Large-Scale Migration from On-Prem to Cloud
Enabling scalability, security, and operational efficiency through cloud-native modernization.
Overview
A leading banking enterprise depended on on-premise legacy systems, siloed data stores, and aging infrastructure. They partnered with Mehtalogy to design and execute a secure, phased, and zero-data-loss cloud migration—while modernizing critical platforms to cloud-native architectures.
Challenges
- Complex legacy systems running on aging hardware
- High operational cost and limited scalability on-prem
- No centralized monitoring or unified DevOps processes
- Disparate databases across multiple business units
- Downtime constraints requiring near-zero disruption
- Security, compliance, and audit readiness requirements
Solution Delivered
Mehtalogy delivered an end-to-end cloud migration program with strong emphasis on automation, containerization, and future-proof architecture.
Cloud Readiness & Architecture
Comprehensive assessment of all apps & databases, followed by a cloud-native reference architecture based on Azure/AWS.
Containerization & AKS
Legacy services containerized and deployed using AKS/EKS for maximum scalability, resiliency, and simplified CI/CD pipelines.
DevOps Automation & CI/CD
Infrastructure-as-Code (IaC) via Terraform + GitOps workflows ensured repeatable, secure deployments.
Unified Observability
Centralized dashboards using Azure Monitor, Grafana, and Elastic for monitoring, alerting, and long-term analytics.
Migration Approach
- Workload classification (Rehost / Refactor / Rebuild)
- Data migration using DMS, replication, and staging pipelines
- Pilot testing with rollback-safe deployments
- Progressive migration of services in controlled waves
- Near-zero-downtime cutover strategy
Impact Delivered
60% Lower Costs
Reduction in hardware, licensing, and maintenance overhead.
Modernized Stack
Migrated legacy apps to containerized microservices using cloud-native infrastructure.
Stronger Security
Zero-trust model, cloud IAM, and improved audit readiness.
