Open sourceA practical guide to reducing lock-in risk when you choose OVHcloud Public Cloud and OpenStack instead of a deeper AWS-style stack.
OpenStack can make OVHcloud meaningfully more portable than AWS, but it does not magically remove vendor lock-in. The biggest difference comes from how you architect on top of the cloud, not just from the cloud brand itself.
OVHcloud Public Cloud explicitly positions itself around open standards such as OpenStack, and that really does help. At the infrastructure layer, you are closer to portable building blocks like compute instances, block storage, images, and networking primitives instead of being pushed immediately into a long list of proprietary platform services.
That usually means your migration path is better than it would be on an AWS-first design full of provider-native services. But OpenStack reduces lock-in; it does not erase it. Providers still differ in quotas, networking behavior, APIs around the edges, managed services, operational defaults, and support workflows.
If portability matters, treat OVHcloud mainly as infrastructure. Use virtual machines, attach storage explicitly, keep your own images, and keep your network design simple enough that it can be rebuilt somewhere else without weeks of translation work.
A good rule is to ask whether a future migration would mostly be a rebuild of infrastructure or a rewrite of architecture. If it is the second one, you are already drifting into lock-in.
The easiest way to create accidental lock-in is to build everything by hand in a cloud control panel. Use infrastructure as code so your real system is described outside the provider UI.
OpenTofu or Terraform-style workflows make it much easier to rebuild the same infrastructure somewhere else, compare providers, and see exactly what assumptions your platform makes.
Kubernetes can be a useful portability layer because your application deployment model becomes less tied to one vendors VM layout or platform conventions. But Kubernetes only helps if you avoid filling the cluster with provider-specific add-ons that are hard to replace.
A portable Kubernetes setup still needs portable storage assumptions, portable ingress patterns, portable observability, and a realistic backup and restore story.
In practice, the hardest things to move are usually not raw VMs. They are data, identity, surrounding automation, and assumptions buried in your ops habits.
If you want OVHcloud to stay portable, keep a close eye on the parts of the stack that quietly become unique to one provider over time.
A practical portability-first OVHcloud stack often looks like this: OpenTofu for infrastructure, simple compute instances, a small number of predictable networks, containers or Kubernetes for app deployment, PostgreSQL or MySQL kept in a migration-friendly setup, and backups tested somewhere outside OVHcloud.
That kind of stack is not lock-in free, but it is realistic to move. That is usually the right target.
