Last updated: 2025-11-03 15:49:29
This document introduces the billing mode and pricing of CKafka private network bandwidth.
Project | Applicable Scope | Description | Billing Mode |
Peak bandwidth (required) | full series | For private network bandwidth, estimate the peak bandwidth resource amount by calculating peak business traffic bandwidth × number of replicas. CKafka accumulates bandwidth usage of all replicas to calculate the actual peak bandwidth. For example, if the business requires 40MB bandwidth with 3 replicas, purchase 120MB/s peak bandwidth is required. | Monthly Subscription, hourly billing |
Elastic bandwidth (optional) | Professional Edition | Once enabled, if business traffic exceeds the purchased cluster bandwidth specification, the excess usage will be billed as pay-as-you-go. No fee is charged if the traffic stays within the specification. Suitable for scenarios where the business side occasionally experiences sudden traffic spikes. | Pay-as-You-Go |
Peak Bandwidth Price
Peak bandwidth is billed by different tiers. The pricing tiers are as follows:
Product Version | Peak Bandwidth Range (MB/S) | Monthly Subscription Unit Price | Hourly Billing Unit Price |
Advanced Edition | 20 | 63.5714USD/month | / |

| 120 ~ 300 | 241.2143USD/month starting, +6.4286USD/month per 20MB/s | |
| 320 ~ 360 | 439.0714USD/month starting, +5.7143USD/month per 20MB/s | |
Professional Edition | 20 | 167USD/month | 0.26USD/hour |
| 40 ~ 100 | 360USD/month starting, +53USD/month per 20MB/s | 0.55USD/hour starting, +0.09USD/hour per 20MB/s |
| 120 ~ 300 | 630USD/month starting, +51USD/month per 20MB/s | 0.96USD/hour starting, +0.08USD/hour per 20MB/s |
| 320 ~ 600 | 1200USD/month starting, +49USD/month per 20MB/s | 1.83USD/hour starting, +0.07USD/hour per 20MB/s |

Example: A Pro Edition instance with 180MB/s, using the Monthly Subscription billing mode, adds 60MB/s on the basis of 120MB/s. The package price is 630 + 51 × ( 60 / 20 ) = 783USD/month.
Elastic Bandwidth Pricing
The elastic bandwidth billing mode is pay-as-you-go. Once enabled, no fee is charged if unused. Elastic bandwidth billable items consist of two parts: elastic production traffic and elastic consumption traffic. The related billing modes are shown in the table below:
Billing Item | Unit Price | Calculation Formula | Settlement Method |
Production Elastic Cost | 0.0064USD/GB/hour | Total production traffic (GB) (excluding traffic generated by replicas) × Elastic pricing (USD/GB) × Number of replicas | Settled hourly Daily push billing |
consumption elasticity fee | 0.0064USD/GB/hour | Total elastic consumption traffic (GB) (excluding traffic generated by replicas) × Elastic pricing (USD/GB) | Settled hourly Daily push billing |
