      Abstract. Resource provisioning is an important issue of cloud com-
      puting. Most of the recent cloud solutions implement a simple way with
      static thresholds to provide resources. Some more sophisticated approaches
      consider the cloud provisioning problem a multi-dimensional optimiza-
      tion approach. However, the calculation effort for solving optimization
      problems is significant. An intelligent resource provisioning with a re-
      duced calculation effort requires smart cloud management methods. In
      this position paper, we propose a case-based reasoning approach for
      cloud management. A case records a problem situation in cloud man-
      agement and its solution. We introduce a case model and a retrieval
      method for previously solved problem cases with the aim to reuse their
      re-configuration actions for a recent problem situation. The case model
      uses the container notion correlated with QoS problems. We present a
      novel, composite similarity function that allows to compare a recent prob-
      lem situation with the cases from the past. During retrieval, the similarity
      function creates a ranking of the cases according to their relevance to the
      current problem situation. Further, we describe the prototypical imple-
      mentation of the core elements of our case based-reasoning concept. The
      plausiblility of the retrieval approach has been tested by means of sample
      cases with simulated data. The original version of this re-submission has
      been published at CLOSER 2016 [Kübler and Minor, 2016].
