Scheduling automatic start and stop for AWS Elastic Beanstalk environments can help optimise costs by ensuring that environments are only running during required hours. While AWS Elastic Beanstalk doesn't natively support scheduling, you can achieve this through AWS Lambda, EventBridge (formerly CloudWatch Events), and the AWS SDK. Steps to Schedule Automatic Start/Stop: 1. Define Start and Stop Actions Elastic Beanstalk environments are started and stopped by updating their environment configuration. Stopping involves changing the environment's instances to a scaled-down state (e.g., 0 instances). 2. Create AWS Lambda Functions You need two Lambda functions: Start Function: Scales the environment to a desired instance count. Stop Function: Scales the environment to 0 instances. Example Lambda Code (Python): Stop Environment 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 import boto3 def lambda_handler (e...
