Study Notes
Cloud Computing Introduction
- Cloud computing is a way to store and process information on the internet, instead of on a personal computer.
- It allows access to data and applications from any device with an internet connection.
- It uses massive data centers, composed of clusters of servers.
- Data centers often have their own power and cooling systems.
Data Center Characteristics
- Data centers can be the size of a football field.
- They contain hundreds or thousands of clusters of servers.
- They require massive networking, emergency power supplies, and cooling infrastructure.
Data Center Challenges
- Building and maintaining a data center is expensive and requires expertise.
- Scaling up or down a data center is challenging.
Cloud Computing Solutions
- Cloud computing solves the challenges of building and managing data centers.
- It is cheaper to run one large data center than many smaller ones.
- It offers high utilization and a pay-as-you-go model.
- It is scalable, adding more resources within seconds.
Cloud Computing Benefits
- Accessibility: Allows data and programs to be accessible from anywhere with an internet connection.
- Scalability: Can easily grow or shrink to meet needs, similar to a room expanding or contracting.
- Cost-Efficiency: Pays for only the space used, rather than buying and maintaining own storage.
Cloud Computing Examples
- Email: Services like Gmail store emails in the cloud.
- File Storage: Services like Google Drive and Dropbox store files in the cloud.
- Streaming: Services like Netflix and Spotify store movies and music in the cloud.
Cloud Computing Models
- Software as a service (SaaS): Renting software applications that run in the cloud.
- Platform as a service (PaaS): Renting a platform for developing, testing, and deploying applications.
- Infrastructure as a service (IaaS): Renting basic building blocks of computing infrastructure, like servers and storage.
Cloud Computing Model Examples
- SaaS Example: Microsoft 365.
- PaaS Example: Google App Engine
- IaaS Example: Amazon Web Services (AWS) and Microsoft Azure.
