Cloud computing allows users to access computing resources (servers, storage, databases, software, etc.) over the internet. By eliminating the need for physical hardware, users can access these services through an internet connection, which distinguishes cloud computing from traditional systems.
Types of Cloud Computing
Service Models:
- Infrastructure as a Service (IaaS): Provides fundamental computing resources like servers, networks, and storage. Examples: Amazon Web Services (AWS), Google Cloud.
- Platform as a Service (PaaS): Offers platforms for application development and deployment. Examples: Microsoft Azure, Heroku.
- Software as a Service (SaaS): Enables users to access software over the internet. Examples: Google Workspace, Dropbox.
Deployment Models:
- Public Cloud: Offers services accessible to everyone and provides a cost-effective solution.
- Private Cloud: Provides a secure environment customized for a single organization.
- Hybrid Cloud: Combines public and private cloud solutions.
Advantages of Cloud Computing
- Flexibility: Resources can be scaled up or down as needed.
- Cost Savings: Eliminates hardware and maintenance expenses.
- Accessibility: Data and applications can be accessed from anywhere.
- Security: Provides data backup and disaster recovery systems.
