Experiments in Photon Science at DESY will, in future, undergo significant changes in terms of data volumes, data rates and most important, to fully enable online (synchronous to experiment) data analysis. Primary goal is to support new type of experimental setups requiring significant computing effort to perform controlling and data quality monitoring, allow effective data reductions and, finally, allowing discarding of raw data before storing at all. Different to pure HEP experiments, the software infrastructure has to be standardized and easily (esp. fast) usable by many experiments with different physics goals. We will discuss the plans and work done regarding the hardware infrastructure, the system level middleware (i.e. container, storage connection, networks) and the higher level middleware covering low latency data access and selection (including metadata queries) direct connection the DAQ at detector level to the data processing code (mostly developed by experimentators and running on multiple nodes in parallel. Finally we will show the most current status and first results from initial testing with 'artificial' and real experimental setups.
