Following in the footsteps of Debian and Maven, we're very pleased to announce that RPM is the latest package format to support upstream caching and proxying.
With Upstream Proxying, Cloudsmith will allow RPM clients configured to use your repository to see and download your existing repository packages, as well as all those defined in any connected upstream repositories.
When upstream caching is turned on, fetches made for packages resolved to an upstream can be cached and synchronised to your Cloudsmith repository - helping to protect your software dependencies from outages, improve visibility, and apply fine-grained access controls for your teams, customers and users.
Check out more our blog, where Dan goes into depth on how to configure and use an RPM upstream.
