Abstract: The amount of genomics data is increasing at a rapid pace. This leads to a situation where high-throughput data processing is needed to efficiently mine insights from the increasingly abundant genomics data. However, bioinformatics workflows/jobs
typically take large input files (e.g., hundreds of GB), resulting in jobs having long execution times.</div>

This thesis work seeks to answer the following research question: "How to ensure X% deadline satisfaction when scheduling bioinformatics workflows in hybrid clouds?". To address the problem, this thesis presents a novel hybrid cloud scheduler that significantly
reduces deadline miss rate at no or minimal extra cost. The new scheduler consists of two main components: 1) an accurate execution time predictor for bioinformatics workflows and 2) a novel scheduling policy for ensuring a high statistical guarantee of completing
job executions on spot instances leveraging spot lifetime distributions and job duration prediction. </div>

In this thesis, I developed a high-fidelity simulator that accurately resembles the behaviors of bioinformatics workflows on hybrid cloud environments composed of on-premise and cloud machines. The proposed scheduler was modeled on top of the high-fidelity
simulator and evaluated using large-scale, real-world production traces from one of the leading genomics research centers. The evaluation results show that the new scheduler successfully reduced deadline miss rates and/or cost compared to several baseline
scheduling policies. Finally, the thesis outlined future research directions for refining and implementing the scheduler on production-level genomics processing systems.</div>
