Nucleus no longer offers Virtual Private Servers (VPS). Technology keeps evolving and we like to jump on the bandwagon when better solutions arrive on the market. That’s why, starting February 1st, we’ve chosen to offer an alternative for the VPS: the Open Cloud Servers. We shed some light on our decision and explain what the advantages are.
VP is a collective term for all sorts of technologies, with common characteristic that it’s about virtualized servers. In the hosting sector the term Virtual Private Server refers to a dedicated server that, using virtualization techniques, is divided in to multiple small virtual servers. Through this application the price per virtual machine is lower.
Because price is often the leitmotiv with such a VPS, the paravirtualization technique is often used. Using this technique an Operating System (OS) is installed on the server with additional software that runs containers on this OS. The big advantage is that many resources remain communal, which allows you to run even more virtual machines on one dedicated server. This allows you to work cheaper. The downside is that, even though we’re talking about a private server, not all resources are completely separated. This means a problem with one virtual machine (VM) can still have impact on other VM’s on the same node.
However, the technique of virtualization has evolved enormously. A more advanced application is hypervirtualization. This doesn’t have an underlying OS, but a small hypervisor that makes virtual servers, each with their own virtual hardware. The separation between the virtual machines is very strict. The advantage is clear: everything is separated from each other. A problem on one VM doesn’t influence another VM on the same node. Disadvantage (and advantage) is that every virtual machine needs to run its own operating system and therefor needs more resources.
The Nucleus VPS’s run on Virtuozzo by Parallels. When we started with that ten years ago, it was a very strong product. During our latest market research and in our test lab it turned out that today we can work with open source hypervisors for the same price as a VPS. The price advantage of a VPS fell away because of the advantages we achieve by using hypervisors.
That’s why we’ve chosen to (step by step) convert our current VPS’s to our Open Cloud. Open Cloud works on the basis of KVM, an open source hypervisor. An added advantage of this technology is that we can provide our Open Cloud Servers (OCS) with high availability.
High availability means that when one hardware system runs into problems, other machines immediately take over the work. A VPS misses that advantage because it is bound to one specific hardware node. When the physical machine has a problem, each VPS on that node becomes unavailable. With an OCS that problem doesn’t present itself. After all, it’s about a virtual server that runs in a cloud-system where multiple nodes work together.
Other advantages of a cloud are scalability and the flexibility. You can adjust the resources of your Open Cloud Server very smoothly. Where before the VPS only existed in fixed packages, you can now flexibly adjust the resources of your system. More CPU, memory or storage is now a matter of a push of the button.
Our OCS also has the advantage that we work with storage tiering. That means that different kinds of data can be stored on different kinds of media based on their properties. There’s a choice between SATA, faster SAS and superfast SSD. You can also combine between the three. So there’s flexibility and scalability in all directions and on all fronts.
At the same time we’ve expanded the backup retention, so you can return to point a full month ago. And all of this on newer and much faster hardware.
In short: an OCS offers a lot of advantages for the same price.
We will contact our existing customers one by one in order to facilitate the migration from VPS to OCS.
Our team of specialists is constantly on the lookout for opportunities to offer the best solutions to our customers. In doing so Nucleus honors its title as Hosting Solution Builder.
