Wowza published an article differentiating passthrough, transcoding, and full streaming workflows, and how each impacts server capacity for Wowza Streaming Engine deployments. It details how varying hardware component engagement (CPU, GPU, RAM) and streaming variables lead to different stream counts per server. The article concludes by emphasizing the importance of matching the server to the workflow and load testing for accurate capacity estimates.
Understanding the resource demands of different streaming workflows is critical for efficient infrastructure planning and cost management in dynamic streaming environments. As AI integration becomes more prevalent, content delivery networks and streaming platforms must precisely balance compute resources between video processing and intelligent analysis. Companies need to rigorously load test their specific pipelines to prevent over-provisioning or performance bottlenecks, particularly as they integrate advanced features like real-time AI analytics into live streams.
Wowza continues to emphasize the need for optimized server sizing, noting that under-provisioned servers lead to performance degradation while over-provisioning increases costs. A recent Wowza article (October 2026) on video streaming server sizing highlights that factors like resolution, frame rate, codec choice, and protocol directly impact hardware load and must be evaluated alongside hardware capacity. For instance, moving from 1080p to 4K can quadruple per-frame work, significantly impacting GPU load. Wowza's deep integration with hardware like AMD's U30 card on AWS VT1 instances (per a Wowza blog, May 2026) aims to provide high-density transcoding efficiency. This specialized hardware, combined with Wowza Streaming Engine's capabilities, is designed to optimize the distribution of transcoding and video processing, addressing common issues like inefficient GPU utilization and maxed-out CPUs for specific high-volume use cases. This approach underscores the growing need for specialized hardware and software integration to manage the escalating compute demands of modern streaming workflows, particularly those incorporating AI.
