Automatic elasticity in OpenStack
Leander Beernaert, Miguel Matos, Ricardo Manuel Pereira Vilaca, Rui Oliveira · 2012
Cloud computing infrastructures are the most recent approach to the development and conception of computational systems. Cloud infrastructures are complex environments with various subsystems, each one with their own challenges. Cloud systems should be able to provide the following fundamental property: elasticity. Elasticity is the ability to automatically add and remove instances according to the needs of the system. This is a requirement for pay-per-use billing models.
