Topics

The areas I write about, with the list of posts in each.

Container platforms run declaratively: cluster, networking, data, and deployment from a repository.

Ansible, playbooks, workflows and ITSM integrations. Repeatability instead of heroics.

Active Directory, Hyper-V, Group Policy and everything that still runs on Windows in real companies.

Logs, metrics, alerts. What to collect, what to ignore, and how not to drown in data.

Pipelines, image builds, releases. From commit to running application with no manual steps.

Segmentation, DNS, firewalls, load balancing and links. The foundation nobody remembers until it fails.

Privileged accounts, hardening, email, endpoints. Security as a property of the environment, not a product.

The 3-2-1 strategy, RPO and RTO, restore tests. A backup is worth exactly as much as its last successful test.

Exchange Online, filtering, quarantine, sender authentication. The one service every employee sees.

Group Policy, endpoint management tools, updates, standardisation. Hundreds of machines, one target state.
