What is Cloud Computing?
Cloud computing refers to the delivery of computing services—including storage, processing, databases, and software—over the internet instead of relying on local servers or personal computers. These services are hosted on remote data centers and provided by cloud service providers like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).
Key Features of Cloud Computing:
On-Demand Self-Service: Users can access resources without human intervention.
Scalability: Resources can be adjusted based on demand.
Pay-as-You-Go Pricing: Businesses only pay for the resources they use.
Security & Compliance: Cloud providers ensure data security with encryption, firewalls, and compliance measures.
Types of Cloud Computing
Cloud computing is categorized into three primary deployment models and three service models.
1. Cloud Deployment Models
| Deployment Model | Description | Use Cases |
|---|---|---|
| Public Cloud | Cloud resources shared among multiple users and hosted by third-party providers. | Web applications, software testing, e-commerce. |
| Private Cloud | Cloud infrastructure used exclusively by one organization. | Banking, government agencies, healthcare. |
| Hybrid Cloud | A mix of public and private clouds for optimized performance and security. | Large enterprises, data-sensitive industries. |
2. Cloud Service Models
| Service Model | Description | Examples |
| Infrastructure as a Service (IaaS) | Provides virtualized computing resources over the internet. | AWS EC2, Google Compute Engine |
| Platform as a Service (PaaS) | Delivers a platform for developers to build and deploy applications. | Google App Engine, Azure App Services |
| Software as a Service (SaaS) | Fully managed software applications accessed over the internet. | Google Drive, Microsoft 365, Dropbox |
