A financial technology and crypto hub with Swiss data sovereignty requirements. Zurich teams often run europe-west6 for in-country data residency, with separate non-production environments per regulatory jurisdiction.

Those teams run AWS EKS in non-production the same way everyone does: around the clock, used only during the Europe/Zurich working day. Elastic Kubernetes Service clusters bill every hour they exist, and most of those hours in Zurich are nights and weekends nobody is working.

## The EKS idle problem in Zurich

EKS instances typically bill in the range of $200-5,000/mo per cluster, and in a non-production account the meter runs whether or not anyone is logged on. Scheduling EKS to Zurich working hours removes the hours you were never using.

## How ZopNight helps

ZopNight schedules EKS to stop outside Zurich hours, flags the oversized and idle ones, and reports the result against real usage. It ships 490 built-in audit rules across AWS (216), GCP (127), and Azure (147), starts read-only, and excludes production by default. See it on [AWS EC2](https://zop.dev/zopnight/aws/ec2) and the discipline in [FinOps](https://zop.dev/learn/finops).

## How ZopNight schedules EKS

The loop that does this is deliberately mechanical, and it starts read-only. You connect your cloud provider with a read-only role, and ZopNight discovers every EKS across your regions and accounts. It records a per-action permission verdict for each one, so you can see where it can list a resource but not yet stop it, and you review that inventory, filter it by status or type, and search for the specific resources you care about before anything is scheduled.

Scheduling itself is a cron you write once in plain terms, stop at 7 PM, start at 8 AM on weekdays, pinned to your timezone so the jobs fire at local business hours rather than UTC. A weekly 24-hour grid shows the schedule visually so you catch gaps and overlaps before you save, and an estimate of active versus inactive hours appears before you commit. Resources attach individually or bundle into groups like "dev-cluster" or "staging-db" so a whole environment follows one cadence.

Actions run in dependency order, so a database comes up before the app server that depends on it. When something needs to stay up, an override forces a EKS ON or OFF for a defined window, carries a reason so teammates understand why it exists, and expires automatically so nothing is left running by accident. If a start or stop fails, ZopNight retries up to three times and falls back to a dead-letter queue rather than silently dropping the action, and every state change lands in an audit trail that records whether a schedule, an override, or a specific user triggered it.

## Getting started

Getting started is intentionally low-stakes:

- Connect your cloud provider with a read-only role. Nothing is scheduled or changed at this stage.
- Let ZopNight discover your EKS and review exactly what it found, filtered by account, region, and status.
- Create a schedule in your timezone and attach the non-production resources or groups you want it to cover.
- Watch the first cycle run, with Slack, Teams, or Google Chat notifications on every start, stop, and failure, then layer in idle cleanup and guided rightsizing.

Production stays excluded by default throughout, and because discovery and recommendations are read-only, you can prove the value before you enable a single action.

## Frequently asked questions

### Does scheduling EKS use Zurich local time?

Yes. Schedules run in your timezone, around Zurich working hours.

### Will this affect production?

No. Production is excluded by default; only the non-production EKS resources you choose are scheduled.
