The world is covered by the cloud

With the advent of the large data age, the concept of cloud computing is increasingly known to the public. According to the National Institute of Standards and Technology (NIST) Definition: Cloud computing is a pay-as-you-go model that provides available, convenient, on-demand network access, into a configurable pool of computing resources (resources including networks, servers, storage, applications, services) that can be quickly delivered, You need to invest in very little management work or have little interaction with your service provider.

The advent and popularization of cloud computing has undoubtedly injected fresh blood into the IT world, and as an innovative technology model, it is affecting the technology pattern and trend of the whole industry. Following the changes in personal computers and the Internet, cloud computing has created a new wave of IT industry for the third time.

Cloud computing includes infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS). IaaS primarily provides infrastructure-level services that provide users with basic computing resources such as storage space, network connectivity, firewalls, and so on. PAAs is a platform-level service, actually refers to the software development platform as a service, that is, an application of the SaaS model. SaaS is the software that we touch the most, the service, the cloud provider installs and maintains the software in the cloud, the user rents and uses the model through the cloud.

With the development of cloud computing, all kinds of cloud applications have been developed now. such as cloud objects, cloud security, cloud storage, cloud call, and so on. Cloud computing provides great benefits to the enterprise, but also creates huge business opportunities for the suppliers, so it attracts many enterprises to join in the cloud computing market.

Among the many companies involved in cloud computing, the company we are most familiar with is Microsoft. The advent of Windows Azure indicates that Microsoft has entered a new cloud computing field. At the 2008 Microsoft Developer Conference, Azure Services Platform, a new cloud computing platform, is a PAAs platform service that provides developers with an online environment for the development, storage, and service hosting of Windows products. Azure has launched 5 hosting services, including. NET application services, SQL Services, SharePoint Services, Dynamicscrm services, and live services. At present, Microsoft is still in the planning of cloud computing applications, and constantly improve the perfect azure services. As a veteran of the IT world, Microsoft has a well-established operating system and a sophisticated office suite base. As we all know, Microsoft is not good at innovation, but the grasp and analysis of the market is often the key to its success. In terms of cloud computing, Microsoft has already planned a clear roadmap for future development.

Of course, the application of cloud computing is not limited to the PC, the concept of mobile cloud computing is used in the telecom industry, let people see the cloud and mobile Internet integration of new opportunities. At&t, an American telecoms company, has many advantages in infrastructure for telecoms companies, without having to waste money on cumbersome infrastructure. Moreover, the application of cloud computing to mobile devices has attracted more and more public attention. IBM recently announced at the 2013-year technical summit that it will join hands with At&t to help companies deliver high-performance mobile applications. People's lives are becoming more and more dependent on mobile devices, whether in life or business, which has become a trend.

International companies have achieved remarkable results in cloud computing, and more and more domestic companies are also doing well in the cloud computing market. Aliyun is one of the representative cloud computing companies in the country, which was set up by Alibaba Group in 2009 to focus on the basic services platform of cloud computing, and independently developed the cloud computing platform "flying". Its products also include flexible computing services, open Storage services, relational database services, open Data processing services, and so on. In the future, cloud computing will evolve into a convenient public service. Efficient green data centers and large-scale distributed storage and computing that support different Internet applications are the basic core technologies for creating next-generation Internet service platforms. Aliyun, as a nascent domestic cloud computing company, can be expected to build the first platform for Internet data sharing and become a data-centric, advanced cloud computing Service Company.

There are still a lot of companies involved in cloud computing, and there is a continuing business presence that makes the development of cloud computing a limitless possibility, and the future of cloud computing is worth watching.
