Top 15 trusted cloud migration companies in Europe

The European cloud computing market was estimated at $325.92B in 2025 and is projected to reach $550.42B by 2030 [1]. This number confirms accelerating cloud migration across European organizations. Yet they still face technical complexities during adoption. To address these challenges, most enterprises in Europe (58%) choose partnering with managed service providers (MSPs) to outsource cloud migration [2].

But how can you select a vendor among hundreds of cloud migration companies in Europe? How to find your future partner that can manage complex cloud dependencies and regulatory requirements? To help you choose, we compiled a list of 15 trusted European migration vendors with certified cloud partnerships, compliance credentials, and proven delivery experience.

Our selection criteria

Shortlisting vendors in a large market requires a structured approach. Many IT companies list cloud migration as a service, but the depth of their expertise varies significantly. To separate providers with proven experience, we applied the following criteria:

• More than 250 technical professionals on board. Cloud migration often involves multiple disciplines working in parallel: infrastructure management, DevOps, security, data management, and more. Only medium- and large-sized vendors can bring the comprehensive expertise, offering a range of cloud-related services without the staffing overhead or time delays.
• Over 10 years of experience in the EU market. Long-standing market experience highlights the vendor’s resilience and adaptability amid increasingly complex technical challenges. During this time, an outsourcing vendor can gain deep industry expertise and build a reputation that can be verified through client portfolios.
• 4.7 or higher rank on Clutch with a minimum of 10 verified reviews. Platforms like Clutch conduct verified client interviews rather than accepting self-reported ratings. This makes them a more reliable source of assessing actual delivery quality. The minimum review count ensures the score reflects a consistent pattern across the vendor’s projects.
• Deep expertise, backed by cloud platform partnerships. A trusted consultant should demonstrate expertise across the full cloud migration stack: architecture design, workload assessment, infrastructure provisioning, and post-migration optimization. Official partnerships with hyperscalers, AWS, Azure, and GCP, confirm the vendor’s expertise. Cloud service providers require their partners to pass independent competency assessments and provide access to dedicated support channels and migration tools.
• Delivery experience with EU data sovereignty and compliance frameworks. Organizations operating in Europe or serving EU markets are accountable for how their data is handled in the cloud. GDPR, the NIS2 Directive, and related sovereignty requirements have made compliant cloud delivery in Europe more demanding. A trusted vendor should have experience with EU compliance and cloud sovereignty to help reduce future regulatory risk.
