Description: Environment as a Service (EaaS) is a cloud service model that provides a complete environment for application development and testing. This approach allows developers to access a set of tools, platforms, and resources necessary to create, test, and deploy software without the need to manage the underlying infrastructure. EaaS is based on virtualization and automation, facilitating the creation of scalable and replicable development and testing environments. Its main features include flexibility, as users can configure specific environments according to their needs; efficiency, by reducing the time and costs associated with setting up hardware and software; and collaboration, allowing distributed teams to work in the same environment without compatibility issues. This model is particularly relevant in a world where agility and speed in software development are crucial for business success. EaaS often integrates with other cloud services, such as Infrastructure as a Service (IaaS) and Platform as a Service (PaaS), creating a robust ecosystem that supports the entire software development lifecycle comprehensively.
