In the digital era, cloud computing has become an important part of enterprise IT architecture. It provides flexible, scalable and cost-effective computing resources to help enterprises achieve digital transformation, innovate business models and improve competitiveness. This article will introduce the concepts, advantages, and applications of cloud computing, as well as how to successfully adopt cloud computing technology in your enterprise.
2. Overview of cloud computing
1. Source of cloud computing
The term Cloud Computing comes from Google, and the earliest cloud computing product comes from Amazon. Interestingly, when Google officially proposed the term cloud computing in 2006, Amazon's cloud computing product AWS (Amazon Web Service) had been officially operational for almost 4 years. Therefore, some people believe that Google's greatest contribution to cloud computing is to give it a good name, and Amazon is the real pioneer of cloud computing.
2. The concept of cloud computing
Cloud computing is a new term, but not a new concept. The concept of cloud computing has been around since the birth of the Internet. A long time ago, people began to purchase server storage space, then upload files to the server storage space for storage, and then download the files from the server storage space when needed. This is not fundamentally different from Baidu Cloud's model. They just simplify this series of operations.
3. Definition of cloud computing
The Cloud represents the Internet. Through the computing power of the network, instead of using the software you originally installed on your own computer, or replacing the original action of storing data on your own hard drive, you instead do it through the network. Various tasks are performed and archives are stored on the network, which is a huge virtual space. We store data in servers on the Internet through the network services we use, browse the web pages of these services through browsers, and use the interfaces above to perform various calculations and work.
4. Characteristics of cloud computing
In my opinion, the advantages of cloud computing are nothing more than the keywords that often appear in a large amount of existing data: ultra-large scale, virtualization, high reliability, high versatility, high scalability, on-demand services, and extremely cheap.
To put it simply, cloud computing can "turn waste into treasure" and provide us with "high-quality and low-cost" computing resources.
Cloud computing’s ability to “turn waste into treasure”. Theoretically, cloud computing can make full use of resources without increasing resources, and fully utilize servers with original utilization rates of only 20% or 30% to 70% or 80%! Cloud computing can make IT facilities faster and more efficient at the same cost.
As far as "good quality and low price" is concerned, I think the importance of cloud computing can be understood from life examples.
For example, an iron plate can bake 3 cakes at a time, and each cake needs to be baked for 2 minutes on both sides before it is cooked. What is the most time-saving method to bake 4 cakes without adding an additional iron plate?
People's thinking is often to put 3 pieces of cake on the iron plate, bake one side, turn it over, and bake the second side, which takes 4 minutes; then, put the fourth piece of cake on the iron plate, and cook both sides. , and another 4 minutes, a total of 8 minutes. In fact, this method wastes iron plate resources. Not only is the iron plate wasted, but also gas, time, and efficiency are wasted.
Is there any way to save time? Look at this method: bake the first three cakes on the first side for 2 minutes, turn over two of the cakes, remove the third cake, put the fourth cake on, continue to bake for another 2 minutes, these 4 minutes It passed, and the result was that the first two pieces were already cooked. Turn the fourth piece over, and put the third piece, uncooked side down, on the iron plate to continue baking. After 2 minutes, the four pieces of cake were fully cooked, a total of It took 6 minutes! Save 25% of time!
If we go one step further and allow every household to bake pancakes at the same place instead of buying tools like iron plates, each family will not need to build or maintain these tools, but focus on "how to bake good pancakes." More importantly, the labor cost and consumption cost of making pancakes will be greatly reduced, and the quality of the pancakes will be more guaranteed. Isn't it wonderful?
3. How cloud computing changes human beings
With the development of cloud computing, it will change human beings just as its concept says: "Cloud computing will become a public resource like water and electricity. People can use it freely anytime, anywhere, at any time." There is a fee required. "What specific impact will cloud computing have on our lives? Let us talk about the changes in our lives in the era of cloud computing in detail.
1,Reduce household expenses
Nowadays, every family must have one or two computers, iPads, etc. People use these devices for work or life. People's lives have long been inseparable from these devices. However, these electronic devices become obsolete very quickly. People buy new computers for three to five years. As various large-scale application software takes up more hard drive and memory space, the speed becomes extremely slow and they have to be replaced. The equipment that was originally purchased for several thousand yuan could not even be sold for a hundred yuan when it was scrapped. These purchase expenses are also a large expense for a family. Entering the cloud era, people only need to connect to the Internet to access their own application software, continue to work and handle daily chores. All resources are placed in the cloud. People will not rely on a specific computer. People only need to put A large monitor and a terminal that can access the network are all you need, and you don’t have to worry about these equipment components becoming obsolete. In fact, a large virtual computer is built in the cloud, and all programs and resources are placed on it, which can be accessed through the terminal at home. In fact, it has now been realized in many technology companies. All working personnel do not have their own computers. They only have a monitor and access terminal. They access the cloud platform through the terminal. All work materials are placed on the cloud platform, which not only saves Office space also reduces the company's overall consumption of office equipment resources.
2. Maintenance-free
Since all data is stored in the cloud and programs are run in the cloud, people no longer need to consider security issues, junk information cleanup, software upgrades, etc. In the background of cloud computing, there are professional cloud service team personnel maintaining and managing it. . This is just like the water pipes are managed by the water company, and the electricity lines are managed by the power supply company. As the saying goes, "specialization in the industry" requires professional personnel to manage it, which is much better than people doing it themselves. We usually encounter problems of this kind when using computers. After using up the three axes of uninstalling, restarting, and reinstalling the system, if there are still problems, they will basically be gone. You will have to find someone to repair them, and you will have to pay a lot of money for repairs. cost. In addition, if the computer's security software is not updated in time, it will be vulnerable to attacks, and the home computer itself is relatively weak in preventing attacks. These problems can be well solved through cloud computing. Cloud computing not only separates application development from basic design and maintenance, but also reduces people's time and energy in maintaining terminal equipment. People no longer have to worry about problems with their computers.
3. No longer dependent on a specific computer
All the resources that people need to access are placed on the cloud, and local computers are no longer needed, which effectively avoids single points of failure. Of course, it is inevitable that the equipment of companies providing cloud services will have failures of one kind or another. However, cloud computing has good redundancy technology to ensure that data resources are not lost in the event of a failure. Even if data is lost, the company providing cloud services is obliged to pay high compensation to make up for people's losses. If people put all their data on their own computers, if the computer malfunctions, all the data may be lost and cannot be retrieved. This will only make you feel unlucky and you cannot go to the computer manufacturer. Although you can prepare a few more computers at home fordata backup, the cost will be very high, and computers will become obsolete very quickly. After two years Every year several computers have to be eliminated at the same time, which is very wasteful. As the saying goes, "Don't put all your eggs in one basket", it is to prevent the basket from being broken and all the eggs to be broken. Cloud computing provides people with virtual cloud resources, equipment failure at the physical layer, and virtual resource layer. It is impossible to detect it at all. It is equivalent to having countless backups and the reliability is greatly improved.
4. Entering the era of Internet of Everything
Cloud computing breaks people's inherent physical operations and geographical restrictions, realizes the migration from computers to mobile phones, cars, and home appliances, connects all electronic devices to the network, and can accept remote control. This is the original intention of the Internet of Things design. Cloud computing is one of the important core technologies for the implementation of the Internet of Things. Through the integration of the cloud and the full utilization of resources, people can enjoy this convenient service at a low cost. For example: in the future, we may be able to start the car and drive out of the garage before going out, and turn on the heating at home before returning home. By the time we get home, the home is already warm, and it will cost a lot of money to fly to the airport on the way. How long it will take can be predicted in advance to avoid being late or arriving at the airport too early. A series of applications such as this will definitely become a reality in the future. Cloud computing will bring earth-shaking changes to our lives. There is nothing we can't imagine but nothing we can't do.
5. Pay on demand
Pay-as-you-go is the most important attribute of cloud computing. To open broadband at home, we often have to pay in advance. But during the use period, even if it is not used for a day, the fee has been paid. Even if it is used every day, it is still the same fee. This seems unfair. If you purchase traffic on a monthly basis, you may not have enough traffic at the end of the month but will have to spend more money. The application of cloud computing can solve these problems. People can expand resources on demand, pay according to actual usage, pay more when they use more, and pay less when they use less. There is no need to buy a lot of equipment for one-time tasks or rare load conditions, and it is the same as home water, electricity and natural gas. Similarly, the valve can be used when it is opened, and billing stops immediately when it is closed.
Cloud computing has changed the way people live and work, providing endless possibilities. Cloud computing built on the network has brought people a lot of convenience and opened up a happy cloud life era for people in the future.
4. Conclusion
The widespread application of cloud computing has profoundly changed human lifestyles and social development. By providing powerful computing and storage capabilities, cloud computing has brought great innovation and convenience to many fields such as education, medical care, work, entertainment, and social interaction. With the continuous development and popularization of cloud computing technology, we can look forward to more new application scenarios and changes, creating a better future for mankind.
