Improve the Reliability of the Organization’s Resources to Support Remote Education Services

The problem of improving the reliability of the organization's critical access resources is discussed in this article. In the educational sphere, such resources include examination systems, distance learning, videoconferencing, etc. We consider the case of a two-node high availability cluster based on software for configuring fault-tolerant Pacemaker systems Pacemaker and a DRBD distributed file system, which ensures the operation of an organization's website and a MySQL database server in active-passive mode. The configuration is shown for most of the used HA-cluster resources.
