Virtualization technology allows multiple virtual hosts to run at the same time on a single hardware platform. One physical server may run dozens or hundreds of virtual servers, allowing all of those virtual hosts to share memory and processing power. In this video, learn about how this strategy may introduce security vulnerabilities into your organization.
- [Teacher] Virtualization is a strategy … commonly used to optimize the use of hardware … in both on premises and cloud data centers. … Virtualization technology allows multiple … virtual hosts to run at the same time … on a single hardware platform. … One physical server may run dozens … or hundreds of virtual servers, … allowing all of those virtual hosts … to share memory and processing power. … From a security perspective, … this means that we have to be extra careful … to ensure that systems are isolated from each other. … Virtualization platforms use a component … called the hypervisor … to restrict each virtual machine … so that it can only access areas of memory … reserved for its use. … The hypervisor also prevents virtual machines … from accessing memory belonging … to other virtual hosts … running on the same hardware platform. … You might think of the hypervisor … as the security guard of the virtualized environment. … This separation of access is especially important … in a shared environment like the cloud, …
