Using WebSockets with CloudFront distributions have built-in WebSocket protocol support, as long as the client and server also both support the protocol. This can be ensured by only selecting. By default, the WebSocket protocol uses port 80 for regular WebSocket connections and port 443 for WebSocket Note: The CloudFormation stack must be created in the us-east-1 AWS Region, but the user pool itself can exist in any supported Region. This is likely undesirable for any API services hosted by your CloudFront distribution. Once the roll-out succeeded, our services were accessible . A Lambda function to be deployed at the edge and assigned to the origin request event. We're sorry we let you down. To configure the single page application to handle any requests provided (i.e. multi-player gaming, and services that provide real-time data feeds like financial You can extend this solution by manually modifying the Lambda function with your own processing logic. I have a single-page-app that requires to communicate with the api from the same domain under /api/graphql path pointing to a GQL server that is not hosted in AWS. This enables you to do everything from simple HTTP request and response processing at the edge to more advanced functionality, such as website security, real-time image transformation, intelligent bot mitigation, and search engine optimization. The benefit of using a confidential app client with a secret in Amazon Cognito is that unauthenticated API operations will accept only the calls that include the secret hash for this client, and will drop calls with an invalid or missing secret. In that case, all manual changes are lost. It can also be used to implement VPNs (Virtual Private Networks) and access intranet services across firewalls.
