In the previous chapters, we saw Cellar as a provisioning clustering solution; the actions performed on resources from one node create cluster events that are sent to the other nodes; these nodes then react accordingly.

In this chapter, we will cover the following topics:
What DOSGi is and a use case
The Cellar DOSGi implementation
A complete example using Cellar DOSGi
