I have a question because I am a little confused and I’m sure that others are just as confused as I am.

AWS has two separate products: 1) ALB for Application-Load-Balancing and 2) API Gateway.

These two products have some resemblance, not totally but some to the extent that network requests are taken as input and forwarded somewhere based on some internal logic.

My question is simple: We know that Kong is an API Gateway. Can Kong do ALB – Application Load Balancing also?

Any comments on the separation (or lack thereof) of these two functionalities would be appreciated.

You may also use other load-balancing products with Kong, such as Amazon’s. We do also support `proxy_protocol` in case you need that when using external load balancers.

I use “kong.response.exit(res.status, res.body)”

but when res.status!=200,have questions  
questions is No ‘Access-Control-Allow-Origin’ header is present on the requested resource.

Did I configure it right？
