The trend of future development cloud computing will be a big way

Looking back on the development of the Internet, we cannot help sighing that the world is changing fast. In the 90 's, when we opened the old Mosaic browser, we saw only the words. Since 2000, thanks to the development of network bandwidth, storage capabilities, CPU computing performance, we have seen dazzling images and video, and heard the best music. And today, we are entering a more exciting world: a 3D Internet world, and perhaps soon, you will be able to let your average figure of 3D virtual agents to go online in the major 3D virtual clothing stores to try, custom-made clothes. As mental images CEO and chief technology officer Rolf Herken said, "Everyone can feel the web as they feel the real world." ”

As virtualization and service-oriented architectures penetrate into the enterprise, loose services running on a flexible, scalable infrastructure should eventually make each enterprise a node in the cloud, which is bound to be a trend for the future. In all future trends, however, cloud computing is arguably the most controversial.

For now, cloud computing is probably more accurate than the description of Sky computing, and it's not so confusing from the point of view of the value of IT pros. "Cloud computing has become the mainstream of the industry," according to Ben Lin, a senior analyst at Gartner Consulting. The problem is that, like Web 2.0, everyone has a different definition of cloud computing.

As a metaphor for the internet, "cloud" is a relatively close statement, but when the cloud and "computing" together, the meaning is more far-reaching and misty. Some analysts and vendors define cloud computing narrowly as an updated version of Utility computing: essentially a virtual machine delivered over the Internet. Others have defined it more broadly, thinking that anything that is used outside the firewall is on the cloud, including traditional outsourcing services.

When you consider the general requirements of it, cloud computing focuses primarily on ways to improve or increase performance without having to invest in new infrastructure, new employee configurations, or new software license authorizations. Cloud computing includes any subscription or on-demand payment services that can extend it's existing capabilities through the Internet in real time.

Cloud computing is still in its infancy, with different sizes of providers delivering a range of cloud-based services, ranging from fully flowering applications to storage services to spam filtering. Yes, infrastructure providers in utility form are part of cloud computing providers, but software such as Salesforce.com, a service provider, is also a provider of cloud computing. For most users, it must also use cloud services alone, but the aggregation and integration of cloud computing has emerged.

The following is a detailed breakdown of various aspects of cloud computing:

1. Software as a service (SaaS)

This type of cloud computing uses a multi-user leasing architecture to pass a single application to thousands of users through a browser. From the user's perspective, cloud computing means there is no upfront cost of licensing the server or software licenses; From a provider's point of view, only one application is maintained, which is much cheaper than traditional hosting. So far Salesforce.com is the most well-known example of delivering an enterprise-class application provider, but software as a service is very common for human resource applications and even needs to have its own way to meet the needs of ERP systems. Who can predict the sudden rise of software, such as Google Apps and Zoho Office?

2. Utility Calculation

The idea of utility computing is not new, but this form of cloud computing has been reborn from Amazon's online, SUN,IBM and other vendors who currently provide access to storage and IT departments on-demand virtual machines. Early enterprise users used utility computing primarily to meet non-critical requirements, but perhaps one day they would replace a part of the datacenter. Other providers can provide solutions to help IT organizations build virtual data centers from commercial servers, such as the 3Tera applogic and cohesive flexible technologies elastic server on Demand. Liquid Computing's LIQUIDQ can also provide similar capabilities to enable it to integrate memory, input/output, storage, and computing capabilities into virtual resource pools that are used over the Internet.

3. Network services in the cloud

Web Services in the cloud are closely related to software, which provides users with an application programming interface to help developers develop applications via the Internet rather than delivering fully flowering applications. Cloud Network service providers can provide continuous enterprise services, such as strike Iron and xignite, through Google Maps, ADP payroll processing, USPS services, Bloomberg and even traditional credit card processing services to provide a comprehensive application programming interface.

4. Platform as Service

Platform as a service is a derivative of the software, this form of graduate students can be the development of the environment as a service delivery. Users can build their own applications to run on the provider's infrastructure and pass the Internet from the provider's servers to their users. such as Vegging-out, these services are limited by the manufacturer's design and capabilities, so you cannot achieve complete freedom, but you can anticipate and integrate ahead of time. Representative examples include Salesforce.com force.com, Coghead and the latest Google application engine. For extremely common research and development work, there are cloud-based platforms such as Yahoo Pipes or dapper.net.
