- Storing 90 days of video from 10,000 cameras, on site
The arithmetic, the MinIO topology and the lifecycle rules behind hyperconverged edge storage for large-scale video, and how it compares with S3, including the swap path.
- Devices pull intent: why edge nodes should poll instead of taking commands
A control plane with no inbound path to the device. The intent document, the API contract, the reconcile loop, enrolment without shared secrets, and where the model hurts.
- Cutting a cloud bill by 70% without a finance meeting
Cost is an engineering signal. Billing data grouped by owner, GPU node pools that scale to zero, environments that switch themselves off, and what each of those costs you back.
- Keyless across clouds: identities instead of key files
Two clouds that trust each other with no stored credentials. The pattern, the Terraform for both sides, the token exchange, and what it costs you.
- Green CI, stale prod: assert the outcome, not the exit code
A pipeline that ends by checking what is actually running. The failure it prevents, the version endpoint, the verify step, and the same idea applied to infrastructure with zero-diff gates.
- Importing a hand-built cloud into Terraform without breaking it
Putting a few hundred live cloud resources under code without downtime, using zero-diff gates. A generic playbook.
