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.
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.
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.

How to effectively troubleshoot your VDI deployment Virtual desktop infrastructure has come a long way since the first steps were taken a decade ago to run desktop workloads in the data center.
While more pervasive today, VDI technologies are latency-sensitive, and wholly dependent on the network. Complaints of poor end-user experience persist, especially over the WAN at branch offices where bandwidth constraints and latency delays are common.
But there is a way to ensure consistent and reliable VDI performance to deliver:
Enhanced planning and control

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
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.

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.
SymantecTM provides a complete endpoint solution powered by the world’s largest civilian Global Intelligence Network (GIN) to help organizations secure their enterprise and mobile workforce across traditional and modern OS devices used over any network and from any location.

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

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.
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.

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.
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.
"As the rapid rise in the number of mobile devices and users creates an explosion in data and virtual machine instances, datacenter transformation becomes imperative for many enterprises. It is essential enterprises move to consolidate resources and cut both capital and operating costs while still providing support for distributed applications.

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.
