Shattering AWS’s 250K-IP Ceiling: How Data 360 Reached 1 Million IPs with Zero-Downtime Migration

Summary

The article discusses the engineering challenges faced by the Data 360 team at Salesforce in overcoming AWS's 250,000-IP limit through innovative architectural strategies. The team implemented prefix delegation to efficiently manage IP allocation while ensuring zero downtime during migration. Key considerations included navigating Hyperforce's strict architectural constraints and developing custom observability tools to monitor the new IP allocation model. This approach not only allowed for scaling beyond the existing limits but also established a repeatable pattern for future hyperscale workloads.

Key Learnings

• 1Prefix delegation can significantly enhance IP allocation efficiency but requires careful management to avoid fragmentation.
• 2Collaboration with cloud providers and internal teams is crucial for tailoring solutions to specific architectural constraints.
• 3Custom observability tools are essential for monitoring complex migrations and ensuring workload safety.
• 4Architectural constraints can transform scaling challenges into opportunities for innovative solutions.
• 5Establishing a dedicated SFSG for specific expansion requirements can facilitate compliance with existing security and routing models.
