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.

Cloud Firestore features and specs

• Real-time Updates
  Cloud Firestore offers real-time data synchronization, which ensures that any changes to the database are immediately reflected across all connected clients.
• Scalability
  Firestore can handle massive amounts of data and traffic, scaling automatically as your app grows without requiring manual intervention.
• Ease of Use
  Firestore provides a simple and intuitive API, which is easy to use for developers, especially those already familiar with Firebase services.
• Offline Support
  Cloud Firestore allows your application to remain functional and retain data even when offline, synchronizing changes when the connection is restored.
• Security
  Firestore uses Firebase Authentication and security rules to protect data, which is crucial for ensuring that your data is safe and that only authorized users can access it.
• Flexible Data Model
  It allows you to store data in a flexible, hierarchical structure which can adapt to various use cases and data requirements.

Possible disadvantages of Cloud Firestore

• Pricing Complexity
  Firestore uses a pay-as-you-go pricing model based on operations and data storage, which can become expensive and complex to manage as application usage scales.
• Query Limitations
  While Firestore supports a range of queries, there are limitations compared to SQL-based databases, such as the lack of JOIN operations and complex queries.
• Data Hierarchy Constraints
  Though it offers flexibility, the JSON-like data structure may require a rethink of data architecture, especially for complex relational data models.
• Vendor Lock-in
  Using Cloud Firestore ties your application to Google's ecosystem, which can make it challenging to migrate to another platform or database in the future.
• Learning Curve
  Developers new to NoSQL or real-time databases might encounter a learning curve, as Firestore’s data modeling and querying concepts differ from traditional relational databases.
