AWS Prerequisites

All things considered, the install via AWS Marketplace should only take an hour at most. All KNIME Business Hub AWS Marketplace offerings are designed as single AMI images containing all software requirements - thus, the admin will not need to access the instance’s OS during the install process.

The person responsible for the deployment of KNIME Business Hub via the AWS marketplace should be familiar with basic AWS functionality surrounding configuring EC2 instances and should have relevant permissions to initiate said instances. For additional information on internal Business Hub administration, refer to the KNIME Business Hub Admin Guide.

If you are provisioning a Business Hub BYOL instance, you will need a license key. To obtain a license key, please contact KNIME Customer Care. If you are installing a Business Hub on AWS without the use of KNIME’s AMIs, refer to the KNIME Business Hub Installation Guide.

IAM Roles and policies

To deploy a KNIME Business Hub AMI, the user will be required to have the IAM roles/policies that allow access to launch EC2 instances and manage EBS volumes. Further rights may be needed to create security groups and VPCs if they are not already created. The application does not require the use of AWS account root privileges.

KNIME AMIs do not generate any IAM roles and policies for KNIME Business Hub nor do they grant public access to any resources. Users can generate the IAM role for the EC2 instance of KNIME Business Hub with necessary access based on their use cases (e.g. S3 access, Redshift access, …).

For more information on AWS-recommended IAM security and policy of least privilege, refer to the AWS Security Best Practices in IAM Guide.

Networking

It is assumed that a VPC with an internet gateway is configured and available. For additional information on networking requirements, refer to the Networking prerequisites section of the installation guide.

Solution Architecture

All KNIME Business Hub Marketplace offerings are composed of a Kubernetes cluster initiated and contained on a single machine in a single subnet of a VPC. Use of an elastic IP is preferred for this initial machine since it simplifies the update/upgrade procedure. For more information on how to link other compute resources to a Kubernetes cluster, refer to the Kubernetes documentation.

Keys and secrets

An SSH key for access to the KNIME Business Hub instance is created or chosen via the AWS Management Console or CLI at instance launch. The admin is responsible for managing this key as per the recommendations set within their organization.

Deployment of the solution does not require creation or management of any stored secrets.

AWS Deployment Guide

This section will go through the following processes:

  1. Provision your chosen KNIME Business Hub AMI

  2. Connect to the KNIME Business Hub Admin Console

  3. Configure the KNIME Business Hub

  4. Deploy KNIME Business Hub

  5. Connect to KNIME Business Hub

Provision your chosen KNIME Business Hub AMI

From the EC2 dashboard, click on Launch Instance. This will open the instance configuration process:

Name and Tags

Choose the desired Name you would like for your Business Hub instance and add any additional tags you would like based on your organization cloud requirements (e.g. cost center, owner, …)

For more information on tags, refer to the AWS Tagging Strategy documentation.

Application and OS Images (Amazon Machine Image)

In this section, you will choose a KNIME Business Hub AMI. First, type KNIME into the search bar and select AWS Marketplace AMIs in the filter. Decide the AMI most suitable for your needs and click Select. A dialog will appear asking you to subscribe to said AMI.

Instance Type

The default size on the AMI (m5.4xlarge) is the recommended minimum size for deployment. For more information on how to properly estimate the size needed, refer to the Hardware Requirements section of the KNIME Business Hub Installation Guide.

Key pair (login)

In this section, you will either provide an existing key pair or you can create a new key pair. This key will be used for ssh access to the machine and should be recycled according to your organization’s IT security protocols.

For additional information, please refer to the Rotating AWS KMS keys documentation.

Network settings

Here, you will configure the desired VPC and subnet for the instance. By default, the instance will create and apply a new security group with the following ports open:

  • 80 (HTTP)

  • 443 (HTTPS)

  • 22 (SSH - ADMIN USE ONLY)

  • 6443 (kubectl - ADMIN USE ONLY)

  • 8800 (KOTS Admin Console - ADMIN USE ONLY)

The default security group opens the above ports for all IPs. It is recommended the admin adjust these values to adhere with their organization’s security best practices. For more information, refer to the AWS Security Best Practices for your VPC.

Configure Storage

By default, one 512 GiB EBS volume is included as a recommended minimum. The installer can increase the size of this volume or add additional if they see fit. By default, these drives are not encrypted. All customer-created data and assets will be stored on this drive.

If a user would like to encrypt the drive, they are able to. Please refer to the Amazon EBS Encryption documentation for more information.

For more information on storage size estimations, refer to the Hardware Requirements section of the KNIME Business Hub Installation Guide.

Advanced Details

None of the advanced details are required to edit. Change these at your own discretion.

If the installer would like to disable Instance Metadata Service Version 1, the solution allows so. Under Metadata version, the installer can choose the option “V2 only (token required)”.

Summary

Choose the number of instances and select Launch Instance. This process should take at most 30 minutes.

Connecting to the KNIME Business Hub Admin Console

After you have successfully provisioned the KNIME Business Hub AMI instance, you will need to connect to the Admin Console to configure the remaining setup of the KNIME Business Hub software.

To access and login to the Business Hub admin console, you will need the following:

  • The public IP address of the instance: this will be used as the URL to connect to the Hub Console from your browser

  • The AWS Instance ID: this is used as the admin password into the Admin Console. This password can be changed later.

You can find both of these items on the EC2 instance summary page for said instance. You can select the icon next to these fields to copy their value and paste them where needed.

Screenshot below:
