[ About ]

Day by Day is Gerben Meijer’s independent Linux and open-source consultancy, founded in 2005. We help teams design, run, migrate, and troubleshoot production infrastructure: from bare metal and networking to Kubernetes, OpenStack, cloud platforms, automation, storage, and high availability.

The work is practical and hands-on. We combine architecture with implementation, root-cause analysis, migration planning, and platform operations, so decisions are tested against how systems behave in production.

See the services overview for the areas we work in, or contact Day by Day to discuss infrastructure review, troubleshooting, migration, or operational support.

THE COMPANY

Day by Day was founded in 2005 as Gerben Meijer’s independent Linux and open-source consultancy. The focus is production infrastructure: systems that need to be designed well, operated carefully, migrated safely, or fixed when the failure mode is unclear.Work ranges from Kubernetes and OpenStack platforms to cloud/VPS environments, automation, storage, networking, and high availability. The approach is direct and practical: understand the risk, make the trade-offs explicit, and implement what the platform actually needs.

THE WORK

Engagements can start with an independent review, a migration plan, a production incident, or a platform build-out. Recent work includes Kubernetes and OpenStack operations, software-defined storage stabilisation, high-availability Linux service migrations, DevOps automation, and managed Linux device environments.The common thread is ownership of the technical outcome: architecture that can be implemented, automation that can be reviewed and repeated, and operational handover that leaves teams with a system they understand.
