Day by Day is Gerben Meijer’s independent Linux and open-source company, founded in 2005. We design, modernize, migrate, automate, and troubleshoot production infrastructure: from Linux and storage to Kubernetes, OpenStack, cloud platforms, and high availability.
The work is practical and outcome-focused. We prefer clear scope, useful documentation, and a clean handover over open-ended consultancy without a defined result.
See the services overview for the areas we work in, or contact Day by Day to discuss a concrete platform, migration, automation, or troubleshooting need.

Day by Day was founded in 2005 by Gerben Meijer as an independent Linux and open-source company for production infrastructure work.
The company helps teams make concrete platform improvements: modernization, migration, automation, troubleshooting, storage, networking, Kubernetes, OpenStack, and high-availability work that has to hold up in production.
Work usually starts with a clear platform problem or change: a migration that needs planning, automation that needs to be reliable, an upgrade that carries risk, or a production issue that needs root-cause analysis.
The goal is practical ownership of the result: architecture that can be built, automation that can be maintained, documentation that is useful, and handover that leaves the operating team in control.
