Without question, today, there is considerable focus on securing the Cloud. This is especially true for virtualization systems, which have played a major role in creating cloud computing. However, the downsides to virtualization involve security challenges.In this scenario, Docker containers play a big part in virtualization as a way for deploying cloud solutions. A Docker is described as an open-source system of software containers, and these containers help software to run while being moved from one environment to another. However, like the many and varied aspects of cloud computing, Docker containers are under scrutiny for their security levels.
