Challenge
On-premises data centre lease expiring in 18 months with 200+ servers to migrate, strict regulatory compliance requirements, and a legacy monolith that had never run outside the data centre.
Our Approach
Sort Tree conducted a workload assessment, designed a phased migration plan, containerised the core monolith, and migrated all workloads to AWS within 14 months using infrastructure-as-code throughout.
Outcome
Full data centre exit completed 4 months ahead of deadline. Infrastructure costs reduced by 38%. Deployment frequency increased from monthly to daily.

Key Results

  • Full data centre exit 4 months ahead of deadline
  • 38% reduction in infrastructure costs
  • Deployment frequency increased from monthly to daily
  • 99.95% application availability post-migration
