Isolating and Decoupling Legacy System through Data Hubs
The first time you create a hub, you actually make the job a little harder, which makes it difficult to gain support for this approach.

Isolating and Decoupling Legacy System through Data Hubs
Direct Connection Replace direct link between house #1 and #3 Replace
direct link between house #2 and #5 All directs link removed.

Isolating and Decoupling Legacy System through Data Hubs
Since we have to rewrite the links anyway, we just write ht links to the hub instead of
to each other.

Isolating and Decoupling Legacy System through Data Hubs
Legacy system change into directly connected architecture by eliminating,
simplifying and replacing.
