Apps Sr. Architect - Lumen Data Center Exit

1. Application Strategy & Architecture Leadership

• Define and govern enterprise application exit strategy and migration roadmap
• Lead application architecture inputs for the Migration Readiness Blueprint
• Ensure alignment with:

• Business priorities
• Cloud-first strategy (AWS target platform)
• TSA exit timelines

2. Application Inventory & Discovery Governance

• Drive validation of:

• Application landscape, workloads, and associated infrastructure

• Ensure complete mapping of:

• Application purpose
• Business criticality
• Hosting and infrastructure dependencies

• Collaborate with DC Architect for infrastructure validation alignment

3. Dependency Mapping & Integration Architecture

• Lead identification and documentation of:

• Upstream/downstream integrations (APIs, DB links, batch jobs, SFTP feeds)
• Data flows and authentication dependencies

• Build and govern end-to-end application dependency matrix
• Address complex:

• App-to-app
• App-to-database
• App-to-identity dependencies

4. Workload Disposition Strategy (6R Ownership for Apps)

• Define application-level disposition strategy:

• Rehost, Re-platform, Rebuild, Retain, Retire

• Evaluate based on:

• Technical feasibility
• Business impact
• Cost and modernization potential

• Identify:

• Legacy application constraints
• Licensing restrictions
• Enviri shared dependencies and TSA blockers

5. Application Modernization & Cloud Alignment

• Define target-state application architecture aligned to:

• AWS services (EC2, RDS, S3, Lambda)

• Recommend:

• Re-platforming or modernization opportunities
• API-driven, microservices, or cloud-native architecture (where applicable)

• Identify workloads requiring:

• Hybrid or alternative hosting models

6. Data Flow & Data Migration Strategy

• Analyze and define:

• Application-level data flows and integration patterns
• Data volumes and retention requirements

• Provide architecture for:

• Data migration
• Data archival and disposition

• Align with data and cloud teams on:

• Database migration approach
• File storage movement strategy

7. Migration Wave Planning & Execution Strategy

• Define application-aware migration wave strategy:

• Group workloads based on dependency clusters

• Establish:

• Cutover approach
• Rollback procedures
• Business validation checkpoints

• Ensure migration sequencing minimizes:

• Application downtime
• Business disruption

8. Application Risk, Constraints & Governance

• Own:

• Application-level risk, assumptions, and constraints register

• Identify risks such as:

• Legacy OS dependencies
• Tight app-database coupling
• Hardcoded integrations

• Define mitigation strategies and escalation plans

9. Cross-Workstream Coordination & Leadership

• Drive alignment with:

• DC Architect (infra readiness)
• Cloud Architect (target platform)
• Identity & Security teams (SSO, authentication)

• Ensure dependencies across:

• Identity (WS1), Cloud (WS2), Network (WS5) are addressed before migration

10. Stakeholder Engagement & Executive Communication

• Communicate architecture decisions and risks to:

• Business stakeholders
• Program leadership

• Provide:

• Executive summaries
• Decision support artifacts

• Drive application-level sign-offs for migration readiness

Key Deliverables
