What is cloud computing?

Cloud computing is a technology that allows users to access and store data, applications, and services over the Internet instead of relying on local servers or personal computers. This model provides on-demand availability of computing resources, enabling users to utilize services such as storage, processing power, and software applications without the need for physical infrastructure.
Key Features of Cloud Computing

1. Accessibility: Users can access cloud services from anywhere and at any time, provided they have an Internet connection. This flexibility supports remote work and collaboration.
2. Cost Efficiency: Cloud computing operates on a pay-as-you-go model, allowing businesses to avoid the upfront costs of purchasing hardware and software. Instead, they pay for the resources they use, which can lead to significant cost savings.
3. Scalability: Cloud services can be easily scaled up or down based on demand. This means businesses can adjust their resource usage according to their needs without over-provisioning.
4. Variety of Services: Cloud computing encompasses several service models, including:
   • Infrastructure as a Service (IaaS): Provides virtualized computing resources over the Internet.
   • Platform as a Service (PaaS): Offers hardware and software tools over the Internet, typically for application development.
   • Software as a Service (SaaS): Delivers software applications over the Internet on a subscription basis.
5. Data Backup and Recovery: Cloud computing solutions often include automated backup and disaster recovery options, ensuring data is secure and can be restored in case of loss.

Benefits of Cloud Computing

• Agility: Organizations can quickly deploy and manage applications, facilitating faster innovation and development cycles.
• Elasticity: Businesses can adjust their resource allocation dynamically, responding to fluctuating workloads without manual intervention.
• Security: Many cloud providers offer robust security measures, including encryption and compliance with regulatory standards, to protect sensitive data.
