Project Overview

In this engagement, AEITCH provided a comprehensive solution for migrating the client’s existing Azure infrastructure, including a large database and virtual machines (VMs), to a new region within the Azure platform. The migration aimed to enhance performance, improve redundancy, and ensure compliance with regional regulations.

The Challenge

Migrating a large-scale Azure infrastructure involving databases, VMs, and other resources to a new region presents several challenges, including:

  • Minimizing downtime and ensuring seamless operations during the migration process
  • Maintaining data integrity and consistency across the migration
  • Ensuring the new environment is thoroughly tested and validated before going live
  • Managing the increased costs associated with running parallel environments during the migration phase

Solution Architecture

AEITCH proposed a structured approach leveraging Azure’s native migration tools and best practices to address the client’s migration requirements effectively.

Migration Phases

  1. Replica Environment Setup:
    • Creation of a replica environment in the Dubai region, including:
      • Two web app migrations
      • Storage migration (Blob Storage)
      • Azure SQL Database migration (10GB)
  2. Testing and Validation:
    • Thorough testing of the new environment by the client’s development team and stakeholders
    • Validation of functionalities, integrations, and data flows
  3. DNS Update and Cutover:
    • Selection of an optimal time window with minimal traffic
    • Update of DNS records to point to the new environment in the Dubai region
  4. Decommissioning Old Environment:
    • Decommissioning and deletion of the old infrastructure in the Europe region
    • Optimization of costs by removing redundant resources

Cost Management

During the migration phase, AEITCH implemented cost optimization strategies to minimize the additional expenses incurred while running parallel environments for testing and validation purposes.

Benefits and Advantages

By leveraging AEITCH’s expertise in Azure migrations and best practices, the client benefited from:

  • Minimized downtime and seamless operations during the migration process
  • Ensured data integrity and consistency across the migration
  • Thorough testing and validation of the new environment before going live
  • Efficient management of increased costs during the migration phase
  • Improved performance, redundancy, and compliance with regional regulations

AEITCH’s structured approach, combined with Azure’s robust migration tools and capabilities, enabled a successful migration of the client’s infrastructure to the new region, meeting their business objectives.
