What is Cloud Computing ?
Cloud Computing is a technology model that delivers computing resources like servers, storage, databases, networking, security, analytics and software. Instead of owning physical hardware or running complex data centers, organizations access these resources through cloud service providers like Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP) and others.

In simple words
Cloud Computing is a method technology that allows users to store data, access software and run applications or remote servers through the internet instead of using a computer’s local storage.
Major tasks of Cloud computing
- In cloud computing, all major computing tasks are handled in remote data centers located worldwide.
- These data centers are highly secure, scalable, and optimized for massive workloads.
- Users can access applications and services anytime, from anywhere, through the internet.
- This gives businesses flexibility, reduces cost, improves performance, and supports global access.

Cloud computing operations
- It operates through virtualization technology, which creates virtual machines and environments.
- And allows multiple users to share the same infrastructure securely.
- It also supports automation, auto-scaling, load balancing, and disaster recovery, making business operations more reliable and efficient.
Key Features of Cloud Computing
- On-Demand Service:- Resources are available whenever required.
- Scalability:- Increase or decrease resources based on business needs.
- Flexibility:– Access applications from any device, anywhere.
- Cost-Effective:- No need to buy physical hardware.
- High Security:- Data is protected with advanced encryption and monitoring.
- Automatic Updates:- Cloud providers handle all security and software updates.
- Disaster Recovery:– Backup and restore systems easily.
Types of Cloud Computing
- IaaS (Infrastructure as a Service):- Provides virtual servers, storage, and networking.
- PaaS (Platform as a Service):- Provides platforms for developers to build, test, and deploy applications.
- SaaS (Software as a Service):- Applications hosted on the cloud and accessed via the internet
- Public Cloud: Resources (servers, storage) shared among many users, owned by a provider (AWS, Azure, GCP), offering scalability and cost-effectiveness.
- Private Cloud: Dedicated infrastructure for one organization, offering maximum control and security (like your own data center in the cloud).
- Hybrid Cloud: Combines public and private clouds, allowing data/apps to move between them for flexibility.
- Multi-Cloud: Uses multiple public clouds from different providers for redundancy or specific services.
