The SQL Server database was migrated to an Amazon RDS database connected to a VPC located in a private subnet. The Java application that was previously hosted on-premise has now been relocated to an Amazon Lambda function.

What is the recommended method for connecting an AWS Lambda function to its RDS instance?

Lambda layers can be utilized to establish separate connections to the internet and RDS.

Lambda can be configured to connect to a public subnet to access the internet, while using a Security Group to access RDS located in a private subnet.

The RDS connection string can be passed in using Environment variables.

Lambda can be configured to connect to a VPC with a private subnet and Security Group that allows access to RDS.

Can you make a prediction? Please scroll below for the answer.

Correct: 4.

Correct option

It is possible to configure a Lambda function to connect to private subnets within a virtual private cloud (VPC) in your account, along with the necessary security group to access RDS. Amazon Virtual Private Cloud (Amazon VPC) enables the creation of a private network to host resources like databases, cache instances, or internal services. Connecting your lambda function to the VPC allows access to private resources during execution. When a function is linked to a VPC, Lambda generates an elastic network interface for each security group and subnet combination in the function's VPC configuration. Here is the correct method for granting RDS access to Lambda.

Incorrect options

Lambda layers can be utilized to connect to the internet and RDS separately by configuring the Lambda function to incorporate additional code and content through the layers. A layer is a compressed file in the ZIP format that encompasses libraries, a custom runtime, or other dependencies. Choosing layers for configuring access to an RDS instance is incorrect as it will not be effective.

The statement regarding configuring lambda to connect to the public subnet for internet access and using the Security Group to access RDS within the private subnet is incorrect. Connecting a Lambda function to a public subnet does not guarantee internet connectivity or a public IP address. In order for your function to have internet access, the VPC it's associated with must have a NAT gateway or NAT instance in a public subnet.

Environment variables can be utilized to securely store secrets and modify a function's behavior without requiring code updates, including for passing in the RDS connection string. Although environment variables can be used to transfer data with RDS, access to RDS is still required and cannot be obtained solely through environment variables.

The course is updated regularly, and all questions are scenario-based, just like the real exam. The practice tests cover difficulty levels, much like the actual exam. Each question has a detailed explanation, and there is support from instructors if you have questions. The course is also mobile-compatible with the Udemy app, and there is a 30-day money-back guarantee if you're not satisfied. Trust the process and prepare to cross the winning line with absolute confidence.
