Additionally, the related Java application, previously hosted on-premise, has been moved to an AWS Lambda function.Which of the following should you implement to connect the AWS Lambda function to its RDS instance?Use Lambda layers to connect to the internet and RDS separately.Configure Lambda to connect to the public subnet that will give internet access and use a Security Group to access RDS inside the private subnet.Use environment variables to pass in the RDS connection string.Configure Lambda to connect to a VPC with a private subnet and Security Group needed to access RDS.What's your guess? Scroll below for the answer.Correct Answer: 4.CORRECT OPTION:Configure Lambda to connect to a VPC with a private subnet and Security Group needed to access RDS. This approach allows your Lambda function to securely access private resources during execution. When a Lambda function is connected to a VPC, it creates an elastic network interface for each combination of the security group and subnet in your function's VPC configuration. This is the proper way to enable RDS access for your Lambda function.INCORRECT OPTIONS:Use Lambda layers to connect to the internet and RDS separately.Lambda layers are used to pull in additional code and content, such as libraries, custom runtimes, or dependencies. However, they do not provide connectivity to RDS instances, making this option incorrect.Configure Lambda to connect to the public subnet and use Security Group to access RDS inside the private subnet.Connecting a Lambda function to a public subnet does not provide internet access or a public IP address. To enable internet access, the VPC must have a NAT gateway (or NAT instance) in a public subnet. This setup will not enable the Lambda function to access RDS in a private subnet.Use environment variables to pass in the RDS connection string.Environment variables are helpful for securely storing secrets and adjusting function behavior without modifying the code. However, they do not provide connectivity to RDS.Instructor:Introducing We Learn, a passionate community of professionals dedicated to transforming the way individuals approach learning and professional growth.
