AWS Lambda VS GEX Horizon

• 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 GEX Streaming
  Live sub-second WebSocket stream of net gamma exposure for SPX, SPY, QQQ, and major US equities, updated with every options trade.
• Call Wall Detection
  Auto-identifies the strike with largest net call gamma — acting as major upside resistance from heavy dealer selling pressure.
• 0DTE Options Flow
  Intraday analytics for zero-days-to-expiration options, isolating 0DTE gamma exposure from all-expirations to reveal same-day dealer hedging impact on price action.
• Put Wall Detection
  Automatically identifies the strike with the largest net put gamma, acting as strong downside support due to market maker delta buying obligations.
• Live Gamma Levels Matrix
  Consolidated real-time view of key GEX levels — call wall, put wall, zero gamma flip, and major gamma concentrations — across all tracked underlyings in a single dashboard.
• Dealer Hedging Velocity Index
  Measures the speed and magnitude of market maker delta hedging activity, indicating how much buying or selling pressure dealers must execute per unit of price movement.
