Cloud Migration Strategies That Actually Reduce Costs in 2026

Cloud migration done well delivers significant cost savings, improved reliability, and the ability to scale on demand. Done poorly, it creates complexity, unexpected bills, and operational headaches. Here is how to do it right.

Start with a Cloud Readiness Assessment

Before migrating anything, you need a clear picture of your current infrastructure. A cloud readiness assessment maps every workload, identifies dependencies, and classifies applications by migration complexity.

The output is a prioritised migration roadmap — move the straightforward workloads first to build confidence and capability before tackling the complex ones.

The 6 Rs of Cloud Migration

**Rehost (Lift and Shift)** — Move workloads to the cloud as-is. Fastest approach, but leaves performance and cost optimisation for later.

**Replatform** — Make targeted optimisations during migration without changing core architecture. A good middle ground.

**Repurchase** — Replace an existing application with a cloud-native SaaS alternative.

**Refactor** — Redesign the application architecture to be cloud-native. Highest effort, highest long-term benefit.

**Retire** — Decommission applications that are no longer needed.

**Retain** — Keep some workloads on-premise where cloud migration does not make sense.

Choosing the Right Cloud Platform

AWS, Azure, and GCP all have compelling offerings. The right choice depends on your existing technology stack, compliance requirements, and geographic needs. Our architects are certified across all three and will give you an honest recommendation.

Cost Optimisation from Day One

Right-sizing is the single biggest lever. Most organisations significantly overprovision compute resources. Running workloads for 2–4 weeks and analysing actual utilisation typically reveals significant right-sizing opportunities.

Reserved instances for stable workloads, spot instances for interruptible jobs, and automated start/stop schedules for non-production environments can collectively reduce your cloud bill by 40–60%.

Ensuring Zero-Downtime Migration

Our migration methodology uses blue-green deployment to achieve zero-downtime migrations for production systems. The new environment is built and tested in parallel before traffic is switched over.

Post-Migration Optimisation

Migration is not the end — it is the beginning. The first 90 days post-migration typically reveal additional optimisation opportunities. Our managed services team monitors performance, cost, and security continuously.
