Software Deployment
The deployment of a mechanical device, electrical system, computer program, etc., is its assembly or transformation from a packaged form to an operational working state. Deployment implies moving a product from a temporary or development state to a permanent or desired state.
Release
• A product release is the process of launching a new product for a specific market or user base.
• In software development, a product release is sometimes done with a beta version so that core developers/users can assist with debugging and feedback prior to the release of the actual software.
Update
• An update is a software file that contains fixes for problems found by other users or the software developer.
• Installing an update fixes the code and prevents the problems from happening on your computer.
• Because updates fix problems with a program, they are almost always free and available through the program or the companies website.
Patches
• A patch is a software update comprised code inserted (or patched) into the code of an executable program.
• Typically, a patch is installed into an existing software program.
• Patches are often temporary fixes between full releases of a software package.
• Patches may do any of the following:
– Fix a software bug
– Install new drivers
– Address new security vulnerabilities
– Address software stability issues
– Upgrade the software
How to get updates
Manually (download and install them yourself) – Pro: Full control – Con: Time consuming • Automatically (software automatically contacts the developer, downloads and installs any updates) – Pro: Don’t have to think/worry about updates, always up to date – Con: No control – bad update might crash the system
Agile development
• Agile software development describes an approach to software development under which requirements and solutions evolve through the collaborative effort of selforganizing and cross-functional teams and their customers/end users. • It advocates adaptive planning, evolutionary development, early delivery, and continual improvement, and it encourages rapid and flexible response to change.
