to run the same resource on multiple nodes. For example, webpage server or cluster file system. The ability to run the same resource on multiple nodes in one of two different modes. For example, synchronize resources and targets. Pacemaker does not need Distributed Lock management programs. Configurable behavior when arbitration is lost or multiple partitions are formed.

each executable process is allocated one piece. A single processor can run only one process at any given time. If the time slice or time limit (quantum) of the currently running process expires, the process can be switched. Time-sharing depends on scheduled interruption. Specifically, it is the well-known timer_interrupt interrupt service function in the arch/i386/kernel/time. c file we mentioned in the Interrupt Processing topic. Therefore, it is transparent to all processes and no additional

Apiserver high availability that need to be summarized here, and we've got some kind of apiserver service available here through Corosync + pacemaker software, This is because Apiserver is a stateless service that allows different nodes to exist at the same time. And Scheduler,controller-manager in the cluster can only be opened in one host, here we can start Controller-manager and scheduler just add--leader-elect=true Parameters can be started at th

considerable operational overhead. SQL Server 2017 introduces a read scale availability group that does not require clustering.If the business requirement is a resource that transforms a task-critical workload running on the primary replica, the user can now use read-only routing or connect directly to a readable secondary replica. Without the need to rely on integration with any clustering technology. These new features are supported by SQL Server 2017 on Windows and Linux platforms.This is no

the Maxscale, each connection from the client, the connection to the backend server, and each listener is assigned a DCB, The status statistics for these connections are done by these DCB. Each DCB does not have a specific name for the query, but instead uses a unique memory address directly. Maxscale's MHA The official recommendation is to use LSYNCD or Corosync-pacemaker. Personally think that some of Maxscale's ideas are good, including Percona
