杰米·斯塔克豪斯: Let's go through an exercise of defining what contributes to success of your media-based application, where we really set up the performance and the cost as the balance. 作为一个企业, generally you're looking to minimize costs, so that's one of the business requirements. 在另一边, you're also making sure that people continue to use the application, 因此,或许, let's 说 we're a VOD platform, and we wanted to make sure that we were performing the lowest-latency streams, just because that was something that, 说, the technological implementer behind the platform wanted to achieve. Might not be the best scenario. You can make it happen, but I bet that, as a business, you had a budget in mind.

So, 使成本最小化, 提供服务, 好吧, 我们这样做, but 我们这样做 by essentially running very, 非常小的, 虚拟服务, and it's only going to cost us a magnitude of like $50 a month. 好吧, we get a bunch of feedback from everybody who's using our application, that the screens are all freezing. 我们去调查, 事实证明, 好吧, all of the streaming solution is pinning our servers at 100% CPU, and they just can't keep up. We're using a stateful protocol.

So, we throw some capital, traditionally, at the problem. We co-locate some Edge servers, we start to build out a mesh network to deliver the streams, and then we also buy up some bandwidth, to create some direct connect traffic, to keep everything snappy.

Suddenly, our content is taking off. We're hitting hundreds of thousands of viewers, 数百万观众, and we're serving it all via this stateful protocol, to achieve the low latency, meaning that our hardware bill, 或者云账单, 潜在的, is getting into the not-insignificant range.

So, we don't have the upfront cash right now, so we start looking at switching into a stateless protocol, and we determine that our users, 好吧 for the use case here, 视频点播, they could actually deal with a couple of seconds of delay from the live Edge, so we move our cost into an OpEx model, paying for the bandwidth through a CDN partner, and we start to push millions of streams through it, 希望, the revenues cover the costs, 但最重要的是, we made the decision that it worked for the end consumer.

The example that I just went through, 你知道, it could sound like any number of VOD platforms that started and then ended, and some of them have continued, 他们真的, 在核心, all wanted users to come back and continue to watch their content. They wanted them to continue to be engaged with their content.
