Design the Network Services and Infrastructure
From Next-Generation Data Center
Finally it’s time to get our hands dirty. We’ll talk about virtual networks needed by application workloads, focus on data center fabrics, design one, and deploy network services on top of it.
The guest speakers in this module include:
As Internet IPv6 adoption is becoming more real there are practical considerations for many businesses to consider. I invited Ed Horley to give you some guidelines and describe lessons learned while deploying IPv6 within data centers, and what you need to consider before you start your IPv6 journey. He also addressed these questions:
- Should you implement IPv6 in parallel with IPv4 (dual-stack) in the data center?
- Can IPv6 deployment in a data center be an advantage for certain services, applications and workloads?
- Are there specific things to be wary of when adopting IPv6 in the data center?
- What training, skills and resources do I need to make it actually happen?
In autumn 2016 course, Russ White (LinkedIn) described the principles of disaggregation and white box switching data center solutions, the problem space and various open-source solutions, including their positive and negative attributes.
- Disaggregation versus white box versus SDN -- what is the difference
- The components of a fabric; switches, optics, network operating system, control plane
- Building the fabric: Clos designs, oversubscription, managing complexity
- Overlay options: VXLAN and EVPN
- Other topics: Service chaining and security
If you’re not familiar with virtual networking and virtual appliances, start with Introduction to Virtual Networking webinar (2 hours).
You’ll find the information you need to understand modern data center fabrics in these webinars:
- Data Center Fabrics (you might skip the vendor-specific sections at this time, the vendor-neutral part of the webinar takes ~4 hours).
- Leaf-and-Spine Fabric Architectures (7.5 hours)
- Leaf-Spine fabrics discussions from Autumn 2016 course (1 hour 15 minutes)
- Pods and superspines (15 minutes)
- Whitebox switching and disaggregation from Autumn 2016 session: Concepts and Hardware, Architectures and Challenges (~2 hours 15 minutes).
To get familiar with the principles of overlay virtual networking watch:
- Overlay Virtual Networking webinar (3.5 hours).
- Overlay Virtual Networking discussion from Autumn 2016 session and related questions (2 hours).
You should also read these Expert Express Case Studies (plan to spend approximately one hour per case study).
- Combining physical and virtual appliances
- Designing a private cloud networking infrastructure
- Redundant server-to-network connectivity
- Scale-out private cloud infrastructure
Finally, it might be worth watching IPv6-Only Data Centers webinar with Tore Anderson (~ 1 hour).
Additional recommended materials
- VXLAN Technical Deep Dive (3.5 hours)
- Virtual Firewalls (3 hours)
- VMware NSX Architecture(2.5 hours)
