Most of our customers are hosting providers, who typically run our software bare-metal or on some hypervisor. There are however a growing number of companies in the managed service (MSP) segment that like to offer services such as email security without having to do the actual hosting. Instead, they rely on cloud computing (VPS) providers such as Google, Microsoft, Amazon or Rackspace.
A few years ago, many cloud providers offered only “PV” virtualisation, where the guest OS had to be aware of the hypervisor (and thus, customised). They required custom boot loaders, partition formats, initialisation scripts, agents and PV kernels. Because of our “full image update” method (completely overwriting the system partition from an update partition, making updates are quick and reliable), having custom images wasn’t an option. Every Halon email gateway runs the exact same software image. Consequentially, running on such services isn’t possible.
Now that most providers, even Amazon EC2, offers full “HVM” virtualisation, we decided to create public images for a few of these providers in order to make it easier to launch our software on their platforms. We currently have public images available on
Halon is a flexible security and operations platform for in-transit email. It enables companies that build and operate large-scale
email services to offer competitive features by rapid implementation, and to lower costs of maintenance through
reliable deployment and reduced complexity.
