Strengths & weaknesses
Automatically derived from the editorially reviewed rating data and backed by the category ratings (1–10) — fair to both sides.
Strengths
- Excellent Linux support with the highest score in the comparison field (10/10, avg: 8.8), ideal for open-source ecosystems.
- Extensive managed database portfolio (8/10, avg: 6.9) with true DBaaS services such as PostgreSQL Flex, MariaDB, and MongoDB Flex.
- Strong encryption infrastructure (Encryption 8/10, avg: 6.8) including KMS, HSM, and Secrets Manager, as well as Confidential Cloud by Edgeless Systems.
- Free egress costs (10/10) and competitive prices for Kubernetes Premium (8.7/10) and RAM (7.7/10).
Points to consider
- Limited strategic options (5/10, avg: 6.2) and weak AI/big data offering (3/10 each, avg: 4.8), with many AI services only 'announced'.
- No global reach (1/10, avg: 4.5) with only 2 regions in 2 countries, unsuitable for international workloads.
- No bare metal offering (1/10, avg: 5.2) and no collaboration tools (1/10, avg: 3.7).
Strengths
- Attractive overall price rating (6.7/10, avg: 6.4) with specific advantages for block storage (9/10) and a 54% Saving Plan.
- High local availability with 5 Availability Zones in Germany and 50+ Points of Presence, supported by a dedicated backbone.
- Open OpenStack stack without lock-in, supported by Managed Kubernetes (MetaKube) and a Terraform provider (announced).
- Maximum operational sovereignty (10/10) and technological sovereignty (9/10) with a focus on German jurisdiction and compliance (BSI C5, ISO 27001).
Points to consider
- Very thin strategic portfolio (4/10, avg: 6.2) with practically no AI or analytics services (AI 1/10, Big Data 1/10, avg: 4.8).
- Low encryption product depth (3/10, avg: 6.8) without a full-featured KMS/HSM, only Barbican Secrets available.
- Narrow managed database offering (4/10, avg: 6.9), predominantly managed VMs rather than true DBaaS; NoSQL only 'announced'.
Which provider when?
Use-case-based decision aid — both options are a valid choice.
Choose STACKIT if:
- You require a broad portfolio of managed databases (PostgreSQL, MongoDB, Redis) with high automation.
- Your workloads are heavily based on Linux and open-source technologies with the highest requirements for encryption and key management.
- You prefer a platform with free egress costs and an established Kubernetes service (SKE).
- You require compliance certifications such as ISO 20000 and ISO 50001 in addition to BSI C5.
Choose SysEleven if:
- You prioritize low total costs (Cost Rating 6.7/10) and intensively use block storage (9/10) and Saving Plans (54%).
- You require a high number of Availability Zones (5) within Germany for maximum local redundancy.
- You prefer an open OpenStack stack with custom operating environments rather than standardized PaaS services.
- You have no requirements for AI, big data, or Microsoft workloads and focus on pure infrastructure.

Frequently asked questions: STACKIT vs SysEleven
What is the difference between STACKIT and SysEleven?
STACKIT offers a broader managed service portfolio, particularly for databases (8/10 vs. 4/10) and encryption (8/10 vs. 3/10), and is more optimized for Linux workloads (10/10). SysEleven focuses on an open OpenStack stack with lower overall costs (6.7/10 vs. 5.4/10) and offers more local Availability Zones (5 vs. 3) in Germany, but largely lacks AI and big data services.
Which provider is more sovereign?
Both providers achieve maximum operational sovereignty (10/10) and high technological sovereignty (9/10). STACKIT has a slightly higher SEAL Score of 8.2/10 (82%) compared to 8.0/10 (80%) for SysEleven. Both are highly sovereign as EU providers with BSI C5 certification and German jurisdiction, with STACKIT covering additional technical sovereignty aspects through Confidential Cloud by Edgeless Systems.
Who is cheaper?
SysEleven has a higher overall price rating (6.7/10) than STACKIT (5.4/10). SysEleven scores particularly well for block storage (9/10) and offers a 54% Saving Plan. However, STACKIT offers free egress costs (10/10) and competitive prices for Kubernetes Premium (8.7/10). Actual costs are highly workload-dependent.
Which provider offers better databases?
STACKIT offers a significantly broader managed database portfolio (8/10) with true DBaaS services such as PostgreSQL Flex, MariaDB, SQLServer Flex, MongoDB Flex, and Redis. SysEleven scores 4/10 here, as predominantly managed VMs are offered and true DBaaS is only available for PostgreSQL; NoSQL is only 'announced' at SysEleven.
Are there AI and big data services?
STACKIT offers limited AI and big data services (3/10 each), including AI Model Serving (ready) and Dremio (Beta), with many other AI services only 'announced'. SysEleven has practically no AI or analytics services (1/10 each) and is not suitable for data-driven or GenAI workloads.
