I am not an AWS user but working in the area of Infrastructure As A Service (IaaS), which is the same space AWS belongs to. As an AWS end user, there is very little difference between using an AWS terminal and an on-prem terminal. For an IT professional, AWS or IaaS allows massive automation in provisioning basic infrastructure (creating, installing, and configuring servers and applications) to meet the demands in a timely fashion as required. At an enterprise level, using AWS or any IaaS service means incorporating external infrastructure into the existing on-prem enterprise infrastructure. This can be very complicated. Commons issues I have seen are in areas such as security and networking. Hope this will get you started in learning more about AWS or IaaS.

云平台有个规模效应。 主要优势有这么几个: reliability. 人家整个高科技云团队在背后服务。就算一个data center挂了,数据还能自动roll over到附近的data center。不会丢失数据。 security. 现在数据安全复杂性特别高,很多时候一个公司很难应对了。 scalability.就像你说的,能轻松自如的scale up or scale down。用句广告词就是,only pay for what you need. 此外,因为规模效应,能享受到云团队开发出来的额外功能,比如自动简单高效的机器学习之类的。 未来五年是云的。 粗浅的理解。欢迎指正。
据他说,AWS EC2的主机托管服务,从普通用户的角度来说,和on-premise server farm并没有本质的区别。 AWS当然是技术含量很高的东西,但技术是在AWS infrostructure这边。 使用AWS,其实是很简单的东西。这也正是AWS的高明之处,把复杂的实现细节都隐藏了。
AWS对于新兴企业的吸引力在于,避免了初期部署server farm的巨大开支,“按实际使用量付费“。 传统on-premise server farm的问题在于,如果一上来就是高配置,而用户量很小,造成巨大资源浪费;如果开始低配置,用户一旦多起来,系统性能瓶颈就会影响用户体验。而升级server farm的过程,又耗时耗力。 某些极端情况下,on-premise server farm是无解的。例如购物网站的高峰期(双11,boxing day, thanksgiving ,etc). 平时就保有能处理极端高峰期的server farm是非常不合算的,但是配置不够,极端高峰期的用户体验必然下降。 而云服务平台的”按需使用,按实际使用量付费“就解决了这个问题。
这里说AWS EC2只是举个例子,国内的阿里云什么的,也是同样原理。
不知道他说的有没有道理,请多多指教。
,AWS, Azure
不想说啥,我不懂on-premise server farm和云服务的区别,就是想问问他的理解对不对。
这就是说,作为用户,使用AWS是没有什么技术含量的,是吧? 那么问题来了,很多简历把会使用AWS作为一种skill,是什么道理?
会用aws上手快啊。
说的是对的,而且背后的技术并不简单。使用普通服务器,做大规模并行,包括自己弄文件服务器阵列。。真的不容易。 特别是a家和g家是从0开始趟路的。
里面有很多配置和know how的问题,会的不难,没做过的不知道还有这些鬼。

不谈股票,只是了解下技术。

有一点我不同意,系统管理员并不贵。 最主要的原因是,为了迎合股市,公司管理层把减员本身作为了目标。
十几年前看到过一个有关IBM的数据,美国本土减员,外包,节省下来的钱,平均到每个裁员上面,少得可怜。 记不太清了,好像是,美国本土丢掉一个工作职位,去掉外包成本,一年不过节约一万美元出头(或者还不到)左右。
特别是一些初创公司应对短期市场活动带来的大流量和高并发,用第三方云是最省事的,自建没有那么快,而且浪费很大,各方面成本很高。
另外目前几个主流的云服务除了都知道的运算,存储,带宽之外,还有更多的服务,比如数据仓库,RTM,一些直接可以用的service,省了很多事情。
所以现在企业级的走法都是混合云了。怎么个混法就还是八仙过海的阶段。
