Introduction: Auto Scaling Groups (ASG)
Learn how AWS Auto Scaling groups optimize app performance and cost by automatically adjusting EC2 instance levels based on demand.
We'll cover the following...
Auto Scaling groups (ASGs) ensure our applications are flexible, reliable, and always available in the cloud. They are essential for maintaining optimal performance, especially when facing high demand. In this lesson, we’ll learn about ASGs and explore their operations and important role in scaling our AWS-hosted applications.
What are ASGs?
Auto Scaling groups (ASGs) are an AWS service that automatically adjusts the number of EC2 instances running an application based on demand. We can consider an ASG a system that monitors our application’s traffic. When demand increases, ASGs add more instances to maintain performance. Conversely, when demand decreases, ASGs remove instances to reduce operational costs.
Here are some important points regarding ASGs:
ASGs automatically manage the collection of EC2 instances, adjusting the quantity in response to demand to ensure that the application maintains optimal performance and cost-efficiency.
ASGs can define the minimum, maximum, and the desired capacity that can be run to handle the workload, maintaining the desired capacity within this range.
ASGs primarily focus on infrastructure management, ensuring instances are available to handle the application load. ...
