Migrating to the cloud successfully starts with a granular evaluation of applications, workloads, and their dependencies. This early analysis identifies appropriate cloud models and helps prioritise migration targets. The typical enterprise migration spans about 8 months and averages £1.2 million in costs, yet organisations can see 20–30% savings versus on-premises operations. Moreover, 36% of businesses now include the carbon impact of cloud resources in their decision-making, highlighting the growing focus on green cloud migration.
Selecting the Appropriate Cloud Deployment Model
With cloud usage expanding rapidly, IT leaders must weigh the benefits of public, private, and hybrid environments against their business requirements. Although 96% of organisations use public cloud services, 84% maintain private clouds for sensitive or legacy systems. Multi-cloud approaches, adopted by 89% of enterprises, help prevent vendor lock-in, improve fault tolerance, and satisfy compliance obligations.

Technology, Tools & Partner Selection
Choosing the right cloud providers, platforms, and tooling is essential for migration success. AWS, Microsoft Azure, and Google Cloud Platform continue to dominate, and over half of organisations rely on Managed Service Providers (MSPs) to operate cloud environments. Adopting FinOps practices — with 59% of firms maintaining a dedicated FinOps function — supports cost governance. At the same time, enterprises are prioritising AI enablement and serverless patterns to capitalise on cloud-native capabilities and streamline operations.
By adopting these cloud migration best practices for 2025, IT executives can execute a thoughtful and effective move to the cloud, realising benefits in cost reduction, agility, and sustainability.
