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.
