Hello, everyone.Allow me first to apologize I do, like many of you, appreciate the comforts of everyday routine, the security of the familiar, the tranquility of repetition.I enjoy them as much as any bloke.But please, is there anything wrong with our everyday routine?I guess there is. We do something wrong again and again and again. Everyday! Our group just feel sick of what we do, we just feel sick of the fucking situation.So we choose this topic, that is, procrastination. Maybe many of you are not so familiar with this word. So let me say it in another way.It means putting off the work we should do to a later time, sometimes to the last minute.
How did this happen? Who’s to blame?Certainly no one is intentional. But if you want to find the guilty, you need just look into a mirror. Why do I say “guilty”? Well, it is just because that procrastination does have its bad effects.And this is the purpose of our choosing this topic.
It seems that if you want to give a successful report, you must explain your purpose exactly. As we all know, a good report must be close to our life. Like the love at first sight, we found the bandwagon effect. However, the seventh group chose the same topic with us. So we sought to change the situation. Then we found procrastination. Then we decided to make sure whether the topic is close to our life or not. So we begin to observe our classmates. And the result is quiet satisfactory, nearly all our classmates finish they math homework at the night before the day to hand it in, some classmates even finish their homework on the math class. The time to hand in our homework is often Monday. Before Monday there’s a weekend, but our classmates often put off doing homework again and again. As a result, they often do not have enough time. For this reason, some students even copy others’ homework.
We all know that without enough time, we can never finish our works well. Without enough time, we’ll have to walk through the problems. Without enough time, we can not master the knowledge well. Without enough time, we can never improve ourselves by doing works. So we shall never turn a blind eye to procrastination.We must face the problem and try to solve it.
So the purpose of our choosing this topic is obvious. There’s always something we shall never forget.

计算机，作为第三次工业革命中的突出产物，本来是只能单机作业的。然后网络的出现，为计算机应用提供了一个更为开阔的平台——云端。欢迎走入，云计算的前世今生。
什么是云计算
米歇尔是个地地道道的美国农场主，她靠经销水果生意谋生。而前段时间呢，她正为水果的批发配送问题感到头疼。为什么呢？因为她得自己找司机和货车来进行批发配送。这个自己管理物流啊，确实是很让人头疼的事，因为你并不知道你到底需要多少货车。比如夏天她只需要一辆货车，而到了秋天，她就得有三四辆货车了，这样一来，不仅维持常备货车的资金是个很大的负担，而且一旦物流跟不上，米歇尔就得亏本了。再说了，米歇尔是个地地道道的农场主，她只喜欢倒腾水果，不喜欢倒腾货车，这下子米歇尔啊，是真的要hold不住了。
不过现在她不再烦恼了，因为她发现了一种新的物流业务，这种物流业务可以按照需求提供车辆，并按实际使用量付费。什么意思呢？这就是说啊，夏天的时候，不是只要一辆车吗？那米歇尔就可以只付一辆车的钱，到了秋天，需求的车多了，简单，多付点钱就好了。这样一来，米歇尔不仅不需要维持常备货车，连管理都省了，这下子她就又开开心心地倒腾水果去了。
几年之后，米歇尔的生意越做越大，这下子咱们的农场主又不消停了，她不再只倒腾水果批发了，她还要办网店自己搞点零售！于是她把水果店的网站、服务器和数据库都搬到了自己家里维护。这不维护不知道，一维护吓一跳，这样一来，花销上去了，安全隐患也来了。服务器的内存老是不够，一死机了怎么拍都回不过魂来。最后让米歇尔高喊着天不弃我的，正是和按需配送的新物流方式相似的技术——云计算。
她把网站外包给云计算公司，再也不必担心网络问题。云服务安全省事，支持“云”备份和网络访问，把管理网站的事交给云，她就又可以集中精力倒腾水果了。不仅如此，无论她的生意做得多大，云计算都能应付。首先，云计算几乎可以提供无限的数据内存和服务资源，支持业务任意扩展；其次，云服务器采用多点式备份，信息更安全；最让米歇尔满意的是按实际使用量收费，如果业务减少时，支付的费用也会相应降低。
另外，云计算还向用户提供各种云端Web服务。如需更换收费系统，用户可选择在本地安装或直接通过web浏览器使用云端的系统。从收发email，文字处理到分享照片，云计算始终让我们舒舒服服。我们可以使用云端上的所有产品，包括免费备份、联机访问这些东西，安全，而且省心。云计算给我们提供了新的选择不懂技术生意照样红红火火。
