AWS Auto Scaling Groups
AWS Auto Scaling Groups is an Amazon Web Services (AWS) feature that automatically adjusts the number of Amazon EC2 instances in a group based on defined policies, such as CPU utilization or network traffic. It ensures application availability and performance by scaling out (adding instances) during high demand and scaling in (removing instances) during low demand. This service integrates with other AWS services like Elastic Load Balancing and CloudWatch for monitoring and traffic distribution.
Developers should use AWS Auto Scaling Groups to build scalable and resilient applications in the cloud, especially for web services, APIs, or microservices with variable workloads. It is essential for handling traffic spikes, maintaining high availability during failures, and optimizing costs by automatically adjusting resources to match demand, reducing the need for manual intervention.
