AWS re:Invent 2025: Liberty Puerto Rico Builds Resilient Hybrid Telecom Infrastructure with AWS Outposts

AWS re:Invent 2025 - Build resilient and low-latency hybrid telecom infrastructure at scale (HMC328)

Liberty Puerto Rico deployed a hybrid telecom infrastructure using AWS Outposts, achieving 15-millisecond latency for real-time charging systems. The solution supports 2 million mobile subscribers with active-passive failover between Puerto Rico and Miami.

Why This Matters

Legacy telecom systems often rely on monolithic, print-based architectures with slow time-to-market and high customization costs. Liberty’s cloud-native approach using Matrixx and AWS Outposts reduces latency by 80% compared to traditional systems, while active-passive architecture ensures zero downtime during hurricanes. The cost of downtime in telecom networks can exceed $10M/hour, making resilience a critical business requirement.

Key Insights

• “2 million subscriber migration from AT&T legacy systems, 2019”
• “Active-passive architecture with 15ms latency for real-time charging”
• “AWS Outposts used with Matrixx, F5, MongoDB, and EKS in Puerto Rico and Miami”
• “Subsea fiber (Arcos and Americas 2) enables 10ms latency between on-premises and AWS Miami”

Practical Applications

• Use Case: Liberty Puerto Rico’s hybrid architecture enables seamless failover during hurricanes using AWS Direct Connect and subsea fiber.
• Pitfall: Over-reliance on proprietary subsea infrastructure may limit scalability without redundant third-party connectivity options.
