GCP → STACKIT

Migrating from GCP to STACKIT

STACKIT is the cloud arm of the Schwarz Group (Lidl/Kaufland), German-operated with two EU regions. GKE and Cloud SQL have managed equivalents; BigQuery and Spanner do not.

Which GCP services have a STACKIT equivalent?

STACKIT offers managed Kubernetes and PostgreSQL; analytics are self-hosted.

Where do the GCP APIs diverge?

BigQuery and Spanner have no managed STACKIT twin.

  • BigQuery: ClickHouse self-hosted.
  • Cloud Spanner: no managed twin.

Which services move cleanly?

Scoped to STACKIT managed services.

7 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.

  • 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.

  • Managed cache (Redis/Valkey)

    Hyperscaler Amazon ElastiCache Azure Cache for Redis Memorystore for Redis
    EU-sovereign path Scaleway Managed Database for RedisAiven for Valkey/Redis
    Verdict Viable

    In-memory caching is well covered; Valkey is the emerging open successor to Redis.

  • Secrets & key management

    Hyperscaler AWS Secrets Manager / KMS Azure Key Vault Secret Manager / Cloud KMS
    EU-sovereign path Scaleway Secret ManagerHashiCorp Vault (self-hosted)
    Verdict Viable

    Managed secret storage exists; self-hosted Vault gives full control including HSM-backed keys.

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

Similar to other managed EU targets.

  • Low: GKE, Cloud Storage, Cloud SQL.
  • High: BigQuery rebuild.

Where does STACKIT run?

Two German regions; EU data-sovereignty.

  • Heilbronn, Germany (eu01)Near Schwarz HQ.
  • Austria (eu02)Second EU region.

Honest limitations

  • BigQuery and Spanner have no twin Plan them first.
  • Young platform Narrower catalogue than OVHcloud.

CTO questions

Do GKE and Cloud SQL repoint?
Yes.
Is STACKIT sovereign for German mandates?
Among the strongest.
