AWS CloudFormation is a service provided by Amazon Web Services (AWS) that enables users to model and manage infrastructure resources in an automated and secure manner. [1] Using CloudFormation, developers can define and provision AWS infrastructure resources using a JSON - or YAML -formatted infrastructure as code template.
Terraform was previously free software available under version 2.0 of the Mozilla Public License (MPL). On August 10, 2023, HashiCorp announced that all products produced by the company would be relicensed under the Business Source License (BUSL), with HashiCorp prohibiting commercial use of the community edition by those who offer "competitive services".
IaC grew as a response to the difficulty posed by utility computing and second-generation web frameworks. In 2006, the launch of Amazon Web Services’ Elastic Compute Cloud and the 1.0 version of Ruby on Rails just months before [2] created widespread scaling difficulties in the enterprise that were previously experienced only at large, multi-national companies.

Example of a web form with name-value pairs. A name–value pair, also called an attribute–value pair, key–value pair, or field–value pair, is a fundamental data representation in computing systems and applications. Designers often desire an open-ended data structure that allows for future extension without modifying existing code or data.
A key management system (KMS), also known as a cryptographic key management system (CKMS) or enterprise key management system (EKMS), is an integrated approach for generating, distributing and managing cryptographic keys for devices and applications. They may cover all aspects of security - from the secure generation of keys over the secure ...
The pre-shared key may be shared between the two parties, or each party may share a key with a trusted third party. If there is no secure channel (as may be established via a pre-shared key), it is impossible to create an authenticated session key. [10] The session key may be generated via: key transport, key agreement and hybrid.
Public-key cryptography, or asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys. Each key pair consists of a public key and a corresponding private key. [1] [2] Key pairs are generated with cryptographic algorithms based on mathematical problems termed one-way functions.
NASA's Nebula platform. In July 2010, Rackspace Hosting and NASA announced an open-source cloud-software initiative known as OpenStack. [7] [8] The mission statement was "to produce the ubiquitous Open Source Cloud Computing platform that will meet the needs of public and private clouds regardless of size, by being simple to implement and massively scalable".
