The scheduling objective is to map the workflow application to the VMs pool at available cloud datacenters such that the overall processing time (makespan) is to be minimized and average cloud utilization is maximized.

TimeMint algorithm is capable of scheduling large size workflows in heterogeneous multi-cloud environment. The results remarkably show that the algorithm increases the workflow efficiency in terms of makespan, speed-up, schedule length ratio and average cloud utilization. This is how TimeMint reduces the OpEx.
