Success Stories

Data Centre with Zero Downtime Architecture


2007-2009 We develop a data centre concept for a leading online payment provider and also play a major role in its implementation.

The requirement:

“Zero Downtime” for all business-related applications. This includes critical database and middleware updates as well as application releases. Due to legal regulations, the loss of even a single customer request will not be tolerated. This also applies to frequent switches between the various data centers. In order to strengthen the company’s global competitive edge, the new concept focuses on low production costs, manageability, quick response to changes in requirements, flexibility.

Oracle Real Application Cluster (RAC)


2007 For a German provider of online payment solutions we implement a new, Oracle RAC based system that runs on Linux with Intel hardware.

The requirement:

The current SPARC/Solaris based system can no longer handle the increasing transaction load. This affects the stability of the system, among other things. The “operations” and “development” departments are finding themselves being increasingly forced to work on Query levels as well as with workarounds. The central database is essential for the customer’s business operations.

Online Payment Solution

realistic design element. e-commerce

2006-2007 We create an extensive Internet payment solution for a leading online payment provider and also play a major role in its implementation.

The requirement: 

The product launch time plays a crucial role in its economic success. Therefore, this innovative product must be developed within an extremely short time frame.



In 2010, Raiffeisen Bank International AG (RBI) hired ByteSource to increase the capacity for the roll-out of our retail risk management platform but also to add creativity for solving existing and upcoming issues. After the initial phase, ByteSource quickly became an important part of the project team.

Internet of Things, Gigaset elements


In January 2013 Gigaset chose Bytesource as partner for the development of a new state-of-the-art web frontend for their brand new home automation solution ( The partners were facing a very tight time-frame, continuously evolving business requirements and teams as well as infrastructure that were distributed around Europe.

Bytesource took on the challenge and played a leading role in setting up Scrum as an agile development process.

J2EE – Coaching and Architectural Design


2005-2006 We provide J2EE architecture consulting for a leading international technology company based in Germany.

The requirement:

The education and training of approximately 70 software developers in the areas of Enterprise Java, handling transactions, data persistence, asynchronous communication, etc. We also implement test driven software development (TDD) in combination with the corresponding tools. To ensure data persistence, we design and develop an OR mapping layer for a telecommunications specific database system.

SAS Agile Infrastructure


SAS is a powerful software widely spread for statistical calculations. It is mostly used in business department, but as usage grows, more IT support is required (stable data streams, regular reports …).

And here IT staff often meets some challenges in order to run SAS as professional as i.e. Java environments. Often seen as painful is deployment (specially if SAS metadata is used) and the installation of a full SAS stack.

Analytical Data Warehouse


2002-2005 We develop a data warehouse for a major Austrian bank to support their cross selling business activities.

The requirement:

The first production version of the data warehouse is already available after one month of development. It is based on an Oracle database and runs on Unix. A comprehensive cost analysis and a “Proof of Concept” are conducted by the customer in order to compare the recommended solution with the one used thus far (based on a mainframe system).

Group Data Warehouse


2005-2006 For a major Austrian bank we assume the responsibility to design a new group data warehouse as a base for all Basel II reporting tasks.

The requirement:

On the system architecture side, we redesign the already existing SMP-based system and evaluate the new Linux based version in comparison to the Unix based one. The new solution distinguishes itself through increased stability and performance.
