The Essential Reason and Technical Value Behind "Going to IOE

Zhejiang Mobile to IOE road has gone a few years, from the questionnaire is also full of achievements: a considerable proportion of clouds, I almost finished (no technical bottlenecks, a small amount of old equipment gradually off-line as planned) E is not too much left (there are a small number of technical bottlenecks), O basic control in the CRM core transaction library, but also completely realized the CRM core database hosting x86. Core CRM application container-based micro-service, enterprise-level micro-service platform has begun to take shape, development and operation mode of agile transformation continued to promote. Now, it's time to look back and re-examine the IOE. The first core question: What is going to IOE? IOE is not a scourge, IOE and we have no hatred, IOE can not literally understand, can not go away. IOE has played a key role in history. For some time to come, there may not be no suitable application scenario. Even when it comes to technology development, there is also a saying called veteran immortality, which only gradually dwindles. There is no overnight or non-trivial matter. National Security Information Security? Level is too high, the top decision-making is our grass-roots implementation is, I do not comment on the issue should not be discussed, I just need to make it clear that the level of technical transformation of the cost and program, while doing a good job on the line. We turn technical problems into economic problems, and as long as we can afford the cost, we can ensure that we have the ability to execute. The essence of going to IOE Ali proposed a marketing slogan, technically not rigorous. Lack of rigor is behind the overall revamping of Ali's IT infrastructure, which reworked underlying infrastructure changes and, in fact, overshoots the rebuild of the application architecture. On the one hand formally removed (at least most of the IOE removed), but also for the construction of Aliyun business laid the technical foundation; on the one hand to promote the application of cloud services and micro-services, to promote a comprehensive structure decoupling, agile transformation, organizational restructuring , Promote small IT business transformation of medium and large Taiwan, to plug in the wings of business innovation, redefine the boundaries of enterprise IT and business. Ali went to IOE a good illustration of the value of IT lies in innovation , is to allow you to do things that have not done before, not just to save costs. The value of IT is offensive rather than defensive! Ali why this application architecture reconstruction it? A few years ago, Ali technicians to see Ali implementation of IOE reasons:  Annual GMV are growing rapidly (business growth too fast)  Annual infrastructure investment outpaces GMV growth (infrastructure investment growth exceeds GMV growth)
 The dilemma of a centralized core database:  - Unstable (downtime) affects network-wide access (centralized data storage can not be isolated in the event of a failure) - Expansion costs are high (minicomputers and commercial databases are too expensive)  Through the above information and data, we can see that Ali "double eleven" volume of business in a short span of 8 years turned 3360 times. Ali, the most important reason for the IOE transformation of enterprise IT systems, is that the original centralized commercial database architecture can not meet the ever-increasing business requirements. Although we do not underestimate Ali's tremendous efforts and achievements in the process of going to IOE, we can not completely interpret this as far as the information security of the country is concerned.  In some traditional enterprises, there are thousands of faces to the IOE. For so many years, the mainstream view still stays in two directions: First, the resistance is too large to dare to go and does not want to go; Boosting is often thought of as an innovative area of cost savings.
