Deploying Aesel

Go Home

System Requirements

In order to run Aesel, you should have at least one server with a minimum of:

  • 8GB RAM Available
  • 8GB Hard Disk Space Available

Note that production systems will likely require significantly more resources.

In order to run Aesel on Docker, you should have at least:

  • Docker CE >17.03 or Docker EE >17.06
  • Docker Compose >1.12.0 for using Docker Compose scripts

Running Aesel natively is supported on the following platforms:

  • Ubuntu >16.04
  • Redhat/Centos >7

Note that the above recommendations are minimum requirements, and production deployments will likely require significantly more resources, especially when handling very high-volumes of traffic.


Aesel is built to be horizontally scalable, so it can also run across multiple servers.

Crazy Ivan, CLyman, and Mongo form separate clusters which each manage disparate scenes. Adrestia forms a Service Mesh on top of these clusters, allowing transparent, transactional access. Neo4j, Adrestia, and Kelona are all completely horizontally scalabale, with many instances able to run simultaneously.

Consul Agents should run on each server as well. Mongo and Neo4j can all be clustered to increased scalability for the underlying data stores.


Docker images are available for all system components, so Aesel can be deployed on any architecture that supports Docker (ie. Docker Swarm or Kubernetes).

Load Balancing

Adrestia serves as the gateway for both HTTP, and will automatically load balance between instances of CLyman/Crazy Ivan. An HTTP reverse proxy (such as NGINX) can be used to balance between instances of Adrestia for HTTP requests, if desired.

When a device registers to a scene, it is provided an instance of CLyman to send updates to. This means that the UDP streaming is inherently load balanced within each cluster.


Aesel has several layers of security:


Transactional Security utilizes TLS (HTTPS) for encryption.

The following commands can be used to generate a self-signed SSL cert, along with a client cert. This can be used to test the secured transactional setup.

openssl req -x509 -newkey rsa:4096 -keyout caKey.key -out caCert.pem -days 365

openssl genrsa -out clientKey.key 2048

openssl req -new -key clientKey.key -out clientCert.csr

openssl x509 -req -in clientCert.csr -CA caCert.pem -CAkey caKey.key -CAcreateserial -out MyClient1.crt -days 1024 -sha256

Aesel utilizes Auth0 for it’s front-end authentication flows. This provides a number of integrations, and I suggest referring to their latest documentation to obtain a better understanding of how this all functions.

Adrestia provides JWT authentication with Spring Security, so is capable of authenticating from User Databases, social log-ins, etc. To test out authentication, you can visit http://adrestia-address:8080/login, making sure to replace ‘adrestia-address’ with the address of your instance.

You can follow this guide to setup your Auth0 account to integrate with Adrestia correctly.


UDP Events utilize AES-256-cbc encryption, with the key, password, salt, and IV set in the application configuration. AES-256 bit keys can be generated with the below command:

openssl enc -aes-256-cbc -k secret -P -md sha1

Where ‘secret’ is a password for generating the key.

Keep in mind that AES encryption is symmetrical, meaning that the encryption keys must be distributed to the clients in order to encrypt traffic between them and Crazy Ivan. The key and salt are delivered to end user devices after a registration transaction, which is both authenticated and encrypted.


Secure configuration values should stored in Hashicorp Vault, with full encryption and authentication enabled. Connecting and authenticating to any service requires accessing at least one secure property in Vault, ensuring that any malicious entities must go through Vault to get into any system in the network.

This does mean that your Vault instance should be carefully guarded: it has all of the keys to the castle. However, it is a system designed specifically to guard these secrets, so when used properly it is one of the best safeguards available, along with a healthy dose of common-sense.
