What database big companies use when they have to depend on open source to accomplish the following?.
1. High Availability
2. Fault Tolerance/Auto Failover
3. Load Balancing
We are using Ubuntu and MySQL as database. I tried MySQL master-master & master-slave replication and each has some disadvantages and also the MySQL Cluster.
I am looking for best open source database(or the best method of all) for busy web applications which big companies use to achieve High Availability, Auto Failover and Load Balancing.
Your inputs help me a lot in taking best decision. Thank you all!
