# Notes from the work.

Practical engineering writing from projects: connectivity, device platforms, cloud cost, migrations and the operational details that keep systems boring.

## [Same-SIM satellite IoT: what works today](https://axiointelligence.com/blog/satellite_iot_same_sim/)

Satellite IoT can now run on the same SIM as cellular. Why it's still hard, why many satellite offers don't connect, and what to ask first.

## [What actually sets your z/OS software bill](https://axiointelligence.com/blog/zos_peak_software_cost/)

z/OS software cost is set by the busiest four hours of the month. How the rolling 4-hour peak works, and how to move the batch behind it.

## [How we usually find 30–50% of a cloud bill in the first week](https://axiointelligence.com/blog/quietly_cutting_cloud_bills/)

A field-tested playbook for cloud cost reduction. Where the waste actually hides, what to kill first, and how to put guardrails in so it stops coming back.

## [Migrating clouds without the migration freeze](https://axiointelligence.com/blog/migration_without_downtime/)

Cloud migrations stall when run as one cutover. How we run them as a series of safe, reversible steps, usually with zero production downtime.

## [Infrastructure-as-code that survives the team that wrote it](https://axiointelligence.com/blog/iac_that_survives_the_team/)

Most Terraform repos rot because of the architecture, not the tool. How to structure IaC so a new engineer can ship a safe change in their first week.

## [Kubernetes, the boring way](https://axiointelligence.com/blog/kubernetes_the_boring_way/)

An opinionated default stack for production Kubernetes clusters that are easy to operate, easy to upgrade, and don't surprise you at 3am.

Next note

Stuck on something we should write about?

These notes come from real engagements. If your team is fighting connectivity, a cloud bill or a migration, it’s probably our next note, and a good reason for a scoping call.
