The Preferred Architecture
During my session at the recent Microsoft Exchange Conference (MEC), I revealed Microsoft’s preferred architecture (PA) for Exchange Server 2013. The PA is the Exchange Engineering Team’s prescriptive approach to what we believe is the optimum deployment architecture for Exchange 2013, and one that is very similar to what we deploy in Office 365.
The PA is designed with several business requirements in mind. For example, requirements that the architecture be able to:
- Include both high availability within the datacenter, and site resilience between datacenters
- Support multiple copies of each database, thereby allowing for quick activation
- Reduce the cost of the messaging infrastructure
- Increase availability by optimizing around failure domains and reducing complexity
