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.

React Native features and specs

• Cross-platform development
  React Native allows developers to write code once and use it to build applications for both iOS and Android platforms, significantly reducing development time and effort.
• Performance
  React Native uses native components under the hood, providing better performance compared to hybrid technologies like Cordova or Ionic.
• Community support
  React Native has a large and active community, which means plenty of libraries, tools, and support are available to help developers solve problems and add features.
• Hot reloading
  React Native supports hot reloading, enabling developers to see the results of the latest change instantly without losing the application's state.
• Reusable components
  Developers can use React Native's component-based architecture to create reusable UI components, making code more modular and easier to maintain.
• Strong backing
  Backed by Facebook, React Native benefits from continuous development, regular updates, and a high level of reliability and stability.

Possible disadvantages of React Native

• Complexity for advanced features
  Implementing complex features and achieving deep integrations with native APIs may require more effort and a good understanding of native programming.
• Performance limitations
  While React Native performs well for most use cases, it may still fall short in performance-intensive applications compared to fully native solutions.
• Limited third-party libraries
  Some third-party libraries might not be available for React Native, or they may lack features compared to their native counterparts.
• Platform-specific code
  Despite being cross-platform, certain features might still require platform-specific code, increasing the complexity when developing for both iOS and Android.
• Potential for outdated documentation
  As React Native evolves quickly, some documentation or tutorials might become outdated, leading to confusion and extra effort to find up-to-date information.
• Size of the application
  React Native applications tend to have larger file sizes compared to their native counterparts due to the inclusion of the JavaScript runtime and other dependencies.
