Running an AWS Load Balancer on Elastigroup

Introduction

 

In this tutorial, you will learn how to run your AWS Load Balancers (Classic or Application) on AWS’s EC2 Spot Instances with Elastigroup, using Elastigroup’s console. Applications running behind a load balancer tend to be great candidates for Spot instances with Elastigroup. With Spot instances on Elastigroup, you can achieve substantial cost savings (up to 90%) without compromising on performance or availability.

Prerequisites:

  1. A verified Spotinst Account.
  2. An AWS Load Balancer

 

Step 1: Open The AWS Load Balancer Creation Wizard

 

Login to the Elastigroup Console (console.spotinst.com) and navigate to the Creation Wizard by clicking on the Create button in the Elastigroups tab.

 

 

In the Creation Wizard select AWS Load Balancer:

 

 

Step 2: Import Instance Configuration

 

With Load Balancer import, you can get started quickly by importing group configuration from an existing group. Elastigroup will import instance configurations such as AMI, security groups, and VPC. For a full list of configurations imported by Elastigroup, visit our docs.

In the AWS Load Balancer window select Create an Elastigroup from an existing AWS Load Balancer. Enter the Region and Load Balancer Type of the load balancer you’d like to import, select your load balancer under Balancers and click Create.

Note: Step 2 takes the configuration of your AWS Load Balancer and uses it to create an Elastigroup. This does not affect your existing AWS Load Balancer in any way.

 

 

Once you’ve selected an ASG to import configuration from, click on ‘Create

 

Step 3: Review and Create

 

The Creation Wizard prepares a json template to launch an Elastigroup with your load balancer configuration. All that’s left to do is click Create!

 

 

Congratulations!

 

You have now learned how to create an Elastigroup from an AWS Auto Scaling Group, letting you:

  • Cut your costs by up to 80%, while maintaining high availability
  • Run Spot instances behind a load-balancer with zero overhead, the Spotinst Elastigroup platform manages your Spot infrastructure including graceful terminations and instance replacements behind the scenes.

You’re now in the Elastigroup Manager view, where you can review, manage and monitor your running Elastigroup.
