Implementing virtualization in the data center represents the first step toward leveraging cloud-based computing and reducing costs. For example, in the case of Colosseum Online, the company needed to increase capacity to meet intense provisioning requirements, an expanding customer base, and ongoing management needs. Instead of operating as a conventional ISP with a standard server-based data center, the company wanted to offer co-location, scalable cloud capabilities, and network services.

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.

The nature of IT is to stay ahead of the curve in all things related to technology. Today, the expectation is that IT professionals will have a measure of capability, if not proficiency, in everything from wireless networking and security to mobile app development and maintaining a cloud-based infrastructure. However, IT pros can’t be everywhere at once. By developing skillsets in certain areas, both entry-level and accomplished IT veterans can remain current with changing trends and adapt to new ones.
