如何从内部经典负载均衡器服务的应用程序访问 AWS SNS？

Question

I have an application running in an AWS EKS cluster, the application is previously serving with a public-facing load balancer thus it can easily AWS SNS service, but due to some security reasons we are asked to move that to serve via the internal load balancer, now after moving to the internal load balancer, the application is working but was not able to access SNS service.

How can we configure the application from the internal.network to access the AWS SNS service?

In Short, as you are within a private.network, you need to create VPC Endpoints in order to access the AWS services that are outside of a VPC.
