This report documents a one-time validation. Lobster installed and tested the Lobster Data Platform (LDP) on T Cloud Public. T Cloud Public—formerly the T-Systems Open Telekom Cloud (OTC)—is a public cloud service from T-Systems International GmbH. It is based on OpenStack and hosted in European data centers.
Validation result: Passed
This report covers the Lobster Data Platform 26.3.1 on T Cloud Public in the
eu-deregion.
Executive summary
Lobster validated T Cloud Public as a deployment target for the LDP. The validation used the eu-de region. It passed with no blocking issues.
The standard installation process applied unchanged. T Cloud Public's services met all infrastructure requirements. The setup of the virtual machine (VM) and the managed database was straightforward.
The network configuration in T Cloud Public can differ from other clouds. You can set it up with the official T-Systems OTC documentation. This point did not block the validation.
Scope and objectives
Purpose
This validation confirms that the LDP installs and runs on T Cloud Public infrastructure. It covers a single-node installation. It checks basic installability and core feature functionality.
This report is not a performance benchmark. It is not a security audit. It is not a production readiness assessment.
What was validated
Installation of the LDP on a Linux VM running AlmaLinux 9.
Connectivity between the application and a PostgreSQL database instance.
The execution of a sample end-to-end integration pipeline.
Basic platform stability, including service restart behavior.
What was not validated
High availability (HA) or multi-node deployments.
Performance under load.
Disaster recovery or backup behavior.
Long-term operational stability.
Provider-managed security controls or compliance posture.

Validation period | July to August 2026 |
Infrastructure topology
The Validated Deployment Targets program generally uses a Linux distribution from the RHEL family (RHEL = Red Hat Enterprise Linux). Options include RHEL, Fedora, CentOS, or AlmaLinux. The database is PostgreSQL.
This validation used AlmaLinux 9. See the software version table below.
The table below shows the target instance sizes. The minimum is the lowest acceptable configuration. The recommended size was used where T Cloud Public offered it.
Component | Minimum | Recommended | Used in this validation |
|---|---|---|---|
Application VM: vCPU | 2 | 4 | 4 |
Application VM: RAM | 8 GB | 16 GB | 16 GB |
Application VM: storage | 100 GB SSD | 100 GB SSD | 100 GB SSD |
Database: vCPU | 2 | 4 | 4 |
Database: RAM | 8 GB | 16 GB | 16 GB |
This validation used a general-purpose x1 instance. It provides 4 vCPU and 16 GB of memory.
Software version
Component | Version |
|---|---|
Lobster Data Platform | 26.3.1 |
Java runtime | 21 (Adoptium, |
PostgreSQL | 17.9 |
OS distribution and version | AlmaLinux 9 |
Installation summary
Lobster delivered the installer to the VM with SCP (SCP = Secure Copy Protocol). The installation followed the standard customer process. It used the installer GUI. Java was installed with wget. The download link pointed to Adoptium. The platform used HTTPS on the standard port 443. The application connected to a managed PostgreSQL service on T Cloud Public. The database was reachable only inside a private virtual network (VNET) over its internal DNS endpoint. The PostgreSQL client was installed on the VM to create and manage the database.
Test results
Test execution summary
The installation process produced no errors in the log.
# | Test | Result |
|---|---|---|
T1 | Platform components are all running and healthy | Passed |
T2 | LDP UI is reachable, and login is successful | Passed |
T3 | A sample integration pipeline is executed end-to-end | Passed |
T4 | Data written to and read from PostgreSQL successfully | Passed |
T5 | No blocker-level errors in logs after pipeline execution | Passed |
T6 | Platform restarted cleanly after simulated reboot | Passed |
Issues identified
The validation identified no issues during testing.
Known limitations

The validation identified no limitations beyond those documented in the standard release notes.
Customer relevance
T Cloud Public—formerly the T-Systems Open Telekom Cloud (OTC)—is a public cloud service from T-Systems International GmbH. It provides compute, storage, and network resources in line with strict European data protection standards. The platform is based on OpenStack and runs primarily in secure data centers in Germany and across Europe. The Lobster Data Platform is validated for this environment. Customers can use T Cloud Public infrastructure to install and run the platform. This works like any standard cloud environment.
Revalidation
Lobster recommends revalidation under any of these conditions:
A major Lobster Data Platform release with infrastructure-relevant changes is published.
T Cloud Public changes a core service relevant to this installation, such as network, compute, or database.
12 to 18 months pass from the date of this report, whichever comes first.
