Abstract: A method and system for optimizing placement of a plurality of software components of cloud services in a cloud computing network, generates a service deployment model with a placement optimization description described as constrained optimization problem, by matching service constraints to infrastructure capacity in combination with optimization criterium, thus enable the method and system to deploy new services and/or redeploy existing services in a profitable, efficient and flexible way.

Abstract: A device to be used with an adjusting element comprising a rod piston (3) displaceable with the aid of a motor (4) in a piston tube (2). The motor (4) is rotatably arranged at the adjusting element (1) through a worm gear (6), either directly or through a motor attachment (5), wherein the motor (4) extends in an extension plane in parallel with the piston tube (2), said worm gear (6) having a throat formation (7) for axial fixation of the position of the motor (4) in the adjusting element (1) while a free rotation of the motor (4) is practicable through 360° in order to make possible, in applications with limited space, an eligble position fixation of the motor (4) in a predetermined angle in relation to the adjusting element (1).
