Cloud Foundry is an open source, multi-cloud application platform as a service (PaaS) governed by the Cloud Foundry Foundation, a 501(c)(6) organization. [1]The software was originally developed by VMware, transferred to Pivotal Software (a joint venture by EMC, VMware and General Electric), who then transferred the software to the Cloud Foundry Foundation upon its inception in 2015.
Function as a service is a "platform-level cloud capability" that enables its users "to build and manage microservices applications with low initial investment for scalability," according to ISO/IEC 22123-2. [1] Function as a Service is a subset of the serverless computing ecosystem. [2]
The name came from the Pivotal Labs LLC which had been acquired by EMC, and briefly used the name GoPivotal, Incorporated. [3] On April 24, 2013, the organization announced a US$105 million investment from General Electric (for 10% equity) and Pivotal One, including Cloud Foundry for cloud computing. [4] [5]
BOSH is not commercially distributed as a standalone product. It is included as part of Pivotal Cloud Foundry, IBM Bluemix, and HP Helion Developer Platform, and is also used and supported commercially by Cloud Credo, Stark & Wayne, Gstack, and others.
Dirichlet lambda function, λ(s) = (1 – 2 −s)ζ(s) where ζ is the Riemann zeta function; Liouville function, λ(n) = (–1) Ω(n) Von Mangoldt function, Λ(n) = log p if n is a positive power of the prime p; Modular lambda function, λ(τ), a highly symmetric holomorphic function on the complex upper half-plane
In the untyped lambda calculus, where the basic types are functions, lifting may change the result of beta reduction of a lambda expression. The resulting functions will have the same meaning, in a mathematical sense, but are not regarded as the same function in the untyped lambda calculus. See also intensional versus extensional equality.
In computer programming, an anonymous function (function literal, expression or block) is a function definition that is not bound to an identifier. Anonymous functions are often arguments being passed to higher-order functions or used for constructing the result of a higher-order function that needs to return a function. [ 1 ]
A function's identity is based on its implementation. A lambda calculus function (or term) is an implementation of a mathematical function. In the lambda calculus there are a number of combinators (implementations) that satisfy the mathematical definition of a fixed-point combinator.
