Apache Kafka® host classes
Written by
Updated at April 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. See Platforms for a detailed description.
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%.
