Cloud computing: A double-edged sword hanging over the head of a data center

What benefits cloud computing can bring to data centers, I believe the answer will be the same. For example, it lowers the energy consumption of the data center to some extent, improves the efficiency, and is more environmentally friendly. On the premise of resource optimization on demand, there will be some equipment utilization rate is high, some equipment utilization rate is low, the utilization of low equipment can carry out hibernation condition. In small and medium data centers, an average of 170 servers per worker can be managed. In large data centers, with the support of professional teams and tools, each worker can manage more than 1000 servers at the same time. Thus, the cost of human resources can be drastically reduced.

For http://www.aliyun.com/zixun/aggregation/15530.html "> Large enterprises, how to transition from the current inflexible and inefficient data center to private cloud becomes the important content of the future data center construction." and small and medium-sized enterprises can more use the power of public cloud service providers to obtain more efficient and more economical computing resources than now.

In addition to technical aspects, a senior cloud computing architect also believes that the adoption of cloud computing will also trigger the transformation of enterprise IT management architecture. In the traditional data center, server, storage, network in the structure of the separation of clear, there will be their own operation and maintenance management team, and cloud computing technology will be the data center of the server, storage, network resources together to form a unified pool of resources. This will not only be matched with the management tools to change, the enterprise IT management structure will also change.

In the area of industrial distribution, cloud computing providers generally use large-scale data centers, more professional than small and medium-sized data centers, higher levels of management, lower cost of unit computing, and more scientific and financial input from professional cloud providers to drive data center innovation. The cloud provider also has more sophisticated software, including a management team with a wealth of knowledge and experience, and management software associated with it. Thus, cloud computing brings a more professional division of labor, and further optimize the IT industry pattern. By allowing professional people to do professional things, each take the director, avoid weaknesses, effectively avoiding the IT industry may produce internal friction. On the other hand, professional division of Labor has also bred a new industry opportunity.

However, the advent of cloud computing, some industry experts have seen the data center company overhead clouded.

Among them, the concern for compliance is one of the main reasons that prevents many companies from using cloud services. Low price, flexible computing, can be created, disassembled, reconfigured, expanded and contracted according to requirements, which are attractive features, but does it include the necessary regulatory requirements?

In addition, the cloud's investment return pressure will increase. More and more companies may choose the "cloud first" option, but will not take away the relentless pressure to show a quick return on investment. The traditional it world has felt for the past more than 10 years, and so far the cloud approach, as they make new and changed the rules of the game, have been passed. The cloud became normal and accepted as part of the business, and it was subject to stricter scrutiny. Part of the calculation will need to include business continuity provisions, and last spring the Amazon Network service outage showed that too much reliance could raise its price. The bottom line is that not just to have a cloud, the cloud needs to realize the commercial value. In many cases, the cloud may not be the most efficient method.
