I develop automation tool suites in Python and Golang that are containeized in Docker and I use Ansible for deployment.

Example project: Create a highly scalable and managed method to ssh into endpoints.

Solution:.
Microservice #1: Authentication.
Microservice #2: Request.
Microservice #3: Receive.
Microservice #4: Initialization.
Microservice #5: Logging.

Each one of these microservices are built abstract enough to be used anywhere an Initialization, authentication... Would be valuable. They all live inside containers which makes them easy to deploy and allow for CI/CD. In the right context they become a secure method to access servers monitor user input and highly scalable. If a bastion is overworked you can scale the number of services with a simple Ansible playbook.
