Microsoft built Windows Essential Business Server 2008 (EBS), an all in one server suite that consolidates the core infrastructure into a more streamlined environment for greater manageability, improved security, and more predictability so IT can be more productive and less reactive, to help midsize businesses get a great experience and high ROI. If you’re considering a server upgrade, consider this; Essential Business Server 2008 will give you all of the features and value of the upgraded server whether it’s Exchange Server or Windows Server, but you’ll also have an environment that is simpler to manage. There’re features unique to EBS 2008 such as the unified management console to view and manage the IT environment, integrated management software with System Center Essentials, out of the box remote access with Remote Web Workplace, and added security with Forefront Threat Management Gateway and Forefront Security for Exchange. It’s all set up to best practices (over 300+ pages – think of the time saved referencing those) – to reduce risk and increase predictability.
