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.

Akka features and specs

• Scalability
  Akka is designed to handle high concurrency and provides excellent scalability by leveraging the actor model, enabling developers to build distributed systems that can efficiently scale up or out across multiple nodes.
• Resilience
  Akka promotes building systems that are resilient to failures, using features like supervision strategies and self-healing, to automatically recover from errors and maintain system stability and uptime.
• Concurrency
  By using the actor model, Akka facilitates easier handling of concurrency, allowing developers to work with asynchronous and non-blocking message-driven communication that reduces complexities associated with multithreaded programming.
• Flexibility
  Akka integrates with a broad ecosystem of tools and technologies and can be easily used with various JVM-based languages such as Scala and Java, providing flexibility in designing and implementing solutions.
• Event-driven Architecture
  Akka supports building reactive, event-driven applications, which are responsive, maintainable, and adaptable to changing demands and requirements.

Possible disadvantages of Akka

• Steep Learning Curve
  The actor model and the associated paradigms in Akka present a steep learning curve for developers who are accustomed to traditional object-oriented or procedural programming models.
• Debugging Complexity
  Debugging in an actor-based system can be more challenging compared to traditional systems, due to the asynchronous nature of message passing and lack of a global state.
• Overhead
  There can be additional overhead associated with context switching and message passing between actors, which might impact performance in scenarios with extremely high-frequency messaging.
• Integration Challenges
  Integrating Akka with existing systems or libraries that are not designed for an actor-based model can pose challenges, requiring developers to adapt or wrap existing codebases.
• Tooling and Ecosystem
  While the Akka ecosystem is growing, it still lacks the extensive tooling support found in more traditional frameworks, making certain tasks like monitoring and tracing more cumbersome.
