AWS Lambda VS Poll Everywhere

• 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

• 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.

• Real-time Engagement
  Poll Everywhere allows for instant feedback and interaction, making it easier to engage the audience in a live setting.
• Ease of Use
  The platform offers a user-friendly interface, making it simple to create and manage polls even for those who are not tech-savvy.
• Versatile Question Types
  Poll Everywhere supports multiple question formats, including multiple choice, open-ended, word cloud, and ranking, providing flexibility in how you gather responses.
• Integration Options
  The tool integrates with popular presentation software like PowerPoint, Google Slides, and Keynote, allowing seamless inclusion in presentations.
• Mobile Accessibility
  Participants can respond via their mobile devices, ensuring accessibility and higher participation rates.
• Data Analysis and Reporting
  Poll Everywhere provides options for exporting data and generating reports, aiding in post-event analysis.

Possible disadvantages

• Limited Free Plan
  The free version has constraints on the number of participants and features, making it less suitable for larger events or advanced needs.
• Learning Curve
  While the interface is generally user-friendly, some advanced features require time to learn and master.
• Internet Dependent
  Both the presenter and the participants need to have a stable internet connection, which might be a limitation in areas with poor connectivity.
• Cost
  Premium features and higher participant limits require a subscription, which could be costly for smaller organizations or individuals.
• Customization Limitations
  Some users might find the customization options for themes and templates somewhat limited compared to other competitor tools.
