The document discusses using cloud computing to address the large data volumes produced by next generation sequencing (NGS). It notes that a single sequencing machine can now produce 20 gigabases of data per run and that uploading raw sequencing data to the cloud is infeasible due to bandwidth limitations. It proposes moving raw data generation and analysis to the cloud to overcome these issues, with only the final variant call files being transferred back to sequencing centers and research groups for downstream analysis.
