In this talk I will share the great experience we have of packaging, deploying, publishing and distributing software via GNU Guix of a complex web service that has multiple servers under http://genenetwork.org/. I will also discuss the work we are now executing on creating 'channels', reproducible build-systems and non-root installations and moving forward on putting Guix in containers, using work flow engines, so that jobs can run on distributed systems, such as Arvados.
