FAQ
What are Elastic CKUs (eCKUs) and why are they important?
Elastic Confluent Units for Kafka (eCKUs) are a unit of horizontal scalability in Confluent Cloud. eCKUs autoscale up to meet spikes in demand and back down based on workload with no user intervention required, and you only pay for the resources you use when you actually need them. Never worry about cluster sizing and provisioning or overpaying for resources again. Autoscaling eCKUs provide a truly serverless experience to save you time and money, enabling you to focus on innovation and business logic while simultaneously lowering costs.
How is my monthly bill calculated?
Confluent monthly bills are based upon resource consumption, i.e., you are only charged for the resources you use when you actually use them:
- Stream: Kafka clusters are billed for eCKUs/CKUs ($/hour), networking ($/GB), and storage ($/GB-hour).
- Connect: Use of connectors is billed based on throughput ($/GB) and a task base price ($/task/hour).
- Process: Use of stream processing with Confluent Cloud for Apache Flink is calculated based on CFUs ($/minute).
- Govern: Use of Stream Governance is billed based on environment ($/hour).
Confluent storage and throughput is calculated in binary gigabytes (GB), where 1 GB is 2^30 bytes. This unit of measurement is also known as a gibibyte (GiB). Please also note that all prices are stated in United States Dollars unless specifically stated otherwise.
All billing computations are conducted in Coordinated Universal Time (UTC).
Prices vary by cloud region. Learn more about Confluent Cloud Billing.
How can I get Confluent discounts?
Confluent offers volume discounts based on usage. Please contact us or your Confluent account team for more details.
What are annual commitments?
Confluent Cloud offers the ability to make an annual commitment to a minimum amount of spend. This commitment gives you access to discounts and provides the flexibility to use this commitment across the entire Confluent Cloud stack, including any Kafka cluster type, Connect, Flink, Stream Governance, and Support. With self-serve provisioning and expansion, you have the freedom to consume only what you need from a commitment at any point in time. For more information about annual commitments, contact us.
