The theme of cloud technology is to explore its possible application modes in the printing industry in the future. It mainly describes the development of cloud technology after DTP digital technology, which will become the most important mode of printing information generation. . The first paragraph explains the meaning of cloud technology. The second paragraph is based on the configuration model of cloud technology, the service characteristics of cloud computing, and the level of service. The third paragraph takes cloud technology and print production as the sub-topics to describe its huge information usage group for the printing industry, great benefits for the printing industry, and room for development. The fourth paragraph explains that cloud technology and EP need to use multiple software to embed audio and video, animation, which has a lot of added value to the printing industry.
At the beginning of the invention of the computer, because the host, storage and output and other components are very expensive, they are all based on the master-slave architecture. The individual operating terminals only have a keyboard and screen interface, and the data that can be stored is also very limited, usually less than 1MB. After the development of the personal computer, because of its greatly enhanced computing power, the storage capacity has grown from 10MB to hundreds or even thousands of GB now, and the use of regional cable networks seems to have met the needs of most printing systems. 1. Output before printing to the printing plate, and even transmit through the local network in the factory for digital printing and output. But when going to wired Internet, wireless Internet, and systems with their own systems, unless there are T1 and T3 lines, the current external transmission speed of ADSL is still seriously insufficient, which has a great impact on the timeliness, and sometimes it is caused by a sudden drop in rate Big troubles.
When it came to the era of cloud technology, the structure of computer operations reverted to the early master-slave architecture, as the main "cloud" of tens of thousands, millions of calculations and huge storage space, plus the extremely wide bandwidth between each cloud and the cloud The ability to transfer files, whether you have a cloud or a public cloud, will be very smooth and fast in the cloud for manuscript file acceptance, page editing calculations, file storage to transmission. In addition, the short-volume development of plateless digital printing equipment will change the traditional situation of first printing first, and then using printed materials for short-distance and long-distance distribution, which is time-consuming and labor-intensive. After the method, the burden of shipping logistics and time can be reduced. Moreover, the efficiency of printing, editing, assembling, distributing, and sending to their respective output terminals will be hundreds of times to tens of thousands of times faster than that of the traditional personal computer era, and users only need to operate on a simple terminal due to work instructions. The amount of information is very small, and it is easy to transmit. The computing power of cloud technology is tens of thousands of times before. The storage capacity is too large to estimate, and the user only pays when using it. There is no need to buy a high-energy computer. Reducing huge depreciation expenses, compared with e-books and e-reading tools invading the printing market, cloud technology can enable the printing industry to achieve faster transmission, higher efficiency, and lower cost of first transmission after printing, producing stable and long-lasting printing The finished paper products create a new competitive opportunity, which will be the most important digital technology change after printing digitization from DTP to CTP.
1. What is cloud technology
The interpretation of "cloud" in the Mandarin dictionary is "water vapor meets cold, condenses into fine water droplets, and suspends in the air." This mass can be seen but seems intangible because it is suspended in the air. Now, what we mean by the "cloud" in the computer world is a metaphor for the Internet, especially for wireless network reception and transmission.
The so-called cloud technology refers to a new way of receiving, calculating, storing and disseminating information, which is operated by the server host, and the user only needs to use very simple instructions and screen display, and the other is from thousands to tens of thousands. Tens of thousands of computing and storage, coupled with a very large network bandwidth, do a variety of high-efficiency transmission between the cloud and the cloud, or pass it to the output for application. Cloud computing and storage are only paid when used, even the software The lease method can greatly increase the utilization rate, reduce the use cost, and can also ensure information security.
"End" means that both ends of everything are called. For the Internet, there are a service end and a user end. Provide service terminals such as Chunghwa Telecom, IBM or other related companies. They provide high-performance computing functions, a large amount of storage space, and ultra-fast file transmission. They provide music, video, or document information to count or time charges. At the user end, it can also be rented or debited to make the business run smoothly. However, information fluency, computational stability, and system security will all be important prerequisites. In this way, the equipment at the user end becomes very simple and low-cost. How much does it cost to calculate, store, and transmit on the cloud? Unless you own a cloud, the cost will be higher and the output bandwidth will be equivalent. Big.
The user side can obtain, process or store data from the super computer on the server side through wired or wireless Internet. In addition to file files, it also includes various application software. In this way, the computer on the user side can be very simple, as long as there is a keyboard , Screen, a small amount of storage space and wired or wireless Internet devices, you can use the cloud to do various operations, so the cloud is the main body, the end is the operating interface. In this way, as long as there is an Internet place in the world, you can do remote creation, editing, storage and other actions. It has a huge impact on our personal lives and businesses.
"Cloud technology" is the science and technology that utilizes the functions of Cloud Computing. This technology uses extremely broadband networks in combination with numerous computer resources to provide services, and according to the number of needs, it is convenient and flexible to meet users' needs. demand. It is a huge change after the master-slave architecture of the mainframe computer from the client to the server in the 1980s, and then transformed into a personal computer. In other words, it is a cloud computer with huge storage space and transmission bandwidth to provide an IT service based on the Internet. In essence, he is a new application of distributed computing. Its most basic concept is to automatically split the huge computing processing program into countless smaller subprograms through the Internet, and then hand over to more The huge system composed of the local server, after searching and computing analysis, then leave the processing information on the cloud server, and only return the result to the user for modification or confirmation. Through this technology, network service providers can process tens of millions or even billions of information within seconds, achieving the same powerful and powerful network calculation service and document storage and transmission effect as "supercomputer". There is no need to buy and maintain huge information and network equipment around you.
Second, the classification of cloud technology
As of 2009, most of the cloud computing infrastructure is composed of trusted services delivered through the data center and different levels of virtualization technology built on the server. People can use these services wherever they have network infrastructure. "Cloud" usually represents a single access point to the computing needs of all users. People usually hope that commercialized products can meet the requirements of Quality of Service, and generally provide service level agreements. Open standards are crucial to the development of cloud computing, and open software has provided the foundation for many cloud computing projects.
(1) The configuration model of cloud computing is divided into the following four types:
â‘ Private cloud-only a cloud owned and used by an organization or printing company. The location of the cloud may or may not be the location owned by the organization, and the management of the cloud may also be outsourced.
â‘¡Community cloud ?? Cloud computing services shared by organizations with common characteristics, such as government cloud to provide services to government agencies, or organizations for special needs, such as the medical cloud established by hospitals, may also establish Taiwan printing Cloud, for all printing and related individuals or groups.
â‘¢Public Cloud ?? This type of cloud computing service is constructed and provided by an external data center, and it does not set limits on customers.
â‘£Hybrid cloud ?? A cloud computing service that combines the features of at least two of the above three architectures.
(2) Cloud computing services usually have the following characteristics:
â‘ Multi-user ?? The construction required to support cloud computing must also have a corresponding economic scale. Therefore, multiple users will be one of the important features of many cloud service providers.
â‘¡Flexibility and flexibility ?? Users can enjoy flexible price calculation and payment methods according to their needs, while also being able to flexibly use (increase or decrease) computing resources to match actual usage conditions.
â‘¢A wide range of access platforms-Whether users use general computers or mobile phones and other electronic communication devices, they can access the services provided by cloud computing through the network.
(3) Cloud services include the following three levels:
â‘ The upper layer ?? Software Service (Softwareasa Service), software developers around the world can participate, so that it can break the monopoly of the big factories in the past, everyone can freely use their creativity to provide a variety of software services, Charge only when it is useful to avoid the intrusion of piracy.
â‘¡Middle-level platform service (Platformasa Service), with participation of Google, Microsoft, Apple, Yahoo and other companies, provides a program development platform and an operating system platform, allowing developers to write programs and services through the Internet, and general consumers can also Run the program on it to do file reception, page editing or layout integration.
â‘¢ The lower layer-infrastructure service (Infrastructureasa Service), which involves companies such as Inventec, IBM, Dell, Sun, HP, Amazon and other companies, can integrate basic equipment (such as IT systems, databases, etc.) and separate them like hotels Different rooms can be rented by enterprises. You can pay as much as you want. You can also provide targeted private clouds and community clouds, such as the Taiwan Printing Cloud.
With cloud services, it is possible to improve the current enterprise's embarrassment of using IT equipment with a large amount of money to cover the computer room architecture, but the utilization rate is less than 15%. Allows nearly 80% of the original resources to be shared with others on the cloud. In addition, just maintaining the existing functions can save 70% of the total IT budget, which does not include personnel costs and software upgrades. Therefore, if the cloud computing technology is used instead, the equipment room maintenance, network management and software upgrade will be handed over to the cloud for processing. According to the research report of McKinsey & Company, a company with 200 employees will only use software if it uses cloud technology. The cost can be at least 30% less than that of the present, and if there is a printing community cloud, file transmission in the future will be very convenient. After the color reproduction management specifications are institutionalized, a good work distribution and supporting printing system will be formed.
