Characteristics of Cloud Computing
Cloud computing exhibits several key characteristics:
- On-demand self-service: Users can independently provision, monitor, and manage computing resources without the need for human administrators.
- Broad network access: Services are accessible over standard networks and diverse devices.
- Rapid elasticity: IT resources can swiftly scale up or down in response to changing demands, ensuring efficient resource allocation.
- Resource pooling: Shared resources like networks, servers, and storage are allocated dynamically across multiple applications and users, optimizing resource utilization.
- Measured service: Usage metrics are tracked for each user and application, facilitating billing transparency and resource optimization.
- Multi-tenancy: Cloud providers can serve multiple users or organizations on shared infrastructure, promoting efficiency and scalability.
- Virtualization: Hardware resources are abstracted and presented as logical resources through virtualization technology, enhancing flexibility and resource utilization.
- Resilient computing: Cloud services are designed with redundancy and fault tolerance to ensure high availability and reliability.
- Flexible pricing models: Providers offer various pricing options such as pay-per-use, subscriptions, and spot pricing to accommodate diverse user needs.
- Security: Robust security measures are implemented to safeguard user data and maintain privacy.
- Automation: Automated processes enable seamless deployment and management of resources, reducing manual intervention.
- Sustainability: Cloud providers prioritize sustainability initiatives like energy-efficient data centers and renewable energy adoption to minimize environmental impact.
