Description

In this course, you will learn the basics of SDN and NFV. You'll become familiar with what they are at a conceptual level, and how they aim to solve both business and technical problems. We'll first look at SDN and how it differs from traditional networking, then investigate NFV and how the combination of virtualization and networking have provided us some considerable automation benefits. We'll discuss how to evaluate these technologies and how they will impact you, your organization, and the industry at large. Finally, we'll help you develop an action plan so that you can take the next steps on your SDN journey.

Introduction to SDN
Welcome to another Big Picture video series from Pluralsight. In this course we'll introduce you to Software Defined Networking. My name is Brian Eiler, and I'm here with my colleague John Hales. For this presentation we'll be introducing you to both the technical and business sides of the story, so John and I will be collaborating to bring you two perspectives on the topic. Hi, my name is John Hales. In this course we will introduce you to SDN and explain how it affects you and your company. In each module Brian and I will discuss the topics from those two perspectives. One of us will play the part of the technical expert while the other will act as a business manager asking questions about the technology. For this introductory module Brian will play the role of the technical expert, and I will be the business manager. Let's take a look at how the course will be laid out. Throughout this course John and I will help you understand not only what SDN does, but how it works and how it relates to something called Network Functions Virtualization or NFV. We'll also look at the SDN and NFV landscape talking about different vendors. And then finally we'll introduce how SDN will impact you, as well as the industry. In this lesson we will talk first about the Software Defined Data Center or SDDC, SDN, and something new called Software Defined Storage and how all of this ties together. We'll then get into the details as to why we need SDN. What are some of the problems that we're experiencing today that have led to the creation of SDN and NFV? And then at a very high level we'll answer those challenges that we've talked about.

SDN Defined
Welcome back to Software Defined Networking, The Big Picture. My name is Brian Eiler, and in this lesson I will help you define SDN. In this lesson we'll explain the SDN architecture looks like; we'll talk about the data, control, and management planes; we'll also discuss the need for a man to machine translator to translate those commands, as well as centralizing the command and control; and finally how this effects things at an economy of scale.

How Does SDN Work?
Welcome back to Software Defined Networking, The Big Picture. My name is Brian Eiler, and in this lesson John and I will discuss how SDN works. In this lesson we're going to talk about what an SDN controller is, we're going to define the traffic flows, and we're going to talk about how the SDN management and controller interfaces work, as well as the two API stacks, the northbound APIs and the southbound APIs.

NFV vs. SDN
Welcome back to Software Defined Networking, The Big Picture. My name is John Hales. In this lesson Brian and I will discuss NFV versus SDN and how they compare. We'll review what NFV is and does briefly, we'll talk about the goals and purpose of NFV, and then we'll go ahead and give you some use cases for SDN and NFV.

NFV Technologies
Hello. This is John Hales. Welcome to another lesson in SDN, The Big Picture. Today we'll be discussing in this module NFV technologies. In this lesson we'll take a look at why NFV is needed. We'll take a look at why I should care. We'll look overlays and what are they and give an analogy as to why they are useful. We'll look at some common overlays including some of the common protocols. And we'll look at NFV functionality including routers and switches, firewalls, and load balancers.

SDN/NFV Vendors
Welcome to Software Defined Networking, The Big Picture. My name is Brian Eiler, and in this lesson John and I will discuss the SDN and NFV vendors. In this lesson we're going to talk about how the ever-changing SDN scene will affect you and how you might be able to even begin categorizing some of the solutions that are out there. We'll spend some time talking about who's who in the marketplace and then also talk about the Open Source initiatives. Finally, we'll talk about certifications.

SDN's Impact on You and the Industry
Welcome back to Software Defined Networking, The Big Picture. My name is John Hales, and in this lesson Brian and I will discuss SDN's impact on you individually, as well as the industry as a whole. In this lesson we'll take a look at how does my role change? Whether you're a network admin or a security admin or maybe even a developer, what if you manage those people? We'll also look at the impact of technologies on the data center of the near future, SDN, NFV, SDS, many of which we've discussed earlier. What does that mean for my data center? And then finally we'll take a look at the relationship between SDN, NFV, and cloud computing. We'll briefly review what is cloud computing? We'll touch on the types and locations of clouds, and then we'll look at why does cloud computing really need SDN and NFV to deploy it easily?
