The two environments have plenty of overlapping qualities, but most importantly Dedicated Server render greater security, customization and excellent availability. With granular control, you are free to customize hardware components like disk space or RAM and installation of unique operating systems. More substantial computing power (CPUs) and disk space allow Dedicated servers enhanced performance for high amounts of traffic. When uptime and performance are critical to your business Dedicated Servers are second to none for hosting.
Vrtualbox is an alternative to using VMware or when the old days you would use Virtual PC. It allows 64-bit operating systems and Irving and especially for testing 2013 and are more advanced nav features. It’s a great product because it also performs very well. So I’ve already downloaded the VirtualBox here so I would just go through the install. And it’s one of those simple ones is just like those next-next-next. It will give you a warning here that it actually will shut down the network interface for a short second. It’s not different than what virtual preceded.
So that could be either a virtual machine - an operating system running inside another operating system, or a virtual private server - you rent a virtual server from a company, so you have your own internet-facing server running 24/7 relatively cheap (since it's not a real server, but one of many virtual server running on an actual server). I think he might have meant the later, since you'd have to run a snartnofe (btw I love that name) non stop to benefit from it.
Virtual servers are scalable and come with dedicated core and memory allocations. They are a great option if you are looking for compute resources, that can be added in minutes, with access to features like image templates. The hypervisor is fully managed by IBM Cloud, and you can perform configuration and management tasks by using both the IBM Cloud customer portal and the API. Virtual servers are deployed to the same VLANs as physical servers, allowing you to spread workloads across virtual servers and bare metal servers while maintaining interoperability. Virtual servers are fully customizable when you 
order them, with options to scale up as your compute needs grow.
A VPS runs its own copy of an operating system (OS), and customers may have superuser-level access to that operating system instance, so they can install almost any software that runs on that OS. For many purposes they are functionally equivalent to a dedicated physical server, and being software-defined, are able to be much more easily created and configured. They are priced much lower than an equivalent physical server. However, as they share the underlying physical hardware with other VPSes, performance may be lower, depending on the workload of any other executing virtual machines.[1]
