Every plan has some appealing configuration options. In particular, along with support for the usual Linux variants – CentOS, Ubuntu, Fedora, Debian – you can choose Windows Server 2008, 2012 or 2016 for only a $5 a month premium. That's very good value, and if you're more familiar with Windows than Linux, it could save you from lots of management hassles later on.
Hostinger offers reliable VPS services, which can provide shelter for most small and medium businesses. The different server solutions are feature-packed, but if your project gets too big, it might outgrow even the most powerful solution. Other providers might offer similar options or level of support, but in terms of price, you will struggle to find anyone better than Hostinger.
Operating System virtualization refers primarily to Type-2 hypervisors like KVM or platforms like OpenVZ & Virtuozzo that share the Linux kernel (+ drivers) between partitions on the same web server hardware. This form of VPS is common in managed cloud plans where the web hosting company provides a custom web server stack software such as LAMP/LEMP pre-installed on a VM partition. Multiple customers can share a single dedicated or rackmount server with better security, file isolation, database, and programming language extension support than shared hosting provides, as well as having access to a higher level of web server resources when processing scripts like PHP, Python, or Node.js code. Some forms of OS virtualization will also permit Windows, Linux, & BSD to be installed on the same physical hardware.
You’re paying more, so there SHOULD be a minimum uptime guarantee and better server speed. Look for a host that offers 99.5% at a very minimum, although ideally, I’d rather go with someone who offers 99.9%. Search through some reviews as there are many who have put this to the test. For example, any of WHSR’s many web host reviews include an uptime record as one of our key tests.
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.
