Case Studies & Success Stories
Explore real-world examples of successful Azure migrations, with detailed context, challenges, solutions, and outcomes.
Example 1: Retail Company Rehosting
- Background: A mid-sized retail company operated a legacy e-commerce platform hosted on-premises, facing frequent outages and high maintenance costs. The IT team had limited cloud experience and a tight migration timeline due to expiring data center contracts.
- Challenge:
- Aging hardware and unsupported software.
- High operational costs and limited scalability during peak sales.
- Need to minimize downtime and risk during migration.
- Solution:
- Conducted an initial assessment using Azure Migrate to inventory VMs and dependencies.
- Chose a Rehost (lift-and-shift) strategy, moving VMs and databases to Azure IaaS with minimal changes.
- Used Azure Site Recovery for seamless VM migration and failback testing.
- Implemented Azure Backup and Azure Monitor for post-migration resilience and visibility.
- Outcome:
- Reduced infrastructure costs by 30%.
- Improved scalability and disaster recovery capabilities.
- Achieved migration with less than 2 hours of downtime.
- Enabled future modernization by establishing a cloud foundation.
Example 2: SaaS Provider Refactoring
- Background: A SaaS provider delivered a monolithic web application to hundreds of clients, but struggled with slow release cycles, scaling issues, and high support overhead.
- Challenge:
- Monolithic architecture hindered feature releases and bug fixes.
- Manual scaling led to performance bottlenecks during customer onboarding.
- Security and compliance requirements were increasing.
- Solution:
- Performed an application assessment and identified key services for refactoring.
- Adopted a Refactor strategy, breaking the monolith into microservices using Azure App Service and Azure SQL Database.
- Leveraged Azure DevOps for CI/CD automation and Azure Key Vault for secrets management.
- Integrated Azure Application Gateway and Azure Security Center for enhanced security and monitoring.
- Outcome:
- Accelerated deployment cycles from monthly to weekly.
- Improved reliability and reduced support tickets by 40%.
- Achieved better resource utilization and cost efficiency.
- Enhanced compliance posture with built-in Azure security features.
Example 3: Financial Services Assessment
- Background: A financial services firm needed to migrate sensitive workloads to Azure while meeting strict regulatory and data residency requirements.
- Challenge:
- Ensuring compliance with industry regulations (e.g., GDPR, PCI DSS).
- Data residency and encryption requirements for customer data.
- Zero tolerance for downtime during migration.
- Solution:
- Used Azure Migrate and the Cloud Adoption Framework (CAF) to assess workloads, risks, and compliance gaps.
- Designed a migration plan with staged cutovers and extensive testing.
- Leveraged Azure Policy, Azure Blueprints, and Azure Security Center to enforce compliance and governance.
- Employed Azure Database Migration Service for secure, validated data transfer.
- Outcome:
- Achieved regulatory compliance and passed external audits.
- Migrated critical workloads with zero unplanned downtime.
- Improved data security and monitoring with Azure-native tools.
- Gained agility to respond to new business and regulatory needs.
