Why should SMBs chose Container-based Cloud servers?

Better application performance

In head-to-head comparisons, containers outperform hypervisors in every virtual CPU configuration. Containers eliminate the resource overhead inherent in hypervisor virtualization, resulting in significant improvement in application performance and scalability for a given vCPU configuration. For more information see our Performance Comparison white paper.

Rapid provisioning

VPSs are available to the customer within a few minutes of ordering. Parallels Virtuozzo Containers are nearly “instant on” when provisioned with no operating system boot-up time.

On-Demand upgrades

VPS resources can be changed on the fly. With Parallels Virtuozzo Containers, the resources assigned to any individual container can be modified in real time and without restarting the container, allowing administrators to adjust assigned resources to meet the requirements of the workload. And Parallels Virtuozzo Containers don’t require a re-boot to grow.

Self Service Tools

Parallels Virtuozzo Containers includes a web-based control panel called Parallels Power Panel that enables Customers to self-manage, monitor, backup, restore and troubleshoot their VPS.

Virtuozzo Performance Factors

  • System calls — Parallels Virtuozzo Containers has a common kernel; no additional systems calls are created between excess layers.

  • File system — Common data is stored only once and is available to multiple environments, significantly improving the efficiency of both the disk space and system memory. The disk space for caching is also used efficiently, caching payload rather than duplicated data.

  • File system performance — The Parallels Virtuozzo Containers file system and efficient system call design create very small CPU usage overhead.

  • File system buffers/cache in memory — Parallels Virtuozzo Containers places a single instance of data and cache across the server, maximizing memory efficiency.

  • Memory management — Parallels Virtuozzo Containers handles memory allocation requests dynamically. Virtuozzo environments can use a lot of memory during load peaks, and users will fully benefit from running Virtuozzo on high-end servers. Applications in Virtuozzo environments can show very high peak performance.

Real-World Applications

Some of the world’s largest service providers - including Go Daddy, 1&1, Host Europe and Media Temple - rely on Parallels Virtuozzo Containers to power their hosting and Cloud services.

Parallels Virtuozzo Containers offer significant advantages particularly in the following environments:

Hosted Services

Hosted services such as those that support web or application workloads benefit from the performance enhancements and disk space-saving technology used in Parallels Virtuozzo Containers virtualization. Businesses that sponsor hosted services require high levels of automation to support a successful business model, which can be fulfilled through the use of templates as well as the management toolsets that arrive with Parallels Virtuozzo Containers.

VPS and Cloud Servers

Parallels Virtuozzo Containers sets the hosting industry standard for profitable, secure and flexible VPS and Cloud server offerings. Parallels Virtuozzo Containers ensures you can:

  • Quickly provide secure, fully isolated, completed, configured Linux and Windows servers as OS containers
  • Maximize hardware investments by increasing virtual server ratios, reducing costs and improving profitability
  • Automate near-instant provisioning and on-the-fly modification of VPS and Cloud server plans
  • Lower operational costs by reducing the administrative burden of day-to-day operations

Managed VPS

Managed VPS hosting plans provide a support system to help manage VPS resources, from initial setup and installation to assistance in moving data to the new environment and choice of VPS control panel. Parallels Virtuozzo Containers enables you to create templates of standardized environments that can be rapidly deployed as managed VPS service offerings. These templates can include operating systems, libraries, security patches, updates and software stacks. Templating the offerings lets you streamline the ongoing management of the environment, thus eliminating the burden from your customers, improving your existing services and increasing your differentiation from the competition

Virtual Appliances

Virtual appliances are a great tool for any organization that regularly deploys multiple servers with the same applications. Parallels Virtuozzo Containers provides the most efficient virtualization for virtual appliances.  Delve into this white paper to see how Parallels Virtuozzo Containers enables virtual appliances with a much greater level of efficiency, manageability, resource use and flexibility.

Hosted Desktop

Containers-based virtualization is well-suited for hosted desktop environments where many similar desktops are hosted on the same server. Containers also provide benefits in disk space and memory conservation in hosted desktop environments, erasing the need for massive horizontal scaling of resources to support large numbers of desktops. KDDI, one of the largest telecommunications providers in Japan, relies on Parallels Virtuozzo Containers to deliver hosted virtual desktops as a key component of its Multi Cloud brand of cloud services.
