我们可以将私有 su.net lambda 连接到公共 su.net 中的资源吗？

Question

I am connecting different AWS sources (RDS, Elasticache, EFS) in my lambda function. My AWS resources are configured in public su.nets including my Lambda function. My Lambda also needs to access the inte.net but when we configure the lambda function in a public su.net typically it can't get access to the inte.net.

Now I am thinking to shift my lambda function to a private su.net so, it can access the inte.net using a NAT gateway. My only concern is, would our lambda function (in the private su.net) be able to access other AWS resources (RDS, Elastichche, EFS) that are in the public su.net?

Or there is any other good approach that suits my scenario? One more thing, I can't move my (RDS, Elasticache, and EFS) to a private su.net.

Answer 1

would our lambda function (in the private su.net) be able to access other AWS resources (RDS, Elastichche, EFS) that are in the public su.net?

Yes, if they are in the save VPC. So that's how it is usually done. Lambda in a private vpc able to connect inte.net through NAT. Since other resources are in the save VPC (or peered), lambda will use private IP addresses to connect to them.
