Open Source

Siennax offers an environment which can host your Open Source applications in a professional manner. Siennax was quick to recognise the significance of the Open Source platform and applications. Its data centers therefore currently have over 200 operational Linux servers, while the advantages of Open Source applications are fully utilised. Siennax provides large-scale, Open Source-based eMail applications for various Internet providers. The insurance sector's Oracle applications for business critical systems and notaries' mortgage file solutions are run on the Siennax Open Source platform.

The Open Source Utility has the following basic characteristics:

  • Servers have the Linux operating system installed. Siennax utilises the latest distributed versions of Redhat, SuSe or Slackware, depending on the application involved.
  • Security is essential: the servers are kept entirely up-to-date with security patches. Access is provided via proxy servers, and is subject to stringent port and protocol rules.
  • The servers are redundant, installed in failover mode, unless the client specifically requires a single-server solution.

The Open Source Utility offers you the following options:

  • Apache-based webservers for HTTP and HTTPS traffic.
  • Proxy servers. These are implemented in triplicate and perform user authentication by means of User IDs and/or certificates. The proxies can rewrite the HTTP header and forward it to the web and application servers.
  • Virtual servers: Several virtual servers can be installed on a single physical server, so as to achieve a cost-effective setup for multiple applications, without any risk of them affecting one another's performance.
  • Firewalls. There is a double firewall layer; in addition to external Cisco firewalls, all servers are protected by internal Linux firewalls. Internal IP addresses are shielded from the outside world by means of network translation.
  • PKI Infrastructure. Siennax offers the Open Source-based option of a PKI infrastructure for the issue of user certificates, based on Verisign.
  • Global File Systems: A Global File System can be installed in Linux for specific applications, for example, to enable several Oracle servers to simultaneously process a single database. The GFS applied is PolyServe.
  • Qmail. Siennax offers you the opportunity to provide customers/users with large-scale 'white labelled' mail facilities. The functionality available comprises not only the common mail protocols (IMAP, SMTP and POP), but also webmail, virus scanning, spam filtering and tapping facilities for the Ministry of Justice. See also eMail.
  • Oracle on Linux. Siennax' Oracle database servers are based on Linux, and offers not only single servers with Oracle 9i, but also the Oracle 9iRAC-platform with failover and load-balancing facilities.
  • MySQL. Siennax also offers MySQL as an option for database storage.
  • OpenLDAP. Siennax offers directory services by means of OpenLDAP, which is used to facilitate not only large-scale mail facilities, but also access to portals and the products and services contain within.

Siennax can provide a Linux server as a so-called managed server. This is a server that has an operating system installed and a number of basic facilities, which you manage yourself in terms of the installation and management of the applications running on the server. See also Managed Server.
