The Amazon cloud version requires that the user has an Amazon Web Services account. New users can get more information from our AWS Account Creation guide.
Essentia is available as an Amazon Machine Image (AMI) which contains a Linux based OS with Essentia installed. Any AWS user can launch this AMI to create a private, AWS account specific master node. Prices range from $0.07-$2.00 per hour depending on instance type used, although the t2.micro instance type is free for AWS users interested in simply evaluating the software.
Go to your AWS console, where all services are listed.
Click on EC2.
Click on the ‘Launch Instance’ button. This will take you to a site where you can select what OS and software you would like to access.
Select the ‘Marketplace’ tab, and search for ‘AuriQ’
The list of results should include the latest release of Essentia. Currently this is “Essentia (HVM)” version 3.2.0. Click on it to start.
You will be asked to select a node type. For most users,
m3.medium is the safest choice, but the
t2 line is OK for
testing or other work that does not require high performance.
The t2.micro is free if you qualify for the AWS Free Tier.
Amazon will now ask you to ‘Configure Instance Details’. Use the list below as a guide:
Number of instances = 1
Network: Select VPC and choose one of your available VPCs.
Subnet: Select a subnet to launch in.
There is no strict requirement on what VPC to launch Essentia in, with one exception: users wanting to use the Redshift integrator should launch Essentia into the same VPC as their Redshift cluster.
Auto-assign Public IP: ENABLE
IAM Role: In order to utilize Essentia’s scalability you must attach an IAM role that authorizes the instance to spin up more ec2 instances (worker nodes) to aid in processing. For more information, refer to our section on IAM Roles. If you do not need to use this scalability, None is OK.
Once the instance is launched, you can connect to the web based UI by entering the IP address into your web browser. The default account username is “essentia” and password is your ‘Instance ID’. Instructions for getting started with the viewer are found in Getting Started.
Note: Always check your version of Essentia by running
