🟦 Objective 1.2 – Software-Defined Networking (SDN)
📘 Lesson 1, Topic B
Software-Defined Networking
Network architecture approach where the control plane is separated from the data plane. A centralized controller manages all network devices, allowing for more dynamic, scalable, and efficient network configuration—especially in cloud environments.
🟦 Objective 1.2 – Software-Defined Networking (SDN)
📘 Lesson 1, Topic B
Why is SDN a good fit for cloud computing?
Because cloud environments are dynamic and scalable, SDN allows fast, centralized changes to networking that match the flexibility of cloud-hosted virtual machines.
🟦 Objective 1.2 – Software-Defined Networking (SDN)
📘 Lesson 1, Topic B
What are the control plane and data plane in networking?
