title: Creation of VMS within AWS Ec2
body: <p>I am trying to design and making architecture of cloud application deployment resources in AWS cloud using EC2, S3, and RDS. Here I have a little bit of confusion about AWS infrastructure, which I am describing here.</p>
  
  <p>I already have a AWS EC2 machine - Ubuntu 16.04 LTS. Is possible to create another VMs within my Ubuntu? I mean, can I use Linux or CentOS within my EC2 Ubuntu machine? </p>
  
  <p>I am a beginner in cloud and AWS world, still exploring about AWS infrastructure.</p>
