Since the early days of systems administration, a god has hovered over server rooms: uptime. uptime tells us how long a server has been on, which indirectly indicates how long it has been since it had a problem requiring a reboot. Operating systems have always had commands to display server uptime, figures that, indirectly, were also indicative of how good a job the administrators were doing. But the gods aren’t eternal; they are outdone, or simply replaced, by other gods. The time must come for even uptime to fall.
Very rarely do leading technology companies and professionals get the chance to see how societal changes impact the core of our business. In this sense, we cannot help but notice how our connectivity paradigms mirror the human sphere of our society. Trends in technology are often influenced by the changes that shape our world and social environment. Here, I would like to take a moment to talk about the late philosopher and sociologist Zygmunt Bauman, who coined the term “liquid modernity” to describe our ever-changing society (characterized by globalization, individualism, and communication and information technologies).
Application-Aware Routing is a change to the way we think about how data packets should be routed through an IP network and is closely related to SD-WAN, Policy-based routing and the use of SLA’s – Service Level Agreements.
Some days ago, I had the chance to go to the annual SD-WAN Summit, an event that has been held in Paris for the last 3 years. It is a great opportunity to learn about state-of-the-art solutions and share trends on wide-area network connectivity, since key industry players were present: manufacturers, carriers, analysts, researchers, and large companies with ambitious communication requirements. Attendance figures show that the event has quickly become the main meeting point to discuss SD-WAN technologies (i.e., more than 450 participants from 31 countries attended the 2017 edition).
For more than a decade now, hardware virtualization technology, more commonly known as virtual machines, has been the technology on which the production systems we know and use today in our information society have been based, and has made – in the midst of an economic crisis – the evolution of Internet-connected software and services profitable and sustainable.
