title: Setting up mysql DB for Amazon EC2
body: <p>We are new to the AWS and would really appreciate some help and guidance.</p>
  
  <ol>
  <li><p>What is the RDS maintenance window/Back up window mean? 
  Our concern is: During the time range, our web server(@EC2) cannot access our RDS instance?</p></li>
  <li><p>What is the best practice to set up mysql for EC2 instance?
  Is it stupid to set up mysql @EC2 instance with attached Provisioned IOPS( 10 GB/100 IOPS)? :)</p>
  
  <p>Our main concern is the performance. We know we should test it by ourselves. But it is also appreciated if someone could share experiences regarding how to set up mysql for EC2 instance.</p></li>
  <li><p>What is EBS volume? Is it the Provisioned IOPS type when I click 'Create Volume'?</p></li>
