Delta Airlines lost millions of dollars this week, according to Wall Street Journal report, all caused by a single networking device problem (reported as “switchgear problem”). The early measurements of the cost of the outage is not taking into effect the bad publicity and PR this created as well as the bitter taste for passengers who had to miss their flights and in some case had to sleep at the airport overnight. Business continuity, in today’s world is a not a luxury, but a must-have.
If the business relies on services that are mission critical and can’t afford downtime, a modern management of networking is required. This applies both for Local Area Network (LAN) of the organization, as well as the connectivity of the organization to the larger Internet, namely, the Wide Area Network (WAN). In today’s connected business world, mission critical applications are no longer limited to a few specialized industry specific services, but rather covers everything from phone systems, to security, to access to corporate data – in other words, it covers the core components of the business operations. That’s why business continuity can not be an after thought, but needs to be designed into the architecture proactively.
Data centers are a microcosm of this larger problem, where services and connectivity live within an restricted space. Downtime, configuration errors, and device management problems lead to a brilliant networking solution known as Software Defined Networking or SDN, whereby a software driven management, configuration and monitoring is targeted and therefore taking out any human errors out of the picture. Overlaying special network functions (known as Virtual Network Functions) on can overlay redundancy, self-healing and auto-recovery aspects into the data-center with relative ease. Virtualization of servers and storage elements had the same design goal, where redundancy and auto-failover is designed in, as opposed to a reactive approach.
Similarly, for the Wide Area Networks, a Software driven resiliency approach is possible with SD-WAN (Software Defined WAN), whereby software driven algorithms and functions called Virtual Network Functions (VNF) can be overlaid on top of the real WAN connection and therefore creating a redundancy and self-healing for utmost business continuity.
