在及时本开中涉及:“蟒蛇不加以咀嚼就举吞下它们捕获的食品。在就事后,它们不可知蠕动,并且它会以它所用之克在六独月内保障睡觉的状态。”

亿级

     Then I would never talk to that person about boa constrictors, or
primeval forest, or stars. I would bring myself down to his level. I
would talk to him about bridge, and golf, and politics, and neckties.
And the grown-up would be greatly pleased to have met such a sensible
man.

      “那是顶帽子”

 

       In the book it said: “Boa constrictors swallow their prey whole,
without chewing it. After that they are not able to move , and they
sleep through the six months that they need for digestion.”

  • 搭更细分,或多数据架构师,cache架构师,分布式架构师
  • 数据库sharding遭受烦恼,最先考虑分布式数据服务
  • 多少访问需要按照工作特点细分。
  • 付出、运维、测量、调优具备有和好之专有工具。
  • 享有服务得地理多机房分布,具备IDC容灾设计。
  • 服务而降

       
由此,随后,我选了外正规,并学习了开飞机。我既飞行了装有的世界面临的组成部分,同时地理对自己而言,一贯是老大有因而之。一扫,我就足以识别出中华及亚利桑这州。如若一个人口以夜幕迷路,这样的文化是很有由此的。

10万用户级别

     In the course of this life, I have had a great many encounters with
a great many people who have been concerned with matters of consequence.
I have lived a great deal among grown-ups. I have seen them intimately,
close at hand. And that hasn’t much impoved my opinion of them .

这边更添在qcon讲演将来得及考虑成熟的一个地点,用户规模影响设计,具体是负用户数每达一个数级,许多设计得重新考虑。

     
 我之著述并无是同及帽子的图。它是同一条巨蟒在消化同样峰大象的图样。可是打老人们未可以了然她,我而创作了任何一样轴画。我勾勒了蟒蛇肚子里的情况,以便为老人们好又清晰的看出她。他们不时索要给部分事情为解释。我之画作二如泣如诉想然:

百万级

        So then I chose another profession, and learned to pilot
airplanes. I have flown a little over all parts of the world; and it is
true that geography has been very useful to me. At a glance I can
distinguish China from Arizona. If one gets lost in the night , such
knowledge is valuable.

于采取Twitter几年的时刻里,平常想新浪咋样重新好的贯彻,恰好如今多少个月也与了系工作,大部分都是工程举行,总括实践会促生更具实际价值之驳斥。因而于QCon
Beijing
2010这一次演说参考了诸多网友的视角后择了《构建而扩充博客园架构》的题材。
由当支配选题时了然来自Twitter总部有30万followers的@nk否谋面讲一个好像之题材,心中就有点紧张,最充足之顾虑就是若出口的领域再他重叠,假使他道得还深远,我便无必要班门弄斧了。后来考虑到以下多少个因或者决定继续

        I pondered deeply, then, over the adventures of the jungle. And
after some work with a colored pencil I succeeded in making my first
drawing.My Drawing Number One.It looked like this:

  • db和cache单独部署服务器,db或仍工作拓展拆分(sharding)
  • cache或选拔一致性hash扩展。
  • 前者后端依旧以一道,但是依照工作拆分,每个工作可分配不同数额之服务器

     “That is a hat”.

  • 始发侧重架构设计,有特意技术架构师
  • 用跨机房部署,前端在长途增添反向代理加速,数据库在外地机房使用slave数据库副本
  • 后端拆分出来,系统中用中远距离调用,内部用远程调用协议。

       The grow-ups’ response, this time, was to advise me to lay aside
my drawing of boa constrictors, whether from the inside or the outside,
and devote myself instead to geography, history, arithmetic and
grammar.That is why, at the age of six , I gave up what might have been
magnificent  career as a painter. I had been disheartened by the failure
of my Drawing Number One and my Drawing Number Two. Grown-ups never
understand anything by themselves, and it is tiresome for children to be
always and forever explaining things to them.

千万级

Chapter 1

  • 只服务器,前端、后端、cache、db在协同。

      I showed my masterpiece to the grow-ups, and asked them whether
 the drawing  frightened  them.

  • Twitter架构是单IDC设计,从它们递增的tweet
    id就可以看出,后来当面向@nk提问也获取了证。
  • 饱受沾沾自喜网络环境差别,单IDC及多IDC有多设计达到之两样
  • 大部分参会人士未必可以针对英文讲演有深远了然与感悟,粤语的解说得提有细节解释又酣畅淋漓。
  • Twitter对故障的容忍度很,国内集团针对劳动故障不乏先例还敏感。由此国内架构师会设想设计方案尽量简单可靠,服务需再行稳定。外国开团队再一次赞成追求在工作中应用技术立异,由此会促成架构设计理念的不在少数差异。

       My drawing was not a picture of a hat.It was a picture of boa
constrictor digesting an elephant. But since the grow-ups were not able
to understand it ,

      Whenever I met one of them who seemed to me at all clear-sighted,
I tried the experiment of showing him my Drawing Number One, which I
have always kept. I would try to find out, so, If this was a person of
ture understanding. But, whoever it was,  he, or she, would always say:

老人家们的回复,此刻,是指出我按蟒蛇的画作,无论里面或表面,相反的,全身心投入到地理、历史、算术、语法。这即使是为啥,在六秋之上,我丢弃做可能为自身成平等位画师之亮丽事业。我已经给自己的创作一样哀号与作二哀号的破产的打击失去了信念,大人们祖祖辈辈不会见因而他们协调通晓外事,对于子女等的话,平常永远为他们说事,是驱动人挺厌恶的。

第一章

 

        可是她们答复:“恐慌?为啥有人会吃同样及帽子吓到?”

   
曾经当自家六春之上,我当同样按关于原始森林的名为也《自然之真正故事》的书写被来看过一个叫人记念深远的图形。它是如出一辙长条蟒蛇在吞咽一特动物之动作的图纸。这是即时幅画的副本。

     
无论什么时候,我际遇像对己来说是爆发清判断能力的他们受到之一个,我尝试让她们出示自我的作品同声泪俱下,这是自身一向以举办的。我会努力去找到,因而,是否,一个生出确实领会之食指。可是不管何人,他要么其,都见怪不怪这样说:

                              安托万 德  圣艾克絮佩里

   
而继自永不碰面针对生人议论到蟒蛇或原始森林或零星。我会强迫自己退至外的品位。我会师和他研讨桥牌、高尔夫球、政治以及领带同时成年人会好喜欢因为碰到了一个如此精明的丁。

I made another drawing : I drew the inside of the boa constrictor,so
that the grow-ups could see it clearly. They always need to have things
explained. My Drawing Number Two looked like this:

       But they answered: “Frighten? Why should any one be frightened by
a hat?”

       
我陷入了老大特其余商量着,而后起头了“穿越丛林的奇旅”。在运用彩色铅笔举行部分工作晚,我成之写了自我的首先幅作品。我之著述一样如泣如诉。它像这样:

    Once when I was six years old I saw magnificent picture in a book
,called True Stories from Nature, about the primeval forest. It was a
picture of a boaconstrictor in the act of swallowing an animal.Here is a
copy of the drawing.

                              Antoine de Saint-Exupery

       我于堂上们映现了自身的大小说,并且精晓她们是否及时幅描绘要他们倍感心慌。

       
在自家人生的长河被,我境遇了许多止关注事情结果的口,。我生在诸多那样人中。就于头里,我都娴熟地目睹了他们。可是这并从未了多的立异自己对他们之见识。
