[ Services ]

Day by Day delivers Linux, cloud, and platform engineering work for organizations that need reliable infrastructure changes, migrations, automation, or troubleshooting.

We work best when there is a clear problem to solve or a platform improvement to deliver: a review, migration, hardening step, automation rollout, production-readiness improvement, or difficult technical issue that needs clear ownership through diagnosis, remediation, and handover.

PLATFORM ARCHITECTURE

Architecture, modernization, and migration work for Linux-based platforms: Kubernetes clusters, OpenStack clouds, public cloud, private cloud, VPS, and dedicated bare-metal environments. We evaluate capacity, reliability, cost, and operational risk before committing to a design.

BUILD & AUTOMATION

Repeatable provisioning, configuration management, and delivery workflows using Ansible, Puppet, Ansible Tower/AWX, Cobbler, GitHub, and GitLab. The output is automation that can be reviewed, reused, and handed over—not scripts that only work once.

OPERATIONS & RELIABILITY

Reliability work for production platforms: runbooks, monitoring improvements, failure-mode review, high-availability changes, production-readiness fixes, and root-cause analysis across Linux, storage, networking, web, database, and platform services.

TROUBLESHOOTING & MIGRATION

Focused troubleshooting, upgrade, and migration work where the problem or path forward is unclear. Work can cover performance regressions, upgrade breakage, hardware/software interaction, Kubernetes and OpenStack migrations, and Linux service transitions across web, database, identity, VPN, and network services.
