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.

Cortex Project features and specs

• Scalability
  Cortex is designed for high scalability, allowing it to handle extremely large volumes of metrics. It uses a distributed architecture that can scale horizontally by adding more nodes.
• High Availability
  Cortex supports replication and redundancy, which ensure high availability of metric data. This means that even if some components fail, Cortex can continue to operate without data loss.
• Multi-Tenancy
  The platform supports multi-tenancy, making it a good choice for organizations that need to manage and isolate metrics for different users or teams within the same infrastructure.
• Compatibility with Prometheus
  Cortex is fully compatible with Prometheus, using the same querying language and client libraries. This allows for easy integration and migration from a Prometheus setup.
• Long-Term Storage
  Unlike Prometheus, which is optimized for short-term storage, Cortex provides capabilities for long-term storage of metrics, useful for historical analysis and audits.

Possible disadvantages of Cortex Project

• Complexity
  The distributed nature and the multitude of components in Cortex can make it complex to set up, configure, and maintain, especially for smaller teams with limited resources.
• Resource Intensive
  Due to its architecture and capabilities, Cortex can be resource-intensive, requiring significant computational and storage infrastructure to operate efficiently.
• Operational Overhead
  The operation of Cortex can introduce additional overhead, as it might require teams to manage additional services and configurations beyond what is needed for a standard Prometheus setup.
• Steeper Learning Curve
  Users may face a steeper learning curve due to the distributed nature of the system and its configuration requirements, which can be challenging for newcomers.
