Server virtualization infrastructure and architecture

How you build your virtualization infrastructure and architecture is one of the most major decisions you make, and your choices will dictate whether your virtualized environment helps you consolidate physical servers, space, reduce costs and improve resource utilization or whether it suffers from performance problems, virtual machine security risks, virtual sprawl, virtualization licensing and compliance problems, and other management issues. From the server hardware, operating systems and networking choices to your choice of virtual systems management tools, your virtualized environment has certain requirements to ensure virtual machine performance, system uptime, VM security and compliance and more. Whether you're building a private cloud or developing an environment for a public cloud, you need to know how to design and architect your virtualization environment for these requirements. This section provides news, advice and how-to's on building a virtualized infrastructure, so you make can informed decisions about your virtualization environment make sense for your virtualized architecture and offers best practices on how to build a server virtualization architecture that grows with your business needs and technical requirements.

Server virtualization security management and compliance policies

For virtualization administrators, virtual machine security has become an increasing concern. How do you monitor VMs for potential security risks and breaches? How do you prevent bugs from breaking through the virtual wall and attacking the host system? And which virtual machine guidelines should your IT shop adopt to ensure that your virtual machines are secure? So too, if your large virtualized virtualization environment suffers from a lack of compliance policies, it's no wonder you dread the prospect of an IT audit. The first step to easing the burden of staying compliant in a virtual world is bringing process and policies to your virtualized infrastructure. If you need help with securing virtual machines, preventing virtual machine security breaches, or guidance with an IT audit management for virtualized resources, this section offers advice, research and tutorials on the discovery and inventory of virtual machines (VMs), tracking and monitoring of VMs to ensure VM security, methods to harden virtual machines, how to create an audit trail of VM changes, preventing software licensing violations, and other guidelines to comply with regulations such as Sarbanes-Oxley Act (SOX), the Health Insurance Portability and Accountability Act (HIPAA) and the Payment Card Industry Data Security Standard (PCI DSS), and more.

Virtualization backup and disaster recovery strategies

With server virtualization for disaster recovery, you can develop a business continuity strategy that includes backup and recovery techniques with virtualized servers rather than dedicating idle physical servers to backup tasks. In addition to reducing hardware costs and data center footprint, using server virtualization as part of your disaster recovery strategy can improve system uptime and recovery time objectives and recovery point objectives as well as ensure the integrity of the data you retrieve. Using virtualization for disaster recovery can also help with testing and development of your recovery site. In this section, we offer resources on server virtualization for disaster recovery and provide tutorials on requirements and best practices for creating a disaster recovery site with virtualization, the pros and cons of backup techniques such as file-level versus block-level deduplication, snapshotting, using golden images to restore data, failover technologies, the pros and cons of Fibre Channel versus iSCSI storage area networks (SANs), the advantages and disadvantages of hosted disaster recovery services, and more.
