What is SD-WAN and why do you need it? Quick Explainer Video

[Music] everybody my name's drew shulkie I'm the vice president of product management and deli MCS networking business unit and we're here today to do a whiteboard session on the topic of why software-defined weighing or SD win for short so the goal here today is to really frame up your knowledge and understand why SD win is such an important conversation point for our customers today and why it's an integral component of our broader multi cloud and hybrid cloud strategy at Dell EMC so to begin this journey we're gonna actually going to step back in time a little bit and think about how wide area networks have evolved over the past couple decades so let's begin with an example where we have a remote office for a large company or organization and we're in the year 2003 so I have my happy employee there and we need to think about what that employee is doing on a day to day basis in terms of the type of applications he or she is using so back in 2003 you probably were spending a lot of time in solutions like email probably had some sort of ERP system either you're doing financials or HR and so forth within a single ERP system and then you've probably had some custom applications that were unique to your firm now it's interesting as we think about in 2003 each one of those applications in terms of architectural e where they actually ran on infrastructure they were all heavily dependent upon infrastructure that sat inside some kind of centralized data center so in the case of email you probably had a Microsoft Exchange server in the case of ERP that been a mainframe Oran client server maybe an another dedicated server for that and your custom apps probably ran on a bunch of bare metal servers in that data center and so what that meant is for my employee in that remote office to be effective and productive I needed a very solid connection between that remote office and that data center and by the way that's not the only remote office in this firm I have others out there as well and they also need very reliable connections into this data center the way this was accomplished back in 2003 was I would typically use what we call a dedicated MPLS circuit what you need to know about MPLS circuits is the following one they're very reliable you purchase one of these from a service provider there's a certain level of uptime that you're actually contractually guaranteed to get they have great quality so I can do things like voice and video over them without worrying about any degradation in terms of the quality of those as deliverables but they're also relatively expensive in terms of the dollar per bandwidth but because they're so reliable and because the quality is so high and because I just need a few of these to get to my centralized data center it's still a very good approach so that's one component of the wide area network back in in 2003 the other piece was that in each one of these remote offices I would have a dedicated piece of hardware as well as one within my data center on the router so what you need about routers is they tend to be based upon proprietary technology very very expensive and you manage them on a box by box basis so this is kind of how I set up my wide area network to connect I wrote offices but not everything ran in the data center here sometimes I needed to pass traffic outside the data center and so I would bring everything through the data center because the center was a way for me to consolidate things like security so I could make I could use it as my single point of entry into my corporation and then that includes access into anything out there that you know we might just call the cloud today but back then in the 2003 we probably refer to it as the Internet and this is what a wide area network looked like in 2003 now let's fast-forward to 2019 you know I've got a similar employee now in this remote office and let's think about the type of applications that he or she is using on a daily basis now well I'm still using email I'm still using ERP I'm still using custom apps but I'm also probably spending a lot more time on things like social media and a number of other I'll just call it generally SAS based applications that are become a integral part of my day to day job and if we think about how email an ERP changed here's what I mean well email in the 2003 he was running on a dedicated server in my data center now I might be using something like office 365 which is a cloud-based email solution for ERP maybe ERP is still in my data center or maybe I've taken components of my ERP like my HR system and I've shifted it to something like workday or salesforce.com again cloud based or SAS based applications that are primarily running from the cloud and if I think about my custom apps I might still have a server farm in my data center where a lot of these run on virtual machines but a great many of them also may be sitting on things like AWS or Asher so a lot has changed in terms of the infrastructure that's running my day-to-day business in 2019 from 2013 but the wide area network hasn't fundamentally evolved I'm still passing all of my traffic over these dedicated circuits which are reliable but also very costly into my data center and then going out into the cloud to access all of them in terms of where they live and breathe on a daily basis so this presents an interesting problem because these applications that are based out here also drive just huge amounts of traffic so these circuits that I purchased in the past are being taxed in terms of the amount of bandwidth and data that I'm passing them over on a day to day basis and it's only getting worse each and every day as well it's still complex to manage this man as I have to go device by device by device and so I'm looking for some operational simplicity here and this is where Software Defined way and comes into the story and why software-defined band is the customer conversation that almost every one of our customers wants to have right now so to begin with software-defined way in allows me to have central control and what I mean by that and specific to how Delhi MC is approaching a software-defined way and is we have a virtual cloud Orchestrator which allows us to look through end-to-end in the wide area network and understand all the endpoints it gets to access to all the endpoints by accessing x86 devices that have now replaced these routers at all of these remote locations as well as in the data center a standards-based Hardware piece of infrastructure that we at Delhi MCA know very very well very cost efficient as well and what Software Defined when does is through this centralized orchestration gives me access to all these endpoints giving meet end-to-end visibility of the entire wide area network in addition there are also virtual cloud gateways out at each one of these major public cloud providers SAS applications and so forth and to be specific a couple of thousand of those throughout the global network that we know you know here at at this point in time on planet earth and what we can do with that is start to get an end-to-end view of the network and think about more efficient ways that we can start to pass traffic as opposed to these very expensive and dedicated MPLS circuits one way to go do that is to take advantage of broadband and this is the same broadband that you're probably familiar with in terms of what's running in your house today in terms of how you're actually getting Internet service into your house contrasting it with MPLS you know reliability is lower quality is lower but the cost per bandwidth is also significantly lower orders of magnitude lower and so what I can start to do through this centralized place where I can set policy my wide area network it's think about the priority of my applications what do I want to continue to run on the dedicated MPLS circuits because it's important that I maintain a level of reliability and quality and what can I start to shift to run over much more cost-effective broadband solutions and this is compelling because the economics between those two are pretty significant and so if we were to just do by an example here to give you a sense and I won't use absolute numbers because it varies by region and so forth but if I'm running a 100% MPLS circuit today and let's say this is this is my cost level right here if I can move to a model where I can get to 50 percent MPLS and 50 percent broadband I can cut my cost to about 50 percent of what it was over here now this still allows me to maintain certain critical apps running over that MPLS circuit but I'm doing it just on a smaller pipe with less bandwidth required eventually the goal for a great many of our customers is to get to a 100 percent broadband and if you can accomplish that you're getting down to about 25 percent of the transport cost that you're spending today now these are real expenses for our customers they're driving a lot of their operating cost and this is one of the key reasons why it's so compelling and so many of our customers want to have this conversation today so we kind of covered this how do I get to this 50/50 mix how do I get to this 100% broadband if the reliability and quality is so important on these dedicated MPLS circuits well here's why and here's where the great beauty of software-defined when comes into play is that I can start to utilize multiple broadband connections and through the ability through a centralized orchestration and policy engine and deep visibility into the performance the latency the jitter and things like that on each of the paths that I can direct my traffic over I can start to shoot choose the optimal path for all of my data on my wide area network over broadband guaranteeing that I have the level of quality and service that I've become used to an expecting of MPLS circuits now that's a journey our customers begin even we as Dell IT are on this journey as well where we're starting to implement this over time but this is the end state that a great many customers are going to desire but the great thing about Sdn is we can transition them into that end state by providing the ability to offload this and move the applications in a measured way in a safe way without impacting any of the performance so I hope this comes together and makes sense in terms of answering that question of why as dewayne very compelling economics the fundamental nature of the applications and where they run in our day-to-day lives as companies and organizations have changed and we need to evolve our wide area networks to accomplish that software-defined LAN is absolutely the best way to go about that as well I hope it came through we didn't talk about it explicitly but when we think about the multi cloud and hybrid cloud journey which will be on Prem which will be off Prem and constantly evolving and shifting around you need a very flexible and software-defined solution such as software-defined when to enable that so between those two pieces this is why SD Wham it's a customer conversation that you absolutely should initiate it's very well received in the time I hope you found this useful make free time [Music]
