Cloud computing refers to the provision of computational resources such as servers, storage, databases, networking, software, and analytics over the internet. Instead of owning physical hardware, users can access resources via the cloud.
| Features | Details |
|---|---|
| On-Demand Services (मंगी पर सेवा) | Users can access resources as needed without manual intervention. |
| Scalability (स्केलेबिलिटी) | It allows seamless scaling up or down of resources based on requirements. |
| Cost-Effective (लागत में फायदेमंद) | Pay only for the resources you use, reducing unnecessary expenses. |
| Accessibility (प्राप्तिकता) | Access data and applications from anywhere using an internet connection. |
Types of Cloud Computing (क्लाउड कंप्यूटिंग के प्रकार)
- Public Cloud (जनसी क्लाउड): Services are provided over the internet and shared among multiple users.
- Example: Microsoft Azure, Google Cloud.
- Private Cloud (निजी क्लाउड): Exclusively used by a single organization for better security and control.
- Example: VMware, OpenStack.
- Hybrid Cloud (हाइब्रिड क्लाउड): Combines public and private clouds, offering flexibility and cost benefits.
- Example: IBM Hybrid Cloud.
| Type | Advantages | Challenges |
| Public Cloud | Cost-effective, scalable, accessible. | Security concerns, dependency on internet. |
| Private Cloud | Enhanced security, dedicated resources. | Higher cost, limited scalability. |
| Hybrid Cloud | Best of both worlds, flexible operations. | Complex management, potential data integration issues. |
Service Models (सर्विस मॉडल्स)
Cloud computing services are broadly classified into three models:
- Infrastructure as a Service (IaaS): Provides virtualized computing resources over the internet.
- Example: Amazon EC2, Google Compute Engine.
- Platform as a Service (PaaS): Offers a platform for developing, testing, and deploying applications.
- Example: Microsoft Azure App Services, Heroku.
- Software as a Service (SaaS): Delivers software applications over the internet on a subscription basis.
- Example: Google Workspace, Salesforce.
| Service Model | Purpose | Examples |
| IaaS | Provides basic infrastructure like servers, storage, and networking. | AWS EC2, Microsoft Azure Virtual Machines. |
| PaaS | Simplifies app development by providing a platform and tools. | Heroku, Google App Engine. |
| SaaS | Offers ready-to-use applications over the internet. | Dropbox, Slack, Office 365. |
Benefits of Cloud Computing (क्लाउड कंप्यूटिंग के फायदे)
- Cost Savings (खर्च की बचत): Eliminates the need for physical infrastructure, reducing capital expenditure.
- Flexibility and Scalability (प्रफाइन और चूसा जोड़ना): Scale resources up or down depending on business needs.
- Automatic Updates (ऑटोमेटिक अपडेट): Receive updates automatically without manual intervention.
- Disaster Recovery (प्राकृति सुधार): Ensures data safety and quick recovery in case of data loss.
- Environmental Benefits (पर्यावारणीय फायदे): Promotes energy efficiency by reducing the carbon footprint.
