Tips, Tricks, & Key Information: How to Get Started with the Hybrid Cloud Using STACKIT

A hybrid cloud infrastructure offers many advantages—if it’s properly planned and implemented. With these six practical recommendations, you can unlock the full potential of the STACKIT hybrid cloud while ensuring security, efficiency, and compliance.

Classify Data Correctly

Carefully assess which data requires special protection—such as personal or security-critical information. This data should preferably be processed in the private cloud, while less sensitive applications can be moved to the public cloud.

Migrate in Stages

Start with non-critical applications in the public cloud. This allows you to gain initial experience before migrating more complex systems. Pilot projects help optimize processes and identify risks early on.

Automate management

Use centralized automation tools to efficiently manage hybrid environments. This allows you to maintain a clear overview at all times—even when dealing with compliance requirements or audits.

Define a security strategy

Rely on confidential computing and end-to-end encryption to reliably protect sensitive data, even in distributed infrastructures. STACKIT offers verified, enterprise-level security mechanisms for this purpose.

Seamlessly integrate IT systems

Ensure early on that your existing IT landscape is compatible with the STACKIT platform. A well-planned integration ensures smooth operations and rapid deployment without lengthy transition phases.

Frequently Asked Questions About STACKIT’s Hybrid Cloud

What is the difference between a hybrid cloud and a multi-cloud?

A hybrid cloud combines private and public cloud environments into a consistent infrastructure. Workloads can be flexibly moved between these environments—for example, based on security or performance requirements. In contrast, a multi-cloud strategy uses multiple independent cloud providers in parallel, usually without deep integration of the platforms.

Which workloads benefit most from a hybrid architecture?

Hybrid clouds are ideal for mixed application scenarios: Sensitive data or business-critical applications remain in the private cloud or on-premises, while scalable, volatile, or non-critical workloads—such as web portals, dev/test environments, or big data analytics—are efficiently run in the public cloud.

How are data security and compliance ensured in the hybrid cloud?

Security and compliance are based on multiple layers: encryption (at rest and in transit), fine-grained access controls, network segmentation, and the use of certified data centers. In addition, centralized security policies and monitoring tools ensure consistent implementation and auditability—even in mixed environments.

What are typical challenges in hybrid cloud management?

Operating hybrid environments requires solutions for integrating different platforms, unified monitoring and logging, automated resource management, and the orchestration of workloads across cloud boundaries. It is also crucial that the IT team has the appropriate expertise and governance structures in place.

How can existing systems be successfully migrated to a hybrid cloud?

A proven approach is phased migration: Start with less sensitive applications to establish technical foundations, processes, and governance. At the same time, the private cloud remains in place for systems requiring protection. Modern management and automation tools such as STACKIT Confidential Kubernetes enable a secure and controllable transition—including data flow control, access management, and compliance tracking.
