What are the three main components involved in IAC for a mash-up?

The chosen answer highlights the three main components of Integrated Application Controls (IAC) for a mash-up, emphasizing the significance of each element in the context of Pega's framework.

The Pega Gadget Manager acts as a central repository that manages the gadgets, which are reusable user interface components that provide functionality within Pega applications. These gadgets enable seamless integration between different web applications, facilitating the display and interaction of UI elements from various sources.

The Pega Instance embodies specific instances of data and processes that exist within the application. This ensures that the application can operate dynamically, accommodating various user interactions and states as they engage with the mash-up.

The Pega Composite Gateway serves as the communication bridge between Pega applications and external systems or components. It facilitates the exchange of data and events in real-time, allowing the mash-up to pull in information and functionalities from different sources effectively.

Understanding these components' roles is crucial for designing effective mash-ups in Pega, as they ensure that the applications are well-integrated, efficient, and provide a cohesive user experience.

While the other choices mention various components or tools within the Pega ecosystem, they do not specifically encapsulate the key elements related to the concept of IAC in the context of mash-ups as accurately
