CONS

Security and stability of AWS Lambda need improvement, including better execution time and reduced cold-start delays.
AWS Lambda's pricing is considered high, making it less competitive compared to alternatives.
There are limitations in programming language support, including insufficient options for Python.
Integration with other providers like Cohesity and Druva and service limitations for long-running or specific processes require enhancement.
AWS Lambda's file system-sharing capabilities and memory limitations can hinder larger-scale implementations.

Automatic scaling is a valuable feature—when the number of requests increases, the system automatically scales up to the target we have set and scales down once the requests are resolved.

AWS Lambda needs to improve cold start time. Some AWS Lambda functions require a cold start, and if you need AWS Lambda to provide quick responses, you need some of the AWS Lambdas to be always on, which is risky.

I would rate their technical support as a seven out of ten. Overall, it is good, but there is some room for improvement when it comes to response time and overall competence.

While AWS Lambda covers scalability, reliability, and integration needs, I would like improved documentation for Lambda extensions and VPC configuration.

Regarding layers, you need to manually zip and install them. This step needs practice, and you might need to do it three to four times to get a hang of it.

AWS Lambda's limited execution uptime of fifteen minutes and cold start latency for some use cases are areas that could be improved, especially for event-driven applications, backend services for mobile and web applications, and real-time data processing.
Khaled Saidi - PeerSpot reviewer

AWS Lambda has a maximum execution timeout of 15 minutes, which is unsuitable for long-running tasks.

Sometimes AWS Lambda seems expensive, rating around five out of ten for pricing.

The runtime could be improved. There are certain use cases where I need a Lambda function to run longer.

I would say an increase in the current limits would be quite beneficial.
