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.
SOA is all about architecture-after all, it's right there in the acronym-yet most organizations think it is about turning existing software components into web services. When you adopt SOA, remember that it is all about design and governing that design. It's about how you design your service interfaces, your services, your data model, and your business processes. It's about how you keep track of your services, how you control the design, definition, deployment, and distribution of your services and their artifacts, how you define a service contract and service level agreement for your service consumers, how to secure your services, and how to react when things go wrong with them.

Cloud computing requires DevOps-the blending of development and operations with the goal of accelerating time-to-market and reducing time-to-value. The good news is that ITIL® is uniquely positioned to accelerate DevOps, but it requires changes to existing ITSM processes.
