Open Source Platform
The Bunker’s Ultra* secure, Hardened Open Source Platform is built using the world’s leading open source software solutions, including:
Infrastructure Solutions
FreeBSD Operating System
The Bunker uses FreeBSD as a preferred operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon 64, and EM64T), Alpha/AXP, IA-64, PC-98 and UltraSPARC® architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley.
Wackamole
The Bunker uses Wackamole to help make server clusters highly available. Wackamole manages virtual IPs that should be available to the outside world at all times. It ensures that a single machine within a cluster is listening on each virtual IP address that Wackamole manages. If it discovers that particular machines within the cluster are not alive, it will immediately ensure that other machines acquire these public IPs. At no time will more than one machine listen on any virtual IP. Wackamole also works toward achieving a balanced distribution of number IPs on the machine within the cluster it manages.
OpenBSD
The Bunker uses OpenBSD to provide a free, multi-platform 4.4BSD-based UNIX-like operating system. OpenBSD efforts emphasize portability, standardization, correctness, proactive security and integrated cryptography. OpenBSD supports binary emulation of most programs from SVR4 (Solaris), FreeBSD, Linux, BSD/OS, SunOS and HP-UX.
CARP and Pfsync
The two main components provided by OpenBSD are CARP (the Common Address Redundancy Protocol), which allows a backup host to assume the identity of the primary and pfsync, which ensures that firewall states are synchronised so that the backup can take over exactly where the master left off and no connections will be lost.
Gentoo Linux Operating System
The Bunker deploys Gentoo Linux, a special flavour of Linux that can be automatically optimized and customized for just about any application or need. Extreme performance, configurability and a top-notch user and developer community are all hallmarks of the Gentoo experience.
Webserver Solutions
Apache
The Bunker uses the Apache HTTP Server Project to provide a secure, efficient and extensible server that provides HTTP services in sync with the current HTTP standards.
Mod_backhand
The Bunker uses mod_backhand to enable seamless redirection of HTTP requests from one web server to another. This redirection can be used to target machines with under-utilised resources, thus providing fine-grained, per-request load balancing of web requests. Mod_backhand is a drop-in module for the Apache Web Server and provides a turnkey solution for intra-cluster redirection of HTTP on a per-request basis. The redirection is based on various system resources available within the cluster. This service is provided seamlessly, preserving remote host information for access/authentication purposes. As with the methodology of Apache, the redirection mechanism can be enabled or disabled for individual directories.
Tomcat
The Bunker uses Tomcat, the servlet container that is used in the official Reference Implementation for the Java Servlet and JavaServer Pages technologies. The Java Servlet and JavaServer Pages specifications are developed by Sun under the Java Community Process.
Tomcat is developed in an open and participatory environment and released under the Apache Software License. Tomcat is intended to be a collaboration of the best-of-breed developers from around the world.
Database Solutions
MySQL
The Bunker uses MySQL for its standard database implementations. MySQL is the most popular open source database and the fastest growing database in the industry. This is based on its dedication to providing a less complicated solution suitable for widespread application deployment at a greatly reduced total cost of ownership.
Managed Tape Back-Up Solutions
Bacula® - The Network Backup Solution
The Bunker utilises Bacula - a set of computer programs that permits us to manage backup, recovery and verification of computer data across a network of computers of different kinds. In technical terms, it is a network based backup program.
