A New World of Performance
After suspecting that its domain name system (DNS) was underperforming, TalkTalk turned to Splunk to bring data to questions and decisions around its existing system. Thanks to Splunk technology, TalkTalk identified the root problem, which enabled the team to present a data-supported business case to replace its entire DNS platform. This success unleashed new possibilities for the TalkTalk team, raising the question of what other problems Splunk could help solve. “We started to feed data into Splunk and then, just like magic, we now have this great world of performance driven largely by Splunk,” says Paul Emmett, head of network operations.
Having operated a network operation center (NOC) for years, TalkTalk monitored network services in a traditional way, yielding what the company termed “binary measures of network performance.” Yet with Splunk Enterprise in place, TalkTalk united these metrics to gain a better understanding of service performance as a whole. For Matt Wood, the company’s head of labs, the Splunk platform’s ease of use, rich functionality and wide availability of apps stood out the most. “It’s very easy to use. You can just dive in,” he says.
