When does T Cloud Public make sense?

T Cloud Public (previosly known as Open Telekom Cloud) shows its strengths when workloads and projects need to run in a European cloud environment—especially when data location, compliance, or sovereignty play a key role. Before making a decision, we assess whether the available services, performance, and operating model fit your specific use case.

How does SUNZINET support T Cloud Public projects?

SUNZINET supports T Cloud Public projects across applications, infrastructure, and ongoing operations. We translate requirements into architectural decisions and ensure that services, security, and operational processes work together seamlessly.

Which services are most relevant for projects?

Typical T Cloud Public architectures combine compute, networking, storage, databases, containers, key management, and monitoring. The right combination of services depends on the workload, required integrations, and the desired operating model.

How does T Cloud Public differ from Azure?

T Cloud Public (previosly known as Open Telekom Cloud) is particularly relevant when European data locations, sovereignty, and an OpenStack-based architecture are key requirements. Azure, on the other hand, offers a broader global service ecosystem and deep integration within Microsoft environments.

How We Deliver Your Open Telekom Cloud Project

Data Location & Service Fit

We assess requirements, data protection, performance, integrations, risks, and the long-term operational effort.

Building the Target Architecture

We define VPC, IAM, security groups, service boundaries, and backup requirements.

Automating the Platform

We implement Infrastructure as Code, CI/CD, GitOps, and standards for reproducible environments using ECS, CCE, OBS, and RDS.

The “C” in MACH

Not every project needs complexity. But every project needs an architecture that can scale when it matters. We focus on modular services, clearly defined interfaces, and infrastructure and deployment processes that are built for automation and reproducibility.

This allows teams to roll out new features faster, handle peak loads, and use cloud resources more efficiently.
