As we look ahead, here are key trends we expect to continue over the course of the next few years in APM and NPM. Some of these we’ve already covered earlier in examining the evolution of APM and NPM but they bear re-iterating because of their importance.
- The impact of the Cloud – The ascent of the Cloud has altered the landscape for both applications and networks, with virtualization providing significant operational and cost advantages. 451 Research estimates for cloud adoption of enterprise workloads to be approximately 40%, with even faster growth for public cloud services, including serverless models. Rapid growth of containers, fueled by the open source community (i..e, Kubernetes) is driving down costs even faster. Consequently, ability to be able to monitor services in opaque environments is becoming essential. As well, as clouds provide their own integrated monitoring capabilities, end-users are faced with the question of whether to rely solely on these tools, or how best to integrate this set of external monitoring data into a unified pane of glass and how to verify the accuracy of such
- Dynamic Services pose a new set of challenges – Moving away from static services necessitates a rethinking of how service delivery can be validated, along with a new set of KPIs. Monitoring dynamic, short-term services remains a challenge, considering the traditional reliance on historical
- Overlays impose complexity – Overlay-based SDN complicate monitoring, because monitoring tunnels (encrypted and otherwise) requires specialized management tools and often integration with the vendor devices to get maximum visibility.
- Video is taking over – According to the 2017 Cisco Visual Network Index over of the aggregate internet traffic is video, with a projection of 80% by 2021. This has fueled a major capacity expansion at fixed and mobile operators, along with increased bandwidth consumption by enterprise and residential customers. Non-real- time video is rapidly growing in the workplace, as employees participate in meetings/conferences online, watch training and informational videos, along with new employee onboarding, to name a few popular applications. Residential consumers are increasingly cutting the cord, generating over 60GB per month per household for entertainment video and audio from many OTT providers. In Q2 of this year, major operators lost almost 1 M pay TV subscribers. The challenge remains how to deliver high-quality video at the lowest cost as the pressure is mounting to reduce recurring monthly fees. Monitoring tools need to become content- and context- aware, able to handle the large number of packets going through while providing an application and end-user viewpoint of the QoS, which can be very specific in the case of video
- SDN and NFV are Rapidly Emerging– SDN and NFV are turning the industry upside down as our SDxCentral audience are well-aware. NPM and APM, not to mention the entire network management industry are not immune from the disruption. The integration of monitoring solutions into SDN and NFV infrastructure will take thought and effort.
