/**
* Client for accessing AmazonEC2.  All service calls made
* using this client are blocking, and will not return until the service call
* completes.
* Amazon Elastic Compute Cloud (Amazon EC2) is a web service that
* provides resizable compute capacity in the cloud. It is designed to
* make web-scale computing easier for developers. <p>
* Amazon EC2's simple web service interface allows you to obtain and
* configure capacity with minimal friction. It provides you with
* complete control of your computing resources and lets you run on
* Amazon's proven computing environment. Amazon EC2 reduces the time
* required to obtain and boot new server instances to minutes, allowing
* you to quickly scale capacity, both up and down, as your computing
* requirements change. Amazon EC2 changes the economics of computing by
* allowing you to pay only for capacity that you actually use. Amazon
* EC2 provides developers the tools to build failure resilient
* applications and isolate themselves from common failure scenarios. <p>
* Visit <a
* href="http://aws.amazon.com/ec2/">http://aws.amazon.com/ec2/</a> for

     * instances launch. If there is insufficient capacity to launch the
     * maximum number of AMIs you request, Amazon EC2 launches as many as
     * possible to satisfy the requested maximum values. Every instance is
     * launched in a security group. If you do not specify a security group
     * at launch, the instances start in your default security group. For
     * more information on creating security groups, see CreateSecurityGroup.
     * An optional instance type can be specified. For information about
     * instance types, see Instance Types. You can provide an optional key
     * pair ID for each image in the launch request (for more information,
     * see CreateKeyPair). All instances that are created from images that
     * use this key pair will have access to the associated public key at
     * boot. You can use this key to provide secure access to an instance of
     * an image on a per-instance basis. Amazon EC2 public images use this
     * feature to provide secure access without passwords. Important:
     * Launching public images without a key pair ID will leave them
     * inaccessible. The public key material is made available to the
     * instance at boot time by placing it in the openssh_id.pub file on a
     * logical device that is exposed to the instance as /dev/sda2 (the
     * ephemeral store). The format of this file is suitable for use as an
     * entry within ~/.ssh/authorized_keys (the OpenSSH format). This can be
     * done at boot (e.g., as part of rc.local) allowing for secure access
     * without passwords. Optional user data can be provided in the launch
     * request. All instances that collectively comprise the launch request
     * have access to this data For more information, see Instance Metadata.
     * Note: If any of the AMIs have a product code attached for which the
     * user has not subscribed, the RunInstances call will fail. Important:
     * We strongly recommend using the 2.6.18 Xen stock kernel with the
     * c1.medium and c1.xlarge instances. Although the default Amazon EC2
     * kernels will work, the new kernels provide greater stability and
     * performance for these instance types. For more information about
