Other important services could be provided by the AH to applications during their execution.
The

other various services while the application is running, such as remote debugging. The AH
Execution Phase is depicted in Figure 2.4.

The AH Execution Phase in detail.
The overall picture is quite complete. After zooming into the major phases, we will illustrate
the detailed model with some well-known cases.

The Complete Model
The AH Check-Out Phase is generally made up of two main stages: After a preliminary com-
munication between the AH and the Deployment Server (whenever possible) and an eventual
user authentication, the Resolution Phase will take place.
The AH-DS Connection Phase represents the optional connection establishment between the
AH and the Deployment Server prior to the Resolution Phase.
The Resolution Phase consists of checking the outcome of decisions regarding the whole
deployment lifecycle.
