Definition

Cloud Computing

The delivery of computing services (servers, storage, databases, networking, software) over the Internet ("the cloud").

Cloud computing has transformed the way organizations manage data, applications, and IT infrastructure.
By leveraging remote servers and virtualized resources , businesses can reduce costs, improve scalability , and enhance collaboration.
However, the shift to cloud computing also introduces challenges related to security, privacy , and control.

Note

Key Terms:

Public Cloud: Cloud services offered by third-party providers to multiple customers over the Internet.
Private Cloud: Cloud infrastructure operated solely for a single organization, either on-premises or hosted by a third party.
Hybrid Cloud: A combination of public and private clouds, allowing data and applications to be shared between them.

Benefits of Cloud Computing

Cost Efficiency

Reduced Capital Expenditure: Organizations no longer need to invest in expensive hardware and infrastructure.
Pay-as-You-Go Model: Cloud providers charge based on usage, allowing businesses to scale resources up or down as needed.

Example

Netflix uses AWS to stream content to millions of users worldwide, scaling resources during peak times and reducing costs during off-peak periods.

Scalability and Flexibility

On-Demand Resources: Cloud services can be scaled to meet changing demands, ensuring optimal performance.
Global Reach: Cloud providers have data centers worldwide, enabling organizations to serve customers in different regions efficiently.

Example

Spotify relies on Google Cloud to manage its growing user base, ensuring seamless music streaming across the globe.

Enhanced Collaboration

Real-Time Access: Employees can access files and applications from anywhere, promoting remote work and collaboration.
Centralized Data: Cloud storage ensures that all team members work with the latest version of documents.

Example

Google Workspace allows teams to collaborate on documents, spreadsheets, and presentations in real-time, improving productivity.
