Deploying Apex to a Salesforce Production Organization
After you have finished all of your unit tests and verified that your Apex code is
executing properly, the final step is deploying Apex to your Salesforce production
organization.
To deploy Apex from a local project in the Force.com IDE to a Salesforce organization, use the Component Deployment Wizard. For more information, see Force.com IDE.
Also, you can deploy Apex through change sets in the Salesforce user interface.
For more information and for additional deployment options, see Deploying Apex.
