Expert Overview:

You can also create "Sub-servers" and "Alias" servers. Alias servers are useful if for example you have both a ".com" and a "" domain - website visitors and mail users can use either domain and will see the same website or reach the same mailbox. Sub-servers are useful if one administrator is managing several different sites - if they all have the same owner then there's no need to log in and out to move between them.

VPS, on the other hand, is an isolated playground specifically for you. You will be able to install and use any professional software you need. It also provides more opportunities for caching the content. Imagine that you implement caching tools to provide your users with better experience and reduce the loading time of your website. Caching means that the part of requests to your website will be processed using RAM instead of a hard drive. Eventually, RAM will be filled with these requests. Since VPS deals offer more RAM then shared packages, you will get better performance using caching.

My no. 2 tip is to set up daily off-site backups, including database contents. Human error (accidentally deleting files) is an even bigger threat than hackers and in any case it's impossible to make a VPS 100% secure or reliable so you need to be able to recover quickly. Individual WordPress sites (even on shared hosting) can easily be backed up to a free Google Drive account using UpdraftPlus.
Memcached with CMS websites than the system resources provided on shared Linux plans will permit. Content Delivery Networks or CDNs cache copies of a website's files in data centers by geo-location and use DNS routing to select the version closest to the web browser or user request origin. CDN services can reduce VPS website response times considerably and reduce web traffic strain on the hardware. The main advantage of VPS hosting plans is that they provide the isolation and system resources required for advanced web server stack customizations that enable better website caching for high performance web & mobile applications at scale.

It’s very easy to recommend a company like Liquid Web — quality is of the highest standards, and you have plenty of room to grow. Throw that outstanding support in the bundle, together with the practically limitless customization options, and you get an irresistible VPS platform. Price is the only obvious dent to this otherwise superb hosting deal, so if you are on a tight budget, you might want to consider another option.
You also get the following benefits:
Essentially, here’s the criteria I would use to judge things – if your site is made up of primarily static, HTML-based content, then you probably don’t need a VPS package.  However, if you have a large amount of files stored, multiple sites, dynamic content, and the possibility of major traffic from time to time, then you might consider upgrading to a VPS. It’s a powerful package that allows you to do more than you could with a shared hosting plan, but requires less investment than a dedicated server.
The moment you plan on running an online store is the moment you should upgrade your hosting plan. Why? Because with VPS, you have a secure and dedicated virtual server where you are more likely to pass a PCI compliance test. The Payment Card Industry Data Security Standard was established by major credit card brands to protect against cardholder data theft.

Quick review: AltusHost is a well-known premium hosting provider based in Netherlands.

However, the automatically-generated certificate is "self-signed" which means users will get browser warning that the connection can't be trusted (because there might be a man-in-the-middle intercepting the encrypted traffic). The solution is to install a free LetsEncrypt certificate by going to Virtualmin > Server Configuration > SSL Certificate > Let's Encrypt > Request Certificate. If you've done everything correctly your web site will now load with no warnings.
The most obvious and popular reason for a VPS is to run a single website, or multiple websites. However, you can use them for pretty much anything that requires access to the internet – such as a web application like Nextcloud to run your own Dropbox alternative – or to create your own virtual private network to better secure the internet connection of your PCs and mobile devices.
