Pricing by workload — practical examples
Pricing comparisons require workload definitions. The following examples use standard 2026 pricing models; the final cost depends on committed use, reserved options and discount programs.
Example 1 — Small web app (single node + 50 GB storage)
- Assumptions: 2 vCPU, 4 GB RAM, 50 GB SSD, 2 TB monthly egress
- DigitalOcean: Standard droplet (2 vCPU/4 GB) + 50 GB block storage + 2 TB egress tier → baseline low monthly price with strong predictability. See pricing: DigitalOcean pricing.
- STACKIT: Comparable instance + regional block storage + EU-focused egress pricing → often slightly higher list price but potentially lower regulatory risk and better peering for EU traffic.
Example 2 — Managed Kubernetes cluster (3 nodes, production)
- Assumptions: 3 x 4 vCPU / 8 GB nodes, 1 TB total block storage, load balancer, backup
- DigitalOcean: Managed Kubernetes with node pools priced per Droplet hour. Known for simple cost predictability.
- STACKIT: Managed K8s with enterprise features and EU control-plane; potential higher hourly costs but stronger compliance SLAs and networking features.
Actionable method: Use provider pricing pages and compute Total Cost of Ownership (TCO) for 12 months including egress, snapshots and support. For accurate quotes, consult: DigitalOcean pricing and STACKIT.
Migration checklist and reproducible steps
Pre-migration assessment
- Inventory Droplets, Volumes, Floating IPs, DNS zones and snapshots.
- Map data residency and backups. Create a GDPR checklist referencing the regulation at EU GDPR text.
- Run a performance baseline (CPU, I/O, network p95) on DigitalOcean to compare to STACKIT targets.
Step-by-step migration outline (H3)
- Backup and snapshot: Export images via snapshot; export databases as logical dumps.
- Infrastructure as code: Translate Droplets and networking to Terraform. Reference Terraform: Terraform.
- Provision STACKIT resources: Match vCPU/RAM and volumes; apply security groups and private networking.
- Data transfer: Use rsync over VPN or object storage cross-replication; for large volumes consider offline transfer or expedited network egress.
- DNS cutover: Use short TTLs for an incremental cutover and monitor p95 latencies.
- Short example (pseudo-syntax to adapt to providers):
resource "stackit_instance" "app" {
name = "app-node-1"
cpu = 2
ram = 4096
image = "ubuntu-22.04"
}
Note: Replace provider resource names with official provider Terraform providers and do not copy blindly. Refer to provider docs for exact provider blocks.
Benchmarks and methodology (reproducible)
Benchmark goals and metrics
- CPU single-threaded and multi-threaded throughput
- Disk I/O (IOPS, sequential throughput, fsync latency)
- Network p95/p99 latency and jitter between London and Frankfurt
- Application-level end-to-end latency (HTTP p95/p99)
Reproducible methodology
- Use identical OS images (Ubuntu 22.04), disable burst modes and pin CPU governors.
- Benchmark tools: sysbench for CPU/IO, iperf3 for network, wrk for HTTP. Link to CNCF and tool docs: CNCF.
- Run 3x tests at off-peak and peak times, record medians and p95, p99.
Expected outcomes (2026 observations)
- CPU: Comparable across similar SKUs; slight variations depend on CPU generation.
- I/O: Enterprise block options on STACKIT can provide higher sustained IOPS for database workloads; DigitalOcean block storage is performant for general use but may have AZ constraints.
- Network: For intra-EU traffic, STACKIT can show lower variance due to direct carrier peering in major European IXPs.
Recommendation: Publish raw benchmark scripts in a public repository and repeat tests in target regions before finalising an architectural decision.

FAQ
What is the fastest way to migrate volumes from DigitalOcean to STACKIT?
Create snapshots, export database dumps, provision matching volumes on STACKIT, and transfer data via rsync over a secure connection or using object storage replication. For large datasets, consider staged migration with DNS cutover and temporary dual-write.
Are both providers compliant with EU GDPR?
Both can be configured to meet GDPR obligations. STACKIT typically advertises EU-only hosting and certifications; DigitalOcean supplies DPA options and EU regions. Confirm contractual DPAs and certifications with each provider: refer to EU GDPR.
Which provider offers lower latency in England to other EU regions?
Latency depends on the region chosen and peering. For London↔Frankfurt, providers with local peering tend to show lower variance. Empirical testing with iperf3 or HTTP p95 is recommended before final selection.
Is managed Kubernetes easier to migrate between the two?
Yes; both support standard Kubernetes APIs. Export manifests and use Velero or cluster API tools for PV migration. Ensure CSI driver compatibility for persistent volumes.
How to compare total cost of ownership (TCO) between STACKIT and DigitalOcean?
Compute 12-month operating costs: instances, storage, egress, backups, support, and expected operational overhead for compliance. Include potential savings from EU-compliant features that reduce legal overhead.
Conclusion
Choosing between STACKIT vs DigitalOcean depends on a clear prioritisation of EU data sovereignty, enterprise networking and compliance versus developer ergonomics, ecosystem and predictable low-cost droplets. For regulated EU workloads and lower regulatory risk, STACKIT often offers advantages. For fast-growing startups, test environments and high community support, DigitalOcean remains compelling. A hybrid model is a practical compromise: sensitive workloads on STACKIT and developer/CI workloads on DigitalOcean. Implement reproducible benchmarks and a clear migration plan before committing to a single provider.
