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.
Client virtualization technologies are redefining the way IT resources are
delivered to end users, and creating exciting new opportunities for IT
organizations as they work to streamline and improve operations. By
abstracting applications and operating systems from client hardware,
virtualization enables client assets to be stored on central servers and
delivered to client endpoints.
The implications are profound. End users can log on to any networkconnected
computing device and access their custom operating system
and application environment. For IT departments, central management of
client virtual machine (VM) images brings efficiencies in everything from
routine maintenance and updating to operating system upgrades.
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
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.
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.

New business demands and technology trends are changing the role of IT and introducing new challenges to
application availability that yesterday’s data centers were not designed to address. By upgrading to Cisco Nexus®
switches—purpose-built for today’s data center needs—you can:
? Increase performance and scalability to meet the demands of virtualization, cloud computing, and modern
? 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
Download this white paper to see why securing the data center requires a solution that can:
-Provide visibility and control over custom data center applications
-Handle asymmetric traffic flows and application transactions between devices and data centers
-Adapt as data centers evolve: to virtualization, software-defined networking (SDN), network functions virtualization (NFV), Cisco -Application-Centric Infrastructures (ACIs) and beyond
-Address the entire attack continuum: before, during, and after an attack
-Integrate with security deployed across the entire network
-Support geograpically dispersed inter-DC traffic and deployments, including private, public and cloud environments
The Secure Data Center is a place in the network (PIN) where a company centralizes data and performs services for business. Data centers contain hundreds to thousands of physical and virtual servers that are segmented by applications, zones, and other methods. This guide addresses data center business flows and the security used to defend them. The Secure Data Center is one of the six places in the network within SAFE. SAFE is a holistic approach in which Secure PINs model the physical infrastructure and Secure Domains represent the operational aspects of a network.
The world of IT is undergoing a digital transformation. Applications are growing fast, and so are the users consuming them. These applications are everywhere—in the datacenter, on virtual and/or microservices platforms, in the cloud, and as SaaS. More and more apps are now being moved out of datacenters to a cloud-based infrastructure.
In order for an optimized and secure delivery of these applications, IT needs specific network appliances called Application Delivery Controllers (ADCs). These ADCs come in hardware, virtual, and containerized form factors, and are sized by Network Administrators based on the current and future usage of applications. The challenge with this is that it’s hard to foresee sizing or scalability requirements for these ADCs since users are constantly increasing, and applications are consistently evolving, as well as moving out of datacenters.
Complicating matters, most ADCs are fixed-capacity network appliances that provide zero or minimum expansion capability
It’s a transformative time in government information technology. Public sector organizations are moving to the cloud. At the same time, seemingly everything that can be virtualized is quickly heading in that direction. Immersive Web applications are enabling next-generation services, including innovative mobile apps that give agency staff members and constituents anytime access to valuable resources. Video seems to be everywhere, with one research firm estimating that video streaming accounts for more than 53 percent of all downstream traffic in North America. In this white paper from the Center for Digital Government (CDG), we break down what every IT leader needs to know about today’s networking to ensure project success.
F5 pioneered the concept of breaking up data center virtualization technologies into eight unique categories within the data center. Any virtualization products or technologies implemented in the data center will fall into one of these eight categories.
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.
VMware Infrastructure products provide the next generation virtual platform for the new data center, but they don’t virtualize the network or application delivery. F5 BIG-IP LTM works with VMware to provide truly virtualized Application Delivery Networking.
Efforts to reduce capital and operating expenditures by consolidating data centers can fail if applications and network are not optimized. Learn about a consolidation strategy that goes beyond centralizing servers, routers, software, and switches to solve multiple business problems.
Virtualization was supposed to be the disruptive technology that saved IT. The cost savings from consolidation and the ease at which applications can be deployed promised to vastly improve delivery of IT services, free up IT staff to work on other projects, and not strain budgets.
Unfortunately, lack of insight into IT resource status in highly virtualized environments and the complexity of the interactions between server, storage, and network elements have added to IT staff manual workloads and led most companies to dedicate too much time to operations and not enough time to innovation. This basically negates the major benefits of virtualization.
"Cloud computing, also known as 'IT as a Service', is predicated on delivering IT services on demand, an idea that has support from business leaders as a way to better align IT with business operations. Cloud computing has two key requirements: virtualized applications and seamless support and integration between the server, networking, storage and hypervisor components.
In this paper, we explore these concepts and highlight the critical features necessary to move beyond server virtualization by leveraging key integration capabilities between IT components-with a particular focus on the important role that storage plays in the evolution of the datacenter architecture."
