Azure Migration Leadership & Architecture

• Architect and deliver Azure migrations using Azure Migrate and Azure Site Recovery for Windows and Linux workloads.
• Design Azure Landing Zones with hub-spoke networks, governance (Azure Policy, Blueprints), and security (Key Vault, NSGs).
• Lead migration planning, runbook creation, testing, cutover, rollback, and post-migration validation.
• Configure Azure Site Recovery for disaster recovery, setting replication policies and automated failover.
• Perform complex cluster migrations to Azure, managing shared disk and quorum configurations.
• Develop Terraform and ARM templates to standardize Azure deployments and reduce provisioning time.
• Create PowerShell and Azure CLI scripts for migration assessments and bulk tasks, improving efficiency by 60%.
• Conduct Azure TCO and cost optimization reviews, recommending right-sizing and reserved instances.
• Prepare technical design documents, architecture diagrams, and operational procedures for Azure migrations.

Multi-Cloud Migration Expertise

• Lead GCP Guild, designing landing zones with Terraform and migrating workloads using M2VM.
• Deploy Stratozone for cloud readiness, dependency mapping, and right-sizing in GCP.
• Manage Google Cloud lab for migration validation and use case testing.
• Architect hybrid cloud solutions with GCVE for VMware workloads on GCP.
• Implement AWS MGN for agent-based migrations of physical and virtual servers.
• Configure Zerto for migrations to vCenter, AWS, and Azure, including complex workload transitions.
• Deploy VMware HCX in multi-vCenter setups for bulk migration and vMotion scenarios.
• Use Carbonite Move for application-aware physical server migrations with minimal downtime.

Migration Lifecycle Management

• Facilitate workshops to define migration governance, RACI matrices, and RAID logs.
• Conduct discovery and assessment using Cloudscape, Stratozone, and native cloud tools.
• Develop migration wave strategies balancing dependencies, priorities, and risk.
• Coordinate cross-functional teams during migration execution.
• Deliver hypercare support post-migration, monitoring performance and troubleshooting.
• Create migration playbooks, SOPs, and knowledge transfer materials for client IT teams.
