Hello everyone! Welcome to my blog!

We have reached the final article in our series on the 12 factors for the development of modern applications, inspired by the books of legendary Martin Fowler. If you missed our previous articles, don’t worry! Check out the other factors we have already covered.

Today, we will explore the twelfth and final factor:

Admin Processes

The twelfth factor highlights the importance of managing application administration and maintenance processes as unique and independent tasks. These processes should be executed in the same environment as the application, using the same configurations and resources.

Why are Admin Processes Important?

Managing admin processes efficiently brings various benefits, such as:

  1. Agility: Executing admin tasks as unique and independent processes allows developers and administrators to perform maintenance and updates quickly and efficiently.
  2. Consistency: By running admin processes in the same environment as the application, you ensure they work consistently and reliably across all environments.
  3. Security: By using the same environment and configurations as the application, admin processes inherit the same security policies and restrictions.

How to Manage Admin Processes?

Here are some tips and best practices for managing admin processes efficiently:

  1. Run in the same environment: Ensure that admin processes are executed in the same environment as the application, using the same configurations and resources.
  2. Separate admin processes from the application: Keep admin processes separate from the application, running them as unique and independent tasks.
  3. Automate recurring tasks: Use automation tools to perform recurring admin tasks, such as backups and updates.
  4. Monitor and log activities: Monitor and log all admin activities, including information about who executed the task, when, and what actions were performed.

Examples and Tools

Here are some tools and technologies that can help manage admin processes efficiently:

  1. Rundeck: Rundeck is an open-source operations automation platform that allows you to execute and schedule admin tasks in development and production environments.
  2. Ansible: Ansible is an open-source infrastructure automation tool that enables you to perform admin tasks consistently and efficiently across multiple environments.
  3. Fabric: Fabric is a Python library that simplifies the execution of remote admin tasks, such as application updates and configuration management.
  4. Kubernetes Jobs: Kubernetes Jobs is a Kubernetes feature that allows you to run unique or batch tasks in the same environment as the application, ensuring consistency and resource control.


With this final article, we conclude our series on the 12 factors for the development of modern applications. We hope you have found valuable information and best practices to improve the quality and efficiency of your projects.
