Messaging and collaboration systems like Microsoft Exchange 2013 are perceived by most organisations as vital in effective business communication with both colleagues and customers. This session explores planning considerations from both an application and infrastructure perspective and demonstrates how to apply these concepts when designing a large scale Exchange Server 2013 deployment on AWS. In this session, you will learn from Melbourne IT's experience in designing large and highly scalable Microsoft Exchange and other application platforms on AWS, using the example of how they have designed a highly resilient Exchange 2013 capable of supporting 50GB mailboxes for 50,500 users.
