A system, and computer program product for cloud optimization using workload analysis are provided in the illustrative embodiments. An architecture of a workload received for execution in a cloud computing environment is identified. The cloud computing environment includes a set of cloud computing resources. A section of the workload is identified and marked for static analysis. Static analysis is performed on the section to determine a characteristic of the workload. A subset of the set of cloud computing resources is selected such that a cloud computing resource in the subset is available for allocating to the workload and has a characteristic that matches the characteristic of the workload as determined from the static analysis. The subset of cloud computing resources is suggested to a job scheduler for scheduling the workload for execution.
