Definition of Cloud Computing:

Cloud computing refers to the delivery of computing services—including servers, storage, databases, networking, software, analytics, and more—over the internet (“the cloud”). Instead of owning physical hardware or infrastructure, users access these resources on-demand from cloud service providers.

Key Characteristics of Cloud Computing:

1. On-Demand Self-Service: Users can provision and manage computing resources, such as servers and storage, without human intervention from the service provider.
2. Broad Network Access: Cloud services are accessible over the internet from various devices, including laptops, smartphones, and tablets.
3. Resource Pooling: Computing resources are pooled together and dynamically allocated to multiple users based on demand. Users typically have no control or visibility over the exact location of the resources.
4. Rapid Elasticity: Cloud resources can be rapidly scaled up or down to accommodate fluctuations in demand. This elasticity enables businesses to handle spikes in workload efficiently.
5. Measured Service: Cloud usage is monitored, controlled, and billed based on usage metrics. Users only pay for the resources they consume, similar to utility billing models.

Types of Cloud Services:

1. Infrastructure as a Service (IaaS): Provides virtualized computing resources, such as virtual machines and storage, over the internet. Users have control over the operating systems, applications, and development frameworks.
2. Platform as a Service (PaaS): Offers a platform for developing, testing, and deploying applications without the complexity of managing the underlying infrastructure. PaaS providers manage the infrastructure, runtime, middleware, and development tools.
3. Software as a Service (SaaS): Delivers software applications over the internet on a subscription basis. Users access the applications through a web browser without needing to install or maintain software locally.

Benefits of Cloud Computing:

1.Cost Savings: Eliminates the need for upfront capital investment in hardware and infrastructure.
2.Scalability: Allows businesses to scale resources up or down based on demand, minimizing wastage and maximizing efficiency.
3.Flexibility and Agility: Enables rapid deployment of applications and services, accelerating time-to-market.
4.Accessibility: Provides anytime, anywhere access to computing resources, promoting remote work and collaboration.
