Apache Kafka® host classes
Written by
Updated at October 14, 2024
The host class determines the computing power allocated for each host in a cluster. When you change the host class for a cluster, all existing hosts change to match it.
The host class also determines which disk types are available:
- s1, m1:
local-ssd
- s2, m2, s3, m3:
network-ssd
,network-hdd
,local-ssd
,network-ssd-nonreplicated
- b2, b3:
network-ssd
,network-hdd
The available storage size does not depend on the host class. For storage limitations, see Quotas and limits.
Available host classes
Hosts in Managed Service for Apache Kafka® clusters are deployed on Yandex Compute Cloud VMs. You can create these VMs on any platforms Compute Cloud supports. To learn more about the platforms, see Platforms.
The full list of possible host configurations on each platform is provided below.
Note
Not available for clusters with hosts residing in the ru-central1-d
availability zone:
- Intel Broadwell platform
- Local SSD storage if using Intel Cascade Lake
Configuration types:
- s2, s3: Standard configurations with 4:1 RAM GB to vCPU ratio.
- m2, m3: Configurations with an increased RAM GB to vCPU ratio (8:1). These configurations may be useful for clusters with higher cache requirements.
- b2, b3: Configurations with a guaranteed vCPU share under 100%. This host class is intended for test load, while the minimum recommended host configuration for production solutions is two vCPUs with a guaranteed share of 50%.
