What is an Enterprise SCpbMD deployment?

The Enterprise deployment builds on top of the Professional+ deployment by starting to scale out all of the services horizontally. This deployment is the base to use for all sites with heavy load requirements.

The load-balanced CM servers are used more for redundancy than load, and help ensure that the CM environment will always be available for content authors. Processing servers work by reading from an xDB queue of unprocessed data. Additional processing servers means a faster turn-around with the queue.

Be aware that the following image shows two servers in each grouping, but you can scale outwards with more servers as your demand increases.

With the increased load, there may be increased requests the AOS server. You may want to increase the number of Transaction Servers to handle the extra traffic and provide redundancy in case a server fails.
