Databases have to respond, servers have to run, deployments have to be traceable. The technology underneath has changed several times in three decades: from Solaris and HP-UX to Red Hat Enterprise Linux, from Oracle 7 to 19c, from manual installs to OpenShift, Kubernetes and PostgreSQL. We have seen each of these transitions through in live operations, and that experience goes into your project.
OpenShift and Kubernetes, Kafka, Ansible and AWX, GitLab, Helm and Flux. We build the platform, run it and automate whatever repeats.
Typical for: Platform and DevOps teams building, stabilizing or rolling out OpenShift/Kubernetes and Kafka to further environments
Oracle 7 to 19c with RAC, Data Guard and APEX, PostgreSQL with Patroni, MariaDB Galera, Exasol, MS SQL Server. Setup, upgrade, tuning, migration, operations.
Typical for: Database teams facing an upgrade, a performance problem or a migration; data warehouse operators on Oracle and Exasol
Red Hat Enterprise Linux 3 to 10, SLES, Debian as well as Solaris, HP-UX and AIX. Patch management, platform migrations, performance tuning, high availability, application servers.
Typical for: Operations departments with mixed RHEL, Solaris, HP-UX and AIX estates
AWS, VMware vSphere, Nutanix, Terraform. We evaluate, build prototypes and migrate, with an eye on the legacy systems that have to come along.
Typical for: Teams deciding between cloud and their own data center, or facing a VMware upgrade or platform migration
checkmk, Nagios, Grafana, Oracle Enterprise Manager; backup and recovery with RMAN; failover clusters, Patroni, Galera, HAProxy and Keepalived. We spot incidents early and build systems that survive them.

Project and sub-project management for upgrades, data center moves and outsourcing transitions. Estimates, SLA negotiation, high-availability and backup concepts. Training within the project included.

IB is short for Ingenieurbüro, the German word for engineering office: Gregor Theis founded Ingenieurbüro Theis in Düsseldorf in 1992, the office moved to Meerbusch in 2005 and has traded as IB Theis GmbH since 2025. Most of our clients are in the greater Düsseldorf area: banks and telecommunications companies where we have been regulars for years. On site in under an hour, remote at once, and for short assignments we also work worldwide.
