Utilizando virtualização baseada em containers para criação de laboratórios práticos de disciplinas na área de TI

Abstract

The development of laboratory practice in courses of Information Technology (IT) is an important way to offer students a means of gaining experience. But the problem behind these practices is that educational institutions generally do not have enough money to provide a dedicated structure for these laboratories. Thus, virtualization becomes a way to solve this problem by enabling the execution of guests on a host systems, thereby reducing the physical infrastructure. In-based virtualization hypervisors, a complete operating system runs on a host, which becomes a problem, because in this type of virtualization there is excessive consumption of the host resources. To solve this, containers based virtualization has emerged, on which, unlike the hypervisors, store only the necessary libraries to run an application, sharing the kernel with the host, which makes this type of virtualization lighter and efficient. Knowing this, this paper aims to present a tool that automates the creation of virtualised study environments for students in the area of IT using containers, which enables the creation, execution or management of a scenario for practical activity quickly and easily. The results obtained from the quantitative evaluation carried out show that the developed tool pleased the teachers interviewed and was considered a useful tool for the development of laboratory activities.
