Solving obsolescence problems using dependable cloud platforms

Juni 2020 | Arthur Martens, Björn Cassens, Lars Schnieder

Products used in railway applications usually have a very long lifespan. At the same time, however, the lifespan of the used hardware is decreasing. Software which was once compiled for specific hardware can be operated using COTS (Commercial Off The Shelf) hardware on cloud platforms without any changes by means of the use of emulators. This constitutes a contribution towards solving existing obsolescence problems in railway applications. This article provides an introduction to cloud platforms and shows the conditions under which cloud platforms can be used for safety-related railway applications...
