Strengths & weaknesses
Automatically derived from the editorially reviewed rating data and backed by the category ratings (1–10) — fair to both sides.
Strengths
- Maximum operational sovereignty (10/10) combined with a high SEAL Score of 8.2/10 (82%) and SEAL 3 certification.
- Strong data security and encryption (9/10), supported by technical measures such as Confidential Cloud by Edgeless Systems and a Secrets Manager.
- Excellent Linux support (10/10), making STACKIT the optimal target platform for Linux workloads and open-source ecosystems.
- Solid managed database portfolio (8/10) with true DBaaS services such as PostgreSQL Flex, MariaDB, SQLServer Flex, MongoDB Flex, Redis, and OpenSearch.
Points to consider
- No global reach (1/10) with only 2 regions in 2 countries, making the provider unsuitable for workloads outside Europe.
- Weak AI and Big Data offering (3/10 each), with many AI services listed only as 'announced' and Dremio being in beta stage.
- No bare metal offering (1/10), which limits specific hardware requirements as dedicated physical servers are not offered.
Strengths
- Maximum operational sovereignty (10/10) through fully EU-based operations with support and staff, ensuring independence from non-EU interventions.
- High technological sovereignty (9/10) thanks to open standards and low lock-in, significantly above the average of all providers (Ø 7.4).
- Broad service portfolio with over 80 services, offering a comprehensive range of managed databases, Kubernetes, and storage.
- Attractive pricing options for certain workloads, particularly for RAM (8.6/10) and block storage (8.2/10), as well as Saving Plans with up to 48% savings.
Points to consider
- Weak AI and Big Data offering (2/10 each), which is significantly below the average of all providers (AI Ø 4.8; Big Data Ø 4.8).
- Lack of enterprise virtualization paths (1/10), as no managed VMware or Hyper-V migration target is offered.
- Moderate price competitiveness for CPU (4.2/10), GPU (4.5/10), and egress (3.5/10), which can increase costs for these resources compared to other providers.
