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.

  Pusher Beams is built to handle large volumes of notifications efficiently, making it a suitable choice for applications with a growing or large user base.
• Reliability
  The service uses robust infrastructure to ensure the delivery of notifications, even under heavy loads, which enhances the reliability of the communication.
• Advanced Features
  Beams offers advanced features such as user segmentation and detailed analytics, aiding in the creation of targeted notification campaigns and performance tracking.

Possible disadvantages of Pusher Beams

• Cost
  While Pusher Beams offers a free tier, the costs can increase significantly with scale, which may be a consideration for smaller projects or startups.
• Dependency
  Using a third-party service like Pusher Beams means additional dependency on their infrastructure and uptime, which could be a risk if the service experiences downtime.
• Limited Customization
  While the service offers many built-in features, there may be limitations when it comes to custom use cases or very specific requirements that fall outside the provided capabilities.
• Data Privacy
  Using any external service to handle user data introduces potential privacy concerns, particularly if the application involves sensitive information that needs stringent privacy controls.
• Notification Delivery Limits
  There can be limits on the number of push notifications that can be sent per month or per second, which might necessitate significant planning and optimization for high-traffic applications.
