Does Lambda save money?

I'm curious, does Lambda really save money? It seems like a popular choice for cloud computing, but I want to know if it's actually cost-effective. With all the fees and charges associated with cloud services, it's important to me that I'm making the right choice for my business. Can you explain how Lambda can help me save money, or are there any potential drawbacks I should be aware of? I'd appreciate any insight you can provide.
