Yearly/Monthly subscription - prepaid.
Pay-as-you-go - postpaid.
Billable item
Based on supported cluster specifications, including TPS, bandwidth, and fixed storage fees.
Based on supported cluster specifications, including TPS, bandwidth, and storage pay-as-you-go fees.
API call fees, message storage fees, and partition topic usage fees.
Sending/Receiving TPS 
Purchased as required based on different computing and storage specifications (2,000 TPS at least).
Purchased as required based on different computing specifications (1,000 TPS at least).
The TPS for production and consumption on a single topic in a cluster is limited to 5,000, respectively.
Storage
Message persistence is required, resulting in stable storage consumption.
Messages are deleted after being consumed in most scenarios. Storage consumption is small or fluctuates greatly.
Storage is used in pay-as-you-go mode.
Network
Multiple VPC routes and public network access routes are supported.

Capacity Assessment
After the selected cluster type is confirmed, you need to evaluate the instance specifications required for actual business operations, including computing specifications and storage specifications.
Computing specifications: The computing specifications of TDMQ for Apache Pulsar Pro Edition indicate the maximum TPS for message sending and receiving, and the maximum bandwidth of the cluster instance. You need to select appropriate computing specifications based on actual business operations.
Storage specifications: You can estimate the message volume and size based on the business volume and calculate the required storage space. For pro clusters (fixed storage), the storage capacity is fixed, and yearly/monthly subscription is used. For pro clusters (elastic storage), storage is billed in pay-as-you-go mode. However, clusters of different specifications have different storage upper limits.
TDMQ for Apache Pulsar Pro Edition uses 3 replicas for message storage by default. Note this during the assessment.
