Computing device providing fail-safe execution of a service

A computing device comprising:

• non-volatile memory storing a service, the service comprising instructions executable by a processor of the computing device;
• volatile memory;
• and
• the processor for:
• generating a fail-safe file and storing a reference to the service in the fail-safe file;
• storing the fail-safe file in the non-volatile memory with a read-write access right for users of the service;
• launching an instance of the service associated to the fail-safe file, the launching comprising copying the instructions of the service from the non-volatile memory to the volatile memory and executing the instance of the service by executing the instructions of the service copied into the volatile memory;
• storing data generated by the execution of the instance of the service in the volatile memory;
• copying critical data to the fail-safe file associated to the executed instance of the service for permanent storage in the non-volatile memory, the critical data consisting of only some of the data generated by the execution of the instance of the service and stored in the volatile memory;
• and
• upon occurrence of an interruption of the executed instance of the service, launching by the processor a new instance of the service associated to the fail-safe file, the new instance of the service using the critical data copied into the fail-safe file;
• wherein the critical data copied into the fail-safe file are critical for starting the new instance of the service from a state identical to a state of the executed instance of the service before the occurrence of the interruption.
