Explanation

Amazon EC2 Auto Scaling provides the following key benefits:

✅ Improved health and availability of applications

• Auto Scaling automatically replaces unhealthy instances to maintain application availability
• It ensures that the desired number of instances are running at all times
• Helps maintain application performance during traffic spikes or instance failures

✅ Optimized performance and costs

• Automatically scales the number of EC2 instances up or down based on demand
• Reduces costs by scaling down during periods of low traffic
• Maintains performance by scaling up during periods of high traffic
• Uses scaling policies to match capacity to actual workload requirements

❌ Other options are not benefits of EC2 Auto Scaling:

• Reduced network latency: This is more related to AWS services like CloudFront, Global Accelerator, or placement groups
• Automated snapshots of data: This is handled by services like Amazon EBS snapshots or AWS Backup
• Cross-Region Replication: This is typically handled by services like Amazon S3 Cross-Region Replication or Amazon RDS Read Replicas across regions

EC2 Auto Scaling primarily focuses on maintaining application availability and optimizing costs through automatic scaling of compute capacity.
