Increasingly enterprises are moving more mission-critical work to public clouds. To make this work well, and securely, though means devising a thorough IT plan for cloud networking. It takes more than just having a robust Internet link -- it takes a robust plan for ensuring communication among the diverse element of your network's service delivery environment. This three-part guide looks at the current considerations when it comes to networking in the cloud. The first chapter examines the limits of the traditional WAN, explores the idea of a virtual WAN and the software-defined WAN, and considers the concept of the network as a service. Other chapters consider the history of the cloud and its impact on the network; cloud as a replacement for the local service and virtual machine, and security issues like the danger of shadow IT in the enterprise.
The variety of ways to deliver network services is expanding. What must come first, though, is a plan that considers your enterprise goals and relevant security considerations.

In today's competitive world, application performance is more important than ever. Enterprises are relying on a new generation of tools designed to let them diagnose application performance management issues -- identifying whether performance problems stem from the network or the application itself. As mobile and the cloud become more pervasive, engineers and network administrators are also using APM platforms and software to ensure that voice, video and data traffic meet strict performance guidelines.
This technical guide reviews the key features enterprises need in their application performance management (APM) tools. These tools today must be able to cope with a hybrid service-delivery environment that is heavily dependent on east-west flows among clouds of service components. To do this requires that the tools be located near the services; this guide explains how to accomplish that, and also reviews other key features of modern APM tools. In addition, other chapters delve deeply into what can go wrong in app performance and ways to troubleshoot when they do.
In this guide, networking pros will find answers to many of their app performance problems, as well as detailed, actionable advice.Continue Reading

Network engineers have long suffered the consequences of slow provisioning times for many traditional wide area network (WAN) connections like point-to-point T1 lines or MPLS networks. They're at the mercy of carriers that can take as long as three months to install these services.
It's a longtime challenge that has, actually, not gotten worse over time. Provisioning lead times has gradually shortened over the years.
But, as we explore in this issue of Network Evolution, enterprises today are feeling the consequences of these delays more acutely. That's because IT departments are under increased pressure to make sure their infrastructure is agile and dynamic in the face of ever-changing demands. Real-time provisioning in other areas of IT, such as server virtualization, has also exposed the WAN as an obstruction to innovation at times.
In this issue’s cover story, we speak with network engineers who make sure they're always ready with a "plan B" if the business' needs are outpacing the time it takes to install a new WAN circuit or add more bandwidth to an existing one. Meanwhile, carriers are getting serious about using software-defined networking (SDN) to reduce WAN provisioning times. We talk to one service provider that claims customers in its SDN pilot program can adjust bandwidth on a WAN circuit with a few clicks -- without any human intervention from the carrier -- and see the changes live on their network within minutes.
Also in this issue, we look at an emerging trend around video conferencing analytics -- a capability that some enterprises use to get the most out of their video conferencing deployments. These tools look at usage and performance of video equipment, cluing in IT professionals as to whether a dedicated video conferencing room might be better off as an all-purpose conference room, or vice versa.
Finally, this issue of Network Evolution dives into the wireless networking skills gap that many engineers face, due to the lack of wireless-intensive training in college-level IT courses and similar settings. And as wireless becomes a pervasive and primary means of connectivity for more enterprises, network engineers need the right skills to keep up. Continue Reading
