Are you spending too much on Lambda?

Here are some ways to save money on your Lambda bill.


#serverless #awslambda
Lambda is usually very cost-effective, you only pay when they run (with ms billing) and they scale to zero.

But a combination of misconfiguration and a high throughput use case can give you a nasty surprise when you get your AWS bill, esp if you don't have billing alerts set up.
A few of my clients have experienced this type of problem before. For example, when a function that is invoked millions of times a day is allocated with way too much memory. Or when provisioned concurrency is enabled on a function with a lot of memory.

People willing to start up are often worried about the initial set-up costs and it is a valid reason to worry about.
But when you dig a bit deeper you realise that with the ecosystem today you can create and run a startup in the most frugal yet effective way possible. 🧵
I have highlighted tools and ways to run your startup for free. This is decent enough to handle about ~ 500K requests easily, but of course it's application dependent too. Please feel free to suggest any other awesome resources I might have missed. #startup
@discord Use discord for #communication, discord can be configured to work like slack. Best part, discord is completely free, while slack averagely charges $10/user/month.

Given all the excitement over Lambda's per-ms billing change today, some of you might be thinking how much money you can save by shaving 10ms off your function.

Fight that temptation 🧘‍♂️until you can prove the ROI on doing the optimization.

#serverless #aws #awslambda
The moral of this tweet is as relevant now as ever:

Assuming $50 (which is VERY conservative) per dev per hour, it would have taken them 40 months to break even on just having the meeting, before writing a single line of code!
With the per-ms billing, you're automatically saving on your Lambda cost already, by NOT having your invocation time rounded up to the next 100ms.

Unless you're invoking a function at such high frequency, those micro-optimizations won't be worth the eng time you have to invest.

I'm taking my Production-Ready Serverless workshop online! 🥳🖖 We're running a 4-week workshop that take you through building a production-ready #serverless app from testing, deployment, security right through to observability.… #aws #awslambda
The curriculum covers everything you need to know for building production-ready #serverless apps, and there's something for everyone, from novice to experienced #AWS and #AWSLambda users. And the content is up-to-date and relevant for 2020 and (hopefully) beyond. Image
Every week we release new video lectures and hands-on exercises on Monday. You can do them at your own pace and get help from us & other students on our Discord server. And on Friday, we'll do a live Q&A session to answer your most burning questions, not limited to the curriculum

Here's a timely reminder why you should use the lumigo-cli if you use AWS and Lambda. Reason #1 - it lets you powertune (i.e. find the best memory setting) functions with a single command #aws #awslambda #serverless

Reason #2 - analyze the cost of Lambda functions across ALL regions in one command

Reason #3 - analyze Lambda cold starts across ALL regions in one command

just some random thoughts regarding #serverless and #awslambda cold starts, what if there's a unikernel-based runtime for LLVM/webassembly (that other langs can compile down to) that runs directly on firecracker?
it'd probably be lightening fast to boot and run, I remember seeing Mirage (ocaml) and Xen (erlang) projects that boot up a "container", handles the webrequest and shut down in under 10ms, problem was they're language specific, so it's hard to get broad support across langs
but with LLVM and webassembly where mainstream languages can compile down to, maybe a unikernel for these compilation target languages would address that issue and make the whole endeavour feasible?
