Talking about DELL's acquisition of EMC

EMC has grown from being tall to being unloved by grandma and uncle. The ending of EMC is not accidental, but inevitable. IBM and Sun are its lessons. In the case of reference between previous vehicles, EMC has accumulated a lot, and being acquired by DELL may be the best outcome.

The giants of these technology fields, Oracle is the best at doing it, and it has not been affected by several industry reshuffles.

IBM gave up selling PCs and servers to Lenovo, and shifted its focus from hardware to software. I think "International Business Machines Corporation" should be renamed, it should be called "International Business Software Corporation", from hardware R&D and production to software ODM (Original Design Manufacturer) ) This is a breaking change.

The worst ending is Sun, Nokia.

From solution to user selection

The early giants will provide solutions for various fields. The giants will choose a field, conduct their own research, develop their own products, and launch their products to the market. The solutions will be packaged and sold to industry users along with software and hardware, and products will be continuously improved according to market feedback. , and launch an upgraded version.

The process is dominated by giants, often with generic products. Once some solutions of the giants are implemented, they will be kidnapped, after-sales, service, etc...

With the passage of time and entering the Internet era, general-purpose products have been different to meet the needs of users. Users need personalized customized products. At the same time, there are higher requirements for the version release cycle. I have released a basic version every few years or a version to meet the needs of users. .

Users are no longer blind and ignorant. Users are very clear about what products they want. The needs of users are like snowflakes. The giants are overwhelmed, and the initiative has shifted from giants to users.

The giant's plan is not working, users are tired of monopoly and kidnapping, and users start to seek open source applications, I call it "open source revolution"

data and storage

Speaking of storage, the early computers were subject to the technical storage at that time, and storage was a difficult problem. EMC, NetApp, IBM, etc. all achieved brilliant results in the background at that time.

Technology is constantly improving. With the concept of distributed, we first solved the storage problem of web server and ftp server, but there is no better solution in the field of database.

The emergence of distributed file systems has lowered the threshold for distributed storage. Users can use distributed file systems just like local file systems. At the same time, distributed file systems can solve problems such as file synchronization, backup, and failure recovery. The distributed file system has extremely strong scalability, and it is no longer a problem to store TB and PB-level data. The main thing is that the cost is extremely low.

存储只是一个大硬盘

对于软件开发人员来说，EMC就是一个大硬盘而已。数据存储起来是没有意义的，数据挖掘与计算更重要。

在数据挖掘的时候开发人员并不关心，后端存储有多高大上，他的需求就是能够快速IO操作。

对于企业来说考虑的是成本与性价比，相同成本下采用分布式文件系统与EMC存储比较，前者完胜后者，用户没有理由选择EMC的解决方案。

开源的力量

巨头的销售通常这样说，使用开源软件如果出了问题怎么办，你作为IT部负责人要承担责任，我们有认证工程师上门解决。我想很多人都听过这样的话吧？

实际上刚好反过来，你使用巨头们的软件处理问题怎么，你作为IT部负责人要承担责任，他们的认证工程师很水，搞一个上午搞不定，还要向厂商反应，再拍人过来。巨头们的产品一旦出现问题，别想得到及时解决，最多给你显示一个错误代码 “00053324”，你根本无从下手。巨头的软件出现BUG你别想他会给你快速修复，他们会安照他们的节奏推出补丁。

开源应用社区很活跃，版本迭代快，反应问题都能够即时响应，在下一个版本中得到解决，很多社区提供nightly版本（每天晚上产生一个可用的版本）。所以很多企业捐款赞助开源社区，甚至派自己的员工专职参与项目开发。这是共赢模式越来越多的企业参与进来。
