I have used AWS Lambda with Quarkus + Java, and struggled with cold start time however Lambda is still cost effective. so wanted to understand which one will be suitable as alternative to lambda services.

The main question here is your request rate. - If it's usually very high, then in most cases you shouldn't run into cold starts - and for the rare gaps, you can send a steady stream of "blank" requests that will keep the lambda's alive. - You can also consider pushing all your incoming requests to an SQS, and then triggering lambdas based on the sqs capacity - this way you'll be able to provide a constant level of service even with the cold starts

AWS Lambda

Have you used Provisioned Concurrency for your Lambdas? They can make a big difference, especially for Java.
