As technologists, we tend to live in a world of acronyms and terms quite common to those of us in the industry. But this abbreviated language can seem like a foreign language to those outside of it. Recently, while on a bicycle ride, a friend and I were talking technology. In our conversation, I mentioned SOA and the not so recent shift from WS to REST and JSON. I brought up some of the most current cloud announcements and how easily we can now dynamically scale applications or spin up environments. However, five minutes into my rambling the conversation he asked, “What’s SOA?” Without missing a beat I replied, “It’s a TLA”.I then stopped, not literally of course, as I would’ve caused a crash in our weekend makeshift peloton! I stopped when I quickly realized I had just committed a cardinal sin. I assumed he knew the terminology and the technology, though he isn't in the field. And admittedly, since I am passionate about technology, I'm sometimes blissfully unaware that others may not be like me. I began explaining to my friend that TLA is a bit of a joke within the IT industry because it is actually an acronym for a three letter acronym! Yes, us techies rival today's teen in making the English language as short as possible.My babbling made me think back to a recent training session I had the privilege of attending where Professor Stuart Gilson of Harvard University (a professor of Finance) explained the premise of corporate leveraged buyouts (LBO). The session was extremely informative and the delivery of his explanation was thought provoking, something I will never forget. In his lecture, he could have easily digressed into a world of financial jargon and most of us would have likely started daydreaming. However, he explained a leveraged buyout in terms of purchasing a home, which is essentially a leveraged buyout. As I looked around the room, everyone was engaged. Why? Because we all understood it, we have all experienced it and we were all on the same page.So I backtracked a bit in my conversation with my cycling friend and explained the basic acronyms. I even touched on topics such as mobile, cloud and wearable devices, all of the stuff that gets me fired up! Then I lost him again. Somewhere in the conversation I mentioned SaaS, IaaS, PaaS, etc. and again he asked “What’s aaS?” I broke down the basics of cloud computing and its associated service models by using the example of making a pizza. The premise of the “Pizza as a Service” example is quite simple and can be explained as: 1. You can make a pizza at home where you’re responsible for buying all of the ingredients including making the dough. 2. You can purchase some of the ingredients and buy pre-packaged dough. 3 You can have pizza delivered to your home. 4. You can simply load up the family and head out for pizza at your local dining establishment. In each case you’re still having pizza however in some cases you do all of the work and others you have other people do the work for you.As it turns out, the pizza example was something he could relate to and it reaffirmed that sometimes we simply have to take a step back and keep things simple. It's not a new concept, but it’s something a techie easily forgets! Thanks to Professor Gilson for helping me to remember that sometimes keeping it simple is the best way to deliver a message. Time for lunch..pizza anyone?

作为技术人员，我们倾向于生活在一个缩写词和术语的世界中，这些缩写词和术语在我们行业中非常常见。但是这种缩写的语言对于外部的人来说似乎是一种外语。最近，在骑自行车时，我和一个朋友在谈论技术。在我们的对话中，我提到了SOA，以及最近从WS到REST和JSON的转变。我提到了一些最新的云公告，以及我们现在如何轻松地动态扩展应用程序或启动环境。但是，到我漫无目的地走了五分钟对话 他问：“ SOA是什么？”我没有错过任何机会，我回答说，“这是TLA”。

然后我停了下来，而不是字面上的意思，因为我会在我们的周末临时乘员中造成撞车！当我很快意识到自己刚犯了一个主要罪行时，我停了下来。我以为他虽然不熟悉该领域，但他知道术语和技术。诚然，由于我对技术充满热情，所以有时我很幸福地没有意识到其他人可能不喜欢我。我开始向我的朋友解释说，TLA在IT行业中是个玩笑，因为它实际上是三字母缩写的缩写！是的，我们的技术人员在使英语尽可能短方面可以与当今的青少年媲美。

我的胡言乱语让我回想起最近的一次培训课程，我有幸参加了哈佛大学的Stuart Gilson教授（金融学教授）讲解企业杠杆收购（LBO）的前提。会议非常有益，他的解释令人发指，这是我永远不会忘记的事情。在他的演讲中，他本可以轻松进入金融行话世界，而我们大多数人可能已经开始做白日梦。但是，他从购买房屋的角度解释了杠杆收购，本质上是杠杆收购。当我环顾房间时，每个人都参与其中。为什么？因为我们都了解它，所以我们都经历了它，而且我们都在同一页面上。

因此，我在与单车友的谈话中回溯了一点，并解释了基本的缩写词。我什至涉及到诸如移动，云和可穿戴设备之类的话题，所有让我兴奋的东西！然后我又失去了他。在对话中的某个地方，我提到了SaaS，IaaS，PaaS等，然后他又问“什么是aaS？”，我以制作比萨饼为例介绍了云计算及其相关服务模型的基础知识。“披萨即服务”示例的前提非常简单，可以解释为：1.您可以在家里自制披萨，负责购买所有原料，包括制作面团。2.您可以购买一些原料并购买预先包装的面团。3您可以将比萨饼送到家里。4。您可以简单地负担整个家庭的负担，然后前往当地的餐饮场所享用披萨。在每种情况下，您仍然会吃披萨，但是在某些情况下，您会做所有工作，而在其他情况下，您会由其他人来为您做工作。

事实证明，披萨的例子与他有关，它重申了有时候我们只需要退后一步，保持简单。这不是一个新概念，但它是技术人员容易忘记的东西！感谢吉尔森教授帮助我记住有时保持简单是传达信息的最佳方法。午餐时间。披萨有人吗？
