Resources/Readwise/Full Document Contents/Articles/NIST SP 800-145, the NIST Definition of Cloud Computing|Full Document Contents]] ## Document Notes 1. **Summarize**: The NIST Special Publication 800-145 provides a comprehensive definition of cloud computing. It describes cloud computing as a model that allows for on-demand network access to a shared pool of configurable computing resources. The model is characterized by on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. It also outlines three service models (SaaS, PaaS, IaaS) and four deployment models (private, community, public, hybrid). The document is a product of the Information Technology Laboratory (ITL) at NIST, which aims to advance the development and productive use of information technology. 2. **Bullet Points**: - Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to shared resources. - Essential Characteristics: - On-demand self-service - Broad network access - Resource pooling - Rapid elasticity - Measured service - Service Models: - Software as a Service (SaaS) - Platform as a Service (PaaS) - Infrastructure as a Service (IaaS) - Deployment Models: - Private cloud - Community cloud - Public cloud - Hybrid cloud - The Information Technology Laboratory (ITL) at NIST promotes the U.S. economy and public welfare by providing technical leadership for the nation’s measurement and standards infrastructure. 3. **Paraphrase**: - "Cloud computing is a model that provides easy, anywhere, anytime network access to a common set of adjustable computing resources. These resources can be quickly supplied and released with minimal management effort or interaction with the service provider." - "The ITL at NIST supports the U.S. economy and public welfare by leading the technical aspects of the nation's measurement and standards infrastructure. ITL develops tests, test methods, reference data, proof of concept implementations, and technical analysis to foster the growth and effective use of information technology." 4. **Press Release**: "Unveiling the NIST Definition of Cloud Computing!

([View Highlight](https://read.readwise.io/read/01h4bx9dv6mn32fvkh9bpcjpc6)) - Essential Characteristics: On-demand self-service. A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider. Broad network access. Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations). Resource pooling. The provider’s computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand. There is a sense of location independence in that the customer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter). Examples of resources include storage, processing, memory, and network bandwidth. Rapid elasticity. Capabilities can be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inward commensurate with demand. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be appropriated in any quantity at any time. Measured service. Cloud systems automatically control and optimize resource use by leveraging a metering capability1 at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service. ([View Highlight](https://read.readwise.io/read/01h4bx9xs7jmqvk54za0zxbyn8)) - Service Models: Software as a Service (SaaS). The capability provided to the consumer is to use the provider’s applications running on a cloud infrastructure2. The applications are accessible from various client devices through either a thin client interface, such as a web browser (e.g., web-based email), or a program interface. The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user- specific application configuration settings. Platform as a Service (PaaS). The capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming ([View Highlight](https://read.readwise.io/read/01h4bxadgvch7cfes4hts7gnnm)) - languages, libraries, services, and tools supported by the provider.3 The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, or storage, but has control over the deployed applications and possibly configuration settings for the application-hosting environment. ([View Highlight](https://read.readwise.io/read/01h4bxamq3aqtjfjj8s72587xa)) - Infrastructure as a Service (IaaS). The capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, and deployed applications; and possibly limited control of select networking components (e.g., host firewalls). ([View Highlight](https://read.readwise.io/read/01h4bxare8tqbdmnr8w0yws7cs)) - Deployment Models: Private cloud. The cloud infrastructure is provisioned for exclusive use by a single organization comprising multiple consumers (e.g., business units). It may be owned, managed, and operated by the organization, a third party, or some combination of them, and it may exist on or off premises. Community cloud. The cloud infrastructure is provisioned for exclusive use by a specific community of consumers from organizations that have shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be owned, managed, and operated by one or more of the organizations in the community, a third party, or some combination of them, and it may exist on or off premises. Public cloud. The cloud infrastructure is provisioned for open use by the general public. It may be owned, managed, and operated by a business, academic, or government organization, or some combination of them. It exists on the premises of the cloud provider. Hybrid cloud. The cloud infrastructure is a composition of two or more distinct cloud infrastructures (private, community, or public) that remain unique entities, but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds).
