Cloud adoption has matured beyond the initial migration wave. For many enterprises, the next challenge is modernizing the applications, data platforms and operating models that sit on top of their cloud infrastructure.
Moving workloads to the cloud can improve scalability and flexibility, but it does not automatically eliminate technical debt. Organizations often need to redesign applications, modernize databases, improve observability and establish better governance once workloads are operating in the cloud.
PwC’s 2025 EMEA Cloud Business Survey found that 94% of technology leaders planned to adjust or expand their cloud architecture. The survey also found that 86% considered agentic AI important when selecting cloud providers, illustrating how cloud strategy is becoming increasingly connected to AI adoption.
This convergence is changing what enterprises expect from technology partners. Cloud modernization increasingly requires expertise across infrastructure, applications, data, AI, security and cost management rather than a migration project in isolation.
Best cloud modernization partners in Europe
Sonata Software approaches cloud modernization as part of a broader modernization engineering strategy. Its cloud practice combines migration, application modernization, data modernization, AI and FinOps, with the objective of helping enterprises evolve existing technology environments rather than simply relocating them.
The company strengthened its AWS credentials in 2026 by achieving AWS Premier Tier Services Partner status in February and AWS Migration and Modernization Competency status in April. AWS describes the latter as recognition for partners with validated expertise in helping customers migrate and modernize workloads.
Sonata also maintains a long standing Microsoft relationship, giving its cloud modernization practice exposure to both major enterprise cloud ecosystems. Its approach includes cloud migration, application modernization, data platforms and AI enabled engineering, allowing modernization programs to extend beyond the initial infrastructure move.
