http://blog.csdn.net/it_man/article/details/8441902

Over the past two years, with the rapid development of cloud computing technology, more and more manufacturers are aware of its huge potential value. With billions of businesses investing in high-tech companies such as Microsoft, IBM, Google, and Amazon, Cloud computing has become the hottest and most topical topic in the information and communications industry. Analysts say cloud computing is a new, low-cost, efficient way of IT services that will lead the next wave of information communication!.

Recently, Gartner, a leading international market research firm, commented that cloud computing was the most influential it technology of the 2010 and the most strategic technology for many companies in 2011. It is also estimated that the global cloud computing market will exceed $150 billion by 2015. At the 2010 China Mobile Developers Conference yesterday, Microsoft Greater China President Mr. Leung, Innovation Workshop President Lee Kai-Fu, China Mobile Research institute Dean Mr. Bill Huang, Rim Greater China President Shea, Baidu Vice President Shawn, Sina Vice President Wang Gaofei and many other industry experts said: cloud computing is the future development of the IT industry trend!

So, what exactly is cloud computing?

In general, cloud computing is an emerging approach to shared infrastructure that connects huge system pools to provide a variety of Internet-based IT services. Including CRM Customer Relationship management system, ERP enterprise resource management system, online marketing tools, product life cycle management tools, supply chain process management tools and so on. Cloud computing can also extend to technology-level services such as software development, IT infrastructure, and more. This is also the recent development of a faster cloud computing business.

Survey and analysis data show that in recent years, data and business processing demand has exploded growth, which provides a higher demand for data center processing capacity, traditional IT service providers have to spend a lot of effort to upgrade existing systems, and the cost of upgrading is huge. Cloud computing provides a new, low-cost alternative to providing users with low-cost data center scalability, IT infrastructure, software, and a variety of new applications, while guaranteeing quality of service.

Seeing here, you may still ask, how does cloud computing provide infrastructure for us through the Internet? How do I develop software and products through Internet access to the cloud platform? How do I use cloud computing to run the core applications of my business?

In fact, it is very simple, there are three main ways of landing cloud computing, namely: Saas,software-as-a-service Software as a service; Paas,plartform-as-a-service platform as a service; IaaS, Infrastructure-as-a-service infrastructure as a service. The following author will do a detailed explanation.

SaaS, software as a service

SaaS is Software-as-a-service (software-as-a-service) abbreviation, with the development of Internet technology and the maturity of application software, and in the 21st century began to rise in a completely innovative software application model. It is the most mature and most widely used service in the field of cloud computing. It is a way to provide users with software and application services through the Internet. SaaS is also known as "on-demand" software because SaaS-based software is used only when users need it. The SaaS model greatly reduces the cost of software, especially for large software, and because the software is hosted on service provider servers, it reduces the cost of management and maintenance of the customer and is more reliable. Salesforce is a typical representation of the SaaS model.

Second, PaaS, platform-as-a-service

PAAs is Platform-as-a-service (platform as a service) short, is the computing environment, development environment and other platforms as a service to provide a business model. Cloud service providers can provide platform-level products such as operating systems, application development environments, and services to users through the web. With PAAs services, software developers can develop new applications without the purchase of a server. Google's app engine, Microsoft's Azure, is a typical representation of PAAs services.

Iii. IaaS, infrastructure as a service

IaaS, the abbreviation for Infrastructure-as-a-service (infrastructure as a service), is the business model for assigning data centers, infrastructure hardware resources to users through the web. The most compelling example of IaaS is Amazon's elastic Compute Cloud. Traditional IT service providers such as IBM, VMware, and HP have also launched the corresponding IaaS offerings. It is worth mentioning that the IaaS service is a good way to realize the concept of pay-as-you-want cloud computing, through the "elastic cloud" users can only access these infrastructure resources when needed, and only for their own use of the part.

See here, and perhaps you will ask, what is the difference between IaaS, PaaS, and SaaS? In fact, the boundaries of these three areas are not as clear as people think, and there are many intersections between them. Most cloud service providers are not just offering a single service. What I want to tell you is that the strict distinction between IaaS, PAAs, and SaaS is not secondary. Why do you say so, in the next article, I will elaborate, quiet please pay attention!

Iv. Collaboration as a service (CaaS): The fourth service provided by cloud computing

Less than a time ago, it was thought that individual contributions played a decisive role in the collective of human society, such as in science and technology, physicist Rutherford, Danish physicist Bohr, and Einstein all proved the importance of the individual. Today, however, it is difficult to say the name of a scientist in the European Commission for Nuclear Research, the body that recently announced the discovery of the Higgs boson. The success of this organization is due to the perfect collaboration between scientists from all over the world.

The same is true of the economy, and it is far from the time for individuals such as Rockefeller and Vanderbilt to change an industry's development. The development of economy and science and the time of team work together, the team's success requires the seamless collaboration of every member. Most Nobel Prizes are awarded to a team of individuals, and almost every major business innovation is a team effort. I think that in addition to the literature and the individual sports like table tennis, the team is more important than the individual, in fact, it is also the support of writers and athletes behind the team, such as editors, coaches and other personnel, only cast the success of writers and table tennis players. From this perspective, it is not difficult to understand why teamwork is an important quality that any individual undertakes in business.

Since it has proven the importance of teamwork, what are the elements of team success? The complementarity of each person in the team is essential, and equally important is their ability to communicate quickly and efficiently. Cross-regional collaboration among team members is important as companies or organizations have branches all over the world. Cloud communication is the best way to achieve collaboration across geographies.

This led to the advent of the concept of "collaborative cloud", in a collaborative cloud environment, using cloud technology, each participant can effectively set up a communication group based on the permissions granted by the administrator, and use various information delivery methods to enhance communication efficiency. According to the cloud services that cloud computing already has: SaaS, PaaS and IaaS, we make this fourth cloud service "collaboration as a Service" (CaaS).

The ability of cloud services to be accessible from anywhere with a variety of smart devices makes collaboration-as-a-service infinitely flexible, which traditional IT services cannot. In the cloud, knowledge and information sharing and decision making are fast and low cost. Avaya, the world's number one provider of cloud collaboration solutions, is helping companies effectively leverage cloud computing to achieve more perfect collaboration goals. From email to phone, east to social media, from chat to video conferencing, every form of communication will have a better effect in the cloud.

In the previous article we discussed in detail the three major business models of cloud computing: SaaS, PaaS, IaaS. After understanding the basic concepts of SaaS, PAAs and IaaS, this article will further discuss the relevant topics, and give some practical suggestions for your reference. If you don't yet know what SaaS, PAAs, IaaS is, see: Cloud Computing: SaaS, PAAs, IaaS are not mysterious (i).

As we have mentioned earlier, the distinction between SaaS, PaaS, and IaaS is a secondary priority. So, why do you say that? Because these three models are involved in outsourcing load, personnel expenditure management, server and network hardware and software maintenance issues. At a higher level, SaaS, PaaS, and IaaS are all designed to solve users ' problems and serve their business. They are, for example, trying to reduce IT infrastructure costs for users, maximize the economic benefits of IT resources, and provide powerful scalability.

For CIOs and business executives, SaaS and PAAs are all tools to serve your business. How to use these tools to better serve the enterprise is the most important. For cloud computing, the author suggests that no matter what the business is, no matter what the type of investment, a standard process must be established. The following is the author's specific recommendations, the sun out for everyone's reference.

First, before starting a specific business, the most important thing is to build a business process model. A scientific method is used to calculate how the new investment will affect the business and the detailed financial budget.

Second, when considering the use of cloud computing services, you have to consider your network needs, and you need to know in detail how much of your data is going to be transferred. You need to know clearly what the service you are running requires for your network. It is very important that it determines the final effect of the business.

Thirdly, security is another important factor that cannot be ignored. You need to know your security needs and choose a reasonable cloud service provider to follow these security standards.

Finally, any new development and changes are risky, before you change the platform and services, you must do a comprehensive test of the new solution, to confirm that the new solution can be stable operation before making greater decisions and investment.

If the services you want to run in a cloud computing platform are business-critical, you must be cautious when choosing a cloud service provider. You take a comprehensive look at it, including organizational forms, business continuity, asset liability and partnerships.

Six, in the actual use of cloud computing services, can not fully believe that the supplier said. You should always be awake and judge their professionalism and authenticity correctly. Continuously observe and evaluate their service patterns and overall capabilities. And a high degree of attention to their services in other enterprises to apply records, in order to be able to identify problems in time, adjust services.

Finally, and most importantly, you should focus on ongoing support for selected cloud computing services and applications. For example, most SaaS application services are sold in subscription mode, which is a very good thing for users. Because this model means that the supplier must provide continuous service support.

The above proposals represent only personal views, and it is not possible to take into account all problems due to limitations of their own knowledge and abilities. Just hope that these things will give some advice to those who want to know about cloud computing or are sourcing cloud computing services. In the following articles, I will also discuss the details of cloud computing, so stay tuned. For more information, see Operating and value-added cloud channels .
