Lambdaliths, or monolithic applications deployed using AWS Lambda, create a debate within the serverless community regarding their advantages and disadvantages. While they can simplify development and improve portability, they may lead to higher cold start times, reduced scalability, and a loss of fine-grained telemetry data compared to the function-per-endpoint approach. Ultimately, the choice between Lambdaliths and single-route functions depends on specific application needs and traffic patterns.
