What You’ll Learn

Before we dive in, make sure you have:

• An AWS account with appropriate permissions
• Basic knowledge of Terraform and Infrastructure as Code (IaC)
• Familiarity with Jitsi Meet

Step 1: Understanding Jitsi’s Scaling Requirements

Jitsi Meet is an open-source video conferencing solution that can handle a significant number of concurrent users. However, as your user base grows, you’ll need to scale your infrastructure to maintain performance. The key components to scale include:

• Jitsi Videobridge (JVB)
• Jicofo (Jitsi Conference Focus)
• Prosody XMPP server

Step 2: Setting Up Your AWS Environment

1. Log in to your AWS Management Console
2. Create a new VPC for your Jitsi infrastructure
3. Set up security groups and IAM roles

Step 3: Installing and Configuring Terraform

1. Download and install Terraform from the official website
2. Set up AWS credentials in your local environment
3. Initialize a new Terraform project directory

Step 4: Writing Terraform Scripts for Jitsi Scaling

Create a main.tf file with the following structure:

# Provider configuration
provider "aws" {
  region = "us-west-2"
}

# VPC and networking resources
resource "aws_vpc" "jitsi_vpc" {
  # VPC configuration
}

# EC2 instances for Jitsi components
resource "aws_instance" "jvb" {
  # JVB instance configuration
}

resource "aws_instance" "jicofo" {
  # Jicofo instance configuration
}

resource "aws_instance" "prosody" {
  # Prosody instance configuration
}

# Auto Scaling Group for JVB
resource "aws_autoscaling_group" "jvb_asg" {
  # Auto Scaling Group configuration
}

# Load Balancer
resource "aws_lb" "jitsi_lb" {
  # Load Balancer configuration
}

Step 5: Deploying Your Scaled Jitsi Infrastructure

• Run terraform init to initialize your Terraform working directory
• Execute terraform plan to preview the changes
• Apply the changes with terraform apply

Step 6: Managing and Monitoring Your Jitsi Infrastructure

• Set up CloudWatch alarms for key metrics
• Implement log aggregation using CloudWatch Logs
• Regularly review and optimize your infrastructure
