  Commodity cloud computing, as provided by commercial vendors such as Amazon,
Google, and Microsoft, has revolutionized computing in many sectors. With the
advent of a new class of big data, public access astronomical facility such as
LSST, DKIST, and WFIRST, there exists a real opportunity to combine these
missions with cloud computing platforms and fundamentally change the way
astronomical data is collected, processed, archived, and curated. Making these
changes in a cross-mission, coordinated way can provide unprecedented economies
of scale in personnel, data collection and management, archiving, algorithm and
software development and, most importantly, science.
