Network infrastructure is evolving at an unprecedented rate and, with mixed vendor environments the norm rather than the exception, management of those systems has become a labour intensive exercise. Unlike fault and performance management, Network Change and Configuration Management (NCCM) has no common harmonised management method or protocols; Even the first level engineering teams have to be proficient in numerous different configuration languages and interfaces for the simplest of tasks. In...

As IT environments become more complex, so does application performance management. IT professionals need tools that are up for the new challenge. "Applications are becoming increasingly difficult to troubleshoot, and [it's becoming more difficult to] understand how users are interacting with them," said Jonah Kowall, research vice president of IT operations management at Stamford, Conn.-based Gartner Inc. "Because applications are so diverse, there are a lot of different approaches and solution...

In managing network performance, user experience takes priority. Being proactive in managing performance means not only tracking the network and application, but obtaining an in-depth view of the underlying infrastructure health. There are two primary ways to obtain this information: agent or agentless. Selecting the best method for your team requires understanding the options and selecting the solution that integrates well with your existing resources. This IT Brief will: Define agent and agent...

Despite worries about social media, most companies are not monitoring it for threats While businesses continue to expand their use of social networking to manage their brands and increase productivity, only a minority of firms are attempting to offset the risks posed by these services. The lack of focus on securing social networking is leaving companies vulnerable, say security experts. Only 18 percent of companies do a risk assessment of their use of social media, even though 84 percent worry a...

The Coming Wave of IP-based Live Videoconferencing The future of all telecommunications is undoubtedly IP-based. Voice over IP (VoIP) is now considered mainstream within enterprise organizations, and a growing number are embracing the next phase of this evolutionary track by deploying IP-based live video communications. IP videoconferencing has strong appeal – it can effectively deliver ever-important direct and interactive human communications that typically occur only during face-to-face meeti...

Over the past few years, organizations worldwide were forced to deal with an IT “problem” referred to as BYOD (Bring Your Own Device). It started with smart phones, and now it’s occurring with other devices as well. Here’s what happened: Most large organizations, as well as midsize and even smaller ones, required their people to have a Blackberry. By combining a cell phone with a secure, enterprise level email system, Blackberry changed how we use cell phones and took mobile working to a new lev...

There are several solutions out there for businesses to leverage, eac...

It’s that time of year again – when we all look back as well as forward, regret the things we haven’t done, then promise to make them right once more. Instead of doing the typical forecast and prognostications that most analysts pump out this time of year, I prefer to take a different tact – to simply raise attention regarding the things we know we should do in network management but really haven’t got around to doing yet. Based on the research that I’ve done in the past year as well is that I p...

Employees' new mobile devices could cause the age-old security versus productivity debate to resurface Christmas is fast approaching. Now, and after the office is back to normal after the first of the year, employees are going to return with several shiny new gadgets, along with the expectation that they'll "just work" in the corporate environment.
