The ultimate goal of cloud computing needs landing

Every time you talk about the development of the Internet, everyone will be very optimistic about cloud computing, think it will be the future of the Internet development, so in understanding this aspect of the content while deciding the following content on the concept of cloud computing understanding and argument is better, so Share hope to help cloud computing friends.

If you count the current IT trends, cloud computing will do my part. What exactly is the cloud? Although there is no text-based definition of clouds today, the description of clouds is everywhere. For example, a description given by the National Institute of Standards and Technology is that cloud computing is a model of how IT resources are used to provide ubiquity of shared, configurable computing resources such as networks, servers, storage, applications, and services , Standard, on-demand web access. The use and release of resources can be done quickly without much administrative cost.

Cloud computing is not a new technology. To say where it is new, cloud computing can be said to be a new mode of IT resource usage with three new points of dynamic, configurable, on-demand access and automated management ; In addition, cloud computing allows IT resources to be as easily accessible as utilities and to deliver IT resources and services to subscribers on a leased basis, bringing with it a new business landscape and a new service economy model .

So, the cloud can bring us what? For consumers, access to IT resources will be more flexible and convenient, through a small handheld terminal, anytime, anywhere, on-demand access to powerful computing and storage resources, without having to Go shopping for these expensive computing devices; and for the enterprise, the cloud offers a new avenue for simplifying IT by building an enterprise private cloud that can reduce IT investment costs and gain an on demand computing environment.

According to statistics, 80% of the current IT spending on most enterprises is for the operation and maintenance of IT infrastructure, rather than R & D and innovation. If cloud computing is implemented, companies can make IT no longer a burden, but it can also create value. For example, by implementing a cloud, organizations can leverage existing resources to meet the ever-increasing demands for business workloads, reduce the cost of building and maintaining IT infrastructures, monitor effectively for business continuity and system updates, and use resources flexibly and accurately.

This is also the hottest reason for cloud computing. Its impact is not only on IT, but also on the entire industrial chain. At the same time, cloud computing has brought tremendous commercial value. Gartner predicts that by 2016 all of cloud services Spending will reach 207 billion U.S. dollars, double this year. The huge commercial value of almost every corner of IT are moving closer to the cloud, the traditional IT vendors have changed their identity, cloud computing solutions provider to become a common goal.

Big step forward in cloud computing led to the explosion of virtualization applications. Virtualization is not a new technology anymore. As early as more than 40 years ago, IBM first implemented virtualization on a host computer and then extended it to minicomputers and x86 servers. However, the rapid development of virtualization was still in the last decade , Especially the rise of cloud computing, has greatly promoted the development of application of virtualization. Virtualization is a good way to solve the traditional single-machine single-use mode, which can improve resource utilization, server consolidation, and solve data center space and energy consumption issues.

Today, IT develops from the mainframe era, PC era, now has entered the virtual era. According to statistics, the virtualization ratio on x86 servers will reach 80% in 2016 from 40% in 2011; and the virtual desktop will reach 50 million by 2014; 60% of the new server load will be virtualized; By 2020, global spending on cloud computing will reach 241 billion U.S. dollars. The wide range of virtualization applications is changing the way IT is used. Integration of virtualization, resource pooling, unified management and other characteristics of cloud computing and demand is very fit, usually think that the implementation of virtualization is the first step into the cloud.

In early 2012, IDC released the Guide for China-based Cloud Computing Consumers to make cloud computing construction planning in five aspects: planning, preparation, implementation, deepening and application. IDC emphasizes that enterprise-class virtualization is the foundation of cloud computing. Building enterprise-class virtualization platforms that support heterogeneous platforms and meet the requirements of security, reliability, scalability, and agility is the only way to build cloud computing.

Since virtualization is the first step in implementing cloud computing, its importance is self-evident.

So, what are the issues that need to be taken into account when implementing virtualization? Of course, the first thing to consider is security. After all, this pattern of putting all the eggs in one basket has inherent risks. If it is not handled properly, deploy virtualization and implement Cloud computing may not be so smooth.

The deployment of virtualization, the following points need attention:

First, the implementation of virtualization, perhaps not as imagined to save money, in addition to the need to purchase servers, storage and other hardware, virtualization software is not cheap, how to effectively use virtualization software is the first thing to consider.

The second is hidden in the communication between multiple virtual machines on the same system. Although virtualization software can move a running virtual machine from one machine to another, it also reduces the effectiveness of network security.

Third, in the safety assessment, the future must create a safe and reliable virtual machine management procedures.

Fourth, virtualization technology has brought additional software space, the resources occupied by the communication between the virtual machine can not be ignored.

Fifth, there is no universal standardization of virtualization technology. Without careful selection, companies may find themselves locked in to a vendor, making it otherwise difficult and expensive to adopt other approaches as technology matures.

Sixth, different hardware processors for virtualization transfer there will be some obstacles.

Cloud computing is not a go-between. It can solve all the problems in IT. First, it needs to clarify its own needs and business conditions. Starting from the application, the best technology may not be the best for itself. Cloud computing needs to be the ultimate goal.
