Roland Mestric , Head of Marketing for IP Network Automation , Nokia , tells us how achieving reliable data centre networks demands a new approach to building and managing networks . he phone rings in the middle of the night ,

You join the bridge , while you are digging around device logs , looking for the source of this chaos . It feels like hunting for another needle in this haystack of hell . Then you hear the chime of someone new joining the bridge . A junior engineer , trembling at the gates of judgment , eeks : like hybrid cloud and on-premises environments , in addition to the integration of legacy hardware .

Ensuring there is consistent connectivity , enforcing security policies and maintaining smooth data flow between cloud providers and on-premises systems is increasingly difficult . Adding

“ I applied a change , thinking it wouldn ’ t have any impact . . . ”

It is the beginning of a long , stressful night of troubleshooting and firefighting .

This scenario is all too familiar for many data centre network engineers .

Why do data centre networks break so often ?

According to the Uptime Institute , human error is the root cause of up to two-thirds of data centre infrastructure downtime , highlighting a critical vulnerability that must be mitigated in an era where cloud-based applications and services are the backbone of the global economy .

These human errors can include misconfigurations , improper policy updates , insufficient pre-production testing by network operators and accidental input errors as a result of misunderstanding or ‘ fat fingers .’

The growing complexity of modern networks adds to the challenge . In data centres , this complexity stems from factors
