Cloud Message Queues
Managed queue services — AWS SQS, Google Pub/Sub — durable scalable queuing without managing RabbitMQ infrastructure.
6mo ago Cloud intermediate
Cloud Monitoring Tools 🧠 2
CloudWatch (AWS), Cloud Monitoring (GCP), Azure Monitor — auto-collect infrastructure metrics but need explicit instrumentation for application metrics.
