VPC

When a Lambda function is connected to a VPC, the function can no longer access the internet. One way to resolve this is to use a NAT gateway, read on to see how.

In a previous post, I showed how to use a VPC Endpoint to give a Lambda function (which is connected to the VPC) access to Secrets Manager. In this post, I will show how to use a NAT Gateway to give a Lambda function access to Secrets Manager and the internet.

When a Lambda function is connected to a VPC, accessing the Secrets Manager becomes more complicated because the function no longer has internet access. One way to resolve this is to use a VPC endpoint.

Querying an RDS SQL Server from Lambda is a great option for .NET applications. In this post you see how to create all the infrastructure, seed the database, deploy a .NET 6 Web API application, and connect the VPCs.
