EC2 Instances

To
launch a new instance click on the launch instance button. This will open a
wizard where you can select the Amazon machine image (AMI) with which you want
to launch the instance. You can also create their own AMIs with custom
applications, libraries and data.
Instances can be launched with a variety of operating systems.
•
Instance
Sizes
•
When
you launch an instance you specify the instance type (micro, small, medium,
large, extra-large, etc.), the number of instances to launch based on the
selected AMI and availability zones for the instances.
•
Key-pairs
•
When
launching a new instance, the user selects a key-pair from existing keypairs or
creates a new keypair for the instance. Keypairs are used to securely connect
to an instance after it launches.
•
Security
Groups

The
security groups to be associated with the instance can be selected from the
instance launch wizard. Security groups are used to open or block a specific
network port for the launched instances.
