What is Jitsi? A Complete Overview
Jitsi is a collection of free and open-source projects that enable secure video calls, chat, and screen sharing. This article provides an overview of Jitsi, its features, and practical considerations for deploying it on a Self-Managed VPS and Virtual Dedicated Server (VDS).
System Requirements
Before deploying, ensure your server meets the following hardware requirements to ensure smooth video and audio performance:
- Do not purchase a server that only meets the minimum requirements. The minimum specifications represent the software's bare survival threshold and do not account for operating system overhead or production workloads. Running with only 4 CPU cores, 4 GB RAM, 20 GB of disk space, and a 100 Mbps network connection can result in performance slowdowns, system freezes, or unexpected crashes during periods of high usage.
- For a stable deployment, we recommend using at least 4 dedicated CPU cores, 8 GB RAM, a 20 GB SSD, and a 1 Gbps network connection. Consider allocating additional disk space if you plan to store recordings, logs, or other application data.
| Resources | Minimum Requirements | Recommended |
|---|---|---|
| CPU | 4 CPU cores | 4 dedicated CPU cores |
| Memory (RAM) | 4 GB | 8 GB |
| Disk | 20 GB | 20 GB SSD |
| Network | 100 Mbps | 1 Gbps |
