Virtualization is moving to the mainstream and may soon be overtaking non-virtualized environments as a method for deploying applications. Does this broad adoption of virtualization, though, make network security easier or more difficult to achieve? While responses to this question are still highly varied, one thing is certain: most companies still have no clear and definite security policy for their virtual environments.
The data center has gone through many major evolutionary changes over the past several decades, and each change has been defined by major shifts in architectures. The industry moved from the mainframe era to client/server computing and then to Internet computing. In 2011, another major shift began: the shift to a virtual data center. This has been the primary driver in enabling customers to transition to the cloud and ultimately IT as a service. The shift to a virtual data center will be the single biggest transition in the history of computing. It will reshape all the major data center tiers: applications, storage, servers and

Today’s workforce is increasingly nomadic. Employees use personal and company-owned devices desktops, laptops, tablets, and smartphones with various operating systems to access corporate resources over different networks from virtually anywhere. Roaming users and cloud-based applications have eroded the network perimeter where enterprises have traditionally focused their security controls.
In the wake of this disruption, vendors offered myriad point products that solve only a portion of the security problem. These products usually require costly custom integrations and high management overhead to boot.
Making matters worse, traditional security approaches can’t address an evolving threat landscape that includes ransomware, stealthy attacks that dwell in a customer’s environment for months, and threats targeting iOS and Android devices. In fact, the mobile workforce is more vulnerable than ever before.
This paper summarizes and evaluates the prevalence and efficacy of data center virtualization deployments, as well as the hardware that supports them. The conclusions drawn from this report are based on analysis of both quantitative market research and two qualitative interviews with a CIO and CTO in healthcare and finance, respectively. Each customer, referred to ESG by Hewlett-Packard (HP), had extensive experience deploying both server and desktop virtualization. The goal of the study was to determine the IT and business drivers to adoption of virtual technologies, the expected and realized benefits, ensuing infrastructure decisions,future outlook of the data center, and best practices for deployment.
HP Cloud Solution for Microsoft is designed to provide a scalable, high-performance integrated infrastructure optimized for virtual environments built on Microsoft Hyper-V. Designed and built according to the Microsoft Private Cloud Fast Track reference architecture, HP Virtual System for Microsoft comes standard with Microsoft Windows Server 2012 (which includes Hyper-V) and is designed to deliver top performance for a wide range of virtualized applications, including Microsoft Exchange, SQL Server, and SharePoint. This paper will focus on ESG’s analysis of the costs and benefits—and ultimate economic value—associated with deploying and managing HP Cloud Solution for Microsoft, versus a comparable conventional data center infrastructure comprised of discreet, non-integrated compute, storage, network, and management components.

IT and Line of Business (LOB) management need precise, comprehensive metrics describing real end user experience, before and after going “virtual”, in order to support strategic desktop virtualization and consolidation decisions.
Businesses are overwhelmed with data; it’s a blessing and a curse. A curse because it can overwhelm traditional approaches to storing and processing it. A blessing because the data promises business insight that never existed earlier. The industry has spawned a new term, “big data,” to describe it. Now, IT itself is overwhelmed with its own big data. In the press to roll out new services and technologies—mobility, cloud, virtualization—applications, networks, and physical and virtual servers grow in a sprawl. With them comes an unprecedented volume of data such as logs, events, and flows. It takes too much time and resources to sift through it, so most of it lies unexplored and unexploited. Yet like business data, it contains insight that can help us solve problems, make decisions, and plan for the future.
To ensure the full potential of your virtual platform solution, you need to make sure your application and storage network is prepared to handle the added stresses of a virtual machine (VM) infrastructure. F5® technology enables your network to adapt to virtualization needs, ensure high availability (HA), maximize resources, and improve performance so you can get the most out of your investment.
The four pillars of computing — cloud, mobility, social, and analytics — are driving new levels of network innovation in datacenter networks. These forces are now buffeting the datacenter along with virtualization and the Internet of Things (IoT), resulting in sweeping changes in traffic patterns that expose the limitations of traditional networks and their operational models. To become a resource rather than a bottleneck to overall datacenter performance, the network must deliver not just exceptional performance and scalability but also unprecedented automation and orchestration that can yield agility, flexibility, and service velocity. This Technology Spotlight examines these key trends and discusses the role that Cisco's Application Centric Infrastructure (ACI) plays in addressing these
ongoing challenges for enterprise IT and network managers.

? Radically simplify management and operations
? Quickly adapt infrastructure to align the data center network with the needs of your business applications,
today and in the future
Virtualization has transformed the data center over the past decade. IT departments use virtualization to consolidate multiple server workloads onto a smaller number of more powerful servers. They use virtualization to scale existing applications by
adding more virtual machines to support them, and they deploy new applications without having to purchase additional servers to do so. They achieve greater resource utilization by balancing workloads across a large pool of servers in real time—and they respond more quickly to changes in workload or server availability by moving virtual machines between physical servers. Virtualized environments support private clouds on which application engineers can now provision their own virtual servers and networks in environments that expand and contract on demand.
As virtualization becomes more pervasive in the datacenter, organizations are deploying complementary types of virtualization technologies. Read this white paper to learn how blending application and OS virtualization using Citrix and Virtuozzo will provide stronger and more robust virtualization solution.
Virtualized Evolved Packet Core (vEPC) is a major breakthrough in network function virtualization (NFV). When
asked where they have deployed NFV in production networks, communication service providers (CSPs) consistently name vEPC as one of the top answers. Why is that?
In order to maximize their processing capacity, CSPs virtualize a subset of their network applications, including
mobile edge computing (MEC), base stations (small/macro
cells) and the mobile core, because these systems use a
The mobile packet core builds the foundation of the core
network on which mobile CSPs offer IP-based services to
their customers. Implementing vEPC solutions can help
CSPs obtain the scale necessary to accommodate growing
numbers of subscribers and large amounts of traffic or
connections while controlling costs and improving on quality of experience (QoE). In the past, evolved packet core
(EPC) solutions were deployed on purpose-built hardware.

The role of IT is fundamentally changing from a cost-efficient enablement technology to a more strategic element of the enterprise. For companies born before the digital era, IT is a key player on their path to digital transformation; for more recent businesses designed with technology at their core, IT represents a foundational pillar on top of which everything else is built.
With this shifting role, IT’s decades-long emphasis on TCO is being eclipsed by a new-found focus on security and automation. Whether it’s the continuous risks posed by a dynamic threat landscape, the threat of digital disruption, or an inability to keep pace with the latest trends, virtually every enterprise needs to be more agile. And, with the continued evolution of compute, storage, and applications, networks have been exposed as a bottleneck to change.
