Cloud is a rapidly emerging necessity in IT. Relied upon the world's largest enterprise data centers and cloud networks, NetScaler is universally recognized as an outstanding application delivery controller. Learn how NetScaler beats the competition.
Business evolution and technology advancements during the last decade have driven a sea change in the way data centers are funded, organized, and managed. Enterprises are now focusing on a profound digital transformation which is a continuous adjustment of technology management resources to deliver business results, guided by rapid review of desired outcomes related to end clients, resources, and budget constraints. These IT transitions are very much part of the competitive landscape, and executed correctly, they become competitive differentiators and enable bottom line growth. These outcomes are driving data centers to virtualization, service-oriented architectures, increased cybersecurity, “big data,” and “cloud,” to name a few of the key factors. This is completely rethinking and retooling the way enterprises handle the applications, data, security, and access that constitute their critical IT resources. In essence, cloud is the new IT.
As IT becomes the cloud, and ever more central to business success, projects to transform the IT systems, and more specifically the data center, have become strategic and a competitive differentiator. A crucial piece of the data center transformation puzzle, and one which is too often left until the end, is the network. As the central nervous system of the data center, its transformation must be an integral part of the entire data center transformation project.
Getting your applications to work properly over a Wide Area Network (WAN) is a complex task, and it is not likely to get easier any time soon. Trends such as data center consolidation, the advent of Web 2.0 applications, and the move to web-based application delivery have only served to increase complexity and slow user response times. Often, the result is sluggish application response and at worst, abandoned applications and shopping carts due to slow or failed web page loads. The good news is that you can do something to improve application performance over slow or congested WAN networks. An Application Delivery Network can accelerate your applications and help make sure they’re secure, fast, and available.
Modern data centers based on hyperscale, leaf-spine switching
architectures are growing so large and complex they are outstripping the
capacity of operators to engineer, configure and manage these networks
using traditional tools and techniques. As a result, data center operators
are looking for new ways to automate workflows, maximize uptime and
increase operational agility while reducing operating costs
Cisco ACI, the industry-leading software-defined networking solution, facilitates application agility and data center automation. With ACI Anywhere, enable scalable multicloud networks with a consistent policy model, and gain the flexibility to move applications seamlessly to any location or any cloud while maintaining security and high availability.
Departments of roads and highways around the world have begun to implement technology solutions to improve the safety of their highways, lessen congestion and manage traffic more efficiently. Intelligent Transport Systems (ITS), as these systems are known, require reliable, secure and scalable networks to link cameras, sensors, signage, signaling and vehicles to remote data centers and operation centers.
These networks will be deployed in harsh environments and will pose their own unique challenges to operate, maintain and manage.
In this application note, we will present the unique requirements of ITS networks and discuss how AlcatelLucent Enterprise products and technologies not only meet today’s ITS requirements, but are designed to grow and scale to meet tomorrow’s as well.
Server virtualization initiatives are reshaping data center traffic flows, increasing bandwidth densities at the server edge and pushing conventional data center networks to the brink. This white paper reviews the impact of server virtualization.
This white paper reviews the impact of server virtualization on the data center and describes a simpler way to build more secure and automated networks that fully meet the stringent performance, availability, and agility demands of data centers.
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.
A five-year-long quest for software-defined application delivery and services came to a fruitful end for this $4 billion enterprise when they chose Avi Networks and Cisco ACI as part of their move to a next generation data center architecture. Avi Networks represented the perfect complement to the network automation benefits delivered by Cisco ACI at the company.
IT has gone through a significant evolution over the past decade. Virtualization has changed
the entire face of the data center, the network edge has become predominantly wireless and
consumer devices reign supreme. However, one of the few areas of IT that has yet to evolve is
the corporate wide area network (WAN). Managing the WAN is something network managers
have always struggled with because WAN speeds are typically an order of magnitude, or more,
slower than local area networks (LANs).

When data center technology such as servers or storage area networks are aligned with specific applications or organizational departments, the result is often inefficiency. Through data center convergence, IT resources can be managed more easily.
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.
