Open-source messaging and streaming server 2.15.2 (Apache-2.0) on Ubuntu 24.04: publish/subscribe, request/reply and persistent streams, with a login required on every connection and WebSocket access over HTTPS.
Overview
This AMI runs a lightweight open-source messaging and streaming server on Ubuntu 24.04 LTS: publish/subscribe, request/reply and queue groups for connecting services, plus persistent streams and key-value stores for messages that must survive restarts. It is the unmodified open-source release 2.15.2, pinned and baked into the AMI, so first start does not depend on a registry and nothing is downloaded when it starts. Persistent data is kept on disk on the instance.
What Perimattic adds
Closed by default: out of the box this kind of server accepts every client without a login. Here a user name and a random 24-character password are generated on your server at first login, and every connection must present them, on the native client port and on the WebSocket listener alike. The password is stored in the configuration only as a bcrypt hash. Setup checks that the login connects, publishes, subscribes and uses persistent streams, and that clients with no credentials, a wrong password, a token and common default logins (admin/admin, guest/guest and others) are refused, before the site is published.
No open ports to the internet: the native client port and the monitoring port are published on the server's loopback interface only. Remote clients connect over WebSocket through Apache on HTTPS (port 443, with a free Let's Encrypt certificate requested for your domain with certbot) with the same login, or through an SSH tunnel to the client port; the exact commands are printed at the end of setup. The tests open real WebSocket connections through Apache, refuse anonymous and wrong-password ones, and publish, subscribe and use persistent streams over them. Only ports 22, 80 and 443 are open.
Durable and sized: persistent streams are stored on disk, capped at 4 GB on disk and 256 MB in memory; the tests create a stream, reboot the server and read the message back. Messages are limited to 1 MB and connections to 512. The server runs as an unprivileged user. Users can be added by editing the configuration and reloading, which the tests also exercise. Pinned and patched: the version is fixed, not 'latest', and Ubuntu 24.04 LTS is built through an automated EC2 Image Builder pipeline with security updates applied at build time.
Limits you should know
There is one login with full access; per-user permissions need configuration edits. The native client port is not opened to the network and has no TLS: use the WebSocket address or the SSH tunnel. Monitoring has no login and stays on the server only. This is a single server: clustering, leaf nodes, MQTT and the system account are not enabled. In our tests the server used about 10 to 25 MB of memory (about 550 MB for the whole host), so a t3.small is a comfortable size.
Licence and attribution

Getting Started Launch the AMI and open ports 22, 80 and 443 in the security group SSH in and answer the setup prompts (domain and admin email) Note the user name and password printed at the end of setup Connect a client over WebSocket to your domain on port 443, or through the SSH tunnel, and publish your first message
A domain name with an A record pointing at the instance is required, because the WebSocket address is served over HTTPS.
This AMI is built and supported by Perimattic.

Dimensions summary
You pay by the hour based on the EC2 instance type you run this managed messaging and streaming server on. Each dimension names a specific instance size, grouped into families such as compute-optimized (c-series), memory-optimized (r- and x-series), storage-optimized (d- and i-series), general-purpose (m- and t-series), and accelerated compute (g-, p-, inf-, and trn-series). Larger sizes within a family carry more vCPU and memory, so your hourly rate scales with the capacity you choose. Billing is usage-based, so you pay only for the hours each instance runs. No upfront commitment applies.
Top-of-mind questions for buyers
Each unit is one running EC2 instance of the named type, billed per hour it runs. The rate reflects that instance's vCPU and memory. Fully stopped instances do not accrue software charges, since billing meters running time only. Underlying AWS storage fees may still apply while stopped.
This is usage-based with no upfront commitment. You subscribe, launch an instance, and pay only for the hours it runs. You can change instance types or shut instances down at any time, and charges stop when the instance stops.
The service handles provisioning, security patching, version upgrades, daily backups, and monitoring for the messaging and streaming server. Instances run on dedicated infrastructure in your chosen region. A full data export is available on request, so you can move to self-hosting without negotiation.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.

Additional details
Usage instructions
-
Launch an Instance
From AWS Marketplace, click Continue to Subscribe and then Continue to Configuration to launch the AMI.
-
Choose the Recommended Instance Type
t3.small (2 GB of memory) is the recommended size: the server used about 10 to 25 MB in our tests and the whole host about 550 MB. Choose t3.medium or larger for many connections or large persistent streams.
-
Configure Security Group
Allow inbound traffic on the following ports:
- 22 (SSH) - terminal access for setup
- 80 (HTTP) - needed to validate your domain for the TLS certificate
- 443 (HTTPS) - access to Messaging and Streaming Server
-
Point a domain at the instance
Create a DNS A record (for example messaging.example.com) pointing to the instance's public IP before you log in.
-
Connect to the Instance
ssh -i <your-key.pem> ubuntu@<public-ip>
-
First-Login Setup
The first SSH login runs a guided setup:
- Prompts for your domain and admin email and checks the DNS A record
- Generates a random 24-character password on your server and writes only its bcrypt hash to the configuration
- Starts the server, then checks that clients with no credentials, a wrong password, a token and default logins are refused, that the generated login connects, publishes, subscribes and uses persistent streams, and that the client and monitoring ports answer on the loopback interface only
- Configures Apache as an HTTPS reverse proxy for the WebSocket listener and requests a Let's Encrypt certificate
- Prints the user name and password and the connection commands; they are also stored in /opt/app/access.txt (root only)
If a step fails, fix the problem shown and log in again: the setup resumes where it stopped.
-
Access Messaging and Streaming Server
Note the user name admin and the password printed at the end of setup (view them again with: sudo cat /opt/app/access.txt). The same file shows the WebSocket address (wss://<your-domain>) and the SSH tunnel command for the native client port, and how to add users.
-
Credentials
Generated on your server, never shared between customers. View them again with:
sudo cat /opt/app/access.txt
-
Manage the Services
cd /opt/app sudo docker compose ps sudo docker compose restart
Persistent data is in /opt/app/data (persistent streams: up to 4 GB on disk); back it up or take EBS snapshots before upgrades. The native client port and the monitoring port are on the server's loopback interface only: use the WebSocket address on port 443 or an SSH tunnel.
