There are many reasons you'd want a VPS server instead of shared hosting. You might be deploying software that's not compatible with shared hosting, you may need root access, or you might have simply outgrown the resources of a shared hosting plan. Whatever the reason, you need to know what to look for in a VPS server.
There's no point in paying more than you need for resources you won't use - or, on the other hand, getting a plan that's too low specced for your needs. Therefore, you'll save money and time when you get a plan that fits your needs. Here's what to look for in a VPS host.
Not all of the factors below will be shown clearly on the plan specs but you can easily get this info at any reputable host via online chat.
Choice of operating system
All too often, the underlying OS is easy to overlook when seeking a VPS host, particularly in the Linux ecosystem. If the software you'll be using is only compatible with a certain type of Linux (Alma Linux for example) then you'll want to be sure the operating system is offered on your VPS plan.
It's also worth checking the version(s) available. Most reputable VPS providers do offer you some degree of choice of operating system - but not all of them offer up to date versions of these. After all, if you plan to run your project for a few years, you don't want the operating system to be outdated by then.
Port speed
If you see a VPS plan that seems too good to be true, find out what port speed they're offering. It should ideally be 500Mbps or preferably even 1Gbps.
If it's 100Mbps or less, that's a little low for this day and age. If your application is not bandwidth-intensive, nor do you have a lot of traffic, then a low port speed might be OK for now, but not necessarily in the future if you get more traffic.
Your site will appear to run slowly if your plan has a low port speed and if you need a lot of bandwidth at once. Anything with audio, video, or gaming needs to have a high port speed. By contrast, you can get away with a low port speed if you have simple personal blog.
RAM
The amount of RAM will be clearly stated on the VPS plan options. If you're not doing anything memory-intensive, you can get away with the lowest price plan. There's no need to spend your hard-earned money on a higher amount of RAM. If you do need more resources later, most VPS providers make it easy for you to upgrade seamlessly to one of the higher specced plans. All of that said, most up to date versions of Linux recommend at least 1G of RAM to run smoothly, so you'll want to be sure your plan offers at least 1G.
For simple test projects of your own, I can attest from experience that you can run a modern Linux OS on a VPS with 512M RAM. It's not recommended, but if your budget is really tight and your test project does not use much memory, then it's OK to be on 512M RAM. For any other type of project you need at least 1G though.

Payment methods
It's all too easy to be dazzled by a low price but not think about payment options. Ideally you want to have multiple options for payment method. If the VPS host accepts only credit card and no other methods, that can be a bit of a red flag. It doesn't mean anything is definitely wrong with them, but a reputable VPS provider will usually offer at least two payment methods.
In particular, it's usually a positive sign if the VPS hosting provider offers PayPal as a payment method (even if you don't plan to pay with PayPal). This is because PayPal won't like to work with a vendor that has a too high return rate. They have fairly strict requirements.
Disk space
The amount of disk space in GB will be clearly stated on your plan. Most reputable VPS hosts won't have this be a limiting factor. However, if you happen to know you're doing something space-intensive (storing images, backups, video or audio, or a lot of user data) then you'll want to make sure you select a plan with enough disk space. There is no one-size-fits-all answer for how much you need - it all depends on how much space your items take up on disk.
For the average blog site, you won't need much disk space so the lowest specced plan will be fine.
Understand however that unlike in shared hosting, the disk space on a VPS hosting plan refers to total disk space, which includes the amount that your operating system takes up. It's a bit like your phone's disk space - a chunk of it is taken up with your phone's OS which means there's that much less for your own storage.
Ports available
You need to check if there's any restrictions on which ports you can use and how many ports you can have open at one time. Some VPS hosts restrict this heavily for legitimate reasons, others don't have any restrictions at all. The bottom line is that you need to at least be certain if they offer the ports you need. Most hosts will at absolute minimum have ports 22, 80 and 443 open (for SSH, http and https). But if you're planning on using an admin panel which uses an additional port, running email, or anything that uses another port, you'll need to have other ports open for these services.
Some hosts allow you to have up to a certain number of ports (e.g. 10) open at any one time but they don't care which ones. Some will allow you to do this yourself; others will have you put in a support ticket - which obviously takes extra time.
It's not necessarily a bad thing if a host has port restrictions (they're probably trying to make sure it's a "good neighborhood"). The bottom line is to check on port restrictions and make sure their policy is a good fit for your planned port usage.
Allocated bandwidth
Most reputable VPS hosts will have a fairly generous bandwidth allowance, so for most use cases you shouldn't have to worry about this. However, if you're doing anything bandwidth-intensive, such as running a gaming server, video, or streaming, then you'll need to look for a plan that has a high level of bandwidth.
Data center locations
You'll want your server location to be geographically close to your main audience to minimize latency. Within the same continent is fine.
Most VPS hosts offer a few different choices of data center locations, but be aware not all of them may be in stock when you come to order so it's worth bearing more than one VPS provider in mind.
Most Linux VPS hosting companies offer data centers in popular locations such as the US or EU, even if the company itself isn't located in those areas.
Money back guarantee period
It's best to go with a VPS host who offers a no questions asked money back guarantee in case it doesn't work out for you. Make sure you understand the time period for this - some providers allow it for the first 30 days, others for only the first 14 days, some for even less. You'll need to read the terms and conditions on their site for this information, but it's worth looking into.
This is especially important if you're paying yearly, since you're paying a much larger amount of money up front than if you were paying month to month.
Time your order only for when you're ready to start using your VPS - don't get it ahead of time when you're about to go on vacation, for example. The clock starts ticking for the money back guarantee from when you place your order, not from when you start using it.
Support center hours and language
You shouldn't need support very often since with a VPS, you're in charge of all the upkeep of your server. That said, when you first place your order you might have some questions for them. And there are always instances that will crop up from time to time that you'll need a support ticket for, although these are usually rare. So make sure you understand the support center hours. For example, if your server's admin panel became inaccessible due to an outage at their end, would you be able to get support in a timely manner?
Make sure you also know what the main language is of the support center staff. While you can always use online translation tools, understand that you might be a bit stressed if you're communicating about some problem that cropped up. So it helps if you have a language in common even if it's not your native language - it's just easier if you don't have to add an extra extra layer of translation between everything.
Conclusion
It may seem like a challenge to get all the above factors together in one VPS hosting package, and that's OK. You'll almost certainly have to compromise on something - just make sure it's not something mission-critical to your use case.
