There are three key technologies in cloud computing:
⑴ Virtualization technology: Cloud computing virtualization technology is different from traditional single virtualization. It covers the entire IT architecture, including resources, networks, applications and desktops. Its advantage lies in the ability to isolate all hardware devices, software applications and data, break the boundaries between hardware configuration, software deployment and data distribution, realize dynamic IT architecture, realize centralized resource management, enable applications to dynamically use virtual resources and physical resources, and improve the system's ability to adapt to needs and environment.
For information system simulation, the application significance of cloud computing virtualization technology is not only to improve resource utilization and reduce costs, but also to provide powerful computing power. As we all know, an information system simulation system is a complex system with a large amount of computing. The computing power has a great impact on the system's operating efficiency, accuracy and reliability. Virtualization technology can integrate a large number of dispersed and underutilized computing power into high-load computing computers or servers to realize unified scheduling and use of resources across the network, thereby achieving high efficiency in multiple calculations such as storage, transmission, and computing.
⑵Distributed resource management technology: In most cases, the information system simulation system will be in a multi-node concurrent execution environment. To ensure the correctness of the system state, the consistency of distributed data must be ensured. In order to solve the problem of distribution consistency, many companies and researchers in the computer industry have proposed various protocols, which are some rules that need to be followed. That is to say, before the emergence of cloud computing, solving the problem of distribution consistency was based on many protocols. However, for large-scale and even super-large distributed systems, it is impossible to ensure that each subsystem and subsystem use the same protocol, and the problem of distribution consistency cannot be ensured. Distributed resource management technology in cloud computing has successfully solved this problem. Google's Chubby is the most famous distributed resource management system. This system implements the Chubby service lock mechanism, so that the solution to the distribution consistency problem no longer only depends on one protocol or an algorithm, but has a unified service.
⑶ Parallel programming technology: Cloud computing adopts a parallel programming model. In parallel programming mode, details such as concurrent processing, fault tolerance, data distribution, load balancing, etc. are abstracted into a function library. Through a unified interface, large-scale computing tasks of users are automatically executed concurrently and distributed, that is, a task is automatically divided into multiple subtasks and process massive data in parallel.
For the programming of complex systems such as information system simulation, the parallel programming model is a disruptive revolution. It has developed on a series of outstanding achievements such as network computing, so it fully reflects the service-oriented architecture (SOA) technology. It can be foreseen that if this parallel programming model is introduced into the field of information system simulation, it will definitely bring about leapfrog advances in the construction of information system simulation software.
The future development of artificial intelligence, big data, cloud computing and the Internet of Things is worthy of attention, and they are all cutting-edge industries.
