标 题: Re: 知识共享：AWS和Linode没法比

 
首先，很多ISP封80端口。更不用说mail端口了。
可以说是为了安全性，还有防止用户从家里发垃圾邮件。
也可以说是不愿意用户host services。

其实，美国的基础设施属于第三世界。刮风下雨停电断网是很平常的事情。

再次，你要是每月平均上传几个TB，ISP不找你麻烦才是见了鬼。

除非你自己host一个casual blog。任何正经服务，哪怕是公司网站，用自己家host都
是不现实的。AWS $3一个月的，比这个靠谱多了。

这种事情有什么好犟的呢？让事实说话不行么？
Verizon FIOS: Block 80, 25, 22
Comcast: Block 25, 还有一堆其他的1080之类的，不重要。

停电美国基本家常便饭。我以前停电一周是很正常的，最近几年有好转。今年停了4天
网。长岛上千万的豪宅，每年停几次，每次一周，也是家常便饭。

另外，每年连停三天三夜，可靠性大于99%，你听说哪个data center有过这种事？

老顾说动态IP没有静态的，根本不是个事儿。每年才变一次，DNS一分钟就重新解析了
。那个down time，都多少个9了。比连停三天三夜好几十万条街了。

再算经济账。除非你每年都换ISP，能把价格维持在每月$50左右。否者每月不宰你$60-
$70对不起天地良心。你每月上传2TB数据试试能挺多久？Host每月$5，就是2TB，而且
只算出，不算入。这个成本郑家不到10%，也就是一个州税级别的。

关于卡脖子的问题。我不信AWS靠这个服务能值上万亿。它卡不了我的脖子。反倒是我
在故意挖资本主义的墙角。同样的价格好多家。我分分钟就能跳船。别忘了，我刚刚提
醒老顾。DNS重解析也就是一分钟的事情。

  https://killer.sh Pre Setup Once you've gained access to your terminal it might be wise to spend ~1 minute to setup your environment. You could set these: alias k = kubectl                         # will already be pre-configured export do = "--dry-run=client -o yaml"     # k get pod x $do export now = "--force --grace-period 0"   # k delete pod x $now Vim To make vim use 2 spaces for a tab edit ~/.vimrc to contain: set tabstop=2 set expandtab set shiftwidth=2 More setup suggestions are in the tips section .     Question 1 | Contexts Task weight: 1%   You have access to multiple clusters from your main terminal through kubectl contexts. Write all those context names into /opt/course/1/contexts . Next write a command to display the current context into /opt/course/1/context_default_kubectl.sh , the command should use kubectl . Finally write a second command doing the same thing into /opt/course/1/context_default_no_kubectl.sh , but without the use of k
