Cloud computing industry forms two big monopolies

The concept of "cloud computing" is rapidly rising around the world: 2010, China's cloud computing market size reached 55.93 billion yuan, an increase of 29.3%. It is estimated that 2011-2015, the annual composite growth rate of more than 50%. 2011 Global Cloud Computing Market size will reach 40.7 billion U.S. dollars, 2020 will increase to 241 billion U.S. dollars. By 2015, China's cloud computing industry chain will reach 750 billion to 1 trillion yuan.

But equally rapidly, the world of cloud computing has in fact formed two big monopolies. Among them, the first big monopolies are Amazon and Google, the second largest monopoly is EMC and VMware.

The first big monopolies: Amazon and Google

Google

Hardware advantage, large data center, search engine is to promote the rapid development of Google Cloud computing three big power. The Google Cloud infrastructure model includes four separate, tightly knit systems: Google file system, which is built on top of the cluster, and the Map/reduce programming model proposed for Google Apps, Distributed lock mechanism Chubby and the model simplified by Google developed a large-scale distributed database bigtable.

Google also builds other cloud computing components, including a domain description language and a distributed lock service mechanism. Sawzall is a domain language based on MapReduce, which is devoted to large-scale information processing. Chubby is a highly available, distributed data Lock service, and when a machine fails, Chubby uses the Paxos algorithm to ensure backup.

Google specific cloud computing products include the following:

Docs is the first cloud computing application, belongs to the S layer, is similar to Microsoft Office's online Office software.

Apps is a Google Apps suite that integrates management functions such as Cmail, Googletalk, Google Calendar, Docs, and the latest cloud apps Googlesites, API extensions, Can be better to achieve synergies anytime, anywhere.

Googlesites is Google's latest cloud computing application that can be used to create a variety of team sites as a component of apps.

Google App Engine is a platform composed of Python application servers, bigtable databases, and GFS to provide developers with integrated host servers and an automated online application service.

There are signs that Google's cloud-computing goals are not just for individual users, but for the vast majority of space from individual users to corporate users. Google is also actively working with other cloud computing companies. Google, one of the world's most influential High-tech companies, is embracing the era of cloud computing with a pioneer attitude.

Amazon

Amazon is the internet's largest online retailer, and its cloud computing platform, the flexible Computing cloud EC2 (Elastic compute cloud), can effectively address the waste of resources and make Amazon the first company to sell infrastructure as a service.

As early as March 2006, Amazon released a simple storage service (simply Storage SERVICE,S3), paid for the service in the form of a monthly rent, and in July 2007, the simple queue service was rolled out (easy queues Service,sqs), With this service, application writers can transfer data between distributed programs without considering the problem of message loss. On the basis of the above services, Amazon has optimized and transformed the existing platforms of the company, opened the service interface and developed a EC2 system that is open to external developers while safeguarding its retail application business.

Unlike Google's cloud computing services, Google offers cloud computing platforms only for its applications on the Internet, and independent developers or developers cannot work on the platform, so they can only develop cloud applications with Open-source Hadoop software support. Amazon also does not sell the physical cloud computing services platform, but instead builds its own flexible computing cloud on a platform of large-scale cluster computing within the company, where users can operate on the cloud's web interface to manipulate individual instances (Instance) And the payment method is determined by the user's usage condition, that is, the user only needs to pay for the computing platform instance that he uses, and then the billing is ended after the running. The example described here is a complete virtual machine run instance controlled by the user. In this way, users do not have to set up their own cloud computing platform, saving equipment and maintenance costs.

In the future development of the flexible computing cloud, Amazon has also planned how to help users develop Web 2.0 applications on top of the cloud computing platform. Amazon believes that, in addition to its reliance on the online retail business, cloud computing is the core value of Amazon. It can be foreseen that in the future development process, Amazon will be in the flexible computing cloud platform to add more network Services Module modules, for users to build cloud computing applications to provide convenience.
