Launch Instances: Automatically spin up EC2 instances based on specific needs or schedules. Manage Instance States: Start, stop, and terminate instances programmatically. Schedule Snapshots: Automate the creation of snapshots for data backup.

import boto3

ec2 = boto3.resource('ec2')
instance = ec2.create_instances(
    ImageId='ami-12345678',
    MinCount=1,
    MaxCount=1,
    InstanceType='t2.micro',
    KeyName='your-key-pair'
)

File Uploads and Downloads: Upload files directly to S3 or download them to your server. Bucket Management: Create, list, and delete S3 buckets. Manage Access: Set up bucket policies and ACLs programmatically.

s3 = boto3.client('s3')
s3.upload_file('localfile.txt', 'mybucket', 'remote-file.txt')

Adjust Auto Scaling: Programmatically adjust the scaling policies based on observed application metrics or predictions. Health Checks: Automate health checks and replace unhealthy instances.

Deploy Lambda Functions: Update and deploy AWS Lambda code. Trigger Management: Set up triggers from S3, DynamoDB, or Kinesis.

lambda_client = boto3.client('lambda')
with open("function.zip", 'rb') as f:
    zipped_code = f.read()

lambda_client.update_function_code(
    FunctionName='MyLambdaFunction',
    ZipFile=zipped_code
)

Database Backup: Trigger snapshots or point-in-time recovery operations. Scale Database: Modify instances to scale resources as per demand.

Transcribe Audio: Use Amazon Transcribe to convert speech to text. Analyze Images and Videos: Use Amazon Rekognition for image and video analysis.

rekognition = boto3.client('rekognition')
response = rekognition.detect_labels(
    Image={'S3Object': {'Bucket': 'mybucket', 'Name': 'image.png'}}
)

Metrics Collection: Collect and track metrics, collect log files, set alarms.

Automate Responses to Metrics/Alarms: Use CloudWatch alarms to trigger automated actions.

Roles Creation: Programmatically create and manage IAM roles. Policy Management: Attach or detach policies to roles or users.
