When VPS is the better fit
A dedicated-compute VPS is quick to provision, simple to replace and well suited to pilots, smaller production environments and isolated components such as Greenlight. Verify that CPU resources are truly reserved.
When bare metal earns its place
Physical servers offer the most predictable access to CPU, memory and local storage. They fit sustained media loads, stronger single nodes and standardised cluster fleets.
Scaling changes the comparison
Several repeatable VPS nodes may offer easier incremental growth, while fewer powerful bare-metal nodes can simplify raw capacity. Availability requirements may favour more nodes regardless of their individual size.
Migration is part of the cost
Account for DNS, recordings, integrations, firewall rules and maintenance windows. The cheapest monthly price may not be cheapest if the platform has to move again immediately.
The operational reality
BigBlueButton capacity depends on how people use media. Hardware specifications help narrow the choice, but your own load test, monitoring and failure plan turn that choice into a production design.
