YAML

YAML stands for YAML Ain't Markup Language. It is a very popular data serialization format for storing configuration data or exchanging data between people and computers. It is more human-readable and concise than XML or JSON. It has become a key technology for creating complex configurations in various modern technologies like automation, testing, containerization, cloud (AWS, Azure, or GCP) deployment, DevOps, etc.

Why Learn YAML?

Learning about YAML would be very beneficial for today's software engineers. Below is a list of some popular software tools and frameworks that extensively use the YAML data format.

• DevOps - CircleCI, Travis CI, Azure DevOps, Jenkins X

• Frameworks: Spring Boot,

• Automation: Chef Automate, Ansible

• Container: Docker, Kubernetes

• Documentation: Swagger,

• and many more...
