Go astray and find the end of the cloud again

Is cloud computing "misguided"? Why is the enthusiastic cloud industry encountering the corporate CIO's snub? We see that by internet companies triggered by the cloud computing boom, actually did not answer the real problem of enterprise informatization, resulting in cloud computing hype more, and difficult to achieve landing in the enterprise. This is like the landing of a cloud computing "dislocation"-internet companies to promote the cloud computing model can not be "copied" into the enterprise calculation.

"Existing IaaS, PAAs and SaaS Technologies, as well as extended business models, do not meet the needs of enterprise informatization for cloud computing." "We believe that the SaaS model adapts to individual computing and small and medium sized enterprises, and it can only serve as a supplement to Non-core systems, while SaaS model has been unable to solve the problems of enterprise personalization application implementation, data continuity and service migration, and interoperability between cloud services; by Google, Tencent and other proposed open cloud computing development platform, is actually based on private architecture and personal application-oriented two-time development interface, can not be called a real PAAs, and enterprise ERP docking is difficult to achieve, essentially not an "open" platform but a "release" Platform, Freeing up some partners to extend some of the new applications based on their infrastructure, the development of a new business process-driven enterprise application system is basically not feasible; At the IaaS level, cloud computing can reduce the cost of software and hardware, but the existence of the hidden costs of later operation maintenance, data management, training, The total cost of ownership has not been significantly reduced.

We believe that internet-based cloud computing, success depends more on the innovation of the business model, and the real core of corporate cloud landing and success is it governance issues, it is essentially a new model of enterprise information construction. At present, many enterprises ' IT governance has many bottlenecks, such as enterprise diversification investment, rollout, low-level duplication construction, low application level, total investment, no economic scale effect; it resource utilization efficiency is low, resource average utilization rate is between 10% 20%, waste is serious; business leading system (Business Monarchy) decision-making model, resulting in isolated systems, lack of enterprise architecture, operating costs far exceed procurement costs. This change in IT governance mode is also the institutional guarantee for cloud computing to fall into the ground. Technically, enterprise cloud must combine virtualization technology with SOA architecture to virtualize core IT resource management, not only to virtualize servers, storage, and networks, but also to virtualize data, applications, and processes through SOA, and to achieve flexibility in application and the removal of islands of information, Reduce IT operational costs.

"The landing of corporate cloud computing is essentially a new IT governance model." If this problem is not solved, cloud computing will be impossible to talk about. "As a result, cloud computing in the enterprise landing has three important support points: one is to support the cloud computing IT governance model and enterprise architecture method; The second is the SOA architecture of the PAAs platform to support enterprise business, application, data integration, application flexibility and the elimination of information islands, and realizes the enterprise each business unit's Personalization Service application development, the deployment and the management; The third is realizes the centralized management of IT resources with the virtualization as the core, reduces the operating cost.
