Use AWS Direct Connect for primary connectivity and configure a site-to-site VPN as a backup.

Deploy two site-to-site VPN connections with equal priority for load balancing and redundancy.

Implement two AWS Direct Connect connections in different locations for active-active redundancy.

Utilize AWS Site-to-Site VPN as the primary connection with Direct Connect as the backup.

Create a new AWS Organizations organization with all features enabled. Move existing AWS accounts into the organization.

Deploy an Amazon Cognito user pool for identity management. Link the user pool to AWS IAM Identity Center (AWS Single Sign-On).

Implement service control policies (SCPs) to enforce permissions. Integrate AWS Directory Service with the corporate directory.

Establish a new AWS Organizations organization. Configure AWS Directory Service as the primary authentication source for the organization.

Enable AWS IAM Identity Center (AWS Single Sign-On) within the organization. Integrate IAM Identity Center with the corporate directory service.

Deploy AWS IoT Core in both Regions with separate domain configurations. Use Amazon Route 53 weighted routing to distribute traffic. Migrate data to Amazon Aurora Global Database for cross-Region replication.

Configure AWS IoT Core domain configurations in each Region. Set up Amazon Route 53 latency-based routing to direct traffic to the nearest IoT endpoint. Use DynamoDB global tables to synchronize data across Regions.

Establish AWS IoT Core domain configurations in both Regions. Create an Amazon Route 53 failover routing policy with health checks monitoring each domain. Configure DynamoDB as a global table for multi-Region storage.

Implement AWS IoT Core in two Regions with domain configurations. Use Route 53 geolocation routing for IoT endpoints. Enable DynamoDB cross-Region replication using streams and Lambda functions.

Configure the ALB to integrate with the OIDC IdP for authentication. Enforce authorization rules to allow only authenticated users to access the EC2 backend services.

Implement CloudFront signed cookies for both origins. Apply a strict policy to ensure all requests to the ALB and S3 bucket are authenticated.

Deploy AWS WAF rules on the ALB to block unauthenticated requests. Use preconfigured rules to filter traffic based on authentication headers.

Enable AWS Config to monitor ALB access patterns. Use Amazon EventBridge to trigger Lambda functions that revoke access for unauthenticated users.

Create a Lambda environment variable to store the API Gateway URL. Use the standard method for the programming language to retrieve the variable.

Store the API Gateway URL in a file. Store the file in the /tmp folder. Use the SDK for the programming language to retrieve the URL.

Create a file to store the API Gateway URL. Zip the file and upload it to the Lambda layer. Use the SDK for the programming language to retrieve the URL.

Create a global variable that is outside the handler in the Lambda function to store the API Gateway URL.
