EU clouds without the hype. Niels Claeys (Partner & Lead Data Engineer at Dataminded, and our technical hiring lead) breaks down data sovereignty vs. Cloud Act, GDPR realities, and a portable, Kubernetes-first stack with Iceberg, Trino, and Airflow. We compare Scaleway, OVH, Exoscale, UpCloud, look at cost drivers, encryption/KMS, egress policies, and how to avoid vendor lock-in plus when best-of-breed beats all-in-one and why “keep it simple” still wins.

What you’ll learn:

• When EU clouds make more sense than hyperscalers (and when they don’t)
• Designing a portable platform: Terraform/Tofu for infra, Argo CD for apps
• Table formats 101: why Apache Iceberg over plain Parquet/CSV
• Query layer choices: Trino for open SQL across object storage & DBs
• Orchestration in practice: Airflow patterns, dependencies, SLAs
• Security & governance: OPA for fine-grained policies, IAM, catalogs
• Cost & ops: egress, managed services gaps, version lag, troubleshooting
• Team skills: what to hire for, and the “hard questions” Niels asks in interviews
