Microsoft Exchange allows businesses to be more productive and connected. The ability to integrate critical workflow and process-driven applications with the core messaging system in the environment simplifies needed infrastructure components and contributes to significant return on investment.
The architecture and high availability for Exchange has evolved and improved significantly over the years. Previous versions of Exchange relied heavily on Windows Clustering technologies for resiliency. Instance failures, hardware migrations and even simple tasks such as mailbox moves all resulted in service interruptions that slowed business communications and negatively impacted the KPIs of the Exchange administration teams.
Exchange 2010 and 2013 have taken advantage of many new innovations that Microsoft has developed. Database Availability Groups, Client Access Server Arrays, Shadow Redundancy and simplification of how sessions are handled have all made the platform more robust and reliable. The additional requirement for an external load balancer has also improved the high availability of the platform by leaving load balancing to a virtual or physical appliance that knows how to handle it best.
When the new features of Exchange are combined with an intelligent application-centric load balancer the deployment is far more scalable and accessible than ever before. KEMP's entire line of LoadMaster load balancers are optimized for Exchange 2010 and 2013. Included deployment guides, templates, configuration wizards and sizing tools all help to make the deployment or migration of Exchange infrastructures seamless.
