Introduction of YAML

YAML is a popular data serialization language used for configuration files, application states, and messages between applications. It's important because it's readable, versatile, and can handle various data serialization tasks. Here are some of the reasons why YAML is important: 

Readability

• YAML's indentation-based structure makes it easier to read, especially for complex configurations. It's also easier to read than XML because it doesn't rely on formatting symbols.

Versatility

• YAML can handle various data serialization tasks because it supports multiple data types and programming languages. For example, YAML supports data types like integers and floats, while JSON doesn't. 

Human-readable format

• YAML is a key player in DevOps because it serves as a human-readable format for configuration files. This enables teams to define and manage infrastructure settings and application configurations.

Clear syntax

• YAML's clear syntax simplifies the process of automation and orchestration in DevOps. 

YAML is a set of key-value pairs written like key: value. The values in a YAML file can be ints, floats, booleans, strings, or more complex types like maps and arrays.
