Lesson Goal:
Understand the basics of cloud computing, its advantages, and its impact on our daily digital interactions.
Cloud computing, a term that has become ubiquitous in the digital world, refers to the delivery of various services through the Internet. These resources include tools and applications like data storage, servers, databases, networking, and software.
Understanding the Basics: Cloud computing means storing and accessing data and programs over the Internet instead of your computer’s hard drive. The “cloud” is a metaphor for the Internet. When you store data on or run programs from the hard drive, that’s called local storage and computing. Everything you need is physically close to you, which means accessing your data is fast and easy, for that one computer, or others on the local network. But when you’re using the cloud, your data and applications are stored on servers at a remote location, which you access via the internet.
Types of Cloud Services:
- Infrastructure as a Service (IaaS): Provides basic infrastructure like servers, storage, and networking resources.
- Platform as a Service (PaaS): Offers a development environment, including tools for building and hosting web applications.
- Software as a Service (SaaS): Delivers software applications over the Internet, typically on a subscription basis.
Advantages of Cloud Computing:
- Cost-Efficiency: Reduces the cost of managing and maintaining IT systems.
- Scalability: Easily scale up or down your operation and storage needs.
- Performance: Cloud computing services run on a worldwide network of secure data centers, which are regularly upgraded for fast and efficient computing performance.
- Reliability: Data backup, disaster recovery, and data replication are easier and less expensive.
How it Affects Us Daily:
- Data Storage: Services like Google Drive or iCloud store our personal data.
- Streaming Services: Netflix and Spotify leverage cloud computing for their streaming services.
- Email Services: Gmail and Outlook are examples of cloud-based email services.
- Social Media: Platforms like Facebook and Instagram store massive amounts of data in the cloud.
Summary: Cloud computing is the delivery of computing services over the Internet, enabling faster innovation, flexible resources, and economies of scale. It has transformed the way we store, access, and manage data, offering scalability, reliability, and cost-efficiency.
