Singularity Enterprise

The initial investment for containerizing production environments is exceedingly minimal. In transitioning proof-of-concept investigations into production use cases, and in addition to increased levels of committed resources, it soon becomes evident that ancillary services are required to ensure the success of production deployments. For this reason, Sylabs™ has developed a portfolio of three hosted services to ensure Singularity containers can be easily created, secured, and shared in order to better enable production use.

Fully integrated with the Singularity command line, available via the Internet or customer hosted, these container services are seeing rapid uptake from savvy organizations seeking to rapidly accelerate adoption and use of containerization in their data centers, clouds, and even at the edge.
