The full name of VPS stands for Virtual Private Server; VPS technology is a high-quality service that divides a server into multiple virtual private servers; the technology to realize VPS is divided into container technology and virtualization technology.
#The operating environment of this article: linux5.9.8 system, Dell G3 computer.
1: What is VPS
VPS is a virtual private server, which divides the server into multiple virtual servers and shares one server with multiple users , but a VPS, is set up to be able to use almost the same freedom and performance as a dedicated server.
2: How VPS works and the difference from shared servers
The biggest difference between VPS and shared servers is the freedom and performance of the available servers. We think there are many people using rented servers equal to shared servers, here we will explain the difference between VPS and shared servers in detail.
VPS virtual machines build multiple servers in one physical server. Unlike shared servers, the guest operating system is prepared for each user based on the host operating system. Basically, each customer operation will not interfere with each other. Therefore, like a shared server, it will basically not cause trouble or heavy operations due to the use of other users. However, for memory and CPU, unlike a shared server, the performance of the guest virtual machine operating system is safe, so it is more suitable to use than shared servers. More load on the server. In addition, another difference from a shared server is that you can freely operate software on the client operating system.
Three: The difference between a dedicated server and a VPS
A dedicated server is a server that can fully use a single physical server, even a VPS virtual private server. A physical server will be dedicated. Therefore, dedicated servers are more compatible with performance and load. Additionally, if that physical server fails, all VPS users using that server will be affected.
For VPS, it becomes a form of sharing between two or more people. If used by many people, the response may not be very good. On the contrary, VPS is much cheaper than a dedicated server.
4: Advantages and Disadvantages of VPS
Dedicated servers are relatively cheaper, and shared servers have a higher degree of freedom, but the only disadvantage is that All server settings and operations must be completed by the dealer.

React vs. Backend Frameworks: A ComparisonApr 13, 2025 am 12:06 AMReact is a front-end framework for building user interfaces; a back-end framework is used to build server-side applications. React provides componentized and efficient UI updates, and the backend framework provides a complete backend service solution. When choosing a technology stack, project requirements, team skills, and scalability should be considered.
HTML and React: The Relationship Between Markup and ComponentsApr 12, 2025 am 12:03 AMThe relationship between HTML and React is the core of front-end development, and they jointly build the user interface of modern web applications. 1) HTML defines the content structure and semantics, and React builds a dynamic interface through componentization. 2) React components use JSX syntax to embed HTML to achieve intelligent rendering. 3) Component life cycle manages HTML rendering and updates dynamically according to state and attributes. 4) Use components to optimize HTML structure and improve maintainability. 5) Performance optimization includes avoiding unnecessary rendering, using key attributes, and keeping the component single responsibility.
React and the Frontend: Building Interactive ExperiencesApr 11, 2025 am 12:02 AMReact is the preferred tool for building interactive front-end experiences. 1) React simplifies UI development through componentization and virtual DOM. 2) Components are divided into function components and class components. Function components are simpler and class components provide more life cycle methods. 3) The working principle of React relies on virtual DOM and reconciliation algorithm to improve performance. 4) State management uses useState or this.state, and life cycle methods such as componentDidMount are used for specific logic. 5) Basic usage includes creating components and managing state, and advanced usage involves custom hooks and performance optimization. 6) Common errors include improper status updates and performance issues, debugging skills include using ReactDevTools and Excellent
React and the Frontend Stack: The Tools and TechnologiesApr 10, 2025 am 09:34 AMReact is a JavaScript library for building user interfaces, with its core components and state management. 1) Simplify UI development through componentization and state management. 2) The working principle includes reconciliation and rendering, and optimization can be implemented through React.memo and useMemo. 3) The basic usage is to create and render components, and the advanced usage includes using Hooks and ContextAPI. 4) Common errors such as improper status update, you can use ReactDevTools to debug. 5) Performance optimization includes using React.memo, virtualization lists and CodeSplitting, and keeping code readable and maintainable is best practice.
React's Role in HTML: Enhancing User ExperienceApr 09, 2025 am 12:11 AMReact combines JSX and HTML to improve user experience. 1) JSX embeds HTML to make development more intuitive. 2) The virtual DOM mechanism optimizes performance and reduces DOM operations. 3) Component-based management UI to improve maintainability. 4) State management and event processing enhance interactivity.
React Components: Creating Reusable Elements in HTMLApr 08, 2025 pm 05:53 PMReact components can be defined by functions or classes, encapsulating UI logic and accepting input data through props. 1) Define components: Use functions or classes to return React elements. 2) Rendering component: React calls render method or executes function component. 3) Multiplexing components: pass data through props to build a complex UI. The lifecycle approach of components allows logic to be executed at different stages, improving development efficiency and code maintainability.
React Strict Mode PurposeApr 02, 2025 pm 05:51 PMReact Strict Mode is a development tool that highlights potential issues in React applications by activating additional checks and warnings. It helps identify legacy code, unsafe lifecycles, and side effects, encouraging modern React practices.
React Fragments UsageApr 02, 2025 pm 05:50 PMReact Fragments allow grouping children without extra DOM nodes, enhancing structure, performance, and accessibility. They support keys for efficient list rendering.
