7 Azure Cloud Migration Challenges Every Engineer Should Know (And How to Fix Them)
Short summary
Azure migrations commonly fail due to inadequate workload discovery, poor right-sizing, and security regression. Essential solutions include using Azure Migrate for dependency mapping, applying the 6Rs framework per workload, establishing FinOps practices, and running multiple cutover rehearsals. Organizations implementing these disciplines typically achieve 25-40% cost reductions within the first year post-migration.
- •Run workload discovery with Azure Migrate before migration; use the 6Rs framework to match strategy to each workload type
- •Establish security baseline and cost management from day one; Microsoft Defender for Cloud provides compliance mapping (ISO 27001, SOC 2, PCI DSS)
- •Execute at least two full cutover rehearsals; implement FinOps practices for 25-40% cost reduction within first year
