Cloud Technology: How Does It Affect Our Daily Lives?

What is Cloud?

Cloud is a technology that allows you to store and access data. For example, have you ever used Google Drive or Naver Cloud? These allow you to save and open files anytime, anywhere, through cloud services.

In the past, photos and documents were stored on computers or USB drives, but with the cloud, you can view and use data from any device with an internet connection. Files worked on at home can also be opened at the office or a cafe.

What is Cloud Computing?

Cloud computing is a method of providing computing resources over the internet. This means we no longer need to purchase expensive computers or servers. We can pay only for what we need.

Advantages of Cloud Computing

• Scalability: For example, if you suddenly have to run a website with many visitors, you'll need more server resources. Cloud computing allows you to flexibly increase or decrease resources as needed.
• Cost-effectiveness: You can save money by paying only for what you need, rather than purchasing and managing servers yourself.
• Flexibility: You can easily use various types of software and services. You can introduce new technologies at any time as needed.

What is a Cloud Computer?

A cloud computer refers to a virtual computer provided through cloud services. For example, you can rent virtual computers through Google Cloud or Amazon Web Services (AWS). This allows you to perform necessary computing tasks even without physical computers.

What is Multi-Cloud?

Multi-cloud refers to using multiple cloud services simultaneously. For example, a company might use both AWS and Microsoft Azure.

Advantages of Multi-Cloud

• Stability: If one cloud service has a problem, you can use another service to prevent service interruptions.
• Optimization: You can achieve optimal performance by utilizing the strengths of each cloud service.
• Cost reduction: You can compare the cost structures of each cloud service and make the most economical choice.

Examples of Everyday Cloud Usage

• Photo storage: Storing photos taken with your smartphone in the cloud prevents loss of photos even if your device is damaged or lost.
• Music streaming: Music streaming services like Spotify or Melon use the cloud to provide music to users.
• Remote learning: The cloud can be used to share learning materials and collaborate remotely from school or work.
