Cloud computing will depend on data center

Large data centers are the basis for cloud computing. Selling computing resources to other people is a nightmare before today's incredibly large modular datacenter emerges. Scalability, availability, resilience, and security are factors that must be factored into data center design in one way or another, from the structure of the building in which the data center resides to the software used on each server. Otherwise, any commitment from the cloud vendor will not be realized.


Cloud Computing Vendor Commitment


's major commitment to cloud computing vendors, especially in http://www.aliyun.com/zixun/aggregation/13674.html "> Infrastructure, the service sector, we can see Most of these commitments depend on the problems that arose prior to the establishment of the data center. For customers, the promise of a healthy operation seems simple: I can access and use resources when the service is running properly, and I can't access resources for some kind of dysfunctional operation. For service providers, the problem is much trickier: the service may not function properly because of a server or disk failure, or a major outage. Many lower-level issues, such as power or network connections, are associated with larger issues, such as where the data center is built.


in many countries, you cannot simultaneously access two independent external power supply suppliers. The fact that it could force companies to invest more money to buy generators or other back-up energy has undoubtedly increased operating costs. On the web, too, the same problem: the inability to access multiple vendors, companies may be forced to deploy their infrastructure, or even "abandon themselves" to the fact that they may not be able to achieve a certain level of availability.


scalability is another interesting issue. The (almost) unlimited scalability of cloud computing service providers means that they must continually increase their usable capacity in order to be able to meet any additional requirements. Infrastructure providers need to add hundreds of or even thousands of servers each day to their data centers, not only to replace faulty devices, but also to meet future needs. Putting scalable resources in the hands of an infrastructure end-user will lead to the fact that you don't know the maximum amount of resources a single user might need (which is why most cloud service providers have virtual limits on the number of servers available to a single account).


Even simple things like Amazon's available areas (where multiple data center locations are close to each other, with a low latency connection) can also create design and management complexities. In the case of Amazon, uptime is a measure of multiple available areas, not a single free zone, which must be sufficiently dispersed, so that external problems affecting one of the available areas do not affect other available areas, and distances are not too far away to ensure a low latency connection. At the same time, they represent a new datacenter concept: Multiple data centers can be run as a single data center.


Cloud computing and data center neck


as deployment rates grow, cloud computing will continue to drive the evolution of data centers, from architecture to software and control processes. Broader deployments will not only force data center operators to rethink their internal operations, but also require them to adapt to new emerging requirements. With the increase in usage, there is also an increase in energy consumption, and as the computing resources provided by vendors become more diverse, the environment will become more diverse and management will be more complex. Simple measures, such as using external air to replace air-conditioning, will help businesses save millions of of dollars.


If cloud computing brings the commercialization of computing resources, data centers will need to be optimized to allow businesses to survive by selling these resources. Since cloud computing will depend on data centers for the foreseeable future, the evolution of these two technologies is certainly linked, and anyone who is concerned about one of these technologies should pay close attention to another technology.
