Software deployment is the process of making software usable on one or more systems. Both single and multi-system deployment involve four primary steps:
The installation process is the primary deployment step, in which the application and corresponding files are installed on one or more systems. Installation options include where to install the software and what files to install, such as add-ons and other extras.
Commercial software programs often require activation, either immediately or after a trial period. Without activation, the software may run for a limited time or with limited features. The activation process requires purchasing a license and entering the activation key.
The final step of deployment is updating the software to the latest version. Many applications include a "Check for updates" command to check if a newer version is available. Keeping software up-to-date reduces issues with bugs, security holes, and incompatibilities.
Deploying software on a home PC is often as simple as downloading, installing, and activating the program. Deployment on corporate machines or across multiple systems on a network can be more complex. For example, a network administrator may need to configure a program identically on dozens of computers. To ensure consistency, the admin may use a command-line interface or a deployment script to automate the installation process.
