## Buyer Intent Signals
Problems: Custom Database Queuing/MSMQ: Using localized message queues like MSMQ or custom-built SQL-based polling tables for inter-service communication. | Synchronous-Only Architecture: Relying on direct synchronous API calls (HTTP/gRPC) between services without any buffering or asynchronous mediation.
Solutions: enterprise cloud message broker | managed AMQP 1.0 queue service | reliable pub/sub for microservices | best messaging service for .NET applications | Self-Hosted RabbitMQ/Kafka: Building and maintaining a self-hosted RabbitMQ or Apache Kafka cluster on virtual machines or on-premises servers.
