The proftpd and BIND9 services are probably not necessary (SFTP and external nameservers are better) and can be disabled by going to Webmin > Bootup and Shutdown and clicking Stop Now then Delete. You can also disable the ftp port in Webmin > Networking > Firewalld. Do NOT disable DNS port 53 on either TCP or UDP because responses to outgoing queries could be blocked.
And if your “neighbor” on the server is hacked, there’s little chance the infection will spread to your VPS because the hypervisors that are used to create separate VPS environments deliver multi-layered network security and keep tight controls on what enters and leaves. Your root access also means you can add or customize your VPS security software as you please.
There are a few downsides to shared hosting, though, mostly because you’re sharing. For instance, if someone else on your shared server has a huge spike in traffic, that could affect your website’s performance. However, if you’re just getting your website off the ground and don’t have huge traffic volume, shared hosting is a great way to get online!
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.
Once you register your website's domain name, it's time to start picking the specs for your server. Web hosts typically offer multiple VPS plans that have varying amounts of email capability, RAM, storage, CPU power, domain hosting, and monthly data transfers. The plans typically include website builders that let you quickly create a face for your site without much—or even any—coding required. A solid web host should offer at least 4GB of RAM, 100GB of storage, and an ample volume of monthly data transfers. If you expect a significant amount of website growth, then you should look for a web host that has as many unlimited offerings as possible. For example, Hostwinds—the PCMag Editors' Choice for VPS hosting—offers unlimited email, domains, and monthly data transfers. Note, however, that as with all unlimited service offerings, you really need to read the fine print to make sure that what you mean by unlimited and what the hosting service means by it.
