Developed by the European Project-COLA under grant agreement No 731574


Automated scaling on the level of application

MiCADOscale scales applications on both levels. The level of the virtual machine, as well as the level of the container.

Dashboard for monitoring

MiCADOscale offers an integrated, secured Dashboard with various monitoring options. The Dashboard can be used to track custom inquiries.

Multiple cloud support

MiCADOscale supports scalable applications on various cloud infrastructures like: EC2, OpenStack, CloudSigma & Cloudbroker

Secure distributed systems

Secure the different containers in your distributed systems via Zorp's proxy firewall.


MiCADOscale is a generic framework, capable to switch some of it's core-components. Instead of using Docker-Swarm, you could also modify MiCADOscale to utilise Kubernetes.

Highly customizable scaling policies

Scaling policies can be defined specifically for the requirements of your applications.

What is MiCADOscale?

The generic plugin framework MiCADOscale (Developed by the members of Project-COLA) supports the optimal and secure deployment of scalable cloud applications.

Almost every IaaS provider offers scalability and elasticity, but most existing applications will not make the most of these features automatically without drastically changing their source code. Current orchestration solutions usually reach not directly into the level of the application itself. For this reason, the scaling logic must be implemented deeply within the application.

MiCADOscale manages the orchestration at the application level by scaling VMs and their included Docker containers based on the resources currently required. MiCADOscale is provided through an Ansible playbook to reduce the configuration time.

Once the core environment has been installed and put into operation, every aspect of your future applications can be tracked with the MiCADOscale-Dashboard, and the logs of the MiCADOscale master node are monitored and logged.

Get MiCADOscale:

MiCADOscale is managed through GitHub.

MiCADOscale is designed for Debian-Linux machines. We recommend using Ubuntu 16.04 & up. To install the latest version of MiCADOscale, please use the detailed documentation.

How it works?:

By deploying MiCADOscale, the MiCADOscale-Masternode will be started (instantiated). This node can be deployed on a local or remote machine in the cloud. The Masternode contains all core components for scaling your application in production. It will organize and manage the deployment process of workers in your application cluster and also perform as the server for the MiCADOscale Dashboard.

Most of MiCADOscale's core-components are interchangable. This means, you could - for example - swap Docker-Swarm for Kubernetes to fit your specific usecase.

The package consists of:


Docker Swarm



Policy Keeper

Multicloud support:

MiCADOscale is able to operate on several target clouds. Currently supported infrastructures for MiCADOscale are:

  1. Amazon AWS EC2
  2. OpenStack
  3. CloudSigma
  4. CloudBroker Platform

Application description:
To deploy an application with MiCADOscale, you will need to specify a detailed description of your application for the MiCADOscale-Masternode. MiCADOscale utilises TOSCA-based description files called "ADT's" (Application Description Templates). These ADT's are split in 4 parts and will describe the the specification of the interconnected container's and the virtual machines, as well as the scaling logic for the application. ADT's are written in JSON-format, so you have to check their integrity carefully before using them.

How to create ADT's

If you want to learn to write your own ADT's to support your application, this video should give you a brief example in how to start the development. The video will teach you the basics of the TOSCA standart, as well as the structure of a valid ADT.

If you ran into any trouble during your ADT creation or adaptation, do not hesitate to contact us via the contact form. We will try to solve your issues together!

MiCADOscale in production:

Once an ADT is submitted to the MiCADO-Submitter within the MiCADOscale-Master node, it will automatically download the needed packages, configure the networking relations and initiate the minimum required Worker nodes for your application.

If Prometheus detects an alert based on your scaling logic, it will notify Swarm or Occopus to scale up the Containers/VMs to your specified limit. After the detected peak is over, another alert will be triggered to scale your application down to save costs.
