High-availability data center

A system for recovering software applications after a catastrophic failure, said system comprising:

• at least one subsystem configured to operate a first computing unit at a first location, said first computing unit having a first plurality of software applications executing thereon;
• at least one subsystem configured to operate a second computing unit at a second location, said second computing unit having a second plurality of software applications executing thereon, said second location remotely located from said first location, and said first and second computing units functioning effectively as a single computing unit;
• at least one subsystem configured to monitor a message traffic between said first and said second computing units, said message traffic including one or more predefined error messages;
• and
• at least one subsystem configured to recover said first plurality of software applications on said second computing unit in response to said one or more predefined error messages indicating a loss of said first computing unit, wherein the first computing unit has been determined to be unresponsive in response to said one or more predefined error messages indicating the loss, and wherein one or more of said first plurality of software applications recovered on said second computing unit is identified before occurrence of said catastrophic failure.

A computer-readable medium comprising computer-readable instructions for recovering software applications after a catastrophic failure, said computer-readable instructions when executed by a first computing unit and a second computing unit perform the method comprising:

• operating a first computing unit at a first location, said first computing unit having a first plurality of software applications executing thereon;
• operating a second computing unit at a second location, said second computing unit having a second plurality of software applications executing thereon, said second location remotely located from said first location, and said first and second computing units functioning effectively as a single computing unit;
• monitoring a message traffic between said first and said second computing units, said message traffic including one or more predefined error messages;
• and
• recovering said first plurality of software applications on said second computing unit in response to said one or more predefined error messages indicating a loss of said first computing unit, wherein the first computing unit has been determined to be unresponsive in response to said one or more predefined error messages indicating the loss, and wherein one or more of said first plurality of software applications recovered on said second computing unit is identified before occurrence of said catastrophic failure.
