Around The World
Many websites, services and applications we use every day are driven by Open Source technologies, among the most famous we find the many Apache Web Servers with millions of installations, hundreds of thousand applications powered by MySQL, Postfix, SQlite, PostgreSQL, Gnu/Linux, FreeBSD, etc.
Open Source however, requires well trained specialists with a solid background in the field in order to provide support of these applications and narrow the gap between the source code and the real business needs of the customers. We have extensive experience providing Open Source support for many of these well known Open Source applications:
| • Apache | • NginX | • Mongrel | • Linux HA | • Sendmail |
| • Exim | • Postfix | • Sendmail | • Qmail | • Bind 8/9 |
| • Asterisk | • OpenSIPS | • FreeSwitch | • PostgreSQL | • MySQL |
Open Source Platforms
We understand that different business domains respond to different operating patterns and requirements, for this reason we do not stick to a specific Gnu/Linux distribution or Unix-like system flavor. We believe one of the basic ideas of Open Source is to avoid reinventing the wheel so we reuse existing resources whenever possible to achieve our clients goals. We have many years of experience working with the following Open Source operating systems and distributions:
| • GNU/Linux | • Debian Linux | • Ubuntu | • Redhat Linux | • Fedora | • CentOS |
| • Gentoo | • Suse Linux | • Slackware | • OpenBSD | • FreeBSD | • NetBSD |
We also perform integrations between Open Source and proprietary software platforms. We understand that implementations most of the time involve technologies licensed under different licensing models.
