  • Auto Scaling: This service dynamically adjusts the number of instances according to the demand. To implement Auto Scaling in your Django app, start by creating a launch configuration specifying the EC2 instance details. Then, define an Auto Scaling group that outlines the minimum and maximum number of instances. AWS automatically scales the instances based on predefined criteria such as CPU utilization.

    import boto3

#Initialize the Auto Scaling client
autoscaling_client = boto3.client('autoscaling')

#Create an Auto Scaling group
autoscaling_client.create_auto_scaling_group( 
    AutoScalingGroupName='yourGroupName', 
    LaunchConfigurationName='yourLaunchConfigName', 
    MinSize=1, 
    MaxSize=10, 
    DesiredCapacity=5 
)

  • Elastic Load Balancer (ELB): ELB distributes incoming application or network traffic across multiple targets, such as EC2 instances, in different Availability Zones. This increases the fault tolerance of your application. Setting up ELB involves defining target groups, listeners, and health checks to ensure traffic is only directed to healthy instances.

By effectively utilizing these services, you can ensure that your Django application remains responsive and available, even during peak traffic periods.
