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.
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.
NFV enables operators to deploy EPC c
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

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.
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.

The constant growth of cloud, IoT, virtualization, mobility, and digital transformation has brought tectonic changes to the world of networking. Long viewed as a bastion of single-purpose, inflexible, and closed solutions, networks have started to transform in line with the demands for flexibility, scalability, ease of management, interoperability, and application support. Networking departments need to achieve all of the tasks above while keeping costs under control. Additionally, security requirements for the new network are not letting up — quite the opposite, as the virtualized network (and general IT) environment requires rethinking, virtualization, and evolution of security architectures.
Service virtualization offers a solution. Service virtualization tools simulate software components so end-to-end testing can proceed even when dependent components are not available. That means teams can perform integration tests sooner and more often, accelerating the delivery of high-quality, thoroughly tested applications.
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.

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.
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 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 the network.
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.

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.

Organizations have gained significant benefit from virtualizing servers and storage environments, and now face the daunting task of deploying new network architectures to keep pace. Software-defined networking holds significant promise to deliver a new network architecture that is abstracted and virtualized; however, organizations would be well served to learn from previous efforts to virtualize other domains in order to avoid making the same mistakes. Riverbed and VMware joined forces to help eliminate those problems and make it easier to deploy VXLAN overlay networks in highly virtualized data centers by integrating application-aware network performance management software and vSphere 5.1.
