Most streaming operations start on a VPS and stay there. A minority - high-output creators, media companies, multi-channel operations - eventually outgrow the VPS model. Here is how to know which camp you are in.
VPS Limitations
Shared CPU: VPS plans share physical CPU resources between multiple virtual machines. Under load, CPU performance varies. For streaming, variability means occasional dropped frames during CPU contention.
RAM ceiling: VPS plans cap RAM, typically at 4 - 16 GB depending on plan tier. Multi-stream + transcoding + FFmpeg processing + operating overhead compounds quickly.
Network contention: Shared uplinks mean bandwidth is not guaranteed. "1 Gbps" on a VPS means burstable, not dedicated.
When VPS Works Fine
For the vast majority of creators:
- Single stream (1 platform), 1080p60, no transcoding: 2 vCores, 2 GB RAM VPS is sufficient
- Multi-platform relay (3 destinations), 1080p60: 4 vCores, 4 GB RAM VPS is sufficient
- 24/7 lo-fi stream running ffmpeg: 2 vCores, 2 GB RAM
The VPS model is adequate for these workloads at a fraction of dedicated server cost.
When to Consider Dedicated
- Multi-channel operation (3+ simultaneous 1080p streams to different platforms)
- On-VPS transcoding for multiple quality tiers (360p, 720p, 1080p from the same source)
- Game server + streaming on the same machine
- Consistent sub-15ms latency requirements for live professional broadcast
A dedicated server provides exclusive CPU, guaranteed RAM, and a dedicated network uplink - your streaming competes with nothing.
The Upgrade Decision
Calculate your current VPS average CPU utilisation. If it exceeds:
- < 60%: Stay on VPS, you have headroom
- 60 - 80%: Monitor; consider upgrading before peak events
- > 80%: Upgrade now; you will have dropped frame events on heavy streaming days
