bds combines the simplicity of scripting and the power to run on any computer. After all, a laptop, a cluster, a cloud and a datacenter are just computers. You should not need different frameworks to run program on each of them.
No need to spin instances or wait for cluster queues while developing and debugging. The same script runs without changes on laptops, clusters, or cloud. So you can develop pipelines faster and easier. Turn arround times are faster, debug times are shorter.
Once your script is ready, you just run it ont the cloud. No need to change the script. Coordinating jobs, spinning instances, logging, all done transparently.
