Notepad MS paint	2 simple mirror clusters with Notepad + Microsoft Paint and with real time file replication and failover.
SQL Server	A mirror cluster with Microsoft SQL Server and with real time database replication and failover.
Application module	Understand what is an application module? Configuration and internal files of an application module: sqlserver.safe example.
VMware Server	A mirror cluster with VMware and with real time replication of a full windows virtual server and failover.
Split brain	Understand network checkers to avoid 2 master servers and to solve the split brain problem.
Message Queuing	A mirror cluster with Microsoft Message Queuing and with real time queues replication and automatic failover.
Synchronous replication	Understand synchronous replication with NO data loss (contrary to asynchronous replication with data loss).
Failback	View failback and reintegration of replicated files without stopping applications.
File replication	2 mirror clusters replicating in the system disk drive C:. Demonstration impossible with shared disk or disk replication solutions.
Apache farm	A farm cluster with Apache and with network load balancing on a virtual IP address and automatic failover.
Network load balancing	Understand network load balancing on a virtual IP address with a cluster of 2 Apache servers. Demonstration without network load balancing boxes and without dedicated servers for load balancing.
Master & slaves dependency	A master module manages shared resources (replicated directories, virtual IP address). Slave modules manage individual start and stop of an application. Applications depend on shared resources managed by the master module. View failover dependencies between slaves and master implemented by SafeKit.
Module dependency	Dependency between an Apache farm cluster and a Microsoft SQL Server mirror cluster. If Microsoft SQL Server cluster is down, then Apache cluster stops and waits for SQL Server restart.
