Deploying an Amazon EKS Application Cluster

On This Page


This guide describes how to install (deploy) MLOps Platform application nodes to Amazon Elastic Kubernetes Service (Amazon EKS) in an AWS cloud — i.e., deploy an AWS EKS platform application cluster.

Configuring an EKS Application Cluster

On the Clusters page of the platform installer (Provazio), fill in the EKS related configuration parameters, and then select Next.

New EKS app cluster
Kubernetes Kind
Set this to New EKS Cluster.
Root Block Device Type
Leave this set to General Purpose SSD.
Root Block Device Size
The size of the EBS for the control plane.
SSH Key Pair Kind

The type of key pairing to use for SSH connections to the EKS application cluster:

  • New — Create a new SSH key.
  • Existing — Use an existing SSH key.
  • None — Don't use any SSH key.
    Note that when this option is set, you cannot use SSH to connect to the EKS application nodes.
SSH Whitelist CIDRs
Leave this empty.
Node Groups

You can group application nodes in the EKS application cluster into groups.

The installer predefines a default node group named "iniital". You can select the edit icon for this group to edit its configuration, but you cannot delete this group or change its minimal number of instances (1). The minimum number of instances (Min # of instances) for the default node group is currently not configurable.

EKS app cluster: default node group

You can select the plus-sign icon (+) to define one or more additional custom node groups. You must select a lifecycle type for the node group. The default is On Demand.

EKS app cluster: new node group

Configure the following parameters for either On Demand or Spot node groups.

The name of the node group.

The EC2 instance lifecycle type. Choose On Demand or Spot

On Demand—recommended for applications with workloads that cannot be interrupted

Spot—cost-effective instances which are flexible about when applications are run and if they can be interrupted

# of Instances
The number of instances (nodes) to deploy for this group.
Min # of Instances
The minimum number of nodes in the group.
For the default node group, the value of this parameter is currently not configurable. For additional groups, you can set this parameter to any positive number or to zero. For high availability, it's recommended to have a minimum of two application nodes in each group.
Max # of Instances
The maximum number of nodes in the group.

If you selected On Demand as your lifecycle type you will need to configure the size of the node group.
The EC2 instance size for the nodes in the group.

If you selected Spot as your lifecycle type, you will need to configure the parameters for each node in the group.
Min # of CPUs
The minimum number of CPUs in each node.
Max # of CPUs
The maximum number of CPUs in each node.
Min # of GPUs
The minimum number of GPUs in each node.
Max # of GPUs
The maximum number of GPUs in each node.
Min amount of memory (GB)
The minimum amount of memory (GB) in each node.
Max amount of memory (GB)
The maximum amount of memory (GB) in each node.

When you're done, proceed to Step 9 of the platform's AWS installation guide.
