How can k design a highly available and globally distributed application architecture on AWS?

 In the context of AWS, you can use a global Instance for a highly available and globally distributed application architecture by using the AWS global accelerator and AWS cloud front in combination with the other services of AWS. Here is how you can achieve this particular target:-

Import boto3
# Create AWS Global Accelerator
Global_accelerator = boto3.client(‘globalaccelerator’)
Response = global_accelerator.create_accelerator(
    Name=’my-accelerator’,
    IpAddressType=’IPV4’
)
# Create AWS Global Accelerator listener
Response = global_accelerator.create_listener(
    AcceleratorArn=response[‘Accelerator’][‘AcceleratorArn’],
    PortRanges=[
        {
            ‘FromPort’: 80,
            ‘ToPort’: 80,
        },
    ],
    Protocol=’TCP’,
)
# Create Route 53 hosted zone
Route53 = boto3.client(‘route53’)
Response = route53.create_hosted_zone(
    Name=’example.com’,
    CallerReference=’unique-reference’,
    HostedZoneConfig={
        ‘Comment’: ‘Global Application Hosted Zone’
    }
)
# Create Route 53 record set for geographic routing
Response = route53.change_resource_record_sets(
    HostedZoneId=’HOSTED_ZONE_ID’,
    ChangeBatch={
        ‘Changes’: [
            {
                ‘Action’: ‘CREATE’,
                ‘ResourceRecordSet’: {
                    ‘Name’: ‘example.com’,
                    ‘Type’: ‘A’,
                    ‘SetIdentifier’: ‘us-east-1’,
                    ‘GeoLocation’: {
                        ‘ContinentCode’: ‘NA’,
                        ‘CountryCode’: ‘US’
                    },
                    ‘AliasTarget’: {
                        ‘HostedZoneId’: ‘GLOBAL_ACCELERATOR_DNS_NAME’,
                        ‘DNSName’: ‘GLOBAL_ACCELERATOR_DNS_NAME’,
                        ‘EvaluateTargetHealth’: False
                    }
                }
            },
            # Add additional record sets for other regions
        ]
    }
)
