Tags are a simple first step toward making it easier to manage your own cluster of instances. To read
more about tagging Amazon EC2 resources, go to Using Tags in the Amazon EC2 User Guide for Linux
Instances.
Bringing It All Together
To bring this all together, we provide a more object-oriented approach that combines the steps we showed
in this tutorial into one easy to use class. We instantiate a class called Requests that performs these
actions. We also create a GettingStartedApp class, which has a main method where we perform the
high level function calls.
The complete source code is available for download at GitHub.
Congratulations! You've completed the Advanced Request Features tutorial for developing Spot Instance
software with the AWS SDK for Java.
