Canonical’s Landscape |
The standards-based APIs are the same between all OpenStack deployments, and they enable customer and vendor ecosystems to operate across multiple clouds. The site-specific infrastructure combines open and proprietary software, Dell EMC hardware, and operational processes to deliver cloud resources as a service.
The implementation choices for each cloud infrastructure are highly specific to the requirements of each site. Many of these choices can be standardized and automated using the tools in this Reference Architecture. Conforming to best practices helps reduce operational risk by leveraging the accumulated experience of Dell Technologies and Canonical.
