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
