SIOS SANless clusters High-availability Machine Learning monitoring
Definition: With Linux clustering, an application is run on one node, and clustering software is used to monitor its operation. If the software detects an issue, it moves operation of the application to the secondary node in a process called failover.

Definition: IT infrastructure refers to the analysis of data from the hardware, software, network, storage, application and compute resources. IT professionals use IT analytics to ensure their infrastructure is optimized, Service Level Agreements are met and that application performance is maintained for end users.

Definition: Geoclustering is the practice of geographically separating high availability cluster nodes for disaster recovery protection.
In a high availability cluster, important applications are run on a primary server node that is connected to one or more secondary nodes in a cluster. If application operation fails on the primary node, cluster software orchestrates failover of the application operation to the secondary node (s). If the primary and secondary nodes are located in the same geographical location, any risks to that location (eg. fire, flood, natural disaster) threatens the entire cluster.
By locating cluster nodes in multiple different physical locations, a geocluster enables application operation to continue through local downtime incidents and natural disasters.

Definition: Fault tolerance is a level of protection in a computing environment used for mission-critical applications that require >99.999% availability and RTO and RPO of near zero. Fault tolerant systems require an investment in redundant hardware, software, networking and other systems. In these environments, two or more systems operate synchronously – performing compute functions simultaneously, so that in the event of a hardware, software, or network failure, application operation will continue without interruption or dropped transactions.
