In which areas do you expect PostgreSQL to grow most and how does your company contribute to and benefit from that growth?
We see the strongest growth for PostgreSQL in sovereign cloud environments. As
the demand for digital independence in Europe rises, PostgreSQL has become the
go-to open-source standard for organizations avoiding proprietary lock-ins. STACKIT
contributes to this by offering a truly European managed service.
Our mission is to reduce dependency on non-European providers and protect data
from external access or exploitation. Recent history has shown that reliance on
foreign infrastructure can even hinder European legal entities. By providing
PostgreSQL within our sovereign cloud, we enable users to leverage a world-class
database while ensuring their data remains under European control. We benefit from
this growth by attracting partners who prioritize security and self-determination.
What is your PostgreSQL centered product and what makes it unique?
STACKIT PostgreSQL Flexuniqueness lies in the perfect balance between enterprise
simplicity and the uncompromising security of the companies of the Schwarz Group
infrastructure.
We offer a "click-and-go" experience that automates deployment, scaling, and
backups, removing the operational burden from developers. Unlike other providers,
we back this simplicity with the stability of one of the largest retail groups in Europe,
hosting everything in our own German and Austrian data centers. This ensures that
high-performance database management remains easy to use while staying fully
compliant and secure within a sovereign European framework.
What makes your company a great place to work?
Working at STACKIT means having a real impact on Europe’s digital future. We
combine a dynamic start-up mentality with the stability of a major corporate group.
Our culture is defined by openness and international collaboration, where diverse
teams work together to solve complex challenges.
What truly sets us apart is our shared purpose: we are building the sovereign
European cloud that our economy urgently needs. Our employees aren't just
managing infrastructure; they are architects of digital independence. This mission,
paired with a flexible and supportive environment, makes STACKIT a place where
innovation and values go hand in hand.
Which PostgreSQL extension do you benefit from most, and why?
We see the most significant impact from pgvector and pgaudit.
pgvector is essential for our customers who are building modern AI applications. It
allows them to store and search vector embeddings directly within their sovereign
PostgreSQL instances, making it the cornerstone for secure, RAG-based
(Retrieval-Augmented Generation) AI solutions in Europe.
On the other hand, pgaudit is vital for our mission of digital sovereignty and security.
Since we serve highly regulated industries and public sectors, the detailed logging
provided by pgaudit ensures the transparency and compliance our customers
require. It allows them to fulfill strict auditing requirements while benefiting from the
flexibility of a managed open-source database.
What feature is missing in PostgreSQL and how would it help if added?
The most significant missing feature in PostgreSQL core is Transparent Data
Encryption (TDE). While there are workarounds at the filesystem or disk level, native
TDE within the database engine would provide a much more granular and robust
security layer.
As a provider focused on digital sovereignty and high-security standards, having
TDE natively integrated would greatly simplify compliance for our customers in
regulated industries. It would allow for encryption at rest that is independent of the
underlying storage architecture, providing an extra layer of protection against
unauthorized data access. Adding this would bring PostgreSQL on par with other
enterprise database systems while maintaining its open-source integrity, making it
even more attractive for sensitive European workloads.
