'll want the ability to create an unlimited number of accounts. Should your website grow significantly, you'll appreciate being able to scale your email accounts without spending additional money. Web hosts typically place a cap on the amount of storage per email account. In other words, you may be able to create an unlimited number of email accounts, but each one may have a 10GB storage cap. Take time to investigate a potential web host's email offerings so as not to be surprised by its messaging limitations. Again, find out what the unlimited gotchas might be.
The most common type of VPS is a web host. Many web hosting companies offer VPS hosting solutions as an alternative to shared hosting and dedicated hosting. A VPS sits in between the two options, usually in both performance and price. Like a shared host, a VPS may share the resources of a physical machine with other hosting accounts. However, a VPS is custom-configureable like a dedicated hosting solution it is isolated ("private") from other accounts.
Shared hosting packages are aimed for small projects, such as personal blogs and similar sites. Resource intensive or high-traffic projects might encounter issues while using a shared hosting service. Shared hosting is incredibly beginner friendly and fully managed, which means that our customer support team will be able to help out with most issues that might occur with your project.
Typical Use Case: Early stage startup workloads, quick prototypes, prelaunch experimentations, dev/test environments, microservices node, code repositories, dedicated application servers for light workloads. Resource intensive workloads like data aggregation, gaming front-ends, video encoding, high performance computing, batch processing. Also see our managed services for Startupreneurs.
