Most of us have heard about shared hosting, for personal use, and virtual dedicated server hosting, which power the infrastructures of large companies. However, if your company is somewhere between personal use and these corporate giants, there is a third alternative, VPS. 

What is VPS?

VPSs (virtual private servers) are isolated virtual environments created from a physical server by a process called "virtualization". This means that you can actually have your own custom server solution at a fraction of the cost of a full dedicated server. A bare-metal server brought several VPSs homes at the same time. The other great advantage of VPS hosting is scalability: depending on your needs at any given time, you can easily add or remove resources and only pay for what you actually use.

Flexibility is the end game

Although hardware resources are shared, each client on a VPS always gets its own software environment (operating system) and therefore more flexibility to play and for all users, a VPS is almost equivalent to a fully equipped computer. Virtual Private Servers can be managed or unmanaged, with the customer taking full responsibility for software updates and patches. Being isolated means that VPSs are perfect for running SaaS projects (such as a personal cloud or VPN server) or websites that have a reasonable number of concurrent users.

VPS vs Shared Hosting

The very reason why VPS first appeared on the market was to fill a gap between dedicated servers and shared web hosting offers. For small and medium businesses as well as IT managers, it represents the "Golden Loop" of web hosting; not too complex, not too expensive, not too slow, just the right balance.

Shared web hosting can be very cheap and great for novices, but in the end, you get what you paid for, which is the lack of flexibility, especially when it comes to handling traffic spikes (for example, Christmas sales or a popular page) or when a website has simply exceeded its initial hosting capacity.

The ability to evolve quickly without complexity or additional costs and with at least an order of magnitude distinguishes VPS from other types of hosting.

VPS vs dedicated server

VPS costs a fraction of a dedicated server and is much more flexible because you don't have to pay for extra capacity or resources that will be unused. Instead, most providers allow customers to transition seamlessly between different levels based on demand.

Traditional VPS vs Cloud VPS vs SSD VPS

Traditional VPSs tend to use hard drives for storage; however, some vendors, such as, have completely abandoned hard drives, not only for performance but also for reliability reasons, and have equipped their servers only with SSDs (solid-state drives), hence the nickname SSD VPS. SSDs are ideal for serving simultaneous users because they can handle a large number of input/output operations simultaneously.

Cloud VPS hosting extend the virtualization paradigm to multiple servers rather than just one, making it more redundant but also more expensive.

In traditional VPSs and SSDs, a hardware failure will affect all VPSs hosted on that particular machine. Cloud VPSs add a layer of reliability, allowing websites and services to run without significant disruption, even if a server is physically removed from the server cluster.

Enterprises that opt for a cloud VPS are likely to seek stringent service level agreements (SLA) because downtime would be very costly. Some providers, for example, offer an SLA of 1,000%, which is 10 times the rental amount prorated for the downtime of the services involved.
