Final answer:
To enable or disable VPC support for a Lambda function, you need to access the AWS Lambda service section in the AWS Management Console, choose your function, and edit the VPC settings in the 'Configuration' tab. Enabling VPC involves selecting your VPC, subnets, and security groups, whereas disabling it requires clearing these settings.
Step-by-step explanation:
To enable or disable VPC support for your AWS Lambda function, you must understand that configuring VPC support determines how your Lambda function connects to resources within your VPC. Here's a step-by-step guide:
- Navigate to the AWS Management Console.
- Go to the Lambda service section.
- Choose the function you want to modify.
- Click on the 'Configuration' tab.
- Find the 'VPC' section and click on 'Edit'.
- To enable VPC, select the VPC, subnets, and security groups you want the Lambda function to access. AWS will then set up ENIs (Elastic Network Interfaces) in the subnets you selected, which allows your Lambda function to access resources within the selected VPC.
- To disable VPC support, clear the VPC, subnets, and security groups configuration and save the changes. This will remove the function from the VPC and it will not be able to access VPC resources until VPC support is enabled once more.
Remember that changing the VPC configuration of your Lambda function can lead to downtime, as AWS needs time to provision or deprovision the ENIs. Therefore, plan changes accordingly to minimize any impact on your service's availability.
