As a business grows, its network expands in size and complexity. Increasing convolution impedes network management leading to unanticipated outages. Most businesses can't afford such unplanned downtime owing to the staggering overheads that come with it. Also, increase in network size makes it harder to troubleshoot faults as fault isolation becomes cumbersome.
