The best features that Serverless offers include being without the server, which itself says we don't need to depend on the server maintenance, and so we don't need to worry about these server things.

Serverless has positively impacted my organization as it has been a good experience for the team overall because it is a new framework that we had to learn, and cost-wise, it helps because moving to Serverless means you do not have resources spinning all the time.

My advice to others looking into using Serverless is that you can use it if you want to save money, if you don't want to manage servers, if you only want to be charged for the amount of time you use, and if you want to run code and ad hoc tasks.

I can share specific metrics indicating Serverless's positive impact: I achieved 100% uptime, an impressive feat compared to traditional servers that often experience downtime during peak usage.

Improving Serverless is a difficult question because I am not deeply familiar with Serverless, so it is really difficult for me to judge.

The scalability of Serverless is limited; as you increase your code, it is not scalable, and we need to think out of the box to solve several problems.

Transitioning from servers to Serverless results in a price increase due to the additional maintenance and patches AWS provides, but if costs could be reduced, more customers would consider moving to Serverless architecture.
