GCP → OVHcloud

Migrating from GCP to OVHcloud

OVHcloud is Europe's largest cloud provider (French, HQ Roubaix) and carries the broadest managed catalogue among EU providers. GKE, Cloud Storage and Cloud SQL have close OVHcloud equivalents; BigQuery and Spanner do not.

Which GCP services have a true OVHcloud equivalent?

Graded conservatively. OVHcloud's managed Kafka is a genuine edge over most EU providers.

Where do the GCP APIs diverge?

The commodity layer repoints cleanly. These services have no managed OVHcloud twin.

  • BigQuery: retarget to ClickHouse.
  • Cloud Spanner: no managed equivalent.
  • Vertex AI: assembled from OVHcloud AI Notebooks and AI Deploy.

Which of your services move cleanly?

10 capabilities

  • Object storage

    Hyperscaler Amazon S3 Azure Blob Storage Google Cloud Storage
    EU-sovereign path Scaleway Object StorageOVHcloud Object Storage
    Verdict Mature

    S3-compatible API. A drop-in target for most SDKs, backups and static assets.

  • Block storage

    Hyperscaler Amazon EBS Azure Managed Disks Persistent Disk / Hyperdisk
    EU-sovereign path Scaleway Block StorageOVHcloud Block Storage
    Verdict Mature

    Network block volumes with snapshots. Standard building block, well covered.

  • Virtual machines

    Hyperscaler Amazon EC2 Azure Virtual Machines Google Compute Engine
    EU-sovereign path Scaleway InstancesOVHcloud Public CloudHetzner Cloud
    Verdict Mature

    General-purpose and dedicated instances are a solved problem in the EU.

  • Managed Kubernetes

    Hyperscaler Amazon EKS Azure AKS Google Kubernetes Engine (GKE)
    EU-sovereign path Scaleway KapsuleOVHcloud Managed Kubernetes
    Verdict Mature

    CNCF-conformant managed control planes. Portable workloads move with little friction.

  • Container registry

    Hyperscaler Amazon ECR Azure Container Registry Google Artifact Registry
    EU-sovereign path Scaleway Container RegistryOVHcloud Managed Private RegistryHarbor (self-hosted)
    Verdict Mature

    OCI registries are commodity. Self-hosted Harbor is a fully sovereign fallback.

  • Managed PostgreSQL

    Hyperscaler Amazon RDS / Aurora Azure Database for PostgreSQL Cloud SQL / AlloyDB for PostgreSQL
    EU-sovereign path Scaleway Managed DatabaseOVHcloud Managed DatabasesAiven for PostgreSQL
    Verdict Viable

    Standard PostgreSQL is well served. Aurora-specific features (e.g. global database, serverless v2 autoscaling) have no exact twin, so plan around them.

  • Authoritative DNS

    Hyperscaler Amazon Route 53 Azure DNS Google Cloud DNS
    EU-sovereign path Scaleway Domains & DNSOVHcloud DNSBunny DNS
    Verdict Viable

    Managed authoritative DNS is well covered. Route 53's routing policies need a manual rebuild.

  • Serverless functions (FaaS)

    Hyperscaler AWS Lambda Azure Functions Cloud Run functions (Cloud Functions)
    EU-sovereign path Scaleway Serverless FunctionsOVHcloud Functions
    Verdict Partial

    The runtimes exist, but Lambda's breadth of native event sources and mature cold-start tuning is not matched. Fine for HTTP and cron; harder for deep event-driven fan-out.

  • Global CDN & edge compute

    Hyperscaler Amazon CloudFront / Lambda@Edge Azure Front Door Cloud CDN / Media CDN
    EU-sovereign path Bunny.netGcoreOVHcloud CDN
    Verdict Partial

    EU-headquartered CDNs deliver content well globally. Edge-compute primitives (equiv. to Lambda@Edge/CloudFront Functions) are thinner and less mature.

  • Managed ML platform

    Hyperscaler Amazon SageMaker Azure Machine Learning Vertex AI
    EU-sovereign path OVHcloud AI Endpoints / AI TrainingScaleway GPU Instances + Managed Inference
    Verdict Gap

    GPU compute, training and inference endpoints exist, but nothing matches SageMaker's end-to-end breadth (pipelines, feature store, model registry, tuning) as one managed platform. You assemble it.

Verdicts are conservative and reflect managed, EU-jurisdiction offerings as of 2026. Provider feature sets move quickly, so we re-check on every engagement.

How many engineer-days?

40-100 engineer-days

A directional range. The spread depends on BigQuery and Spanner dependencies.

  • Mid-sized estate: GKE, Cloud Storage, Cloud SQL, possibly BigQuery.
  • Low: GKE/GCS/Cloud SQL that repoint by configuration.
  • High: BigQuery rebuild; Spanner re-architecture.

Where does OVHcloud run?

Multiple EU data centres with EU data-sovereignty guarantees.

  • Gravelines (GRA), FranceFlagship French region.
  • Strasbourg (SBG), FranceRebuilt after 2021 fire.
  • Frankfurt (DE)German data-residency option.
  • Warsaw (WAW), PolandCentral-European footprint.

Honest limitations

  • BigQuery and Spanner have no twin Plan them first.
  • 2021 Strasbourg fire Design cross-region DR.
