Fusion v2

The Fusion file system is a virtual, distributed file system designed to streamline cloud-based data storage and processing. It serves as a bridge between pipelines and cloud-native object stores like AWS S3, eliminating the need for a POSIX interface. Fusion's key features include:

Seamless I/O: Fusion allows for direct read and write access to cloud object storage, simplifying pipeline logic and doubling the throughput compared to traditional cloud storage methods.

Easy installation: Fusion requires no manual installation or management. Its thin client is automatically configured for your pipeline, making it compatible with various cloud object stores.

Reduced data movement: Traditional methods often involve copying data back and forth from local storage to the cloud. Fusion eliminates this need, reducing both data movement and overall runtime.

No shared file systems: Fusion negates the need for expensive and complex shared file systems like Amazon EFS or NFS, instead leveraging the capabilities of cloud object stores for the same functionality at a lower cost.

Performance and efficiency: By cutting out redundant data transfers and allowing for direct access to cloud storage, Fusion accelerates task execution, shortens pipeline runtimes, and reduces cloud-related costs.

Designed to be especially optimized for Nextflow, Fusion automates many tasks that would otherwise require manual intervention, thus maximizing resource use and reducing time-to-results for containerized applications.
