4.2.1.1. Application Developer Use Case
Application developers are skilled in IT and require many vApp configurations with different internal virtual machine configurations and software package installation configurations. Rather than trying to predict the requirements for each developer, the infrastructure team can provide a collection of media files and basic, predefined standard vApp templates based on an existing corporate standard. Developers can then construct their own individual vApps and modify the configuration (CPU, RAM, disk) of the contained virtual machines. You might not need to create many vApp templates in advance because a single vApp template for each major guest operating system and application might be enough. There is no requirement to define small, medium, and large hardware-based derivatives of the same vApp template, because the user can edit the virtual hardware after deployment.
