Parallels Virtuozzo Containers

Parallels Virtuozzo Containers is a powerful operating system virtualization solution that fully exploits the capacity of information technology infrastructure by increasing the utilization of redundant resources of existing servers 2 to 3 times. with other technologies. The tool is perfectly suited for cloud server virtualization, allowing redundancy and quick change of server and cloud server plans while providing maximum density, cost efficiency, and application performance.

The reason that virtualization at the operating system level can significantly increase the density of virtual machines on each server compared to hardware-level virtualization is due to the design architecture with the following basic differences :

• Hardware virtualization : making a copy of all system resources such as operating system, CPU, memory and configuration files on each virtual machine results in 20% of processing power being consumed. This will reduce the ratio of virtual machines to each physical server as well as the overall performance of the entire system.
• Virtualization at the operating system level : Parallels Virtuozzo Containers provides a virtualization layer responsible for allocating system resources to all virtual machines - called containers. This virtualization layer only consumes about 2% of processing power, thereby increasing the rate of virtual machines on each physical server, server performance is almost unchanged compared to when running independently.

The main feature of Parallels Virtuozzo Containers:

Designed to provide profitable cloud computing services

• Advanced resource management provides the necessary control to support multiple VPS and Cloud server packages with multiple levels of CPU, memory, I / O drive space and storage space.
• The " elasticity " of a virtualization environment allows customers to easily and flexibly upgrade service providers.
• Fast backup and activation provides the fastest availability time for new VPS and Cloud server registrations, allowing customers to add new services immediately.
• Comprehensive integration for 3rd party systems is enabled with the command line and API interface thus simplifying the process of automated provisioning and service billing.
• Resource isolation and performance allow service providers to ensure SLA and provide a reliable and highly secure virtual server.
• Flexible management options minimize administration and support costs by simplifying daily operations, automating daily tasks and providing customers with self-service capabilities.

Maximize profits for hardware investments

• Lets you run more registrations on every server by creating separate and secure virtual servers without the cost and limitations of hardware virtualization.
• The dynamic library sharing function significantly reduces the amount of memory required by each virtual server and changes the way you provide registrations.
• The Virtuozzo file system minimizes the amount of disk and memory space required for each registry by allowing sharing of common operating system applications and components while maintaining the ability to customize. IOPS (I / O operations per second) has been improved by access to shared files in memory only done once.
• Cross-scheduling CPU workloads minimize the linkage of virtual environments so that vCPU can provide flexible and high-performance server to customers.

Streamline daily activities

• Operating system templates simplify the process of creating and maintaining the 'golden image' used to provide VPS or Cloud servers.
• The automatic application template is too fast to deploy and configure applications for the virtual server, allowing you to easily expand existing services.
• Automating tasks and management simplifies daily administration and increases the number of physical nodes and virtual servers that each admin can manage.
• Minimize maintenance costs by installing the host operating system and applications such as backup and antivirus on that server, not on each virtual server.
• The stability is provided by global support and service to ensure the success of your business. With over 5000 service providers worldwide, Parallels Virtuozzo Container is the virtualization product of choice for mass market hosting providers.
• A complete set of management tools for both service providers and customers to bring the best virtualization solution for VPS hosting. Parallels Virtuozzo Containers tools allow management, monitoring, backup, recovery, troubleshooting, provisioning and deployment.

Parallels Virtuozzo Containers allow you to :

• Provide the latest Windows 2008 R2 Server VPS and Cloud servers with the highest possible density for each server.
• Increase revenue by providing managed application services and operating systems that simplify the task of managing the environment for clients.
• Minimize administrative burden in monitoring and managing the process of providing Windows VPS with centralized web-based management solution.
• Upgrade each of your Microsoft Server nodes into a high-performance virtual environment platform. Minimize the complexity of server configuration settings and maximize the number of virtual servers per CPU.
