Open Source Data Center Solutions | We have years of experience in design, construction and operation of major IT applications and platforms for Web sites based on open source software. Hence we understand that a data center’s most important feature is scalability- they need to handle more load without downtime. We provide open source solutions for load balancing, clustering, databases, application servers and security which grow with your needs. |
Network & ServerCreate efficient and trouble-free networks
Networks and servers are the foundations of all IT applications and processes. Only when this base is perfect and performing at top condition, can applications and processes run smoothly. Capacity plan your network, to ensure it can expand with your platforms without downtime. We can assist from the onset, so you have the right servers of the right CPU model and memory - all configured for redundancy. Connect mobile employees and geographically scattered offices to a VPN (Virtual Private Network) with open source solutions cheaply and securely. OpenVPN and Openswan offer secure and reliable solutions based on Linux for every corporate network. Working both open source and mainstream solutions, we implement networks tailored to your applications and needs that are both cost effective and efficient.

ClusteringImplement clustered servers for high availability
Clustered servers offer redundancy and high availability in your network. In principle, a back up server for each server- one active master and one passive slave. The slave monitors the master in stand-by and replaces it automatically in the event of any failures. This ensures the highest availability, so failures are never even noticed. It is usually excessively expensive, with highly specialised hardware and software, associated license costs and annual maintenance fees. By combining Linux the free operating system, standard hardware with specialized security solutions- we offer cluster solutions at a fraction of the price.

High AvailabilityBundle measures to increase availability
To ensure the constant availability of your entire network as well as every single server, application, process, we offer a complete service. The fool proof solution that combines a redundant network, clustering and load balancing. Important servers are connected by two different network cards to two different switches and are configured by bonding or trunking. Furthermore, the servers are clustered through virtualisation to use minimal hardware whilst ensuring a component takes over from another failed one. Load balancing offers even higher network performance and redundancy in minimising the risk of a server fall out. To ensure the consistent high availability of the setup, we test every 3 months and major configuration change. This setup ensures the accessibility of the server despite a switch or network failure, or even a pulled cable.

Load balancingShare work load between servers
Easily deploy efficient and scalable application platforms online by distributing queries from URLs to multiple servers. Scaled linearly, the capacity of the platform correlates simply to the number of servers as no online communication needs to take place. In effect a virtual server is created as the Loadbalancer which correspond to the IP address and port number, hence representing an application. The Loadbalancer directs queries to the real servers by VAT or direct routing, depending on the various capacities or functions. The real servers then respond to the query directly to the client or via the Loadbalancer. As the Loadbalancers are also potentially single points of failure, we cluster them too for redundancy. Furthermore we offer dynamic load balancing. This means automatic adjustments of the load balancing to immediately remove failed servers or distribute load away from slower or weaker servers.

VirtualizationYield more from hardware resources
Depend less on hardware while getting more out of each resource. Virtual servers are not coupled to any specific hardware so are simpler to maintain and are easily be moved between platforms without driver problems. Since multiple virtual servers can be installed on one physical server, its efficiency is multiplied in use. This perfectly suits services which require a dedicated server but lower output. Reorganisation is also simplified. When an application promptly needs more power, virtual servers can be quickly configured faster than new hardware for a real server can be purchased and installed. Simply put, virtualisation saves on hardware and hence power costs which can amount to 60% of data center operational costs.

Storage solutionsProvision of central storage or complete SAN solutions (SysAdmin, Networking, Security)
More data, more pictures, higher resolutions, more multimedia on the internet and the more regulations on historical data availability means a company can never have enough data space. We offer a central storage space for scalable applications, so as a platform grows you can be assured all components and servers have access to a common data space – images, texts, source code and all.

FirewallsSafeguard network areas
Secure various network areas against one another by installing firewalls to filter data traffic between segments, which work off permission rules you define. We offer firewalls based on open source software in combination with normal PC hardware for many advantages over expensive hardware solutions. Hardware firewalls for high flexibility and availability can easily cost €90,000. With a redundant setup, Shorewall can be implemented at just €8,000. Open source also offers flexibility to custom the firewall availability, number of interfaces and pick the hardware platform you already have experience working with. Extensions, upgrades and repair are then also easier to find. In a nutshell- more performance for less money.

DatabasesRobust databases, cluster and replication
Databases are the backbone of every major application, and unfortunately often the bottleneck. It takes special expertise to design, install or optimise a reliable and powerful database. Our consultants specialise in high performance databases and database clusters. We have constructed customer platforms which service more than 12 million page impressions per 24 hours. We know that fast growing environments call for constant modification and performance optimisation.

VoIPTelephone through IT networks
Do away with telephone network cabling, systems and rates while reducing your telephone costs through Voice over Internet Protocol technology. More flexible and mobile, voice data is transmitted through normal network technologies and are rerouted at any point on the Earth, additionally encrypted and redundantly distributed. Thus, telephones and virtual extensions are no longer location bound. When combined with cluster technology, VoIP is also fail safe and has less specialised hardware to repair. With many additional features such as voice menus and fax gateways, VoIP is the robust, yet cheap alternative to classical telephones.
