\Welcome to SolarWinds blog series “Diving Deeper with NetFlow – Tips and Tricks”. This is the third part of the 6 part series where you can learn new tips by understanding more about NetFlow and some use cases for effective network monitoring.


In the previous blog, we had discussed about Network Anomaly Detection and how NetFlow helps network administrators analyze and monitor network traffic efficiently. In this blog we will dive into the impact of cloud applications on networks and how you can track your cloud performance while effectively monitoring your network.


The growing demand of cloud based applications and its increased rate of adoption despite has resulted in massive pressure on network administrators. It is imperative that enterprises maintain continuous network uptime for necessary operational processes. Any issues with the network or the speed of service may have adverse business effect.


One of the biggest impacts of cloud applications, is on a network’s bandwidth and the Software as a Service (SaaS) based approach means you need to ensure enough bandwidth is available for business critical applications to run uninterrupted processes 24x7. Network downtime may cause operational losses and may affect the organization’s bottom line. Some of the problems that network administrators face when using hosted cloud applications are:


  • Impact on bandwidth by cloud applications
  • Revenue loss if a business critical application is inaccessible
  • Operational loss if a mission critical cloud application is down
  • Bottlenecks in the network
  • Bandwidth hogging by non-business applications
  • Unauthorized protocol and application usage


Ensuring continuous Cloud application usage


Analyzing NetFlow data helps to monitor network performance as continuous uptime is an absolute necessity for the businesses who use or host cloud applications. It is important for network administrators to lookout for bottlenecks, bandwidth hogs, and unauthorized protocol and application priority. NetFlow data carries information on:


  • Cause of traffic bottlenecks
  • Who are the bandwidth hogs
  • Different end points using enterprise bandwidth
  • Applications being used in the network
  • Conversation priority within the network


NetFlow gives network administrators insight and helps them to prioritize hosted applications and deploy Quality of Service (QoS) policies. It provides the means to track the cumulative usage of a given application in an aggregated manner, down to specific regions, if necessary. As a result, the NetFlow information can be used to verify whether the cloud usage behavior matches with your service level agreement by mapping your actual activity between the cloud and your network. Measuring latency is challenging while operating on cloud, by using flow exporters like nProbe you can identify bottlenecks by analyzing the data through NetFlow collectors and demand the cloud provider the promised service.


Using NetFlow Traffic Analyzer, you can monitor real-time network utilization and traffic patterns, and understand who or which applications are consuming the most bandwidth thus ensuring it is used accordingly. To learn more about NetFlow, check out our NetFlow V9 Datagram Knowledge Series.
