The 9th International dCache workshop is an event in a series of workshops, meant to build and maintain an active dCache community and to strengthen the relationship between dCache system administrators and dCache developers. We will will have many very interesting topics, amongst them dCache and Elastic search Logstash Kibana (ELK), some interesting HowTos and a very interesting concepts, where dCache is used in industry to create products that might also be interesting to T1 and T2 centres. Also dCache and ownCloud will be a topic during this year. Last but not least we will have lively discussions on where to go next and present how far we have gotten with our roadmap. This year's workshop is organised by dCache.org and the dCache German support group.
