Enterprise Cloud Migration
Zero-downtime migration to AWS cloud
Overview
Migrated critical financial systems to AWS with zero downtime and strict cost optimization.
Challenge
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.
Solution
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.
