Data-bearing members face a higher risk of encountering issues caused by rollbacks, compared to others who utilize different storage methods. This particular write concern prioritizes data longevity over reading speed. The files look something like this: <dbname> <collectionname> 2016-02-08T19-34-44.0.bson

Paravirtualization**: The hypervisor provides efficient hypercalls, and the guest OS uses drivers and kernel modifications to call these hypercalls. Virtualized in Hardware**: Hardware support for virtualization, and near bare-metal speeds. But not all workloads: some are network bound (proxies) and storage bound (databases). ## 5.
