What are the benefits of front-end and back-end architecture?

Rating:

Front-end and back-end architecture provides the following advantages:

1. Front-end servers simplify the administration in a large organization consisting of many Exchange servers. This architecture enables users to use a single, consistent namespace for accessing their mailboxes when there are multiple servers. Besides, if a user wants to move his mailbox from one server to another, he need not reconfigure the client computer.



2. This architecture reduces the overhead for Secure Socket Layer (SSL). When SSL is used to make a connection, information is repeatedly encrypted and decrypted. This consumes considerable processor time and effort. As a result, server performance is adversely affected. While using front-end and back-end architecture, the task is distributed between the front-end and back-end servers. Front-end servers process the encryption and back-end servers communicate without the overhead of SSL encryption. It results in enhanced server performance.



3. Front-end and back-end server architecture creates a more secure environment by preventing external users from directly accessing the servers that contain mailbox data. A front-end server provides an additional layer of security because it does not contain user information. It can also be configured to authenticate requests before sending them to the back-end server.
