Azure Event Hubs vs Service Bus cost: streaming vs messaging pricing
Event Hubs prices by throughput units for high-volume streaming, while Service Bus prices by operations and messaging units for enterprise messaging. They solve different problems at very different cost curves. Here is how to compare them.
GCP Pub/Sub Lite vs Pub/Sub cost: when the cheaper tier pays off
Pub/Sub bills per gigabyte of message throughput with no capacity planning, while Pub/Sub Lite bills for provisioned capacity at a much lower unit rate. Here is how the two compare on cost and when Lite's savings justify its extra management.
SQS vs SNS vs EventBridge cost: pricing three messaging services
SQS, SNS, and EventBridge all move messages between services but price differently, per request, per publish and delivery, and per event with routing. Which is cheapest depends on your fan-out and routing needs. Here is the comparison.
Amazon MQ cost: broker instance hours plus storage

Message queue cost compared: SQS vs Pub/Sub vs Service Bus
SQS, Google Pub/Sub, and Azure Service Bus price messaging differently, SQS per request, Pub/Sub per TiB of throughput, Service Bus per operation or messaging unit. This compares the models and the surprises in each.
GCP Cloud Tasks cost: cheap per operation, free tier included
Cloud Tasks bills per operation (task creation and dispatch), with the first million operations free each month and about $0.40 per million after. It is inexpensive; the cost to watch is the work the tasks trigger. Here is the model.
GCP Pub/Sub cost: you pay per terabyte of message throughput
Pub/Sub bills about $40 per TiB of throughput (publish plus subscribe), with the first 10 GB free, plus storage for retained messages and egress. Throughput volume drives the bill, so batching and trimming payloads are the levers. Here is the breakdown.
Azure Service Bus cost: Basic, Standard, and Premium messaging units
Service Bus Basic and Standard bill per operation (plus a base fee on Standard), while Premium bills per messaging unit by the hour for predictable performance. Here is how the tiers price and when Premium is worth its fixed cost.
SQS vs SNS vs EventBridge cost: pick by pattern, not price
SQS is $0.40/M, SNS $0.50/M, EventBridge $1.00/M, but they do different jobs. Here's the cost ranking, when EventBridge's premium is worth it, and how to keep messaging cheap at scale.
