Cloud
Cloud computing is a paradigm that enables access to a shared pool of computing resources over the internet, on-demand, and with pay-as-you-go pricing. Instead of owning and maintaining physical servers and data centers, users can access computing resources like servers, storage, databases, networking, software, and more from cloud service providers.
Key concepts and benefits of cloud computing:
- On-Demand Self-Service
- Scalability and Elasticity
- Resource Pooling
- Broad Network Access
On-Demand Self-Service
Users can provision computing resources, such as virtual machines or storage, as needed without requiring human intervention from the service provider.
Scalability and Elasticity
Cloud resources can be scaled up or down dynamically to meet changing demands. This scalability allows businesses to handle varying workloads efficiently, ensuring optimal performance and cost-effectiveness.
Resource Pooling
Cloud providers pool computing resources to serve multiple customers, allowing for more efficient resource utilization and cost-sharing, leading to lower costs for users.
Broad Network Access
Cloud services are accessible over the internet from various devices, such as laptops, smartphones, and tablets, enabling users to access resources from anywhere with an internet connection.
Service Models
Cloud computing offers different service models:
Infrastructure as a Service (IaaS)
Provides virtualized computing resources over the internet, such as virtual machines, storage, and networking.
Platform as a Service (PaaS)
Offers a platform for developing, running, and managing applications without worrying about the underlying infrastructure.
Software as a Service (SaaS)
Delivers software applications over the internet on a subscription basis, eliminating the need for users to install, maintain, and update software locally.
Deployment Models
Cloud computing can be deployed in various ways:
Private Cloud
Resources are dedicated to a single organization and hosted either on-premises or by a third-party provider.
Hybrid Cloud
It combines public and private clouds, allowing data and applications to be shared between them.
Multi-Cloud
Multi-cloud involves using services from multiple cloud providers to meet specific business requirements.
