# Planning for installation

Keyless Backend is a Kubernetes-based solution. It is compatible with Openshift 4.10 and is provided through a series of Helm charts. The installation process is intended for system administrators that have expertise with Helm and Kubernetes.

The Keyless Backend service is an enterprise-grade solution. It is provided in a flexible format, allowing overrides to adapt to various customer deployment scenarios. The only real hard dependencies are Kubernetes (on x86\_64 architecture), PostgreSQL and an S3-compatible storage. More details are provided in the requirements section.

To ensure a functioning system, customers should plan for an adequate number of Kubernetes pods. They should also ensure sufficient storage and connection capacity for both the PostgreSQL database and the S3 layers and ensure observability.
