Systems and methods for executing software robot computer programs on virtual machines

A system for executing one or more instances of a computer program, the computer program comprising multiple computer program portions including a first computer program portion and a second computer program portion, the system comprising:

• a first set of one or more computer hardware processors configured to execute a plurality of virtual machines;
• a controller device comprising at least one computer hardware processor configured to perform:
• determining whether a first instance of the first computer program portion is to be executed;
• when it is determined that the first instance of the first computer program portion is to be executed,
• accessing first information specifying a first set of one or more virtual machine resources required for executing the first instance of the first computer program portion;
• determining whether any one of the plurality of virtual machines has at least the first set of virtual machine resources available;
• when it is determined that a first virtual machine of the plurality of virtual machines has the first set virtual machine resources available, causing the first virtual machine to execute the first instance of the first computer program portion on the first virtual machine,
• wherein:
• the first set of virtual machine resources of the first virtual machine includes a user interface (UI) interactions resource which provides the first instance of the first computer program portion, when executed by the first virtual machine on a first computing device, with permission to programmatically control one or more other computer programs, when executed on the first virtual machine on the first computing device, through their respective user interfaces by providing the first instance of the first computer program portion with access to a user interface API of an operating system of the first virtual machine;
• maintaining a message queue for the second computer program portion;
• and
• queuing an output of the first computer program portion into the message queue for the second computer program portion.

At least one non-transitory computer-readable storage medium storing processor executable instructions that, when executed by at least one computer hardware processor, cause the at least one computer hardware processor to perform a method for executing one or more instances of a computer program using a plurality of virtual machines, the computer program comprising multiple computer program portions including a first computer program portion and a second computer program portion, the method comprising:

• determining whether a first instance of the first computer program portion is to be executed;
• when it is determined that the first instance of the first computer program portion is to be executed,
• accessing first information specifying a first set of one or more virtual machine resources required for executing the first instance of the first computer program portion;
• determining whether any one of the plurality of virtual machines has at least the first set of virtual machine resources available;
• when it is determined that a first virtual machine of the plurality of virtual machines has the first set virtual machine resources available, causing the first virtual machine to execute the first instance of the first computer program portion on the first virtual machine,
• wherein:
• the first set of virtual machine resources of the first virtual machine includes a user interface (UI) interactions resource which provides the first instance of the first computer program portion, when executed by the first virtual machine on a first computing device, with permission to programmatically control one or more other computer programs, when executed on the first virtual machine on the first computing device, through their respective user interfaces by providing the first instance of the first computer program portion with access to a user interface API of an operating system of the first virtual machine;
• maintaining a message queue for the second computer program portion;
• and
• queuing an output of the first computer program portion into the message queue for the second computer program portion.
