Essential Characteristics of Cloud Computing
Cloud computing is the delivery of computing services such as servers, storage, databases, networking, software, analytics, and intelligence over the internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale. The National Institute of Standards and Technology (NIST) defines cloud computing by five essential characteristics that any cloud service must possess. Here are the top five essential characteristics of cloud computing.
- On-demand self-service: The ability to provision, use, and deprovision resources or services automatically, immediately, and without manual intervention from a service provider.
- Broad network access: The ability to access cloud services or any resource over the internet or any network using standard mechanisms and devices such as mobile phones, tablets, laptops, and workstations.
- Resource pooling: The ability to provide shared computing resources among a pool of users to serve multiple customers using a multi-tenant model with different physical and virtual resources, dynamically assigned and reassigned according to customer demand.
- Rapid elasticity: The ability to automatically and quickly expand or shrink computing resources to meet changing demand from customers or as dictated by the workload.
- Measured service: The ability to monitor and measure the usage and performance of the cloud service continuously, transparently, and in a granular way to enable billing, capacity planning, and service optimization.
On-Demand Self-Service
Cloud computing allows end-users to access cloud resources such as servers, storage, and applications without the need for any manual intervention from the service provider. On-demand self-service is an automated process that enables customers to provision or deprovision computing resources using a self-service portal, web browser, or API on the fly. Customers can monitor and manage their own cloud usage, enabling them to scale their services without relying on IT teams or external vendors.
Broad Network Access
The cloud services are available over the internet and can be accessed globally from any device with an internet connection. Broad network access gives customers the flexibility to work from anywhere, on any device and access their applications, data and services securely from the cloud. With cloud-based services, customers can collaborate with their team from different locations and access the same set of information simultaneously.
Resource Pooling
Resource pooling is the process of sharing a common pool of computing resources among multiple customers with different requirements. The cloud resources such as CPU, storage, memory and network bandwidth, are virtual and logically partitioned among the customers, but physically located in a shared pool. This shared model allows customers to achieve economies of scale by utilizing a common infrastructure to run their apps and services.
Rapid Elasticity
| Cloud Computing | Traditional Computing |
|---|---|
| Cloud computing resources can be scaled up or down automatically and on the fly, based on the customer demand | Traditional IT hardware has fixed capacity and can’t expand or shrink dynamically. |
| Cloud computing resources are provisioned and decommissioned easily and quickly, reducing the time-to-market of new applications and services. | Traditional IT hardware is expensive to scale, maintain, and upgrade, increasing the overall cost. |
Rapid elasticity is the ability of cloud computing to scale computing resources up or down easily and instantaneously, depending on the workload. The cloud provider can automatically allocate more CPU, memory, or bandwidth when there is a spike in demand or reduce the resources when demand decreases. This elastic model allows customers to pay only for the resources and services they use and avoid the wasted capacity and overspending of traditional computing.
Measured Service
Cloud computing services can measure and monitor the usage of compute, storage, and network resources in real-time. The cloud provider can provide usage reports regularly to the customers, showing the consumption of the resources. This measured service model gives customers transparency and visibility into their cloud usage, enabling them to optimize their deployment, detect billing errors, and forecast their future capacity needs.
