是否可以使用 AWS Lambda 连接到外部 postgresql 数据库？

Question

I am currently using Spring-boot to access an API that is able to change data within an postgresql database hosted on my machine. I would like to upload the program to AWS Lambda and use lambda for queries. Is that possible?

Answer 1

An AWS Lambda function that is not connected to an Amazon VPC has full access to the Inte.net. So, if the database is accessible on the Inte.net, then the Lambda function would be able to access it.

If you wish to add additional security by restricting the IP address range that is allowed to access the database, you can place the Lambda function in a private su.net , then use a NAT Gateway or NAT Instance in a public su.net. Attach a static Elastic IP address to the NAT Gateway / NAT Instance and all requests from the Lambda function will come from that IP address.
