APPUiO is a Kubernetes-based container hosting platform that relies on Red Hat OpenShift. Teams can run containerised software written in languages such as PHP, Python, Java, Go or Rust and add services such as databases, caches and queues. Projects and environments are separated for access control and billing, ordering is self-service, builds and deployments can be automated, and security features include SELinux, Let's Encrypt and two-factor authentication. It is a managed platform and a product of VSHN AG.
VSHN is based in Zurich, Switzerland, and APPUiO states that data can be stored in ISO-certified data centres in Switzerland. Switzerland is not an EU member state but belongs to EFTA. VSHN says open standards and open source are the basis of the platform and publishes open-source projects such as K8up and Project Syn; whether APPUiO itself is open source is not stated. For a European organisation this means a Swiss-operated service built on OpenShift, with hosting in Switzerland.
