YAML features and specs

• Human readability
  YAML is designed to be easy to read and write for humans, with a clean and simple syntax that avoids complexity, making it ideal for configuration files where human interaction is expected.
• Hierarchical data representation
  YAML’s support for nested and hierarchical data structures allows for clear representation of complex data relationships, making it suitable for expressing data trees and other structured data.
• Data interchange format
  Because it is a serialization language, YAML is versatile for both data interchange between programming languages and as configuration files, offering broad applications.
• Simplicity
  YAML’s syntax deliberately avoids the use of complex elements like semicolons, braces, and quotes, which reduces the likelihood of syntax errors and makes the language less intimidating for users.
• Support for various data types
  YAML supports a wide range of data types including strings, numbers, lists, and maps, which allows it to accurately represent data structures necessary for most applications.

Possible disadvantages of YAML

• Whitespace sensitivity
  YAML relies heavily on indentation for data structure definitions, which can lead to errors if the document's whitespace is not carefully managed.
• Lack of standard libraries
  Compared to JSON or XML, there are fewer robust YAML libraries available across various programming languages, potentially increasing the effort needed to implement YAML in certain applications.
• Not ideal for all data types
  YAML does not natively support certain data types such as binary data or date/time values, requiring workarounds or extensions, which can complicate use cases that handle such data.
• Less performant parsing
  YAML parsing is generally slower than JSON due to its complex syntax and flexible features, which can be a drawback in performance-critical applications.
• Security concerns
  YAML parsers can be vulnerable to certain security risks like arbitrary code execution or entity expansion attacks, requiring additional precautions during parsing and validation.

AWS Lambda features and specs

• Scalability
  AWS Lambda automatically scales your application by running your code in response to each trigger. This means no manual intervention is required to handle varying levels of traffic.
• Cost-effectiveness
  You only pay for the compute time you consume. Billing is metered in increments of 100 milliseconds and you are not charged when your code is not running.
• Reduced Operations Overhead
  AWS Lambda abstracts the infrastructure management layer, so there is no need to manage or provision servers. This allows you to focus more on writing code for your applications.
• Flexibility
  Supports multiple programming languages such as Python, Node.js, Ruby, Java, Go, and .NET, which allows you to use the language you are most comfortable with.
• Integration with Other AWS Services
  Seamlessly integrates with many other AWS services such as S3, DynamoDB, RDS, SNS, and more, making it versatile and highly functional.
• Automatic Scaling and Load Balancing
  Handles thousands of concurrent requests without managing the scaling yourself, making it suitable for applications requiring high availability and reliability.

Possible disadvantages of AWS Lambda

• Cold Start Latency
  The first request to a Lambda function after it has been idle for a certain period can take longer to execute. This is referred to as a 'cold start' and can impact performance.
• Resource Limits
  Lambda has defined limits, such as a maximum execution timeout of 15 minutes, memory allocation ranging from 128 MB to 10,240 MB, and temporary storage up to 512 MB.
• Vendor Lock-in
  Using AWS Lambda ties you into the AWS ecosystem, making it difficult to migrate to another cloud provider or an on-premises solution without significant modifications to your application.
• Complexity of Debugging
  Debugging and monitoring distributed, serverless applications can be more complex compared to traditional applications due to the lack of direct access to the underlying infrastructure.
• Cold Start Issues with VPC
  When Lambda functions are configured to access resources within a Virtual Private Cloud (VPC), the cold start latency can be exacerbated due to additional VPC networking overhead.
• Limited Execution Control
  AWS Lambda is designed for stateless, short-running tasks and may not be suitable for long-running processes or tasks requiring complex orchestration.
