Dave Larsen, Amazon, Twitter discussed on 7 Layers
Where every episode we look at a different aspect of technology from literal wires in the ground to switches and routers and all the way up to the exploding amounts art devices around us. I'm your host. Connor craven associate studios editor at sdn central this week. We are continuing to look at how the cloud has evolved since its inception in. Just a moment. You'll hear from dave larssen spirent general manager. If you haven't listened to her last episode on cloud volition. I highly recommend going back and giving it listen before david i get going on the topic. I want to let you any longer. Please sit back and enjoy my interview with dave larsen of spirit alright listeners. I'm here aspiring general manager. Dave larsen to talk about the evolution of the cloud. Hello dave how are you. Welcome to thank you. It's great to be here with you today. So could you tell listeners. Bid about yourself and explain why you are knowledgeable about how the cloud has grown and changed overtime. Sure i'd be happy to I've been industry been in the industry now for probably twenty seven years Started out focused on the advent of switched ethernet Which is the underpinning. He's technology that the cloud depends on But lately in my career. I have Spent a lot of time on cloud architecture. I'm the general manager at spier communications for our security solutions business unit which is focused on building technology for the test and measurement assurance of security capabilities whether they exist in the cloud or whether they're ensconced in a hardware appliance sits deployed in your environment. in the end you're not secured anyone point in the chain. You're not secure so we technology all of the above. I've been in this role for about six months. Previous to this role. I was in the office of the cto. Hewlett packard enterprise while i was responsible for strategy and vision for networking data security in cloud architecture for the company. So i've had a fair amount of access Both to partner chain of folks that are developing technology. That's consumed whether it's public or private or hybrid cloud or telco for that matter and i've been in a position of vision and strategy that has allowed me to see how the stuff has been evolving so a very much enjoy than looking forward on this conversation with you have. It's pretty far-reaching. And if listeners would like to learn more about security in it they can always check the back catalogue of a seven layers because we've touched on quite a bit and going off of your experience in the cloud. What technology has supported the cloud when it was beginning and just becoming widely used by private organizations really like this question connor because you know the cloud really evolved out. Nothing omar through to nist. Nick needs in terms of large entities like amazon. That had huge. It expenditures that they needed to monetize. So cloud really evolved off of the same exact technology than enterprises use circa ten or fifteen years ago so is using industry standard Technology industry standard. Our technology industry standard storage technology. One of the interesting things about that though is that over time if they became clear at scale the big public cloud operators need to run their businesses. The things needed to evolve and change. And so we've seen a lot of things in that environment that have adopted in move. Beyond what you would typically find in an enterprise. It's all based on the same technology in many respects Was based on the x eighty six processor but more more recently has been based on arm processor or really interesting inference engines for machine learning and artificial intelligence than vector processors or something that you might see from nvidia There's a whole host of technology. That's being leveraged. I think the thing that's interesting about the public cloud and the big cloud operators is what they vowed to do to accommodate the scale that they need to operate at high magin. As the cloud has grown it has been exponential somewhat. Similar to almost a hype cycle graph. Where i guess an adoption chart would be more appropriate early adopters early majority so on where does just ramp up and up and up and up. What have the bump spin in the road though as it goes up and up for the cloud as it has evolved expanded. Yeah this is this is a this is a really important question in it. It's a intersects with a lot of my own personal experience. The probably the most critical thing in getting people to move confidently to adopting cloud architecture. Model says been the evolution of the security landscape to support that in a way that allowed businesses to operate using the public cloud within their risk expectations their regulatory regime however they are whatever compliance initiatives they are required to adhere to and one of the main things. I touched on this earlier and one of the comments that i made the real evolution had to do a scale but it had to do a scale in concert with operating an environment with multiple tenants. You know we talk about multi tenant capabilities of various infrastructure components of the it domain. But the cloud has had to do this in a way that was entirely at a different scale and it wasn't just cloud operators per se. It was anybody in the hyperscale realm so that could include an uber or twitter or an apple or other large-scale entities that are providing services content capabilities to millions of entities. And that problem was something that the enterprise regime was beginning to look at in terms of thinking of individual operational silos of an enterprise as an individual tenant but he never had to do it at the scale of millions of such entities and the cloud has quite successfully over the last decade plus been able to deliver an operating model that allows you to operate reliably and securely in a co located environment. Where you when you go into the public cloud. And he reserved instance. You don't always reserve an instance that is specifically hardware. That's dedicated to you. You might be sharing that instance competitor without even knowing it but the isolation that has been Imbued injured that architecture by the cloud developers themselves as allow to reliably operate knowing that the workloads that were running on that instance have been isolated and they are only operational for us And they are exposed to the internet to some degree. The fernande of many of the applications that runs on the cloud is exposed in the security domain near that allows access privileges to that. But the rest of the back. in cloud architectures are well isolated. Vp context That allows someone.
