Zero-downtime migration to AWS cloud
Migrated critical financial systems to AWS with zero downtime and strict cost optimization.
FinanceHub operated critical financial systems on legacy infrastructure with high costs and limited scalability.
Migration needed to maintain zero downtime while ensuring data security and regulatory compliance.
Executed phased cloud migration strategy: assessed workloads, designed AWS architecture (multi-AZ, auto-scaling), implemented CI/CD pipelines, migrated databases with replication, optimized costs with Reserved Instances.
