Each service runs in its own container and needs to talk to others. For example, your web front end needs data from a backend API, which might pull from a database. Docker networking makes it seamless for these services to communicate whether they're on the same machine or across a cluster. Next, scaling. When traffic to your application grows, you might spin up additional containers to handle the load. With Docker networking, you can add or remove containers without manually reconfiguring how they communicate. Networks, like overlay networks, are perfect for this dynamic scaling. Security is another major reason Docker networking matters. By default…
