Vanguard framework

Cloud transformation without unnecessary risk.

Vanguard Cloud Architecture organizes cloud modernization into six connected phases so business leaders and technical teams can make decisions from the same plan.

Six phases of Vanguard Cloud Architecture: Discover, Assess, Architect, Migrate, Secure, and Optimize
Framework principles

One transformation plan from business case to operations

Each phase produces practical outputs that guide the next phase, while security, continuity, cost, and governance remain visible throughout.

1

Discover

Objective: Build a fact base for decision-making.

  • Business goals and constraints
  • Servers, networks, storage, applications, and databases
  • Dependencies and data flows
  • Security concerns and performance issues
  • Current operating and cost model

Outcome: A documented current-state view and agreed transformation objectives.

2

Assess

Objective: Determine migration readiness, complexity, and priority.

  • Workload classification
  • Migration-strategy selection
  • Compliance and security requirements
  • Risk and dependency analysis
  • Cost estimation and migration sequencing

Outcome: A prioritized migration portfolio with clear assumptions and decision points.

3

Architect

Objective: Design the target environment and operating controls.

  • Cloud platform and service selection
  • Network and connectivity architecture
  • Identity and access management
  • Security, recovery, monitoring, and cost controls
  • Governance and automation standards

Outcome: A secure target architecture and implementation plan.

4

Migrate

Objective: Move workloads through controlled, validated waves.

  • Pilot workload
  • Data and application migration
  • Testing and acceptance criteria
  • Cutover communication
  • Rollback and downtime planning

Outcome: Validated workloads operating in the target cloud environment.

5

Secure

Objective: Validate and strengthen cloud security controls.

  • Least-privilege access
  • Encryption and secrets management
  • Logging and threat detection
  • Vulnerability and configuration review
  • Backup security and recovery validation

Outcome: A documented security baseline and prioritized improvement actions.

6

Optimize

Objective: Improve cost, performance, automation, and governance.

  • Rightsizing and utilization review
  • Performance monitoring
  • Operational automation
  • Budgeting and tagging
  • Governance and continuous improvement

Outcome: A sustainable operating model with measurable improvement priorities.

How the framework reduces avoidable risk

Vanguard does not assume every workload belongs in the same cloud service or should migrate in the same way. It creates decision points for retaining, retiring, replacing, rehosting, replatforming, or refactoring systems based on business value, complexity, security, and cost.

Decision gates

  • Is the business case clear enough to proceed?
  • Are dependencies and data flows understood?
  • Has the target architecture been reviewed?
  • Are rollback and continuity plans credible?
  • Have security and operational controls been validated?
  • Are ownership, monitoring, and cost controls in place after migration?
