ComputingThe definition of cloud computingCloud computing is a computing service model that provides scalable,elastic,and on-demand services through the network.SummaryCloud computing is a model that provides computing resources(such as servers,storage devices,and applications)as services to users through the Internet.Users can obtain the required computing resources according to their needs,without the need for large-scale investments on local devices.Detailed descriptionThe characteristics of cloud computingSummary:Cloud computing has the characteristics of virtualization,elasticity and scalability,on-demand payment,and global distribution.Detailed description:Virtualization is the core technology of cloud computing,which allows the virtualization of physical hardware resources into multiple virtual resources,achieving resource sharing and flexible scheduling.Elastic scalability refers to the ability of computing resources to dynamically scale according to user needs,meeting the needs of applications of different scales.On demand payment allows users to pay based on actual usage,avoiding waste and reducing costs.Global distribution emphasizes that cloud computing services can be provided globally without geographical limitations.The Development History of Cloud ComputingSummary:The development process of cloud computing includes three stages:technological origin,initial development,and widespread application.Detailed description:The concept and technology of cloud computing originated in the 1960s,when computer scientists proposed the idea of sharing and virtualization of computing resources.In the late 1990s,with the popularization of the Internet and technological progress,companies such as Amazon began to provide simple cloud services.After entering the 21st century,with the continuous improvement of cloud computing technology and the expansion of application scenarios,cloud computing has begun to be widely applied in various fields,becoming a mainstream computing mode.02Cloud computing technology Virtualization technology is a technique that virtualizes physical hardware resources into multiple logical resources,allowing multiple operating systems to run simultaneously on a physical server,improving server utilization.By using virtualization software(such as VMware,VirtualBox,etc.),physical hardware resources(such as CPU,memory,storage,etc.)are virtualized into multiple logical resources,each of which can run an operating system.Virtualization technology is widely used in fields such as cloud computing,big data,and enterprise level applications,which can reduce hardware costs,improve resource utilization,and simplify management.DefinitionImplementation methodApplication scenarioVirtualization technology Distributed computing is a technology that decomposes a large computing task into multiple small tasks and performs calculations simultaneously on multiple computing nodes,ultimately summarizing the calculation results to obtain the final result.Decompose a large computing task into multiple small tasks using distributed computing frameworks such as Hadoop and Spark,and perform calculations simultaneously on multiple computing nodes,with each computing node only processing a portion of the data.Distributed computing is widely used in fields such as big data processing,machine learning,scientific computing,etc.It can process large-scale data,improve computing efficiency,and reduce computing costs.DefinitionImplementation methodApplication scenarioDistributed computing Cloud storage is a technology that stores data in the cloud,allowing users to access and share data anytime,anywhere through the network.Through cloud storage services provided by cloud storage service providers(such as Amazon S3,Alibaba Cloud OSS,etc.),users can upload data to the cloud for storage and management,and access and share data anytime and anywhere through the network.Cloud storage is widely used in enterprise level applications,personal file storage,media content distribution,and other fields,which can improve data security,scalability,and reliability.DefinitionImplementation methodApplication scenarioCloud storage technologyDefinition Automated management is a technology that completes traditional management tasks through automated tools,which can improve management efficiency and quality.Implementation method Automatically complete management tasks through automated management tools such as Ansible,Chef,etc.,such as deploying applications,configuring network devices,monitoring system performance,etc.Application scenario Automated management is widely used in enterprise level applications,cloud computing,and other fields,which can improve management efficiency and quality,and reduce management costs.Automated management03Cloud computing applicationsERP systems Implementing ERP systems on the cloud can help
