2 VIRTUALIZATION What is virtualization? Virtualization is the creation of a virtual version of an operating system, server, storage device or network resources. Operating system virtualization allows multiple operating systems and applications to run on the same server simultaneously. Network virtualization combines all of the available resources in a network by splitting up the available bandwidth into channels, independent of each other, that can be assigned or reassigned to a specific server or device in real time. This type of virtualization technology is similar to partitioning a hard drive to manage files easier. Storage virtualization assembles physical storage from numerous network storage devices into what appears to be a single storage device that is controlled from a central console. SANs (storage area networks) typically utilize storage virtualization. Server virtualization is the partitioning of a physical server into a number of small, virtual servers using virtualization software. The virtual servers can each run multiple operating system requests at the same time. Virtualization technology has been around for decades and is very popular in the IT industry. Virtualization is changing the very nature of IT architecture and the way people and businesses use the technology around them. This paper will focus on the top three brands of virtualization software available today. Those brands are VMware vSphere, Microsoft Hyper-V, and Citrix Xen. I will compare and contrast them as well as examine the major pros and cons for each brand. This paper will explore the major advantages and disadvantages the organization may experiences when using virtualization software. Top Three Virtualization Software Brands The top three brands of virtualization software available are: 1. VMware vSphere 6 – The industry-leading server virtualization platform has a variety of different features. The vSphere ESXi hypervisor is a bare-metal hypervisor that installs

Compose an executive summary highlighting the paper’s contents and reasoning for your chosen topic. Domain Name System Security Extensions, DNSSC, is a tool employed to aid in the security of the internet by preventing DNS protocol attacks. DNSSEC provides origin authentication of DNS data, data integrity, and authenticated denial of existence. I’ve chosen DNSSEC as my topic because I think security at all levels is important, and I think delving into the specifics of security at the domain name level is worth researching. I also found it interesting in the level of compliance across the globe and even more appalling compliance within united states based companies with this feature of security, which seams so easy to implement, and provide such a great deal of protection for clients, consumers, and others who would require the use of DNS for ecommerce and internet surfing. DNSSEC was introduced in 1990 when the major flaw in DNS was discovered. Immediately steps were taken in attempts to secure DNS interactions. However, it wasn’t until 2011 that DNSSEC was actually employed on US .gov registry through the company Verisign. DNSSEC requires that the root zone files be signed in order for them to be validated. There are four major entities that manage the root zone files:  ICANN – not-for profit Corporation contracted by United States Department of Commerce  National Telecommunications and Information Administration – office within United States Department of Commerce  VeriSign – United States based for-profit company contracted by US Government  An international group of root server operators
