5 NIST Essential Cloud Characteristics
The National Institute of Standards and Technology (NIST) provides a definitive description of cloud computing. NIST states that a technology model must possess all five of the following characteristics to be considered a cloud:
On-demand self-service: Anyone with a browser can subscribe to cloud services. This is a technology first.
Measured service: Monitoring and reporting capabilities enable cloud providers to offer services by subscription, pay-per-use and other pricing models that are based on usage.
Elastic scalability: Cloud subscribers can increase or decrease computing resources rapidly.
Resource pooling: Virtualized servers, storage, and networks are pooled together within a single location or from many locations across multiple geographies to create a seemingly infinite supply of cloud computing resources.
Broad network access: Cloud technology requires broad network access to support efficient service acquisition and delivery. Today, the internet provides a standard protocol for connectivity to public clouds with additional options, such as MPLS (Multiprotocol Label Switching), available for private clouds for improved performance and security.
No more waiting: In the past, you had to ask an IT administrator to fulfill your computing needs — then your request would enter the administrator’s queue. With cloud computing, there’s no wait time. You just need a browser to acquire the resources you need. You can provision a platform stack with just a few clicks. Cloud APIs and an orchestration engine do the rest.
