AWS re:Invent 2025 - A leader's guide to accelerating large-scale migration (SNR301)

Accelerating Large-Scale Cloud Migration: Insights from an Expert

The Challenge of Cloud Adoption

• Despite cloud computing generating over $100 billion in annual revenue, 85% of global IT spend is still on-premises
• The presenter, Jake Burns, has spent the last 10 years analyzing why cloud migration is so difficult for organizations

The Presenter's Background and Successful Migration Experience

• Jake Burns was previously the CIO at Live Nation Ticketmaster, where he led an "all-in" migration to AWS
• The migration was completed in 17 months, despite a 12-month deadline, no budget, and a team with no cloud experience
• Key results included:
  • 50% reduction in total cost of ownership after optimization
  • Improved availability, resilience, and performance

Six Pillars of Successful Cloud Migrations

1. Compelling Why: The migration must be driven by a mission-critical business objective, not just cost savings
2. Utilize Constraints: Tight deadlines and limited resources can actually drive innovation and success
3. Invest in People: Upskilling the existing workforce is crucial for effective cloud adoption
4. Embrace Simplicity: Excess complexity is the root cause of many failed migrations
5. Strong Leadership: Accountable leaders with the authority to make decisions are essential
6. Build Momentum: Early wins and a sense of urgency are key to gaining buy-in and sustaining progress

Overcoming Common Objections

• Objections like "it won't work for our industry" or "we have unique regulatory requirements" are often based on assumptions and complexity
• Cloud migration is fundamentally about moving applications and data, which is similar to past data center consolidations

The Power of Constraints

• Organizations are more likely to fail from too many resources and too much time, rather than too few
• Tight deadlines and limited budgets force focus, innovation, and efficiency
• The presenter was able to achieve impressive results by starting before feeling fully ready and working backwards from a tight deadline

Upskilling the Existing Workforce

• The presenter did not hire any cloud experts, but instead developed the skills of his existing team
• This approach creates a sustainable pipeline of cloud talent and a sense of ownership
• Key strategies include:
  • Providing training and a "safety net" to address fears
  • Outsourcing undifferentiated work to free up time for cloud initiatives
  • Fostering buy-in through a compelling vision and shared ownership

A Simplified Migration Framework

• The presenter advocates for a lean, three-part structure:
  1. A dedicated "cloud team" responsible for the hands-on migration
  2. A lightweight "advisory board" to align on policies and governance
  3. Engaged "stakeholders" (application owners) who provide input and testing
• This approach avoids complex committees and organizational structures

Minimal Viable Refactoring (MVR)

• Rather than the traditional "7 Rs" model, the presenter recommends a "1-hour" model of minimal viable refactoring
• The goal is to do just enough refactoring to improve security, compliance, reliability, performance, and cost - no more
• This allows for a faster, more iterative migration process, with the bulk of modernization happening after the initial cloud migration

Key Principles for Successful Migrations

• Go fast, but not without planning - get to the cloud quickly, then optimize
• Use constraints to drive innovation, not just effort
• Focus on building momentum through early wins and a sense of urgency
• Invest in upskilling the existing workforce to create a sustainable cloud talent pipeline
• Decouple migration and modernization to simplify the process and reduce risk

Real-World Impact and Examples

• The presenter's experience at Live Nation Ticketmaster resulted in a 50% reduction in total cost of ownership and improved performance
• By applying these principles, the presenter has been able to replicate successful cloud migrations across various industries and organizations
