# Apache Karaf Cellar
Apache Karaf Cellar is an Apache Karaf subproject. It provides a clustering solution for Apache
Karaf powered by Hazelcast.
## Overview
Cellar allows you to manage a cluster of several Karaf instances, providing synchronization between instances.
Here is a short list of features:
* **Discovery**: when you install Cellar into a Karaf instance, it automatically tries to discover other Cellar
instances and join the cluster. There is no configuration required to join the cluster, the discovery is made
behind the scene. You can use multicast or unicast for discovery.
* **Cluster group**: a Karaf node could be part of one or more cluster group. In Cellar, you can define cluster group
depending on your requirements. The resources will be sync between nodes of the same group.
* **Distributed Configuration Admin**: Cellar distributes the configuration data. The distribution is event driven and
filtered by group. You can tune the configuration replication using blacklist/whitelist on the configuration
ID (PID).
* **Distributed Features Service**: Cellar distributes the features/repositories info. It's also event-driven.
* **Provisioning**: Cellar provides shell commands for basic provisioning. It can also use an OBR backend or another
provisioning tool such as Apache ACE.
## Getting Started
