Why Cloud Migration Strategy projects fail

01

On-premise infrastructure limiting growth

Scaling requires hardware procurement cycles. Disaster recovery is expensive and untested. Remote work performance is poor. The infrastructure is a growth bottleneck, not an enabler.

02

Cloud provider chosen before strategy was designed

AWS or Azure selected based on an existing commercial relationship, not a requirements analysis. Twelve months later the platform does not fit the workload characteristics and migration would be costly.

03

Cloud costs spiralled above on-premise baseline

The move to cloud was projected to reduce infrastructure costs. Eighteen months in, cloud costs are 40% higher than the on-premise baseline because nobody modelled the cloud cost architecture before committing.

04

Security and compliance not designed in

Customer and financial data moved to cloud without reviewing data residency requirements, encryption standards, access control design, or regulatory obligations. Audit findings followed within 6 months.

How it works

Our delivery process

01

Readiness assessment

Inventory every application, data asset, and integration dependency. Identify compliance, security, and cost considerations before planning begins.

02

Platform selection

Evaluate cloud platforms against your specific workload requirements and compliance context -- not vendor preference.

03

Cost modelling

Model the full cloud cost architecture before committing -- compute, storage, egress, support, and operational overhead included.

04

Phased migration

Execute migration in phases with defined success criteria, parallel running, and active rollback capability throughout.

05

Cost optimisation

Review and optimise cloud costs 90 days post-migration -- right-sizing, reserved instances, storage tiering, and governance.

All case studies

The cloud cost model Celumai built before we committed to AWS identified a design pattern that reduced our projected monthly cost by 35%. That analysis alone paid for the entire engagement. We have not had a single cost surprise since go-live.

Logistics Company

We migrated 14 applications across 6 months with zero unplanned downtime. The phased approach meant the business barely noticed. More importantly, the compliance documentation they produced satisfied our ISO 27001 auditors completely.
