Introduction to VPS hosting

A Virtual Private Server (VPS) is a virtual machine that resides on a server with other virtual machines. With a VPS, you have your own operating system installation. As a result, you have much greater control over system configuration. You can install programs and applications that are unsupported or not allowed on shared hosting accounts.

A hypervisor, also called a virtual machine manager, is the program that allows multiple operating systems to share a single hardware host. Our VPS plans use OpenVZ virtualization technology.

For people with simple websites and basic hosting needs, a shared hosting account is all they'll ever need. But if you are a developer, you may find that a VPS plan better suits your needs. Especially when the entry cost has never been lower -- you can get a basic VPS for less than $10 USD per month.

A2 Hosting offers two types of VPS account plans: semi-managed and managed. We have designed these plans to provide you with greater flexibility and control.

Managed VPS

Managed VPS plans offer a managed environment similar to our shared hosting accounts, but with increased resource availability. If you are outgrowing a shared hosting environment, but are not ready yet to make the leap to a dedicated server, you should consider a managed VPS. This plan is also a good option if you need certain customizations that are not provided with shared hosting plans, but you would still like A2 Hosting to handle configuration changes, software upgrades, and other system administration tasks.

By default, all managed VPS plans include cPanel. You can also add WebHost Manager for an additional monthly fee.

Semi-managed VPS

Unlike managed VPS plans, semi-managed VPS plans are not actively managed by A2 Hosting. Semi-managed VPS plans are for more advanced users who are comfortable using the command-line interface and doing system administration tasks. These plans include root account access so you can customize the server as much as necessary. As a result, you are responsible for the following items:

  • Application installation and configuration.
  • Upgrades.
  • Security patches.
  • Reboots.
  • Backups.
  • Custom partitioning.
  • Fixing broken user accounts and resetting passwords.

These plans are called “semi-managed” because A2 Hosting provides the following services:

  • Infrastucture management, including network, power, security, hardware, and virtual machine hosts.
  • Initial provisioning of VPS accounts (using our default templates).
  • Re-provisioning the VPS with a different operating system.
  • Complete reset of the VPS back to original settings (this erases all data).
  • Provisioning additional IP addresses.
  • Reverse DNS management and delegation.

Semi-managed VPS plans do not include cPanel. Instead, SolusVM and SSH are the primary administration interfaces. SSH also provides you access to the A2 QuickInstaller. The A2 QuickInstaller enables you to install Django, Grails, and Zope, and many more applications quickly and easily. You can even suggest additional applications to add to the A2 QuickInstaller.
