Recommended Host for Virtuozzo
What is Virtuozzo?
Virtuozzo is a Virtual Private Server (VPS) application from Parallels. This platform is used to create virtual web servers and other virtual machines. In traditional virtualization, applications build out fully virtualized systems that have their own operating systems, but Virtuozzo takes a different approach by creating ‘containers’ – which are all controlled by one centralized operating system.
The advantages of containerized computing like this are many and one of the main benefits is the amount of density in applications that can be achieved on a single physical server, going far beyond the levels achieved by normal virtualization. This VPS is essentially a stand-alone server with a unique IP address, and distinct access to memory, files, applications and processes – it is even accessible remotely just like you can access your average everyday server. In addition to that you can install software, create resilient systems through clustering and just about every type of system infrastructure you may need.
The difference is that through Virtuozzo, you can exceed the limitations of what a physical server can do. For example, these containers are easily backed up to separate nodes of hardware. They can be migrated off to separate hardware as well. That means you have an added reach of extensibility which can be leveraged for more robust systems and capabilities. In addition, Virtuozzo allows for real-time tuning and configuration changes to container resources, meaning you can tweak factors of utilization like CPU usage, memory usage, network usage, I/O and disk utilization. By allocating resources throughout and among the various containers you have set up, you have the power of a rapidly tunable platform of application delivery at your control. Because it is centrally managed, you can count on updates and system patches being an easy application. Deploying VPS and container systems can happen in just a few seconds.
VPS is also looked to as an economical solution that not only saves time, it saves money as you can host a number of containers on just one piece of physical hardware. Today’s data centers are filled with servers and other equipment that is underutilized, so maximizing this is a bit of a ‘green’ ecological solution. If you are looking to find a hosted VPS, the advantages are that you can run either one high performance website within that VPS and you can stave off the need to acquire, configure, operate and maintain an entire physical server. It is also a high performance system which means that there are cases where you can also avoid launching multiple websites to get the job done.
What is it like to run in a hosting managed VPS?
Some hosting providers offer managed VPS for the ultimate in ‘set it and forget it’ value. You can purchase your VPS, install all of the software, modules and other configurations you need for your site for example. The hosting provider uses the power of centralization in a VPS like Virtuozzo to streamline operations like patching, kernel maintenance and so on so that you can have the trouble free resources you need with a minimum of headaches. Another advantage of course is the price savings which is shared with the customer. At a minimum, the customer can be sure that the platform they’re running on is well-maintained and the operating system is up to date.
Unleash the Power of Virtuozzo
Once you have a VPS, it’s interesting to see what you can do with it. Production environments are suitable for a flexible environment like this. Running a high performance website is high on the list, but you can also run a dedicated mail server. You can run a backup email server to strengthen your own disaster recovery scenarios within a VPS instance. Depending on the provider, you could possibly run a virtual ISP, buttressed with all the dedicated resources you may require. ISPs on VPS usually involves launching a CPanel or Plesk type of control panel.
Perhaps one of the most compelling reasons to use a VPS is for the programmer and developer audience. This is attractive to these users for the reason that it saves them the costs of hardware purchasing and configuration time. A developer can stage a dedicated environment for application development with ease and quickness. Additionally, any time saved in development is money saved or not spent. The list goes on and on, covering any application or system that has high performance needs like database, processing, number crunching and more.
Virtuozzo is a popular choice on the market because of its efficient design, performance and complete suite of management elements and it is part of the reason why it is a popular choice as a client and platform for customers around the world today.
Virtuozzo Frequently Asked Questions
What is Odin?
Parallels has split their operations into two paths. The cross-platform group that creates Parallels Desktop will continue to use the Parallels name while the service provider team, which makes Virtuozzo, is now called Odin. The move is intended to allow each group to focus on their specific area.
What is a virtual web server?
A virtual web server is a virtualized hosting platform in which a single computer is utilized to host any number of virtual servers. This allows web hosts to significantly reduce costs and maintenance, as they do not need to maintain a single computer for every client. It also provides many advantages to clients, as they receive the benefits of a dedicated server for significantly less cost, and they can easily increase the size of their server and resources available, without requiring any change to the underlying hardware.
Are there any disadvantages to VPS?
The most significant disadvantage to using a virtual private server is that, even though your virtual servers is separate from all other virtual servers, you are still sharing space on the same physical machine. If the host attempts to cram too many virtual servers onto the same computer, or if one of those virtual servers starts using too many resources, it could impact performance for everyone else. This is where programs like Virtuozzo come in. By changing the way a virtual server handles its data and the use of containers, it can dramatically increase the performance of a virtual server.
How is Virtuozzo better than a traditional VPS?
Virtuozzo offers many advantages over traditional VPS. It can provide three times more virtual servers than traditional hypervisor solutions, allowing hosting providers to dramatically increase their offerings without expanding their existing infrastructure. Using Virtuozzo’s centralized management system, providers can streamline maintenance and reduce those costs by up to 75%. By distributing data across all of the available hard drives, Virtuozzo dramatically increases speed and performance, and can be comparable, and sometimes better than, locally attached storage.
Does Virtuozzo work for Windows server?
Yes, the virtual machine manager, or hypervisor, used in Virtuozzo is capable of running Windows servers.
How does Virtuozzo help protect my data?
Virtuozzo allows you to maintain multiple copies of each storage system and recommends maintaining two or three copies, which means even if one or two hard drives fail, you will not experience any data loss. Additionally, Virtuozzo provides the same built-in data redundancy as a mirror RAID1 array.
Can I add or remove data copies?
Yes. You can change the number of data copies you are utilizing at any time. Virtuozzo will adjust in the background, either by creating new copies or removing copies you no longer need.
How much storage can Virtuozzo support?
Virtuozzo can support up to 1 petabyte of available disk space, which means if you are mirroring with 3 copies, up to 3 PB of physical disk space.
Do I need to use any special hardware to run Virtuozzo storage?
Virtuozzo was built to run on most any server systems, including commodity nodes with traditional SATA drives and 1GBit Ethernet networks. However, certain types of hard drives and RAID controllers may cause issues with some of Virtuozzo’s features. Before installing Virtuozzo, you should consult their online documentation and check your hard drive manuals to ensure compatibility.
Do I need multiple nodes to run Virtuozzo?
No, but running Virtuozzo with a single node would be a lot like driving a Lamborghini through rush hour traffic. You won’t experience the true speed and performance advantages the technology offers. However, if you are planning to expand in the near future, go ahead. Virtuozzo makes it easy to add additional nodes and hard drives. And once you do, you can roll those windows down and feel the wind in your hair.
Will I see any benefit if I add additional storage disks to my cluster?
Absolutely! Virtuozzo distributes data across all of the hard drives in a cluster, which means even a single client will likely see the benefit of additional storage nodes as their applications are able to take advantage of the increased IOPS (input/output operations per second). In some cases, this can allow clients to experience speeds far greater than they would from locally attached storage.
Is there any way to test out Virtuozzo before I commit?
Yes. You can download a trial version from their website. With it, you will receive full functionality for 30 days.
Can I use Virtuozzo to create a Mac server?
At this time, Virtuozzo can only be used to create Windows, Linux, and FreeBSD servers.
Do I need any specific software on my server to install Virtuozzo?
No. Virtuozzo installs directly onto your server, so it does not require any specific software or operating system to run it.
What are the system requirements?
Virtuozzo requires an x86-64 platform with Intel VT-x or AMD-V hardware virtualization support, at least 1.5 Ghz processor, 2 GB of RAM (4 GB or more is recommended), at least 40 GB hard drive space (see documentation for specific partitioning requirements), and at least 1 ethernet card (1 Gbit or faster).
