For server software we require reliability, flexibility, speed, efficiency, safety, and openness.
With simple friendly licence terms, and no artificial limits (or licencing) on things such as the number of users or the number of CPUs.
This is an Enterprise Linux. It's lean, efficient, well-hardened, and supported for a long time.
We think it's the ideal foundation for industrial and commercial systems, and are confident that you'll agree once you have some understanding of it.
Wherever possible we run it as a Virtual Machine. A major reason being that fast recovery is possible if the server hardware fails.
It's free to download and use. We charge for our expertise and time in producing a system that does what you need it to, and for any hardware.
Providing any or all of the standard services, plus whatever services are provided by applications.
All being run more efficiently and safely than you'll have experienced with proprietary servers.
When an SQL database is needed we use PostgreSQL. We've been using it since 2004 and have yet to find a reason to use a proprietary SQL server instead.
We can support Linux-based servers that we supply and other Linux installs that we perform. Remotely via a secure internet connection whenever possible. We've been doing it routinely for moe than 20 years.
For non-warranty support the basis can be either pay-per-instance or a contract for up to a specified number of hours. The per-instance response time is slower because we need to obtain a separate authorisation-to-act for each one.
It had easily delivered what was required, and successfully blocked all of the literally billions of attempts to breach it.
