Intelligent software deployment on an IaaS platform

摘要

A method obtains a task tree for a deployment job to deploy application(s) to a compute infrastructure, the task tree indicating tasks to execute the deployment job. The method also obtains script(s) and configuration information for executing the script(s). The method simulates an installation process using the task tree and provides a refined task tree. The method invokes the installation process of the deployment job, the installation process including execution of the tasks of the deployment job and using the refined task tree. The method backtracks the installation process after recognizing an error, pausing the installation process and applying an adjustment to the refined task tree to resolve the error. The installation process resumes from a prior point using the refined task tree with the applied adjustment. Based on successful completion of the installation process, the method provides an adjusted refined task tree as an optimized task tree.
