For organizations, the cloud’s per-use approach provides tangible relief from hardware or software investments by offering a pay-for-service model. The benefits include greater resource access, dynamic scaling, and improved costs, along with the ease of automated management for resources and performance. Companies adopt cloud computing to reduce infrastructure overhead, adjust service levels to meet changing needs, and to quickly deliver applications. However, with these advantages come certain limitations, especially in relation to security.

Organizations of all sizes have identified the benefits of cloud-based computing, whether it’s implementing a private or hybrid cloud on their own or accessing a public cloud through a service provider. Virtualization, a key component for building secure cloud environments, offers many advantages, including higher machine efficiency due to increased utilization, energy savings, and the flexibility to build or destroy virtual machines (VMs) on demand to meet changing organizational needs.

Choosing open source virtualization over proprietary alternatives can significantly increase savings. However, an open source Linux Kernel-based virtual machine (KVM) offers several benefits to organizations beyond just cost savings. These benefits include security, reliability, availability, performance, and scalability. In this white paper, we’ll look at the relationship between open source virtualization and the cloud, and explore the security aspects of KVM hypervisor technology, especially in relation to how it leverages SELinux and related capabilities for secure public, private, and hybrid cloud performance.
