Three distinct paradigms for sharing computational tools may be observed; the private, shared, and cloud paradigms (fig. ). Private tools are those described in literature, but not made publicly available. Shared tools are accessible when run on local hardware, and cloud tools are accessible for remote usage. Notably, both shared and cloud paradigms may or may not be open source and/or free. This paper focuses on the cloud and shared paradigms, with the aims of promoting use of cloud paradigms to ease collaboration between experimental and computational chemists.
