    Hands-On Lab Exercise

    Lab: Building a Cloud Migration Business Case

    Objective: Develop a business case document for migrating a fictional company's IT infrastructure to the cloud.

    Scenario: TechRetail Inc. is a growing e-commerce company with the following current infrastructure:

    • 20 on-premises servers (average utilization: 30%)
    • Annual IT infrastructure costs: $500,000 (hardware, maintenance, staff, power, cooling)
    • Experiences 4x traffic spikes during holiday sales
    • Has experienced 3 unplanned outages in the past year (average downtime: 6 hours each)
    • Plans to expand to 2 new international markets next year

    Instructions:

    1. Current State Assessment (20 min): Document the current IT challenges TechRetail faces, including underutilization, scalability limitations, and reliability issues.
    2. Cloud Solution Design (20 min): Propose a cloud architecture using at least two service models (IaaS, PaaS, or SaaS). Specify which workloads would use which model and justify your choices.
    3. Cost Analysis (20 min): Create a 3-year TCO comparison between maintaining the current on-premises setup versus migrating to cloud. Use the following assumptions:
      • Cloud equivalent cost: $25,000/month base + auto-scaling costs during peaks
      • Migration cost: $75,000 one-time
      • On-premises growth cost: $150,000/year for new hardware to support expansion
    4. Risk Assessment (15 min): Identify at least 5 risks of cloud migration and propose mitigation strategies for each.
    5. Executive Summary (15 min): Write a one-page executive summary recommending cloud adoption, supported by your analysis.

    Deliverables:

    • Written business case document (3–5 pages)
    • TCO comparison table or spreadsheet
    • Risk assessment matrix
