Software for Clustering

1 minute read

Apache Zookeeper

Apache ZooKeeper is a centralized service required for clustering.

  • Apache ZooKeeper is a critical part of the clustering architecture. You must use ZooKeeper Version 3.4.6 or later to maintain and synchronize group services in the CloudBees CD cluster. CloudBees CD includes a tool called ZKConfigTool, which you can use to populate ZooKeeper quickly with CloudBees CD configuration information.

  • Exhibitor can be used with ZooKeeper to monitor the synchronization between the ZooKeeper nodes. This software is not required to implement a CloudBees CD cluster configuration, but can provide instance monitoring, backup, recovery, cleanup and visualization services. See the Exhibitor documentation at https://github.com/Netflix/exhibitor.

Load Balancer

You must use a load balancer in a CloudBees CD cluster. You can use any load balancer or load-balancing software for a cluster as long as the load balancer acts as an SSL endpoint and supports returning HTTP redirections.

Transport Layer Security (TLS) has replaced Secure Sockets Layer version 3.0 (SSLv3) on the CloudBees CD server and the CloudBees CD web server.
