What Is Vpc In Aws Lambda

The answer is to access resources in a vpc from an aws lambda function a helpful feature that was introduced by aws in early 2016.

What is vpc in aws lambda. The second approach to using aws services from a lambda in a vpc is to set up a vpc endpoint in your vpc. You might think the best way to do this is through an amazon vpc which is an essential element in any secure aws architecture. Set up a vpc endpoint for your aws service.

With this feature the aws lambda function can call the netcool api over the existing vpn connection which was established for secure administrative access. Further it can be quite expensive if you want a redundant setup. When defined to run in a vpc aws lambda function needs to create an elastic network interface.

Hence our lambda function needs to be attached to an iam role that has these basic vpc permissions. Developers and administrators use vpcs to launch resources within a dedicated private network that tightly controls access. You can configure a lambda function to connect to private subnets in a virtual private cloud vpc in your aws account.

The nat gateway approach is flexible but can be a pain if you re only using a single aws service in your lambda function. To establish a private connection between your vpc and lambda create an interface vpc endpoint. If you use amazon virtual private cloud amazon vpc to host your aws resources you can establish a connection between your vpc and lambda.

You can use this connection to invoke your lambda function without crossing the public internet. Vpc endpoints allow communication with aws services from your vpc without requiring access to the public internet. Use amazon virtual private cloud amazon vpc to create a private network for resources such as databases cache instances or internal services.
