Matrix is a relatively new decentralized open-source communication protocol designed for real-time online communication. It supports one-to-one messaging and voice calls, as well as group chats and video conferencing. Matrix-compliant servers are built on a decentralized architecture, enabling users on different servers to seamlessly communicate with each other through a common protocol, similar to the way email works.

Added the new service and updated the existent service contents of Flexisip install services.

The system is deployed using Docker containers based on the current stable release. HTTPS (TLS) connections are terminated at an Nginx container functioning as a reverse proxy, and requests are forwarded to a backend Apache container. Application processing for Account Manager and Lime, which was previously performed in the Nginx container, has been unified into the Apache container.

Based on the official installation script, the main components that make up FusionPBX — Nginx, PostgreSQL, PHP, and FreeSWITCH — are separated and managed as individual Docker containers. Operating FusionPBX in a Dockerized environment offers the following advantages: 1) Each component can be built using the latest stable versions in any desired combination. 2) Migration to other host environments is straightforward, minimizing environment-specific dependencies. 3) Multiple instances (multi-tenant or multi-environment setups) can be deployed flexibly. 4) Let's Encrypt enables easy and automated management of TLS certificates. 5) Host-level security controls such as iptables and fail2ban can be configured and managed independently from the application layer.

Instructions on how to build the latest version 3.0 of the web conferencing and classroom system BigBlueButton using Docker containers.

BigBlueButton is an open-source web conferencing system developed primarily for online education. It offers a wide range of features tailored to remote teaching and seminars, making it a popular choice among schools, universities, and learning platforms around the world. BigBlueButton provides real-time audio and video communication, as well as interactive tools essential for virtual classrooms—such as presentation sharing, a multi-user whiteboard, screen sharing, public and private chat, and breakout rooms for group discussions. Additionally, it supports session recording, allowing students and participants to review lessons and meetings afterward. Integration with learning management systems (LMS) like Moodle is straightforward, enabling a seamless online learning environment. The following outlines the steps to deploy and manage BigBlueButton using Docker containers.

In addition to operating the latest version of the open-source video conferencing system Jitsi Meet using Docker containers, we are also exploring a transition to a rootless container and pod-based deployment using Podman. The traditional Docker Compose-based setup often requires root privileges, which poses security risks to the host system. Podman, on the other hand, is an OCI (Open Container Initiative)-compliant container runtime that enables production-level environments to be built and run by non-privileged users. By integrating each Jitsi Meet component—web, prosody, jicofo, and jvb—within a single Pod, internal communication can be confined to a local network, minimizing unnecessary external connections and optimizing both security and performance. This Podman-based deployment is intended as a foundation for future system architecture that includes Kubernetes integration and automated scaling.

To build a server for registering public keys required for the X3DH key exchange process between users (Identity Key, Signed PreKey, One-time PreKey) using Nginx, MariaDB, and PHP, user authentication by an account manager will be used for key registration and retrieval.

Summary of Installation Notes(Forum article) for BigBlueButton (BBB) Open Source Video Conferencing System (Online Classroom System) – Upgrade from v2.4 to v2.6

If you have registered with Microsoft's cloud service Azure, you will be provided with several services that can be used free of charge for 12 months according to purpose, but the most practical service, virtual machines, can be used separately for each OS on Linux and Windows.

This is an article about the procedure to operate BigBlueButton with Docker container. BigBlueButton is an open source online learning system that is established by sharing each participant's voice, video, text message, etc. on the browser.

WireGuard itself is not server software, but VPN (Virtual Private Network) software that establishes peer-to-peer connections between terminals.

Deploy a CentOS7 docker container including the Official Flexisip Server and LAMP Server including Account Manager Web Frontend. LAMP Server and Flexisip Server run independently each other.

Construct Jitsi which is an open source web conference system on Docker. The conference systems like Zoom and Webex are supplied as free service, althoug in these services, there are some restrictions of time, members and so on to use.
