A challenge on IT sector is capabillity to provide a highly available and highly reliable system. Every system development want to have a 100% availability, in other words, without downtime at all. But the fact said those thing can’t be reached because the cost to provide a high spesification system is too high. Solution on this research was by providing data and process redundancy. Data redundancy was achieved by having data replication on each server. Process redundancy was achieved by using cluster. The cluster was also used as automatic failover. Automatic failover provides capability to move automatically to redundan server if failure occure. To verify system capabilities was used functional testing and load testing. Based on the test result, system could perform its functionality on a normal condition or after failure. Beside that system also could served every transaction that came continuesly. Each kind of database operation was executed 24 hours and system could serve it without failure

Kata Kunci : high availability; high reliability; server basisdata; replikasi; failover
