Abstract: Techniques for secure and efficient interfacing with a cloud computing service are described. In an embodiment, a cloud computing management service is programmed or configured to communicate with a cloud computing service. The cloud computing management service can be accessed by software engineers that are looking to deploy a software instance to a computing device of the cloud computing service. Thus, the cloud computing management service acts as an intermediary layer in front of the cloud computing service. In an embodiment, the cloud computing management service may store one or more frequently-used system parameters for deployment of software instances. The parameters conform to company's security protocols, compliance protocols, and/or other standards.

Abstract: A paintball gun for propelling paintballs has a barrel formed with a loading tube and a hopper for feeding paintballs into the loading tube for delivery to the barrel. A cleaning ball storage and feeding device is interconnected between the hopper and the loading tube for selectively feeding cleaning balls into the barrel to purge the barrel from shell particles and filler paint deposited from a previously propelled ruptured paintball.
