AWS提供了许多不同的服务和功能，以帮助满足特定的系统需求。在这个场景下，最少配置的方法可能是使用AWS Elastic Beanstalk。Elastic Beanstalk通过自动化的方式简化了应用程序的部署和扩展。以下是一个示例CloudFormation模板，演示如何在Elastic Beanstalk中部署一个Web应用程序：

Resources:
  MyInstance:
    Type: AWS::ElasticBeanstalk::Environment
    Properties:
      ApplicationName: MyApplication
      SolutionStackName: "64bit Amazon Linux 2018.03 v2.8.3 running Node.js"
      VersionLabel: v1.0.0
      OptionSettings:
        - Namespace: aws:elasticbeanstalk:environment
          OptionName: EnvironmentType
          Value: LoadBalanced
        - Namespace: aws:ec2:vpc
          OptionName: VPCId
          Value: vpc-123abc
        - Namespace: aws:ec2:vpc
          OptionName: Subnets
          Value: subnet-123abc,subnet-456def
        - Namespace: aws:ec2:vpc
          OptionName: AssociatePublicIpAddress
          Value: 'false'
        - Namespace: aws:autoscaling:launchconfiguration
          OptionName: InstanceType
          Value: t2.micro
        - Namespace: aws:autoscaling:updatepolicy:rollingupdate
          OptionName: MinInstancesInService
          Value: '1'
        - Namespace: aws:autoscaling:updatepolicy:rollingupdate
          OptionName: MaxBatchSize
          Value: '2'
        - Namespace: aws:elbv2:listener:80
          OptionName: ListenerEnabled
          Value: 'true'
        - Namespace: aws:elbv2:listener:80
          OptionName: Protocol
          Value: HTTP
        - Namespace: aws:elbv2:listener:80
          OptionName: DefaultProcess
          Value: default
        - Namespace: aws:elbv2:listener:80
          OptionName: Rules
          Value: >
            [
              {
                  "Name": "default",
                  "Priority": "1",
                  "Action": {
                      "Type": "fixed-response",
                      "StatusCode": "200",
                      "MessageBody": "Hello from AWS Elastic Beanstalk"
                  },
                  "Condition": {
                      "Field": "path-pattern",
                      "Values": ["/"]
                  }
              }
            ]
