An easily scalable solution with a variety of use cases and valuable event-based triggers
Pros and Cons
- "The most valuable features are event-based triggers. They're really good for a reactive style when you want things to happen as soon as something else happens."
- "With a highly variable load, our idle cost is pretty much zero, and we haven't had any scale barriers, so we've scaled smoothly."
- "There's room for improvement in the solution's warm start, which refers to the minimum time it takes to start up a Lambda function if you haven't been running it."
- "There's room for improvement in the solution's warm start, which refers to the minimum time it takes to start up a Lambda function if you haven't been running it."
What is our primary use case?
There's a lot of use cases. The solution is used for immediate processing, so it's used everywhere. When data comes in, you process a Lambda function to tag it and categorize it. I've used Lambda functions to process inbound videos to make them smaller. I've used a Lambda function as a serverless backend for a customer-facing app, so I didn't have servers running.
How has it helped my organization?
With a highly variable load, our idle cost is pretty much zero, and we haven't had any scale barriers, so we've scaled smoothly.
What is most valuable?
I think the most valuable features are event-based triggers. Basically, a Lambda function doesn't get called because you say, "I'm going to call it." It gets called because something happens: a file arrives, a message arrives, or a database gets written. It's really good for a reactive style when you want things to happen as soon as something else happens. That's the best pattern.
What needs improvement?
There's room for improvement in the solution's warm start, which refers to the minimum time it takes to start up a Lambda function if you haven't been running it.
For how long have I used the solution?
I have been using Lambda since 2014, so about eight years.
What do I think about the stability of the solution?
This is a stable solution.
What do I think about the scalability of the solution?
This solution is scalable. We have hundreds of thousands of users, so everything in Lambda gets used a little bit at a time in different parts of the process. We have plans to increase our usage in the future.
How are customer service and support?
I would rate the technical support as a ten out of ten. You are able to pick a language, pick an environment, and deploy it.
How would you rate customer service and support?
Positive
How was the initial setup?
It is pretty straightforward to set up this solution.
What was our ROI?
We've run some scenarios. For example, say you have three million requests per month, and 120 milliseconds each time someone requests. The total cost ends up being $2.73 a month, which is very cheap for what you get.
What's my experience with pricing, setup cost, and licensing?
There's two charges for this solution. There's the charge for how many times you call a Lambda function, which is 20 cents for every million function calls. Then there's also the size and amount of time that the Lambda function runs, which is measured as 0.0000166667 dollars. It's a fraction of a penny for every gigabyte second. A gigabyte, if you ran it for like a million seconds, would cost one dollar. It computes by the cycle, and it's very cheap.
What other advice do I have?
My advice is to think about the architecture first and don’t just throw your code into Lambda. Think about how your application is designed because using serverless is different.
I would rate this solution as a ten out of ten. It's a very critical service.
Which deployment model are you using for this solution?
