  Security needs monitoring to function

  Publié: mai 4, 2016, 11:29am CEST par Dirk Paessler

  IT trends often come and go, some dominating the hype cycle for years, others exiting the mainstream with more of a whimper. Security is having a moment right now in which it is dominating the market in terms of press, thought leadership and excitement. But, in this case, it’s no trend, it’s reality. As long as there have been networks, there have been concerns over security. That is true now more than ever, as networks have grown larger, more complex, and crucially, more critical to business function. In 2015, Paessler AG conducted a survey that found 58 percent of IT… [Continue Reading]

  Cloud computing and the true future of networks

  Publié: août 11, 2015, 7:38pm CEST par Dirk Paessler

  

  Cloud computing, network virtualization and on-demand technology services are changing how we think about IT.

  If these new services become as ubiquitous as predicted we could see companies accessing their IT services remotely, at the expense of their own IT infrastructure and applications. If this happens, the thinking goes, the importance of the Local Area Network and the IT administrator could diminish as well.

  It’s not worth saying the last rites over the LAN and IT administrator just yet, though. There’s no denying that times are changing and the increasing use of cloud computing will mean a shift in ICT practices. Cloud allows flexibility, efficiency and can be employed for so many tasks that we will certainly see a transition on some level. But arguably the uptake of cloud will not be on the scale, or at the speed, that is predicted. Nor will it fundamentally change the IT administration role in the way that some assume.

  Firstly, a cloud system is totally dependent on a stable internet connection and is still reliant on the LAN to operate. If a business loses its internet connection for any reason, the entire business will grind to a halt, with even printers unable to function because you won’t have access to the cloud app that sends the file to the printer service.

  Secondly, cloud computing -- and the internet itself -- hinges on the millions of switches, servers and firewalls located across the world. So, organizations will still rely on LANs and continue to demand high availability and fast response times.

  Also, there are some companies for whom the cloud simply isn’t applicable. More than a third of the world’s GDP is produced in non-service industries.

  These companies that manufacture and rely on machine power simply cannot move to the cloud because the high availability that an assembly line demands is not yet provided there. Machines need to be connected by a local area connection with ultra-high bandwidth and solid security, as well as reliability in the four to five-nines range.

  There is a theory that IT administrators will soon become redundant, ready to be moved in all their functions to the cloud -- so-called "service as a service" (SEaaS). The idea is that their role would be filled by remote managers who could take over the day-to-day roles like setting passwords, inducting new users and so on with a cloud app. However, this is unlikely. Cloud services are certainly suitable for the more basic tasks, but they couldn’t replace the more technical on-site jobs that require specific expertise and information-based human intelligence.

  While cloud computing is undeniably a good tool for increasing efficiency of IT administration, the LAN is not going anywhere yet. And if the LAN is staying, so too is the IT administrator and all their associated monitoring tools that help them do their job will continue to play a crucial role in its maintenance, improvement, economic viability and availability. Meanwhile, we’re in an age when other innovations are of equal and possibly greater importance than the cloud -- the internet of things will have a greater impact on the way the office network operates.

  These advances will need efficient networks and network administrators to maintain them. It seems likely then that the network, the administrators and the network-monitoring tools on which they depend are here to stay.

  If anything their expertise is going to be even more in demand as the complexity and diversity of the network continues to grow.

  Using monitoring to increase productivity

  Publié: août 6, 2014, 1:16am CEST par Dirk Paessler

  

  As the global recession recedes, economists are still puzzled by lagging productivity. Despite all the signs of recovery, workers are still producing less output per hour than they were before the crisis; robust economic growth will not return until productivity increases. IT’s role in driving growth has been considered in depth. The consensus is that increased investment in technology will help deliver much-needed boosts in productivity.

  A study by the Center for Economic and Business Research has shown that since the 1970s, technology has increased the efficiency of office workers by 84 percent. Now, with businesses leaving years of uncertainty behind, investment in IT is beginning to pick up again. The most recent Gartner Worldwide IT Spending Forecast showed that global spending on IT devices will grow by 4.4 percent to some $689 billion this year. With this new technology, we should see productivity begin to increase.

  However, businesses can improve productivity without purchasing new devices. It’s surprising how much you can achieve by improving the efficiency of your existing infrastructure. A network monitoring tool can help by identifying anomalies and bottlenecks that could be slowing down your network or, if left unchecked, grind it to a halt. Another common problem is underperforming devices -- an overloaded server, for example. A network monitoring tool can be useful for analyzing available bandwidth and maximizing data usage, allowing organizations to optimize their IT infrastructure. The bottom line is that it is possible to do more without having to invest in new hardware.

  All businesses will reach a stage where they simply have to invest in their IT to expand. To grow sustainably, businesses need to identify the technologies that will deliver maximum productivity increases, understand how they can best integrate them into their network and how they can be used to increase the efficiency of existing infrastructures. When a company invests in new tools, it expects them to work seamlessly and to see tangible productivity gains immediately. The onus is on the IT professional to make this happen. With a network monitor in their arsenal, potential snags and teething issues can be overcome, so that the value of new hardware is seen quickly.

  Of course, it’s not just hardware that requires meticulous monitoring. Office productivity applications, especially business process management (BPM) software, are increasingly used by businesses. WinterGreen Research predicts the $3.4 billion worldwide market will be worth over $10 billion by 2020 as more and more businesses see BPM as an opportunity to drive down costs and improve agility. With increased dependence on these tools comes increased responsibility on IT departments to keep close tabs on IT infrastructure.

  Looking to the future, innovations in IT hold some exciting prospects. Recent developments such as the Internet of Things promise great productivity gains by offering speedier communications and increased automation. Take the manufacturing sector as an example: the potential for new technology to transform manufacturing is so great that it is now being called "The Fourth Industrial Revolution".

  Siemens is currently developing the factory of the future, where all parts can communicate with one other. The result could be a newly built car talking to the factory. In this scenario, a vehicle could self-diagnose a fault and then signal to the factory that parts need to be made to replace the defective unit and altered accordingly for future models. The possibilities offered by this "revolution" are tremendous, but careful management of the networks on which it will depend will be critical if businesses are to take full advantage. Network monitoring will play a vital role in helping detect faults before they have an opportunity to affect performance.

  Increased automation and reliance on technology in all sectors will demand careful management and an early warning system to ensure smooth operations. As networks become more complicated and interdependent, monitoring will become more crucial. With the up-to-date information that network monitoring provides, IT professionals will be well placed to ensure businesses see a strong return on investment in new technology and experience increased productivity.
