At first glance, it seems clear that the cloud era has fundamentally changed the way we think about networking. We’re now operating outside defined perimeters, and networks can span multiple data centers or clouds.

Networking still needs to be based on service identity because that’s how orchestrators track things, but the shift away from static, IP-based networking toward a service-based networking solution that these service discovery features provided was perhaps the most impactful change to networking, making application identity the basis for networking policies.

Additionally, once you transition networking policies to a service-based networking solution, maintaining traditional networking technologies can actually hinder the ability to achieve consistency.

Even as networking continues to evolve, however, the core goal remains: moving away from IP-based networking to service-based networking.
