In Exchange Server 2007 and Exchange Server 2010 we have 5 Server roles and below are the functions of those 5 Server Roles
Those server roles HUB and UM are not completely removed in Exchange 2013, those Server Role components are incorporated into Mailbox and Client Access Server Roles. So the functionality of the HUB and Unified Messaging still available in Exchange Server 2013 and it didn’t go anywhere
So why Microsoft combined the Mailbox, Client Access, HUB and Unified Messaging Server Roles into two server role like Mailbox and Client Access Server Roles?
Microsoft feels that, having 5 different server roles to provide the Exchange functionality will lead to complicated deployment and to make ease of deployment by combining the server roles will ease the administrator to deploy Exchange Server 2013
Load balancing functionality for the client access server requires a Layer 7 load balancer and this will increase the cost to customers, with two server roles Exchange Server 2013 supports Layer 4 load balancers and reduces the cost
When Server roles are deployed in a separate high performance servers, most of resource on the servers are not used fully. Again this leads customers to buy more number of servers, so if only two server Roles are available, there will be reduction on the cost to the customer and the resources on the servers are fully utilized
And to provide a deployment simplicity and cost effective solution to their customers, Microsoft combined the server roles together and comes up with the two server roles in Exchange 2013
- Mailbox Server Role – Hold the Mailbox Database and Public Folder database
- Client Access Server Role – All the Clients will connect to the Client Access Server to access the Mailbox content
- Hub Transport Server Role – Used to transfer the emails within the Exchange Organization
- Unified Messaging Server Role – Provides a unified mailbox, which has the email, fax and voice mail on the same mailbox
- Edge Transport Server Role – Provide a protection using the anti-spam agent for the internal and external emails transfer
