STACKIT operates under strict GDPR compliance and focuses on data sovereignty, ensuring that your data remains fully within the European Union. Visit the official site here.

What is STACKIT?

STACKIT is the cloud platform of the Schwarz Group, part of its IT and digital division Schwarz Digits, headquartered in Neckarsulm, Germany. Originally developed for internal use by retail brands such as Lidl and Kaufland, it has been extended since 2022 to external customers in business, public administration, and regulated sectors. It aims to serve as a sovereign European cloud alternative to US-based hyperscalers including AWS, Azure, and Google Cloud.

Core Offerings and Structure

• Services: STACKIT offers a full stack of cloud and hosting services—object storage, block storage, Kubernetes, virtual machines, managed databases (PostgreSQL, MySQL), messaging (e.g. RabbitMQ), logging & monitoring (ELK stack), Redis, MongoDB, networking and security tools.
• Data Centers & Regions: All STACKIT data centers (Germany and Austria) are operated by STACKIT themselves. Regions EU01 (Germany) and EU02 (Austria) are exclusively used. Each region comprises multiple availability zones with redundancy and high availability (99.98%).
• Certifications & Standards: STACKIT infrastructure meets strict standards such as ISO 27001, BSI’s C5 (Type 2), ISAE 3000, ISAE 3402. These certifications cover compliance, cybersecurity, and information security.

Data Sovereignty, GDPR & Legal Security

STACKIT’s selling point is its commitment to GDPR and European legal jurisdiction. All data storage, processing, and development occur on servers located in Germany and Austria. Because StackIT is a European entity with no legal ties that oblige it to submit to non-EU laws like the US CLOUD Act, it avoids many of the legal risks that apply to US-based cloud providers.

This makes STACKIT particularly appealing for sectors with sensitive or regulated data—healthcare, public administration, critical infrastructure—since compliance with GDPR, digital sovereignty, and transparency are fully satisfied.

Sustainability & Green Energy

STACKIT does operate with 100% green electricity at all its data centers in Germany and Austria. A showcase is the DC10 data center in Ostermiething, Austria, which features extremely efficient cooling systems (river water cooling, hot water cooling), waste heat recovery, a PUE value around 1.1, and gold certification from the Austrian Sustainable Building Council (ÖGNI).

Plans, Pricing & Free Tier

• Free Plan: STACKIT does not offer a free plan. Services are based on pay-as-you-go and usage-based fees.
• Pricing: While no fixed public price list is displayed under “plans and pricing,” the cost model is transparent. Users can estimate costs via a calculator provided by STACKIT. Customers pay for resources used: compute, storage, data transfer, etc.—no bundled commitments are required.

Strengths Compared to Big Tech Providers

1. True European cloud control: Unlike AWS, Azure or Google Cloud, StackIT operates entirely within the EU, governed by EU law. That means, for example, AWS Cloud regions hosted in Frankfurt or Milan still have parent companies under US laws and may, in theory, be subject to US government demands. STACKIT avoids that risk.
2. Data protection: Full GDPR compliance, with all data processing, backups, and operations within EU jurisdiction. This gives stronger guarantees than many global providers can offer, especially when sensitive personal or business data is involved.
3. Sustainability leadership: Green energy usage, efficient cooling technologies, and environmental certifications place STACKIT among providers with strong environmental credentials. Many global providers do make similar claims—but often with data centers across multiple jurisdictions, which complicates transparency.
4. No vendor lock-in: STACKIT stresses compatibility (e.g., S3-compatible object storage, Kubernetes support), enabling easier migration. By contrast, tools built deeply into proprietary ecosystems (e.g. AWS‐specific APIs) tend to lock users in.

Considerations & Limitations

• Open-source status: STACKIT is not fully open source. While it builds on open standards in many respects, some services and proprietary control remain within its own stack.
• Free usage / entry cost: Absence of a free tier may make it harder for small developers or hobbyists to experiment before committing. Global competitors often offer free tiers as incentive. STACKIT instead emphasizes transparent pricing and pay-as-you-go.
• Service maturity & global reach: As a newer entrant beyond the Schwarz Group’s internal needs, support, service maturity and availability in some regions may lag behind AWS, Azure, and Google, particularly outside Germany/Austria. Some services are available only in certain regions.

Use Cases & Who Should Use STACKIT?

• Sensitive data regimes: Government entities, healthcare providers, financial institutions or critical infrastructure operators who require GDPR compliance, local processing, and sovereign control.
• European-based businesses: Companies headquartered in Europe that want their cloud infrastructure close by and legally under EU jurisdiction to reduce latency, compliance risk, and vendor‐law risks.
• Retail & logistic brands: Given its origins with Lidl and Kaufland under the Schwarz Group, STACKIT is well-suited for large retail operations seeking robust infrastructure, especially during peak events (e.g. Black Friday) where scalability matters.
• Organizations with sustainability goals: Entities aiming to meet environmental reporting obligations will benefit from STACKIT’s green energy usage, waste heat recovery, and energy-efficient data centers.

Summary

STACKIT provides a compelling European cloud and hosting alternative built for organizations that prioritize data protection, sovereignty, compliance with GDPR, and sustainable operations. By avoiding the legal ambiguities that often surround non-EU cloud providers, STACKIT positions itself as a trusted platform for companies needing strong guarantees over where and how their data is handled. While it lacks a free tier and may not yet have the same global scale as US hyperclouds, its strengths lie in delivering transparent, secure, EU-based infrastructure with modern services tailored for the era of digital regulation.
