<table><tr><td> </td></tr></table><p><strong>Definition</strong> </p><table><tr><td> </td></tr></table><p>A model for enabling on-demand network access to a shared pool of configurable IT capabilities/ resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. It allows users to access technology-based services from the network cloud without knowledge of, expertise with, or control over the technology infrastructure that supports them. This cloud model is composed of five essential characteristics (on-demand self service, ubiquitous network access, location independent resource pooling, rapid elasticity, and measured service); three service delivery models (Cloud Software as a Service [SaaS], Cloud Platform as a Service [PaaS], and Cloud Infrastructure as a Service [IaaS]); and four models for enterprise access (Private cloud, Community cloud, Public cloud, and Hybrid cloud). Note: Both the user&#39;s data and essential security services may reside in and be managed within the network cloud. </p><table><tr><td> </td></tr></table><p><strong>Source</strong><strong></strong> </p><p><strong></strong> </p><table><tr><td> </td></tr></table><p><a href="https://nvlpubs.nist.gov/nistpubs/Legacy/SP/nistspecialpublication800-145.pdf">NIST SP 800-145, The NIST Definition of Cloud Computing</a>; NOAA Cloud Computing Lexicon and Related Terms </p><p>NESDIS Data Management Lexicon and Related Terms </p><p><strong>Category</strong> </p><p><a href="https://eur03.safelinks.protection.outlook.com/?url=http%3A%2F%2Fcalvalportal.ceos.org%2Ft-d_wiki%3Fp_p_id%3D54_INSTANCE_Wg3ti1194i20%26p_p_lifecycle%3D0%26p_p_state%3Dnormal%26p_p_mode%3Dview%26p_p_col_id%3Dcolumn-2%26p_p_col_count%3D1%26_54_INSTANCE_Wg3ti1194i20_struts_action%3D%252Fwiki_display%252Fview%26_54_INSTANCE_Wg3ti1194i20_nodeName%3DCEOS_Terms_and_Definitions%26_54_INSTANCE_Wg3ti1194i20_title%3D4.%2BData%2BStewardship%2Bwords&amp;data=04%7C01%7Cfaye.lai%40npl.co.uk%7C7e8026d1a5234b925ae608d9ab43fb32%7C601e5460b1bf49c0bd2de76ffc186a8d%7C1%7C0%7C637729130733353002%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&amp;sdata=BSCt%2BTOPgNdhHFMcRZaFFLWTqAXlV%2B3wqf1pCLydTu4%3D&amp;reserved=0">4.
