The IOE architecture uses IBM minicomputers, Oracle databases, and EMC storage devices. All three are overseas IT giants. Among them, IBM represents hardware and overall solution service providers, Oracle represents databases, and EMC represents data storage.

What does ioe architecture mean?

IOE has been eliminated, or there are more choices instead of only using the IOE architecture. (Recommended learning: PHP video tutorial)

There are two specific explanations for going to IOE

One refers to the upgrading of IT architecture. Specifically, hosts represented by IBM, relational databases represented by ORACLE, and high-end storage devices represented by EMC are replaced by new cloud computing technologies. , which is what we often call "cloudification". Among them, hosts are replaced by X86 devices, traditional databases are replaced by open source database products, and high-end storage with SAN structures are also impacted by cloud storage products and systems. Any of these three aspects of work can be labeled as a specific manifestation of "de-IOE".

The second one refers to the "hard crackdown" on foreign IT equipment, especially American products, reducing or even no longer purchasing products from IBM, ORACLE, EMC and other companies.

As early as five or six years ago, China Mobile began to study the cloud evolution of business support systems. At that time, virtualization technology had been widely used in systems, but implementing a comprehensive cloud transformation of a large-scale business support system faced at least three problems:

First, it was the problem of flexible allocation and deployment of resources. Virtualization technology can cut large computing resources into small pieces, but there are still many technical problems that need to be solved whether these divided computing resources can be flexibly used and whether they can be regrouped to form new computing capabilities. If the resource pool cannot be flexibly allocated between systems, not only will it fail to improve the overall efficiency, but the system efficiency may even be reduced due to excessive consumption when resource calls are made between systems.

Secondly, there is the issue of how application software adapts to the cloudification of hardware. IOE manufacturers have put a lot of effort into software. While providing additional functions, they also pay attention to improving the performance and stability of their products. In the face of the X86 open platform and open source software, many software need to be redeveloped or customized. The increase in application software development also brings uncertainties to the stability of the system. This also means that under the new technical architecture, system software and application software are integrated, and developers have to bear a dual development workload.

Third, it is to establish an operation and maintenance management system that supports cloudification of the system. The introduction of cloud computing technology enables flexible allocation of computing resources, but it may introduce a disaster for system maintenance and management. Traditional division of labor interfaces, workflows, emergency plans, etc. will gradually change as the degree of cloudification of the system increases. Especially for software maintenance, it will face huge and even subversive tests.

Because of the many problems faced, China Mobile is actively and steadily exploring and implementing cloud transformation in an orderly manner. Initially, the access layer implemented a comprehensive cloud desktop transformation; later, the access module of the CRM system and the billing details storage of the BOSS system were piloted on the cloud. The transformation includes not only virtual machine and , progress in aspects such as distributed and open source is more radical.
