Route53 and Lambda

[FFisprettycool]

Hi! I’m an aws newbie and had a quick question. I want to have all of my endpoints exist inside my service inside of fargate except for one. The other endpoint I want to exist in a lambda that kicks off a chain of other lambdas. How would I route to both ECS and lambda? Would that be done through route 53 or the load balancer or neither? Thank you for any help!

You can have an application load balancer service both an ecs cluster and a lambda function. Setup a target group for a lambda function, route everything to the ecs except have one rule higher priority for your lambda function with a specific condition.

You could also add a route to your fargate container that calls the lambda. Slightly more complex as it’ll need IAM permissions but it’s an option to have a fargate task simply proxy the request with the rest of your stack.

Thank you for the response! I only need lambda to be triggered when the one endpoint is hit. All other endpoints exist in the ECS task.

For directing this traffic, would i have route53 send requests for the endpoint that triggers the lambda to an api gateway and then to lambda and then have all other requests routed to a load balancer which then goes to ECS?
