Professional deployment
Professional configurations are intended for medium traffic sites with concerns about site availability. There are two redundant production content delivery servers, with developers and authors working in a single content management server located in the Internal network. However, because developers and authors are working in the same environment, chances are strong that developer activity could frequently bring down the site, stopping authors from creating content. This topology is for conceptual purposes only. Please contact your Sitecore Representative for actual production requirements and licensing details.
