Summary: Mastering Cloud Transformation with Confidence

Cloud transformation is the crucial step toward making legacy IT landscapes future-proof. However, security and compliance must not fall by the wayside, especially when it comes to critical workloads and sensitive data.

With STACKIT, you can migrate and modernize your IT step-by-step and securely to a 100% European cloud infrastructure.

On this page, you’ll learn in a nutshell:

  • How to successfully execute a cloud transformation from initial assessment to secure operation (no “big bang,” but rather a step-by-step migration).
  • What benefits scalability and cloud-native architectures offer for your business growth.
  • Why industries with strict regulations (public sector, digital health, finance) trust STACKIT’s absolute data sovereignty.
  • Practical best practices for implementing your transformation strategically and measurably.

When IT shifts from a project to a process

For years, enterprise IT landscapes have been growing faster than they can be restructured: applications are spread across different servers, data is stored in silos, and digital services must be available online faster and faster—all while meeting high demands for security, legal compliance, and scalability.

Cloud transformation refers to the structured approach of gradually transitioning this IT world into a modern cloud infrastructure—with the clear goal of better aligning IT and business. With STACKIT, companies gain a sovereign cloud platform, operated in data centers in Germany and Austria, that brings modern technologies, digitalization, security, and scalability under one roof.

A cloud transformation is not an end in itself, but is intended to make your IT more stable, flexible, and efficient, thereby measurably supporting your digitalization. STACKIT combines modern cloud technologies with a European-based operational model and provides suitable solutions for various use cases.

Dedicated infrastructure for sensitive data

STACKIT operates its cloud infrastructures in its own European data centers, enabling businesses and public institutions to run applications and store data in compliance with the GDPR. For industries such as digital health, government, and finance, this data sovereignty is a central component of any cloud strategy and one of the key benefits of cloud transformation with STACKIT.

Gradual migration instead of a big bang

With STACKIT, you can replace your existing IT environment in a controlled manner. Workloads are migrated selectively, tested cloud services are integrated gradually, and environments are operated in parallel until requirements, performance, and security are demonstrably met. This ensures your business remains fully operational throughout the process.

Scalability for growing demands

Cloud computing with STACKIT allows you to scale computing power, storage, or platform services as needed—for example, during seasonal spikes in e-commerce traffic, rising user numbers on digital government portals, or new digital health applications. Your IT infrastructure grows with your business, not the other way around.

A stable platform for modern applications

The STACKIT platform offers a range of cloud services, database solutions, and middleware and security components that help companies develop and operate modern digital applications. This enables the integration of existing systems and the rapid deployment of new services—from citizen portals to enterprise software.

Partnership-based support throughout the entire process

Cloud transformation requires a clear strategy, a scalable architecture, a robust security framework, and ongoing management. STACKIT acts as a partner on equal footing, providing consulting, technical best practices, and services tailored specifically to the needs of enterprises, the public sector, and software providers.

Cloud Transformation with STACKIT: How It Works in Detail

Cloud transformation is not a single measure, but a structured process that encompasses strategy, technology, organization, and security. STACKIT supports companies throughout this entire journey—from the initial assessment to an optimized cloud environment.

Every cloud transformation begins with a clear understanding of the existing IT infrastructure: Which applications are business-critical, which data is particularly sensitive, and which systems are holding back innovation? During this phase, legacy systems, hardware, and dependencies are identified and evaluated against the company’s digital goals. This results in a cloud strategy that sets priorities and determines which parts of the IT landscape will be migrated to the cloud and in what order.

Based on this, we define exactly how applications, databases, and systems will be migrated to the STACKIT Cloud. Proven applications are often migrated to the STACKIT infrastructure using a "lift-and-shift" approach to quickly benefit from a stable, scalable environment and centralized management. Systems in need of modernization are gradually made cloud-ready, for example with suitable database services, container platforms, or middleware solutions, while new digital services are built directly as cloud-native on the STACKIT platform and leverage scalability and flexibility from the start.

Once the first workloads are running in the cloud, the focus shifts to secure, compliant operations. For enterprise environments and the public sector, a well-thought-out security strategy is essential: encryption, access rights, monitoring, and logging ensure compliance with legal requirements and industry-specific standards. Through central dashboards, administrators can monitor resources, costs, and performance, adjust capacities as needed, and refine security policies—ensuring that the cloud environment remains stable, auditable, and manageable in the long term.

Digital Government – Modernizing Specialized Systems Without Disrupting Operations

In many government agencies, specialized processes for resident registration, records management, or geodata have been running smoothly for years, but on rigid infrastructure. This is precisely where cloud transformation with STACKIT comes in, connecting proven applications with a scalable, secure environment in the cloud. Step by step, selected processes are migrated, tested in parallel, and linked via interfaces to remaining on-premises systems, ensuring that citizen services are available faster and more reliably.

Practical tips for getting started with cloud transformation using STACKIT

Cloud transformation is more successful when approached as an ongoing process of change rather than a one-time IT project. The following tips highlight what matters most when getting started.

  • Define your target range and priorities: Start by having a clear picture of what the transformation should achieve for your company—such as faster delivery of digital services, higher availability, reducing the workload on internal teams, or better utilization of existing data. Applications with high technical value, strict security requirements, and measurable economic impact should move to the top of the roadmap.
  • Plan the migration step by step: Instead of moving the entire IT infrastructure all at once, it’s worth breaking it down into manageable clusters based on business units, applications, or data landscapes. A separate migration path is created for each group, taking into account dependencies on third-party applications and existing hardware—this keeps operations stable while the environment moves toward the cloud piece by piece.
  • Embed safety and compliance early on: Regulatory requirements such as the GDPR or industry-specific regulations should be an integral part of planning from the start, not just a final check. By consistently factoring in security functions like encryption, access control, and monitoring,you create a cloud environment that passes audits and protects sensitive data in the long term.
  • Make consistent use of automation: Whether it’s new instances, test environments, or resource scaling, many recurring tasks can be automated. When scripts, templates, and integrated tools handle routine work, IT teams gain time for architectural considerations, quality control, and the further development of digital services.
  • Establish transparent cost and resource management: With structured monitoring of utilization, resource consumption, and budget, the cost development of the cloud environment remains traceable at all times. By regularly checking which applications are using which capacities,you can make targeted adjustments, free up reserves, and optimize operations economically.
