Using this information to improve cancer patient outcomes isn’t only a technology challenge.

Cloud is the most economically reasonable way to store and analyze our growing health data corpus.

Cloud provides significant benefits for health data analysis at scale.

• Immediate scaling -- no need to wait to

purchase and install hardware.

• Levels the playing field -- even

researchers at institutions without large compute infrastructure investments can access powerful data and compute resources.

• Extreme durability eliminates or

reduces need for backup copies.

• Multi-tenancy of data means many

researchers can access data without needing to physically copy it. Old model: send data to compute New model: send compute to data

Compute and Data storage platforms allow more researchers to quickly realize the power of cloud.

• Infrastructure configuration and

security/compliance ‘out of the box’.

• Optimized data storage and analysis

methods, across multiple underlying cloud infrastructures.

• Cost monitoring and management.
• Allows researchers focus on science,

not managing computational resources.

The cloud allows multiple researchers to access the same copy of high- value public datasets.

• NCI Cloud Pilots (now Cloud Resources

and the Cancer Research Data Commons) paved the way for secure access and analysis of high value datasets in the cloud.

• Authentication and authorization

mechanisms enable approved researchers to access Controlled data initially from TCGA and TARGET and now an expanding set of data resources.

• Potential to save millions of dollars by

reducing replication of data and speed research by avoiding download times.

Finding, organizing and cleaning data currently accounts for 80% of work performed by data scientists.

Connecting data sets across multiple domains will increase the power of each to drive new discoveries.

• Flexible, semantic data models and

advanced search allows finding data of interest from enormous repositories.

• Can’t be a one-size-fits-all solution - the

properties most interesting for a particular research question tend to be unique

• For example pregnancy exposure is

highly important for birth defect research but not a typical variable for adult cancer research.

Portable and self-contained analysis methods promote reproducibility and speed harmonization of new data with large repositories.

• By describing analysis methods in

Common Workflow Language and packaging tools in Docker containers, the exact routine used for large harmonization efforts can be applied to novel data.

• Implementation of the GA4GH standard

WES allows the same analysis to be performed on multiple platforms.

• Example: TOPMed harmonization

workflow run on GTEX files.

Sharing data and working on it together will speed discoveries.

Collaborative workspaces allow researchers with different expertise to work together in real time.

• Capture the end-to-end ‘research journey’

to facilitate reproducibility and extension

• f results.
• Fine-grained permissions allow different

levels of data and analysis access.

• Multiple communication channels allow

researchers to discuss analyses and results in situ.

Sharing of data and results will reduce re-work, enhance serendipity, and ultimately result in better outcomes for patients.

• Cloud platforms provide a efficient way to

facilitate data sharing since there’s no additional cost for more researchers to access and analyze data.

• Data owners are beginning to make data

broadly available without embargo while ensuring compliance with patient consents - CHOP has led this charge via the CAVATICA platform.

• New technologies facilitate sharing raw

data, methods, and results in a Findable, Accessible, Interoperable and Reusable(FAIR data principles) way.

Data analysis will become a core competency for both researchers and medical professionals.

Platforms and tools must be highly usable with as low a barrier to entry as possible while at the same time enabling power users.

• Reproducibility of analysis journeys also

provides powerful teaching resource.

• Interactive workshops, hackathons, and

training sessions are important to build expertise across individuals with diverse backgrounds.

• Programmatic access methods (APIs)

allow automation and optimization by advanced users while visual interfaces support a broad user base.
