A company is planning to implement a private cloud infrastructure. Which of the following recommendations will support the move to a cloud infrastructure?
A.
Implement software-defined networking (SDN) to provide the ability to apply high-level policies to shape and reorder network traffic based on users, devices and applications.
B.
Implement a virtual local area network (VLAN) for each department and create a separate subnet for each VLAN.
C.
Implement software-defined networking (SDN) to provide the ability for the network infrastructure to be integrated with the control and data planes.
D.
Implement a virtual local area network (VLAN) to logically separate the local area network (LAN) from the physical switches.
Answer C) Implement software-defined networking (SDN) to provide the ability for the network infrastructure to be integrated with the control and data planes.
Option A is what SDN can do for you....but that answer doesn't help you move toward it. Whereas Option C helps you connect to your existing local network so that you can then migrate your assets to the cloud.
Many of today's services and applications, especially when they involve the cloud, could not function without SDN. SDN allows data to move easily between distributed locations, which is critical for cloud applications. Additionally, SDN supports moving workloads around a network quickly.
The recommendation that will support the move to a private cloud infrastructure is:
A. Implement software-defined networking (SDN) to provide the ability to apply high-level policies to shape and reorder network traffic based on users, devices, and applications.
I go with C
Implementing SDN to provide the ability to apply high-level policies to shape and reorder network traffic based on users, devices, and applications is a good recommendation for improving network performance and security but it does not necessarily support the move to a private cloud infrastructure as effectively as option C which focuses on the use of SDN to integrate the network infrastructure with the control and data planes in a cloud environment. This provides greater flexibility and control over the network, enabling automated provisioning and orchestration of network resources to support dynamic workloads and elastic scaling, which are key characteristics of a private cloud infrastructure.
Cloud Network Virtualization: Benefits of SDN over VLAN
- Prefer SDN when available.
-Use SDN capabilities for multiple virtual networks and multiple cloud accounts/segments to increase network isolation.
- Separate accounts and virtual networks dramatically limit blast radius compared to traditional data centers.
- Implement default deny with cloud firewalls.
- Apply cloud firewalls on a per-workload basis as opposed to a per-network basis.
- Always restrict traffic between workloads in the same virtual subnet using a cloud firewall (security group) policy whenever possible.
- Minimize dependency on virtual appliances that restrict elasticity or cause performance bottlenecks.
