Cloud Egress Shockwave
An exponential cloud billing crisis caused by unmetered cross-AZ or cross-region data transfer during distributed failovers or data pipelines.
Detailed Explanation
Cloud providers charge aggressively for data leaving regions or crossing availability zones. When a high-throughput microservice mesh or analytics job routes traffic across regions without VPC peering or caching, the monthly egress bill can exceed the entire company revenue.
Why It Matters
Egress fees are silent and unbounded, often discovering architectural mistakes only when the monthly billing alert triggers.
Common Failure Mode
Practical Example
Production Manifestation
Surprise six-figure monthly cloud invoices with 80% attributed to inter-region network transfer.
