FEATURE AUTONOMOUS VEHICLES ARE A HOT TOPIC AND THE SAME WILL BE TRUE IN NETWORKING. outside world can push you into day two if you won’t or ‘The can’t embrace powerful trends quickly. If you fight them, you’re probably fighting the future. Embrace them and you have a tailwind.’ – Jeff Bezos. When you are driving a car, do you watch the road ahead, or the dashboard? The answer is that you watch both, of course. But you watch them in a different way. The dashboard supplies numeric data, including historic data – how many miles you have travelled – and current data about things like your speed, fuel levels and engine revs. All of these are useful. Some are critical, but taken for granted: few people bother with engine temperature unless a warning light flashes. But none of them are particularly relevant to the driver’s intention. The intention is typically to reach a destination, rather than to drive at 60 mph and keep the engine at the right temperature. (Though traffic police do hope that a part of the intention is not to exceed speed limits). Watching the road ahead is much more closely aligned to intention. We are looking for familiar landmarks, road signs indicating where to turn off, information suggesting how many miles to go. But we are even more alert to one overarching but unannounced intention: not to crash. Any obstacle, person or vehicle is suddenly in the way and we will instinctively swerve, brake or accelerate to avoid it. The interesting thing is that these responses are largely automatic – they happen before we even have time to think. Very different from the slower way we respond to the dashboard. ‘Going 55 in a 40 mph zone – I’d better slow down a bit’. ‘Gas low – better keep my eyes open for a fuel station’. Driving operations So, how do we compare driving cars and driving business operations? Operation teams are typically notified of performance or availability issues after they’ve occurred. It is important to know that last quarter was down 5% on the previous quarter, but the damage has already been done. We need visibility into what is happening now – so we drive by the dashboard, monitoring systems to ensure they’re within acceptable thresholds. After over 20 years of monitoring best practices to respond to outages and events, we are biased towards reducing outages and problems, rather than having our eyes on the road ahead and focusing on actual business objectives. Staring at dashboards, likely designed years ago under different circumstances, is not an effective way to manage and debug an operation. Dashboards introduce a passive approach to consuming data that someone decided was useful from a previous problem. We use this data to look for clues or danger signs rather than looking ahead to make sure that the network is meeting business objectives. Operators would do better to monitor the network proactively to ensure that it is meeting the business needs. Organisations are embarking on complex initiatives that include cloud, Edge and cloud-native application deployments. As a result, operational teams have to support very complex and dynamically evolving projects. In the past, organisations added to their existing monitoring tools and processes another monitoring solution, or dashboard, for each new initiative. Typically, the vendor suggests the monitoring tools for their particular solution. In this way, the operation team builds up an ever more elaborate dashboard, relying on many different tools while trying to make them work together – at a time www.intelligentdatacentres.com Issue 18 45
