Virtuozzo vs VMware

By | July 23, 2011

The word “virtualization” is similarly related with two biggest name Virtuzzo and Vmware, although so many differences about features and functionality are present in these two solutions. Now we discuss about their differences.

Flexibility :
The level of virtual server creation is a main difference between Virtuozzo and VMware. In case of VMware, it create different virtual servers directly with hardware on the another side  Virtuozzo create different virtual server at the operating system (OS) level. With virtuozzo solution every virtual server run on common physical hardware which have to use single common operating system. That’s why there is a limitation on overall  functionality. On the another side VMware does not face these kind of issues, because it creates virtual server at hardware level. So, administrators can use their favorite operating systems. The great thing is that, VMware permits users to use different flavors of Windows and also Linux to operate in harmony on a common host.
As we previously discussed that, VMware creates virtual server with hardware level so, it can offer virtual memory to users. Virtual memory is a very useful thing, it permits users to utilize free disk space as temporary storage for whichever applications run out of physical memory or RAM. It also develops the stability and performance level of the system tremendously. On the other side Virtuozzo can provide single operating system to all virtual server and virtual memory is not present. If users have additional disk storage on their server then the whole disk work as a  virtual memory.

Security and Reliability :
If all Virtual machine of a single physical server choose one common operating system to run then it would be a cause of weak security system and code faults. In this environment if any case any one operating system is hacked and the OS experiences a failure because of a bug in a software, then they all do. Also every new patch which you install on a  Virtuozzo environment requires to be approved by the software provider. In case of VMware, it can utilize  critical operating system patches.

At the end of this discussion we can conclude that VMware permits users virtual servers with a excellent uptime, simple portability and robustness on the other hand Virtuozzo is a OS level virtualization and it has it’s own limits.
