When it comes to cloud watching, you’re probably thinking that means laying outside in the sun watching clouds float by. That is a form of cloud watching, yes; however, the type of cloud watching I’ll be talking about today is monitoring your network clouds with NetFlow!
Monitoring network traffic to CDNs (content delivery networks) is becoming network engineers’ and network admins’ nightmare. Since a lot of social media and even malware are being hosted on these large cloud servers, host reputation (typically done with IP information) is in most cases becoming obsolete. In this blog I will show you how using our NetFlow probe and our advanced DNS analytics provides insight into encrypted CDN traffic. Read more
Big data is popping up in all things IT these days. It impacts a good percentage of business applications across all verticals from government to healthcare to media, and no surprise, it can have a significant impact on network performance as well. More and more companies are collecting huge volumes of data—terabytes or even petabytes—from their network every day, and these volumes are expected to continue to increase. IT teams need to figure out not only how to store big data, but how to recall and analyze it so that it can be put to good use. Read more
Most companies ask about security before outsourcing to a cloud service. The problem when asking this question is that, many of us don’t really question or test the claims of what the vendor tells us. Why should we, vendors are honest …..right?
With the growing number of cloud services and applications, companies are becoming more concerned about these applications absorbing their Internet connections. This is creating a need for improved cloud service monitoring solutions. IT departments want to know how they can reliably monitor these applications and answer questions such as, “how much bandwidth is each application consuming?” or “why is performance poor?” The infrastructure needed to answer questions like these are already in place on most networks, but it can’t be done with SNMP, ping utilities, or packet probes as these solutions don’t scale. We need to take advantage of a smarter, deeper analysis, architecture and we need to know how to leverage it. Allow me to reveal five best practices for: Read more
