A company runs a data pipeline that uses an EC2 instance to run a custom ETL script. The pipeline is critical and must be highly available. The team wants to avoid a single point of failure. Which architecture should they implement?

Use an Auto Scaling group with a minimum of 2 EC2 instances across multiple Availability Zones

Use a larger EC2 instance type to reduce the chance of failure

Place the EC2 instance in a single Availability Zone and enable detailed monitoring

Run the ETL script on a Lambda function instead of an EC2 instance

A data pipeline runs on Amazon EC2 instances. To ensure high availability, the instances should be distributed across multiple Availability Zones. Which AWS feature enables this?

Auto Scaling group with multiple AZs
