Software deployment is all of the activities that make a software system available for use. The general deployment process consists of several interrelated activities with possible transitions between them. These activities can occur at the producer side or at the consumer side or both.
Because every software system is unique, the precise processes or procedures within each activity can hardly be defined. Therefore, "deployment" should be interpreted as a general process that has to be customized according to specific requirements or characteristics.
Deployment is defined as the movement of staff from ones' current assignment to another to meet operational needs. ...

Software Deployment Meaning: Software deployment includes all of the steps, processes, and activities that are required to make a software system or update available to its intended users. Today, most IT organizations and software developers deploy software updates, patches and new applications with a combination of manual and automated processes. Some of the most common activities of software deployment include software release, installation, testing, deployment, and performance monitoring.
Deployment in software and web development means to push changes or updates from one deployment environment to another. When setting up a website you will always have your live website, which is called the live environment or production environment.
If you want the ability to make changes without these affecting your live website, then you can add additional environments. These environments are called development environments or deployment environments. The additional development environments will typically be a local environment, a development environment and a staging environment (also known as a staging site). How many environments you need is up to you and depends on the complexity of the project you are working on.
While deployment models can vary, the most common is the classic “left to right” deployment model when working with multiple deployment environments. In this model changes are made in local, development or staging environments (depending on the setup) and pushed from left to right through the different environments ending up in the live environment. Once this deployment process has completed the new changes will be visible in the live environment.
