abstraction layer designed for High Availability use cases, where redundancy,

your application.
Kronosnet is the new underlying network protocol for Linux HA components
(Corosync), that features ability to use multiple links between nodes,
active/active and active/passive link failover policies, automatic link
recovery, FIPS compliant encryption (nss and/or openssl), automatic PMTUd and
in general better performances compared to the old network protocol.")

@item A simple availability manager that restarts the application process when
it has failed.
@item A configuration and statistics in-memory database that provide the ability
to set, retrieve, and receive change notifications of information.
@item A quorum system that notifies applications when quorum is achieved or
lost.

(synopsis "Scalable High-Availability cluster resource manager")
(description
"Pacemaker is a high-availability cluster resource manager.
It achieves maximum availability for your cluster services (a.k.a. resources) by
detecting and recovering from node- and resource-level failures by making use of
the messaging and membership capabilities provided by Corosync.
It can do this for clusters of practically any size and comes with a powerful
dependency model that allows the administrator to accurately express the
relationships (both ordering and location) between the cluster resources.
Virtually anything that can be scripted can be managed as part of a Pacemaker cluster.")
