FAQ

Answers to questions that come up regularly — especially about design decisions that may seem surprising at first.

How Swiss is Deploio really?

Your applications, databases, and storage run in Nine's data centers in Switzerland. There are currently two caveats you should be aware of:

• The control cluster runs on Google Cloud Platform. The Deploio API (nineapis.ch) points to GCP because the k8s control cluster runs there for historical reasons. This dependency has no influence on the data integrity of your applications: workloads and their data stay in Switzerland, only the management plane runs on GCP. Nine is aware of this limitation and is working on migrating this system to its own infrastructure.
• 24/7 support involves a Canadian subsidiary. Nine provides around-the-clock support through a subsidiary in Canada. This takes advantage of the timezone shift. The details are listed in Appendix 3 of the Data Processing Agreement. Opt-out is possible for other Nine products but not for Deploio yet.

Why do I have to set the S3 region to us-east-1?

The S3 protocol requires a region for request signing, so S3 clients refuse to work without one. Deploio's object storage accepts the S3 default value us-east-1 — it is purely a protocol-level label and says nothing about where your data lives. The buckets are hosted in Switzerland, operated by Nine.

See the Active Storage (Rails) and Object storage (PHP) guides for configuration examples.

Why is my app down during maintenance windows?

Nine defines maintenance windows to introduce security patches and upgrades. You can prevent these downtimes by configuring at least 2 replicas for your app.

Why can apps not be renamed?

This is a restriction of the underlying k8s infrastructure. It's a good old Swiss compromise, a tradeoff between using autogenerated cryptic handles and human-readable identifiers.

But you can label an app with a display name to help you identify it.
