How can I use the terraform for deployment of AWS Lambda functions?

In the context of AWS, you can deploy the AWS Lambda functions by using the technique of terraform using its Configuration language. Here is a basic example given of how you can deploy a lambda function by using terraform:-

Provider “aws” {
  Region = “us-west-2”  # Update with your desired AWS region
}
Resource “aws_lambda_function” “example_lambda” {
  Function_name = “example_lambda_function”
  Handler       = “index.handler”
  Runtime       = “nodejs14.x”
  Filename      = “lambda_function.zip”
  Source_code_hash = filebase64sha256(“lambda_function.zip”)
  Role          = aws_iam_role.lambda_exec_role.arn
}
Resource “aws_iam_role” “lambda_exec_role” {
  Name = “lambda-exec-role”
  Assume_role_policy = jsonencode({
    “Version” : “2012-10-17”,
    “Statement” : [
      {
        “Effect” : “Allow”,
        “Principal” : {
          “Service” : “lambda.amazonaws.com”
        },
        “Action” : “sts:AssumeRole”
      }
    ]
  })
}
