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 large bandwidth. 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.

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.

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.
