## What it is
Ubicloud is an open-source IaaS cloud platform that provides elastic compute (VMs), block storage, networking, load balancing, managed PostgreSQL, Kubernetes, AI inference, and IAM on top of bare metal providers like Hetzner and Leaseweb. It can be self-hosted via its Ruby control plane or used as a managed service that claims 3-10x cost reductions versus AWS, Azure, and Google Cloud.

## Use cases
- open source alternative to AWS
- self-host my own cloud on bare metal
- cheaper managed PostgreSQL hosting
- reduce GitHub Actions CI costs with managed runners
- provision VMs with firewall and load balancer
- avoid cloud vendor lock-in
- run Kubernetes on bare metal
- host AI inference workloads cheaply

## When to choose
- you want an open, portable cloud alternative to AWS/Azure/GCP with 3-10x lower costs
- you need managed PostgreSQL backed by fast local NVMe storage
- you want cheaper GitHub Actions runners with a one-line workflow change
- you want to build your own cloud on leased bare metal from Hetzner, Leaseweb, or Latitude.sh
- you run compute- or memory-intensive batch workloads like scientific computing or video processing

## When to avoid
- you need the breadth of ~200 services offered by hyperscale clouds (Ubicloud implements only the highest-consumption subset)
- you require replicated block storage or other enterprise-grade durability guarantees out of the box
- your workloads depend on proprietary AWS/Azure/GCP services or deep ecosystem integrations
- you need guaranteed enterprise SLAs and response times without a support contract
