☁️ 1. Why Choose Azure for Migration?

Top Benefits:

  • Deep integration with Microsoft tools (AD, O365, Windows Server)
  • Extensive global reach with 60+ regions
  • Built-in security controls and compliance certifications
  • Hybrid capabilities via Azure Arc and Azure Stack

Use Case:
A financial firm moved its on-prem SQL workloads to Azure SQL Managed Instance, enabling auto-patching, encryption, and high availability.

🔐 2. Pre-Migration Security Planning

  1. a) Assess Risks:
  • Perform a security audit of on-prem infrastructure
  • Identify sensitive data and regulatory requirements
  1. b) Secure Identities & Access:
  • Integrate on-prem AD with Azure AD
  • Enforce MFA, Conditional Access, and role-based policies
  1. c) Network Security:
  • Plan NSGs, firewall rules, and private endpoints

Design VNET peering for secure interconnectivity

🧭 3. Step-by-Step: Secure Azure Migration Process

✅ Step 1: Discovery & Assessment

  • Use Azure Migrate to inventory VMs, databases, and apps
  • Define migration readiness and group dependencies

✅ Step 2: Planning & Design

  • Choose the right migration strategy:
    • Rehost (lift and shift)
    • Refactor (containerize)
    • Rearchitect (modernize)
  • Design target Azure architecture with NSGs, ASGs, VPN, ExpressRoute

✅ Step 3: Data Protection & Backup

  • Enable Azure Backup for all critical workloads
  • Use Azure Key Vault to store secrets & certificates securely
  • Encrypt data at rest and in transit (TLS, disk encryption)

✅ Step 4: Migration Execution

  • Migrate workloads using tools like:
    • Azure Migrate: Server Migration
    • Database Migration Service (DMS)
  • Monitor migration status using Azure Monitor & Log Analytics

✅ Step 5: Post-Migration Optimization

  • Perform penetration testing & vulnerability scans
  • Enable Microsoft Defender for Cloud for continuous security posture
  • Optimize cost with Azure Advisor and reserved instances
