Astro2020 APC White Paper: Astronomy should be in the clouds

The pith
Astronomy's large new facilities should adopt commercial cloud computing in a coordinated way.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
The paper claims that combining the next generation of big-data astronomical missions with commercial cloud platforms, implemented in a cross-mission coordinated manner, will deliver unprecedented economies of scale in personnel, data collection and management, archiving, algorithm and software development, and science itself.
What carries the argument
Cross-mission coordinated adoption of commodity cloud computing platforms for handling astronomical data.
If this is right
- Shared cloud infrastructure reduces duplicated personnel and hardware expenses across missions.
- Common data archives and processing pipelines accelerate algorithm and software reuse.
- Coordinated curation improves long-term accessibility and usability of multi-mission datasets.
- Science output increases through faster access to larger combined datasets.
Where Pith is reading between the lines
- Smaller research groups could gain access to large-scale computing without building dedicated facilities.
- Standardized cloud interfaces might reduce barriers to international data sharing.
- Real-time analysis pipelines could become feasible for transient events across multiple observatories.
Load-bearing premise
Commercial cloud platforms can meet the technical, security, and cost requirements of petabyte-scale astronomical data without major drawbacks, and independent projects can coordinate effectively.
What would settle it
A major mission such as LSST reports substantially higher total costs or repeated security incidents after migrating core operations to commercial clouds compared with traditional on-premise systems.
read the original abstract
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.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The manuscript is an Astro2020 APC White Paper advocating that commodity cloud platforms (Amazon, Google, Microsoft) be integrated with upcoming large-scale facilities such as LSST, DKIST, and WFIRST. It argues that a coordinated cross-mission strategy for data collection, processing, archiving, and curation will deliver unprecedented economies of scale in personnel, data management, software development, and science.
Significance. If adopted, the proposed shift could modernize astronomical data practices by exploiting commercial-scale infrastructure, potentially lowering costs and accelerating discovery across multiple missions. The paper usefully flags a policy opportunity for the decadal survey process, though its impact is limited by the absence of supporting analyses.
major comments (1)
- [Abstract] Abstract: the assertion that coordinated cloud adoption 'can provide unprecedented economies of scale in personnel, data collection and management, archiving, algorithm and software development and, most importantly, science' is presented without any quantitative cost comparisons, technical requirements analysis, or feasibility metrics; this evidentiary gap is load-bearing for the central policy recommendation.

Authors: This is an Astro2020 APC White Paper, a short policy-advocacy document whose remit is to identify strategic opportunities for the decadal survey rather than to deliver new technical or cost analyses. The economies-of-scale claim is grounded in documented outcomes from other data-intensive domains that have adopted coordinated commodity-cloud strategies. We nevertheless agree that the abstract would benefit from clearer qualification of the prospective nature of the benefits. We will revise the abstract to state that the cited economies are anticipated on the basis of cross-sector precedents and to explicitly recommend that detailed cost, technical, and feasibility studies be commissioned as follow-on work. revision: yes
Circularity Check
No significant circularity
full rationale
This Astro2020 white paper is a forward-looking policy recommendation advocating coordinated use of commercial cloud platforms for large astronomy missions. It contains no equations, derivations, fitted parameters, or self-citations that serve as load-bearing premises. The central claim about economies of scale is an assertion about future coordination benefits, not a result obtained by reducing inputs to outputs via definition or prior self-work. No step matches any of the enumerated circularity patterns; the document is self-contained as advocacy.
Axiom & Free-Parameter Ledger
axioms (1)
- domain assumption Commercial cloud computing platforms can efficiently handle the scale and access patterns of public astronomical surveys without prohibitive costs or technical barriers.
