Virtuozzo Review

Allocate System Resources To Multiple Isolated Containers Using A Common Virtualization Layer

Virtuozzo boasts its efficient, secure, light-weight, and high-density containers that permit users to implement a virtualization approach wherein they will be able to establish a common virtualization layer that distributes a single set of system resources throughout multiple isolated containers or virtual instances. In this approach, a single operating system kernel gains the capability of supporting multiple isolated containers instead of just a single container.  Also, Virtuozzo containers behave like real physical servers, providing users with virtual servers that match the performance of physical servers.

Performance And Density That Exceeds Traditional Virtual Machines

Virtuozzo containers exceed the capabilities of traditional virtual machines in terms of performance and density. That is why these containers are described as efficient and lightweight. The containers can run more servers and process client requests faster compared to traditional virtual machines.

Advanced Memory Management

Virtuozzo offers an advanced memory management feature powered by an auto-ballooning technology. With this feature, memory usage patterns are predicted based on accurate and reliable statistics gathered from guest operating systems. This enables users to reclaim unused memory from guests and reduce their overall memory footprint. They can run both containers and virtual machines together without the need to use high memory overhead.

Optimized KVM-Based Hypervisor

One of the powerful virtualization technologies offered by Virtuozzo is its hypervisor. Generally, a hypervisor is a software solution that separates applications and operating systems from physical machines and runs them on virtual machines. The Virtuozzo hypervisor was built through the recreation and enhancement of the popular open-source hypervisor called KVM or Kernel-Based Virtual Machine. This is a powerful and industry-leading hypervisor that has been empowering organizations to build virtual environments and quickly deliver desktops and applications to end-users which they can be accessed remotely.

Compatible With Upstream Projects

Because the KVM is an open-source hypervisor, the changes and enhancements implemented by Virtuozzo’s vendor on its hypervisor are being supported by the upstream community or those people who originally created and developed the KVM. In other words, the Virtuozzo hypervisor is fully compatible with upstream projects and gives users the assurance that any modifications applied to it in its subsequent versions will be back up by the upstream community.

Ready-To-Use Hypervisor That Offers Native Support For Windows Guests

The Virtuozzo hypervisor is a ready-to-use virtualization solution which means users can run virtual machines using the hypervisor without worrying about compatibility issues. If they want to apply their own specific configurations, the hypervisor will be able to support them. In addition, the hypervisor offers native support for  Windows family which means it allows users to run Windows guests or virtual machines just like how they usually run them on Hyper-V without applying additional configurations. Hyper-V is a hypervisor developed by Microsoft.

Scalable Software-Defined Storage Solution

Virtuozzo comes with a highly-flexible and distributed software-defined storage solution built in order for organizations to easily implement a hyperconverged infrastructure while being able to reduce storage costs. This software-defined storage solution can be scaled to meet the specific needs of any organization. In fact, it can support any workload or data type as well as the most popular containers being currently used.

Works With Off-The-Shelf Hardware To Drive Costs Down

Virtuozzo’s software-defined storage solution is indeed extremely cost-efficient. This is because it is compatible with off-the-shelf hardware or those ready-made hardware products that organizations are purchasing and configuring to meet their unique needs. They prefer to purchase these hardware products over those ones that are custom-made which are obviously expensive.

Stores Petabytes Of Data

As mentioned earlier, the software-defined storage is scalable. With this solution, a single storage cluster alone can accommodate multiple petabytes of data. Users can also easily manage storage because the solution has a web-based management user interface where they can centrally perform storage tasks and monitor storage activities.

Erasure Coding And Storage Management

The software-defined storage solution offers features that enhance security. One of them is erasure coding. This is a data security method through which a data is broken down into fragments. These fragments then are encoded with information related to the data and stored across different locations. So what’s the significance of this feature? It allows users to easily reconstruct their data whenever an incident of data loss or corruption happens. All they have to do is to get the fragment of the data and use the information encoded into it, and then they can already reconstruct the lost data.

Storage Tiering And Data Encryption

The solution, furthermore, has a data encryption feature. This feature enables users to organize storage spaces into storage tiers. On this storage tiers, they will be able to store and encrypt data that are organized into different categories. They have the option to apply encryption only to specific storage tiers or all of the tiers.
