The word VPS (Virtual Private Server or virtual private server) to a virtual partition within a physical server where one or more virtual machines are running. The virtualization to which this term refers consists of dividing the aforementioned physical server into one or more logical dedicated servers or VPS that, despite sharing the same hardware, are separated from each other. Each VPS has its own operating system, which includes users, IP addresses, memory, processes, and everything that is part of a system.
To explain it in a simpler way, if we could cut a physical server into slices, each slice would be a VPS. The good thing about this type of virtual machines is that if the portion that has touched us is 10% of the resources of the physical server, we will have that 10% of resources assured and, on occasions when we need more for more demanding specific moments, we can also leverage the resources of others VPS, as long as they are not being used at the time we need your support.
VPS, everything is advantages
In addition to the above advantage, there is also another reason why VPS is interesting: we will only pay for what we need to use. For example, if we have a physical server with X-GB of RAM and we need to expand our equipment with a processor or a hard disk, the normal thing would be to turn off the machine, install the new component and turn it on again. If need expand our VPS-based team, we can do it without having to stop it, which will save us time, work and be productive. Thanks to this, we will be able to hire only what we need at all times, which also ensures that we will have greater control over what we spend.
Differences between dedicated, shared and VPS servers
Dedicated server
A dedicated server is a machine arranged for the web service that offered to a customer under an exclusive rental contract. Each client takes advantage of the performance of the server they have contracted without depending on resources from other servers or external clients. Generally, a dedicated server is hosted in the data center of the company that offers us the service. This plan is the best option for clients who have a professional website who need to take advantage of the maximum performance of a machine to which they have full access due to how their project has been planned on the internet.
Shared servers
Shared servers are also machines arranged for web service but, as we can guess from their name, they differ from dedicated servers in that shared are used by multiple clients. Clients that work on the same shared server also share the use and performance of the server, so it is also cheaper. Regarding the latter, shared and dedicated servers could be compared to renting an apartment: if we have money to pay for it, it is best to face the expense and live alone. If we do not have enough money, it is best to find one or more roommates. A shared plan can be a good idea when we start a web project.
VPS server
A VPS server is a partition within a server that is totally independent from other partitions of the system. It can have more or less resources depending on the total characteristics of the machine and what we want to pay. A client with a VPS server can enjoy exclusive features, performance and power without having to share it, but if other clients on the same machine are not using their partition, we can also take advantage of part of their resources.
The hard part: finding a good supplier
Having clear the beautiful theory, comes the most difficult: find a good supplier. We will have this same problem in practically any service that they offer us, such as telephony. To put a slightly exaggerated case, let's imagine we contract an internet service with a company called Interfacinet. Like all companies, Interfacinet wants to achieve great benefits, which is why it takes customers, more and more, until it reaches a point where it cannot fulfill its promise. It turns out that Interfacinet reached an agreement to supply millions and millions of users, but its platform does not support as much traffic. What is the only thing that can happen? Well what the speed and quality of our connection will be very unstable and we may experience outages and outages. With this scenario, Intrafacinet would not be a good option if we want to enjoy a good internet service. Another simpler example is "overbooking" on flights. If a plane has 100 seats, 110 are sold and we all attend, there will be 10 passengers who will not be able to get on that plane.
To avoid problems when hiring a VPS, the first thing you have to check is that its infrastructure will ensure that we can always enjoy the best service, both in a more discreet VPS as in any other larger one. It should also offer the possibility of expanding it at any time in case your needs increase. It is as if a telephone operator offered 100% worldwide coverage: no matter where we went and what we did, we would always have coverage and our calls would offer great sound quality, while there are other operators that promise us the moon, but then not. we can call from our house.
Another point to value about VPS plans is to make sure they are managed. What does this mean? Well what it is the hosting that manages everything. If we are users who do not have enough knowledge to do it, managing a VPS may not be a very good idea. And even if we were capable, let's be frank: is there anything better than letting someone else do the dirty work for us?
It is clear that all these advantages must be considered in any project that we want to undertake: test before use. In any electronic device we have a guarantee that assures us that we will recover 100% of our payment if we are not satisfied and we will return it in the first 15 days after its purchase. The normal thing in services like VPS is to make the payment without knowing what the service is like, which can cause us to get an unpleasant surprise when it is too late.
What you do have to do is make sure you do not pay for something that does not meet your expectations, so be careful and look at the fine print of hosting companies before hiring services that cannot meet your expectations.
