Nowadays, due to the extremely fast advance of the requirements, features, and expectations from the users, and as a result, the incredible, but the somewhere understandable effort of the big players in this market to surpass the competition through a continuous reinvention and attempt to meet market expectations, we are witnessing a continuous, even exponential evolution of technology. Virtualization is a complex and vast technology, one of its most key factors to consider is the resources. Because there is a clear interdependence between the volume of resources and costs, it is easy to deduce that a large number of resources involves higher costs. Modern technologies, like containerization, are coming to resolve this bottleneck, by providing more optimized and more transferable ecosystems. And a short comparison can be seen in this research paper, between virtualization and containerization.
