To launch an instance

1. If you are using SOAP, construct the following request:

   <RunInstances xmlns="http://ec2.amazonaws.com/doc/2009-10-31/">
      <imageId>ami-id</imageId>
      <minCount>1</minCount>
      <maxCount>1</maxCount>
      <keyName>keypair-name</keyName>
      <groupSet/>
      <monitoring>enabled</monitoring>
   </RunInstances>

2. If you are using Query, construct the following request:

   https://ec2.amazonaws.com/
   ?Action=RunInstances
   &ImageId=ami-id
   &MaxCount=1
   &MinCount=1
   &KeyName=keypair-name
   &Monitoring.Enabled
   &...auth parameters...
   

3. View output similar to the following:

   <RunInstancesResponse xmlns="http://ec2.amazonaws.com/doc/2009-10-31/">
     <reservationId>r-47a5402e</reservationId>
     <ownerId>AIDADH4IGTRXXKCD</ownerId>
     <groupSet>
       <item>
         <groupId>default</groupId>
       </item>
     </groupSet>
     <instancesSet>
       <item>
         <instanceId>i-2ba64342</instanceId>
         <imageId>ami-60a54009</imageId>
         <instanceState>
           <code>0</code>
           <name>pending</name>
         </instanceState>
         <privateDnsName></privateDnsName>
         <dnsName></dnsName>
         <keyName>example-key-name</keyName>
         <amiLaunchIndex>0</amiLaunchIndex>
         <instanceType>m1.small</instanceType>
         <launchTime>2007-08-07T11:51:50.000Z</launchTime>
         <placement>
           <availabilityZone>us-east-1b</availabilityZone>
         </placement>
         <monitoring>
           <enabled>true</enabled>
         </monitoring>
       </item>
     </instancesSet>
   </RunInstancesResponse>
