Elasticsearch Add-On for Heroku hardware

Use this information to better understand how Elasticsearch Add-On for Heroku instance configurations (for example azure.data.highio.l32sv2) relate to the underlying cloud provider hardware that we use when you create an Elasticsearch Add-On for Heroku deployment.

Instance configurations

Deployments use a range of virtualized hardware resources from a cloud provider, such as Amazon EC2 (AWS), Google Compute Platform (GCP) or Microsoft Azure. Instance configurations enable the products and features of the Elastic Stack to run on suitable resources that support their intended purpose. For example, if you have a logging use case that benefits from large amounts of slower but more cost-efficient storage space, you can use large spindle drives rather than more expensive SSD storage. Each instance configuration provides a combination of CPU resources, memory, and storage, all of which you can scale from small to very large.

Understanding an instance configuration name

How to read an Elasticsearch Add-On for Heroku instance configuration name, such as azure.data.highio.l32sv2:

CLOUD_PLATFORM.ELASTIC_CLOUD_INSTANCE_TYPE.HARDWARE_PROFILE.HARDWARE_TYPE
CLOUD_PLATFORM
The cloud provider the underlying hardware belongs to.
ELASTIC_CLOUD_INSTANCE_TYPE

The products or features of the Elastic Stack:

  • Elasticsearch master, ml, and data nodes
  • Kibana instances
  • Application performance monitoring (APM) server instances
  • And more …​
HARDWARE_PROFILE
Optional: The hardware characteristics, such as optimization for I/O, storage, compute, or memory.
HARDWARE_TYPE
The short name for the instance type, or a number identifying a custom machine type.

Instance configurations are an Elasticsearch Add-On for Heroku abstraction of virtualized resources from the provider, but you might recognize the underlying hardware they build on in the instance configuration name. We use instance types on AWS and Azure, and custom machine types on GCP. Elasticsearch Add-On for Heroku instance configurations are not the same AWS instance types.
