Reasons buyers look elsewhere
- Pricing scales unpredictably with message volume — teams sending >1M messages/month often switch to Google Pub/Sub or Azure Service Bus for predictable per-GB rates
- Strict HIPAA or GDPR requirements push organizations toward services with explicit data residency guarantees and audit logs — SNS regional replication doesn't satisfy all compliance frameworks
- Need for real-time analytics dashboards and native Kafka integration drives teams to Confluent Cloud or RabbitMQ, which offer built-in observability SNS requires third-party tools to match
