Decoupled architecture
In web content management, a decoupled architecture is one in which the back-end authoring environment is separated from the front-end publishing environment by a firewall and, at times, geographically (such as by servers being placed in two separate buildings with a secure connection).
Thus, publishing content involves transferring it from one environment to another, making it a highly secure setup, as it’s much harder for hackers to access the authoring environment when hacking the website.
