This article mainly introduces what levels of cloud computing architecture have, which has certain reference value, and friends who need it can refer to it. I hope you will have a lot of success after reading this article. Let's take a look at it together.

Cloud computing architecture is divided into three layers: infrastructure layer, platform layer and software service layer. The purpose of cloud computing is to organize and integrate shared software or hardware resources and information through network-based computing, and provide them to computers or other systems on demand.

Introduction:

Cloud computing architecture is divided into three layers: infrastructure layer, platform layer and software service layer. The purpose of cloud computing is to organize and integrate shared software or hardware resources and information through network-based computing, and provide them to computers or other systems on demand.

Details:

Cloud computing is the product of the convergence of traditional computer and network technologies such as grid computing, distributed computing, parallel computing, utility technology, network storage, virtualization and Load Balancer. Its purpose is to organize and integrate shared software/hardware resources and information through network-based computing and provide them to computers and other systems on demand.

Generally speaking, the cloud architecture is divided into three layers: infrastructure layer, platform layer and software service layer. The corresponding names are IaaS, PaaS and SaaS. IaaS, Infrastructure as a Service, Chinese name for Infrastructure as a Service.

IaaS mainly includes computer servers, communication equipment, storage equipment, etc., IT infrastructure services such as computing capacity, storage capacity or network capacity that can be provided to users on demand, that is, services that can be provided at the infrastructure level. The core of IaaS mature application lies in virtualization technology. Through virtualization technology, various computing devices can be virtualized into computing resources in virtual resource pools, storage devices can be virtualized into storage resources in virtual resource pools, and network devices can be virtualized into network resources in virtual resource pools. When a user orders these resources, the data center manager packages the share of the order directly to the user, thus implementing IaaS.

PaaS, Platform as a Service, Chinese name is Platform as a Service. If you look at it from the perspective of "hardware + operating system/development tools + application software" in traditional computer architecture, then the platform layer of cloud computing should provide functions similar to operating system and development tools. In fact, PaaS is positioned to provide users with a complete set of supporting platforms for developing, running and operating application software through the Internet. Just as in PC software development mode, programmers might use development tools to develop and deploy applications on a computer with Windows or Linux operating systems. Microsoft's Windows Azure and Google's GAE are two of the most well-known PaaS platforms.

SaaS, Software as a Service. Simply put, it is a software application model that provides software services through the Internet. In this mode, users do not need to spend a lot of investment in hardware, software and development team construction, only need to pay a certain rental fee, you can enjoy the corresponding services through the Internet, and the maintenance of the entire system is also responsible for the manufacturer.

Thank you for reading this article carefully. I hope that Xiaobian can share what levels of cloud computing architecture are helpful to everyone. At the same time, I hope that everyone will support more, pay attention to the industry information channel, find out if you encounter problems, and find detailed solutions waiting for you to learn!
