  • Minimize upfront planning and simplify

decision making with Modular+ architecture.

  • Easily transition to or leverage public cloud –

Azure, AWS or Google Cloud Platform. Bring- your-own-subscription (BYOS) of SUSE Linux Enterprise 15.

  • Enhance security with disconnected
  • ffline installation.
  • Simplify IT operations with the new

unified installer.

Server-side Components

  • A Server that:
  • Stores all source in a revision

control system

  • Stores all built binaries
  • Calculates the need to rebuild

packages

  • Acts as a database for various

queries

  • A Set of Client Tools, API:
  • “osc” command line interface
  • Optimized for handling sources
  • Run builds on your local machine

the same as you would do on the server

  • Web UI
  • Optimized to see current status
  • Manage requests for changes
