Managed Service for Apache Kafka® pricing policy

In this section, you can find the Managed Service for Apache Kafka® pricing policy and effective prices for its resources.

The prices for service products are also available in the price list.

All prices below do not include VAT.

Cluster statusCluster status

The prices apply differently depending on the cluster status:

• For a Running cluster, you pay for both the computing resources and storage size.
• For a Stopped cluster, you only pay for your storage size.

What goes into the cost of using Managed Service for Apache Kafka®What goes into the cost of using Managed Service for Apache Kafka®

The Managed Service for Apache Kafka® usage cost includes:

• Disk type and storage size.

• Computing resources allocated to cluster hosts (including ZooKeeper hosts) and the type of hosts.

• Egress traffic from Yandex Cloud to the internet.

In all calculations: 1 GB = 2³⁰ bytes, 1 MB = 2²⁰ bytes.

Using cluster hostsUsing cluster hosts

The host operation cost is charged per hour based on what computing resources you allocate for it. You can find the supported resource configurations in the Host classes section. For the vCPU and RAM prices, see Prices.

You can choose the host class for Apache Kafka® broker hosts, ZooKeeper and KRaft hosts based on the expected replication load. Adding ZooKeeper or KRaft hosts depends on the cluster configuration:

• ZooKeeper hosts are added to the cluster if it contains more than one Apache Kafka® host and uses ZooKeeper as the coordination service.
• ZooKeeper hosts are not added to the cluster if it contains a broker host.
• KRaft hosts are added to the cluster if its Apache Kafka® version is 3.6 or higher and if it contains more than one Apache Kafka® host and uses KRaft as the coordination service (on separate hosts).
• KRaft hosts are not added to the cluster if its Apache Kafka® version is 3.6 or higher and if it uses KRaft as the coordination service (combined mode).

The minimum billing unit is one minute, e.g., 1.5 minutes of host operation cost the same as two minutes. You do not pay for the time when a broker host, ZooKeeper, or KRaft is unable to perform its main functions.

Disk space usageDisk space usage

You pay for the storage allocated for DB clusters.

• You can only order local SSD storage (local-ssd) for clusters with three or more broker hosts:
  • For Intel Cascade Lake: In increments of 100 GB.
  • For Intel Ice Lake: In increments of 368 GB.
• You can only order non-replicated SSD storage (network-ssd-nonreplicated) for clusters with three or more broker hosts in increments of 93 GB.

The price covers one month of use based on 720 hours per month. The minimum billing unit is 1 GB per minute; e.g., storing 1 GB for 1.5 minutes costs the same as for 2 minutes.

Example of cluster cost calculationExample of cluster cost calculation

Let's calculate the cost of using a cluster with the following properties for 30 days:

• Apache Kafka® broker hosts: Three s3-c2-m8 hosts, Intel Ice Lake, 2 × 100% vCPU, 8 GB RAM.
• Storage for Apache Kafka® broker hosts: 100 GB of network HDD storage per broker host.
• ZooKeeper hosts (created automatically): Three b3-c1-m4 hosts, Intel Ice Lake, 2 × 50% vCPU, 4 GB RAM.
• Storage for ZooKeeper hosts: 10 GB of network SSD storage per host.

Cost calculation for Apache Kafka® broker hosts:

3 × (2 × $0.0136 + 8 × $0.0036) = $0.1680

Total: $0.1680: Cost of operation of Apache Kafka® broker hosts per hour.

Where:

• 3: Number of Apache Kafka® broker hosts.
• 2: Number of vCPUs.
• $0.0136: Cost of using 100% vCPU per hour.
• 8: Amount of RAM per host (in GB).
• $0.0036: Cost of using 1 GB of RAM at 100% vCPU per hour.

Calculating the cost of storage for Apache Kafka® broker hosts:

3 × 100 × $0.0288 = $8.64

Total: $8.64, cost of storage for Apache Kafka® broker hosts.

Where:

• 3: Number of Apache Kafka® broker hosts.
• 100: Amount of network HDD storage (in GB).
• $0.0288: Cost of using 1 GB of network HDD storage per month.

Cost calculation for ZooKeeper hosts:

3 × (2 × $0.0063 + 4 × $0.0025) = $0.0678

Total: $0.0678: Cost of operation of ZooKeeper hosts per hour.

Where:

• 3: Number of ZooKeeper hosts.
• 2: Number of vCPUs.
• $0.0063: Cost of using 50% vCPU per hour.
• 4: Amount of RAM per host (in GB).
• $0.0025: Cost of using 1 GB of RAM at 50% vCPU per hour.

Calculating the cost of storage for ZooKeeper hosts:

3 × 10 × $0.1171 = $3.51

Total: $3.51, cost of storage for ZooKeeper hosts.

Where:

• 3: Number of ZooKeeper hosts.
• 10: Amount of SSD network storage (in GB).
• $0.1171: Cost of using 1 GB of network SSD storage per month.

Total cost calculation:

720 × ($0.1680 + $0.0678) + $8.64 + $3.51 = $181.93

Total: $181.93, cost of using the cluster for 30 days.

Where:

• 720: Number of hours in 30 days.
• $0.1680: Cost of operation of Apache Kafka® broker hosts per hour.
• $0.0678: Cost of operation of ZooKeeper hosts per hour.
• $8.64: Cost of storage for Apache Kafka® broker hosts.
• $3.51: Cost of storage for ZooKeeper hosts.

Discount for committed volume of services (CVoS)Discount for committed volume of services (CVoS)

You can get a guaranteed discount on service resource usage when you plan for 6 or 12 months ahead. To view the resources eligible for this discount:

1. Navigate to Yandex Cloud Billing.
2. Click the billing account.
3. Select Committed volume in the left-hand menu.

A CVoS guarantees a discount on usage, but does not guarantee the availability of the resources you order. You can read more about CVoS in the relevant Yandex Cloud Billing article.

Managed Service for Apache Kafka® provides two types of CVoS: on vCPUs and on RAM for the hosts you intend to use in your DB clusters. In the management console, you can see how much you can potentially save with CVoS at the current consumption level. You can also estimate your monthly payments for the required number of vCPUs and RAM.

Prices for the Russia regionPrices for the Russia region

The monthly prices are based on 720 hours per month.

You cannot order ZooKeeper host resources via CVoS.

Outgoing trafficOutgoing traffic

When using the service, you pay for traffic from Yandex Cloud to the internet. Traffic between internal IP addresses of Yandex Cloud services and incoming internet traffic is free.

The first 100 GB of outgoing traffic per month are free of charge.

The minimum billing unit is 1 MB.
