Cloud Computing Basics for JKSSB Computer Awareness - JKSSB Mock Test

Cloud computing is one of the most important topics in the JKSSB Computer Awareness syllabus. This concept is widely used in government offices, IT industries, online storage services, and more. In this article, we’ll cover Cloud Computing basics, features, models, and benefits in simple language, helping you score better in your JKSSB exams.

What is Cloud Computing?

Cloud Computing refers to the delivery of computing services such as servers, storage, databases, networking, software, and more—over the internet ("the cloud"). Instead of using local computers, users access services hosted on remote servers via the internet.

It allows individuals and businesses to use software and hardware managed by third parties at remote locations. Popular examples include Google Drive, Amazon Web Services (AWS), Microsoft Azure, and Dropbox.

Why is Cloud Computing Important for JKSSB Exams?

• Frequently asked topic in JKSSB, SSC, and banking exams.
• Simple concept with high-scoring potential.
• Applicable in real-world government and IT office scenarios.

Key Characteristics of Cloud Computing

• On-Demand Self-Service: Users can access resources whenever they need them.
• Broad Network Access: Services are available over the internet.
• Resource Pooling: Resources are pooled together to serve multiple users.
• Rapid Elasticity: Users can scale resources up or down as needed.
• Measured Service: Users pay only for what they use (Pay-as-you-go model).

Types of Cloud Deployment Models

Cloud computing is classified based on how it is deployed and accessed:

1. Public Cloud

Managed by third-party providers. Services are delivered over the internet and available to anyone. Example: Google Drive, Dropbox.

2. Private Cloud

Used by a single organization. Provides more control and security. Example: Private servers of banks and government offices.

3. Hybrid Cloud

Combination of both public and private cloud. It offers flexibility and more deployment options.

Cloud Service Models

Cloud services are categorized into three primary models:

1. IaaS (Infrastructure as a Service)

Provides virtualized physical computing resources over the internet. Example: Amazon EC2, Microsoft Azure.

2. PaaS (Platform as a Service)

Offers hardware and software tools (like OS, database, server) over the internet. Example: Google App Engine.

3. SaaS (Software as a Service)

Delivers software applications over the internet on a subscription basis. Example: Gmail, Microsoft Office 365.

Examples of Cloud Computing

• Google Docs: Create and edit documents online.
• Netflix: Streaming services hosted on AWS cloud.
• Google Photos: Online photo backup and storage.
• Dropbox: File storage and sharing platform.

Benefits of Cloud Computing

• Cost Effective: No need for expensive hardware/software.
• Scalable: Easily scalable as per the requirement.
• Flexible: Work from anywhere with internet access.
• Secure: Data is stored in encrypted form with backup options.
• Automatic Updates: Software is updated automatically by the provider.

Disadvantages of Cloud Computing

• Internet Dependency: Requires stable internet connection.
• Limited Control: Users rely on cloud providers for maintenance.
• Security Risks: Data privacy and hacking concerns.

Cloud Computing in Government Sector

The Indian government is promoting cloud computing through its initiative called MeghRaj, launched by the Ministry of Electronics and Information Technology (MeitY). Its goal is to use cloud services to improve efficiency, reduce costs, and promote e-Governance.
