Launching EC2 Spot Instances with Auto Scaling and Amazon CloudWatch

EC2 auto scalling group that maintain, scale-up, or scale-down the number of instances needed based

on scaling policies that are defined based on the demands of that particular application.

EC2 allows automatically add or remove the instances as needed. Dynamic scaling responds to

changing demand and predictive scaling automatically schedules the right number of EC2 instances

based on predicted demand.

EC2 Spot Instance : spot instance allows us to request for unused EC2 instances in the lower cost.

To create the EC2 Autoscalling we need to create load balancers first.

Creating a Load balancer:

Step 1: EC2 Spot Instances

the load balancer will create requests to EC2 spot Instances.

Create Load Balancer ---> select HTTPS/HTTPs

Step 2: click on Next and then and create a new security load balancer leave it as default and click on

next.---> add configure routing.

Step 3: Register for targets ----> review and create.

Creating the launch template for the Amazon EC2 Auto Scaling Group

Step 1: Creating a launch configuration (this will create the configuration of instances that EC2 spot

wil create later if needed.)

Step 2: Navigate ot EC2--->Lauch cofiguration(scroll down)

Step 3: Choose key pair then click on Create launch configuration.

Step 4: Go to the dashboard of launch configuration and click on instance then go to action click on

create Autoscalling group.

EC2 >>Auto Scaling groups>>Create Auto Scaling group\

· Step 1 >> Choose launch template or configuration

Step 2 >> Configure settings and Select all Subnets

Click on next and enable instance scal protection.

We have Created Autoscalling group so we need to check wheather it’s working or not.

Monitor and test the Auto Scaling group

Step 1: Click on Launch Instances from Templeates select the template that we have created

myTemplate.

Step 2: Set Number of Instances that you want to run at a time after some time all instances are

running

Step 3:Click on the Details for all setup we have done then click on Management Instances

all Instances are successfully handled by Scaling groups.
