> There are 2 mechanisms which seems to do the same but are totally different:
> * [Kubernetes Rolling Update|http://kubernetes.io/docs/user-guide/rolling-updates/] - replaces Pods in controllable fashon
> * [Infinispan Rolling Updgrate|http://infinispan.org/docs/stable/user_guide/user_guide.html#_Rolling_chapter] - a procedure for upgrading Infinispan or changing the configuration
> Kubernetes Rolling Updates can be used very easily for changing the configuration however if changes are not runtime-compatible, one might loss data. Potential way to avoid this is to use a Cache Store. All other changes must be propagated using Infinispan Rolling Upgrade procedure.
