Corosync is a C-based Group Communication System providing a closed process group communication model with virtual synchrony guarantees, plus availability management, a configuration/statistics database, and quorum services. It serves as the messaging and membership layer for high-availability clusters, most notably as the underlying engine for Pacemaker.
Use cases
- build replicated state machines with virtual synchrony guarantees
- implement high-availability clustering on Linux
- detect node failures and manage cluster membership
- manage quorum in a cluster of servers
- run a Pacemaker-based HA cluster
- restart failed application processes automatically
- share configuration and statistics across cluster nodes
When to choose
- you need a proven cluster communication and membership layer for Linux HA
- you are deploying Pacemaker or another HA stack that requires Corosync
- you need quorum enforcement and node failure notification in C applications
When to avoid
- you need a simple single-node service manager like systemd
- you want a cloud-managed orchestration solution rather than self-managed clustering
- your application is not on Linux or does not need cluster-level guarantees
