What is AWS Auto Scaling?

AWS Auto Scaling is a service provided by Amazon Web services (AWS) that consequently changes the quantity of compute resources (for example, Amazon EC2 instances, Amazon ECS undertakings, or Amazon DynamoDB tables) in response to changes in demand for your application.

Auto Scaling assists you with keeping up with application accessibility and allows you to scale your resources flawlessly to satisfy fluctuating needs while optimizing costs. Rather than manually adding or eliminating instances, Auto Scaling automatically adjusts the capacity limit in light of conditions you define, for example, central processor utilization, network traffic, or custom metrics.

Dynamic Scaling:

• Automatically adjusts the number of instances in your Auto Scaling group in response to changing demand.

Predictive Scaling:

• Uses machine learning algorithms to forecast demand and automatically adjust capacity ahead of anticipated changes.

Scheduled Scaling:

• Allows you to plan for predictable changes by defining schedules for changing the number of instances in your Auto Scaling group.

Target Tracking Scaling:

• Sets a target value for a specific metric (e.g., CPU utilization) and automatically adjusts capacity to maintain that target.

Step Scaling:

• Increases or decreases the number of instances based on a set of scaling adjustments known as “step adjustments,” which vary based on the size of the alarm breach.

Simple and Granular Scaling Policies: Define scaling policies based on your specific requirements using simple configuration options.

First, we need to know about internet traffic and how it works. Load Balancer handles the incoming internet traffic and distributes to various instances. Integrating AWS Auto Scaling with a Network Load Balancer (NLB) offers a strong solution for guaranteeing the high availability and versatility of your applications facilitated on Amazon Web services (AWS). Auto Scaling progressively changes the number of EC2 instances because of shifting traffic loads, while NLB effectively distributes incoming traffic across different multiple targets within AWS.

By integrating Auto Scaling with NLB, associations can easily deal with variances in application demand while maintaining a consistent client experience. This integration empowers programmed scaling of EC2 instances in view of predefined scaling strategies, guaranteeing that your application can deal with expanded traffic volumes without manual mediation.

In this article, i will guide you how to integrate the AWS autoscaling with the Network Load Balancer.
