While a lot of people use shell scripts as an analog to a batch file in MSDOS, it can do so much more than that. Contrary to what you might think after a casual glance, it is entirely possible to write scripts that are reliable and robust enough to use in many embedded systems on a Raspberry Pi or similar computer.
How to Size Your MongoDB Clusters: Overprovisioning remains a rampant problem, which companies such as Qubole aim to solve through automation.
