Example methods and computer systems for cloud environment configuration based on task parallelization. One example method may comprise: obtaining a task data structure specifying execution dependency information associated with a set of multiple configuration tasks that are executable to perform cloud environment configuration. The method may also comprise: In response to identifying a first configuration task and a second configuration task that are ready for execution based on the task data structure, triggering execution of the first configuration task and the second configuration task. The method may further comprise: in response to determination that the first configuration task has been completed, identifying third configuration task(s) that are ready for execution based on the task data structure; and triggering execution of the third configuration task(s) by respective third compute node(s).
