Technical characteristics
When creating this system we paid great attention to the system stability as to possible failures. System stability is achieved due to the following factors:
- Support of 50 000 users on one server
- Possibility of system expansion (+50 000 users for each server)
- Regular data backup, each 24 hours, with its transmission to the third server for storage
- Use of disk arrays, type RAID-1, to ensure fault-tolerance on the level of data storage devices
- Constant monitoring of server condition with notification of competent people about possible problems
- Possibility of hot swapping of the server in case of its failure
