• On-the-fly virtual environment elasticity enables flexibility for customers and ease of upgrading for service providers.
• Immediate provisioning and activation provides the fastest availability time for new VPS and Cloud server subscriptions, allowing your customers to add new services instantly.
• Comprehensive integration capabilities for third party systems are enabled with command line and API interfaces thus simplifying the complete automation of delivering and billing for services.
• Performance and resource isolation enable service providers to guarantee SLAs and provide highly reliable and secure virtual servers.
• Flexible management options reduce administration and support costs by simplifying day to day operations, automating routine tasks and providing customers with self service capabilities.

Streamlining day to day operations

• Mass management and task automation simplify the day-to-day administration and greatly increase the number of physical nodes and virtual servers each administrator can manage.
• Live migration enables administrators to moves an entire virtual server between physical nodes without disrupting applications or users. Can perform live migration across different geographical locations if this is supported by the network infrastructure.
• Multi-platform support for both Windows and Linux servers with a set of common management tools.
• Complete set of management tools The widest set of tools for both Service Providers and customers, making it the best virtualization solution for mass hosting of VPSs. Parallels Cloud Server tools enable management, monitoring, backup, restore, troubleshooting, recovery, provisioning and deployment. Learn more.

Frequently Asked Questions

What is the difference between containers and hypervisors?

Two types of virtualization in use today include hardware virtualization (generally known as hypervisors) and operating system virtualization (commonly referred to as containers).

Hypervisor Virtualization
Replicates system resources on all virtual servers. Multiple copies of system resources, however, results in overhead on the server of up to 20%. Overhead reduces the ratios of virtual servers per physical server as well as overall system performance.

Operating System Virtualization
By virtualizing at the host operating system, Parallels Containers provides a common virtualization layer that allocates system resources across all virtual servers, called containers. The result is a leaner, more efficient virtualization layer with an overhead of only 2%. This translates into higher ratios of virtual servers to physical servers, near-native server performance and unique advantages for management of the virtual environment.

Can I deploy hypervisors and containers on the same physical node?
Yes. Parallels Cloud Server allows you to specify the number of hypervisors and containers that you can deploy on the hardware node. 

Can I deploy Windows VPS offerings using Parallels Hypervisor?
Yes. Parallels Cloud Server allows you to deploy Windows within the hypervisor enabling Windows VPS offerings that can leverage the high reliability enabled with Parallels Cloud Server.
