CDW provides technology solutions for business, government, education and healthcare. In the past, the company has relied on technologies such as Microsoft Lync Server 2010 and Microsoft Exchange Server 2010. CDW recently upgraded the communications infrastructure of its software sales division with Microsoft Lync Server 2013. The company believes this upgrade will help it provide improved communications options to its employees while also offering more robust capabilities to its customers. Windows PowerShell is a great management tool for CDW because the same administrators can work on the entire Microsoft infrastructure.
