- Infrastructure as a Service (IaaS)
Provides virtualized computing resources via the internet. You manage the OS, applications, storage; the vendor manages the infrastructure.
Examples: AWS EC2, Microsoft Azure VM, Google Compute Engine
- Platform as a Service (PaaS)
Delivers tools and services to develop, test, and deploy applications without managing infrastructure.
Examples: Google App Engine, Heroku, Microsoft Azure App Services
- Software as a Service (SaaS)
Delivers software applications via the cloud, managed entirely by the service provider.
Examples: Google Workspace, Dropbox, Zoom, Salesforce
Deployment Models in Cloud Computing
- Public Cloud
Services are delivered over the public internet and shared across multiple organizations.
Example: Amazon Web Services (AWS), Google Cloud Platform (GCP)
- Private Cloud
Dedicated cloud infrastructure for a single organization, offering enhanced control and security.
Example: OpenStack, VMware Private Cloud
- Hybrid Cloud
Combines both public and private clouds, allowing data and apps to be shared between them.
- Community Cloud
Shared infrastructure among multiple organizations with similar needs and policies.
