IDG Contributor Network: 6 key themes shaping the future of network performance management

Description:

1. New types of IT initiatives are influencing network management priorities

In previous years, server virtualization reigned as the number one driver behind network decision-making by a wide margin. In fact, nearly half (49 percent) of IT pros reported it as their top initiative in 2016. This is simply no longer the case in the 2018 study, just two years later.

According to EMA, software defined data centers (SDDCs), public cloud or infrastructure as a service (IaaS), and private cloud initiatives are now the most influential drivers behind network management decision-making. This shift makes sense. As these technologies add a host of new efficiencies and complexities to the network management processes, enterprises will require solutions that can provide a holistic, deep view into network performance.

As network complexity grows, so does the complexity of understanding and resolving performance issues. A single transaction can take a round trip through wireless, wired and virtual networks, ending up back at the origin. Only with visibility into every segment of network transactions as they traverse physical networks, virtualized environments, and the cloud can we effectively identify, troubleshoot and resolve network issues, regardless of their origin.

2. Cloud services are flooding enterprise networks, presenting monitoring challenges

As cloud adoption grows, its impact on the network continues to be a significant focus area for IT decision-makers. When asked which types of workloads are most present on their networks, 60 percent of EMA survey participants identified external public cloud traffic as most prevalent, estimating that nearly half (45 percent) of their total network traffic volume can be traced back to the external cloud.

Network performance monitoring and management can be a challenge in the midst of cloud saturation, especially without the necessary visibility. As a matter of fact, just 15 percent of network managers reported that they are able to oversee cloud networking with existing solutions alone. Why? Most network management solutions aren’t built to do it at all. Nearly 60 percent say that they need to attain some new monitoring and troubleshooting tools for cloud services, while 14 percent are currently still on the hunt for the right solution.

The appropriate kind of cloud visibility solution depends in large part on what the cloud is being used for. A Software-as-a-Service (SaaS) functions may require monitoring service levels from the outside looking in, whereas Infrastructure-as-a-Service (IaaS) platforms such as AWS and Azure may be best monitored alongside the applications they are running for you. One thing’s for sure – the advent of cloud services has stirred up an undeniable need for better insight into performance across hybrid environments.

3. Patchwork management solutions plague NetOps

One of the top NetOps challenges in 2018 is fragmented management solutions. Nearly one-third of IT teams are using 11 or more active tools to monitor and troubleshoot their networks. Eleven!

Nearly half (49 percent) are using between four and 10 tools. Naturally, those network teams that rely on a crowded roster of solutions are less likely ...
