Faq
Is AWS Lambda free?
Yes - free tier available, paid beyond free limits.
Does it support multiple languages?
Yes - Node.js, Python, Java, Go, Ruby, .NET, and custom runtimes.
Can Lambda run globally?
No - functions run in selected AWS regions.
Do Lambdas scale automatically?
Yes - AWS manages scaling based on incoming requests.
