Environment establishment for a program in a server system

A server system comprising:

• a subsystem;
• a processor;
• and
• a non-transitory storage medium storing instructions executable on the processor to:
• receive, from a requesting entity, a program input file for a program to be deployed on the server system, the program input file comprising a plurality of parameters, the plurality of parameters comprising a first parameter specifying a provision of fault tolerance for the program, a second parameter specifying a size of a memory heap for the program, a third parameter referring to a dependent program to be used by the program, the dependent program comprising a compiler, and a fourth parameter specifying an update or a restart of the program;
• establish an environment in the server system by sending commands based on the program input file to the subsystem of the server system, wherein the establishing of the environment configures the program with the fault tolerance based on the first parameter, sets up the memory heap for the program according to the size specified by the second parameter, loads the compiler referred to by the third parameter, and updates or restarts the program according to the fourth parameter;
• and
• after establishing the environment in the server system, deploy the program in a first computer node of the server system;
• wherein the subsystem is configured to:
• monitor an operation of the program in the first computer node;
• and
• in response to detecting a fault of the program, trigger failover of the program from the first computer node of the server system to a second computer node of the server system to provide the fault tolerance for the program.

A method of a system comprising a hardware processor, comprising:

• receiving, from a requesting entity, a program input file for a program to be deployed on a server system, the program input file comprising a plurality of parameters, the plurality of parameters comprising a first parameter specifying a provision of fault tolerance for the program, a second parameter specifying a size of a memory heap for the program, a third parameter referring to a dependent program to be used by the program, the dependent program comprising a compiler, and a fourth parameter specifying an update or a restart of the program;
• establishing an environment in the server system by sending commands based on the program input file to a subsystem of the server system, wherein the establishing of the environment configures the program with the fault tolerance based on the first parameter, sets up the memory heap for the program according to the size specified by the second parameter, loads the compiler referred to by the third parameter, and updates or restarts the program according to the fourth parameter;
• and
• after establishing the environment in the server system:
• deploying the program in the environment,
• sending response information to the requesting entity,
• monitoring, by the subsystem, an operation of the program in the environment, and
• in response to detecting a fault of the program, triggering failover of the program from a first computer node of the server system to a second computer node of the server system to provide the fault tolerance for the program.
