Unlock Cloud Computing: History, Core Concepts, and a Practical Learning Path

Course Overview

U创营 is a cloud‑computing popularization series designed for university students, offering video lectures, illustrated explanations, and hands‑on labs to bridge the gap between theory and practice and help learners acquire basic employable skills.

Course Content

The introductory lesson lays the foundation for the series, presenting the development history of cloud computing, its core products, and typical application scenarios. The instructor also shares effective learning paths and methods.

-1- Cloud Computing Development History

The cloud computing concept was introduced about ten years ago, closely linked to parallel and distributed computing.

March 2006: Amazon launched its first cloud product, S3 (Simple Storage Service).

August 2006: Google announced the term “Cloud Computing” at a product launch.

2009: The first domestic cloud service providers were established; by 2012, numerous cloud startups emerged, marking the start of the cloud era.

According to Gartner’s 2019 report, cloud computing accounted for 10.1% of system architecture in 2019 and is projected to reach 26.5% by 2023, indicating continued growth and deeper penetration.

-2- Why Use Cloud Computing

Focus on Innovation : The platform handles server maintenance and data storage, allowing users to concentrate on their core business.

Elastic Scaling : Unlike traditional self‑built data centers that waste resources, cloud providers offer massive shared resource pools that can be allocated on demand.

Pay‑as‑You‑Go : Most providers charge by the hour, month, or year, so users only pay for the resources they actually consume.

-3- Core Cloud Concepts

Two fundamental concepts are Region and Availability Zone (AZ) . An AZ is a physically independent zone with separate power and network, while a Region consists of multiple AZs within the same geographical area.

Resources in different AZs within the same Region are isolated from each other, using independent power, cooling, and fire protection systems, which enhances risk mitigation.

Cloud Product Panorama

Compute, network, storage, and database services form the basic building blocks of cloud platforms. These products can be combined like Lego bricks to support a wide range of industries.

-4- How to Learn Cloud Computing

Learning Path and Methods:

Start with commonly used products: Cloud Server → EIP → Load Balancer → Object Storage → Database → Cloud Security → AI → Containers …

Combine video learning with hands‑on practice: Use official cloud documentation for systematic study and select scenarios for practical experiments.

Conclusion

Cloud computing has evolved for 13 years and is now in a rapid growth phase. The question is no longer “whether to use the cloud,” but “how to use it effectively.” The U创营 series aims to help learners find the answer.
