This Quick Start deploys Microsoft Exchange Server 2013 in a highly available architecture on the AWS cloud, using AWS services and best practices.The Quick Start includes two automated AWS CloudFormation templates. The main template deploys Exchange Server 2013 with Active Directory Domain Services (AD DS) in a new Amazon VPC. A separate template deploys Exchange Server 2013 into an existing Amazon VPC, for customers who have already set up AD DS.The automated AWS CloudFormation templates build the minimal infrastructure required to run Exchange Server 2013 on AWS with high availability for a small deployment that supports 250 mailboxes. The deployment guide provides guidance for two additional deployment scenarios (for 250 and 2,500 mailboxes) that support the Microsoft preferred architecture for Exchange Server. You can use any of these scenarios as a starting point for your own implementation. This documentation is offered for free here as a Kindle book, or you can read it online or in PDF format at https://aws.amazon.com/quickstart/.To install Exchange Server with other Windows servers on AWS in a single deployment, see the Quick Start for Microsoft servers at https://aws.amazon.com/quickstart/architecture/microsoft-servers/.
