Moving infrastructure to the cloud stopped being a purely technical project a while ago. For many European companies, it has become tied to scalability, compliance, operating costs, and honestly, just keeping older systems manageable without exhausting internal teams. Some businesses are rebuilding parts of their platforms from scratch, while others are simply trying to move away from hardware and fragmented legacy environments that have grown difficult to maintain.

The companies covered in this article approach cloud migration from different angles. Some focus heavily on AWS or Azure ecosystems, some lean into DevOps and automation, and others work more broadly across modernization, architecture, and managed cloud operations. What they tend to have in common is a fairly practical mindset. Less talk about “digital disruption,” more attention to infrastructure stability, migration planning, security, and long-term maintainability once the move is actually finished.

1. Oski Solutions

At Oski Solutions, we work with companies in Europe and North America that are trying to move older systems into more flexible cloud environments without interrupting day-to-day operations. A lot of the projects we handle involve business platforms that have grown over time - separate databases, older .NET applications, custom integrations, and infrastructure that becomes harder to maintain every year. In those cases, cloud migration is usually tied to a larger modernization process rather than a simple infrastructure move.

We provide cloud migration services across AWS, Azure, and hybrid environments, depending on how the client’s systems are already structured. Our team works with technologies like .NET, Node.js, React, Kubernetes, Docker, Terraform, and CI/CD pipelines to rebuild or reorganize applications for cloud-based operations. We also handle API integrations with ERP systems, CRMs, payment tools, and third-party services that businesses still rely on after migration. Oski Solutions mainly works with mid-size companies in sectors like e-commerce, logistics, healthcare, manufacturing, and SaaS, where scalability matters, but so does stability.

Key Highlights:

• Works with AWS, Azure, and hybrid cloud environments

• Supports legacy system modernization

• Uses Docker, Kubernetes, Terraform, and CI/CD workflows

• Experience with Umbraco and WordPress ecosystems

Services:

• Cloud migration services

3. Sigma Software

Sigma Software approaches cloud migration as part of a broader infrastructure modernization process rather than a one-time technical transfer. Their team works with public, hybrid, private, and multi-cloud environments, helping companies move workloads while keeping business systems operational during the transition.

Their engineers work with AWS, Azure, and Google Cloud technologies, along with tools like Kubernetes, Terraform, Jenkins, Docker, Grafana, and Prometheus. Sigma Software also spends quite a bit of attention on infrastructure automation and CI/CD processes during migrations, which makes sense because many organizations discover that simply moving servers to the cloud does not automatically improve delivery speed or system reliability.

Conclusion

Cloud migration projects rarely fail because somebody picked the “wrong” cloud provider. More often, the problems come from rushed planning, underestimated dependencies, or trying to modernize everything at once without understanding how older systems actually behave in production. That is probably why many of the companies in this list spend as much time on assessments, architecture reviews, governance, and post-migration support as they do on the migration itself. Moving infrastructure is one thing. Keeping operations stable after the move is usually the harder part.

What also stands out across the European market is how different these providers are from one another. Some companies stay heavily focused on AWS ecosystems, others build around Azure environments, while a few lean more toward analytics, data platforms, DevOps automation, or enterprise modernization. There is no single model that fits every business. A healthcare platform handling sensitive records will naturally approach migration differently from a retail company rebuilding reporting systems or a logistics provider trying to reduce infrastructure overhead during seasonal spikes. That difference matters more than flashy positioning or oversized claims.

For companies planning a migration, the useful question is probably not “who is the biggest provider?” but rather “who actually understands the systems we already have?” In many cases, cloud migration ends up exposing years of technical shortcuts, forgotten integrations, and workflows nobody touched because they still somehow worked. The better migration teams tend to recognize that reality early and work around it instead of pretending every environment is clean and easy to modernize.
