Here are the top 7 AWS services that are widely used for building, deploying, and managing cloud-based applications:
- Amazon EC2 (Elastic Compute Cloud)
What it does: Amazon EC2 provides scalable virtual servers, called instances, to run applications in the cloud. You can choose the instance type, configure security settings, and scale the capacity according to your needs.
Why it’s popular: EC2 is a fundamental service for running web servers, databases, or any application requiring compute resources. It offers full control over the operating system and configuration.
Use case: Hosting websites, running big data workloads, machine learning models, or web applications.
- Amazon S3 (Simple Storage Service)
What it does: Amazon S3 is an object storage service that provides scalable, high-speed, and secure storage for data. It is often used for storing and retrieving large amounts of data like images, videos, backups, and logs.
Why it’s popular: S3 is highly durable (99.999999999% durability) and scalable. It’s ideal for developers, enterprises, and startups to store files and data.
Use case: Storing backups, media files, static websites, or large data archives.
- AWS Lambda
What it does: AWS Lambda is a serverless computing service that lets you run code without provisioning or managing servers. You only pay for the time your code executes.
Why it’s popular: It automatically scales, is cost-efficient, and is event-driven, making it great for running small, isolated pieces of code in response to events like file uploads, database changes, or HTTP requests.
Use case: Automating tasks, backend for microservices, processing uploaded files in real-time, and triggering functions based on events.
- Amazon RDS (Relational Database Service)
What it does: Amazon RDS is a managed relational database service that supports several database engines, including MySQL, PostgreSQL, MariaDB, Oracle, and Microsoft SQL Server.
Why it’s popular: RDS handles routine database tasks such as backups, patch management, and scaling, allowing you to focus on your application instead of database maintenance.
Use case: Running scalable relational databases for web applications, CRM systems, and e-commerce platforms.
- Amazon CloudFront
What it does: Amazon CloudFront is a content delivery network (CDN) that speeds up the delivery of your content (e.g., HTML, CSS, JavaScript, images, videos) by caching it at locations closer to the end users.
Why it’s popular: CloudFront helps reduce latency and improves the user experience by distributing content to multiple locations around the world (edge locations).
Use case: Accelerating the delivery of web applications, media streaming, and APIs.
- Amazon VPC (Virtual Private Cloud)
What it does: Amazon VPC allows you to create a logically isolated network in the AWS cloud. It gives you full control over your virtual networking environment, including IP address ranges, subnets, and route tables.
Why it’s popular: VPC provides a secure and scalable environment for running your applications and hosting sensitive data with strict access controls.
Use case: Hosting a private network for applications, creating secure environments for databases, and implementing hybrid cloud infrastructures.
- AWS IAM (Identity and Access Management)
What it does: AWS IAM allows you to manage access to AWS services and resources securely. It enables you to create and manage AWS users, groups, roles, and permissions.
Why it’s popular: IAM is critical for ensuring security in the cloud. It allows fine-grained control over who can access your resources and what actions they can perform.
Use case: Defining user roles, managing permissions, and ensuring that only authorized users can access specific AWS resources.
Why These Services Are popular?
These services form the backbone of most cloud-based architectures because they are highly scalable, flexible, and integrate well with other AWS services. Whether you're building a simple website or a complex distributed application, these services will likely be part of your AWS infrastructure, handling compute, storage, networking, security, and content delivery needs.

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.
