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.

reStructuredText features and specs

• Readability
  reStructuredText offers a clean, readable syntax that resembles plain text, making it easy for humans to read and write without requiring special software.
• Extensibility
  It permits extensions and custom directives, allowing users to create new functionalities and adaptations specific to their needs.
• Integration
  It is the default markup language for Python documentation and is naturally supported by Sphinx, which makes it suitable for generating detailed and attractive documentation.
• Semantic Richness
  reStructuredText supports comprehensive semantic markup structures, enabling detailed annotations and proper structuring of documents.

Possible disadvantages of reStructuredText

• Complexity
  Learning all of the features of reStructuredText can be complex for beginners due to its wide range of functionalities and strict syntax rules.
• Limited Adoption
  Compared to Markdown, reStructuredText has a smaller user base and community support, which can limit resources and examples available for new users.
• Tool Support
  While it is well-supported in Python environments, outside this ecosystem, there are fewer tools and editors that provide full support and previews for reStructuredText.
• Less Forgiving
  The syntax is more rigid and less forgiving of errors compared to some alternatives like Markdown, which means small mistakes can lead to rendering issues.
