A playbook execution architecture used to efficiently execute playbooks by distributing the execution of playbook function blocks to multiple independent “worker” sub-processes is described. Each worker process hosts an independent execution environment used to execute playbook function blocks independently from other worker processes, where each worker process can host an execution environment that is the same as or different from execution environments hosted by other work processes, enabling the playbook execution engine to support function blocks written in multiple different programming language versions or programming languages entirely. The described playbook execution architecture enables an IT and security operations application to vertically scale the computing resources used to execute playbooks, provides users with more control over an amount of computing resources devoted to the execution of playbooks, and enables more expressiveness in the types of actions and efficiency of playbooks by providing support for multiple programming languages and programming language versions.
