Ruby on Jets: Like Rails but serverless

Does it really make sense to map each controller method to a lambda? Wouldn’t it make more sense to have gateway route to a single function per controller and then do the method routing inside that function? You’re going to get <i>a lot</i> of lambda functions otherwise.

I used Ruby on Jets for a small project a while ago. It worked <i>really</i> well, however I got the impression that the project was somewhat stalled and maybe losing support. Has that changed?<p><i>edit</i> Yea the github activity is still pretty concerning. But Rails seems to be having a little bit of a renaissance so maybe it will pick up here also.

Wondering why this framework isn&#x27;t more talked about, especially amongst rails devs to take advantage of AWS Lambda.

I&#x27;ve been using Jets for a small project, and it&#x27;s mostly been great. Coming from a Rails background, it was a very quick way to get a bunch of stuff running without any ongoing costs or babysitting. The documentation is pretty good, though there has been a few times where I&#x27;ve gotten a little stuck and have had to dig through the source to figure it out. Overall, I&#x27;m grateful for its existence.<p>Ultimately though I don&#x27;t think I&#x27;d use it beyond a proof of concept or without some sort of clear idea for how it will sustain itself.<p><a href="https:&#x2F;&#x2F;github.com&#x2F;boltops-tools&#x2F;serverlessgems&#x2F;issues&#x2F;6">https:&#x2F;&#x2F;github.com&#x2F;boltops-tools&#x2F;serverlessgems&#x2F;issues&#x2F;6</a>

Has anyone investigated what latency is like? Looks amazing for a low cost deployment, but I’d guess there could be significant startup latency for each controller.

former CTO @ Arist (YC S20). We were able to get all the way through series A using Ruby on Jets and it continues to be a major driver behind Arist&#x27;s growth. Tung, the guy behind it, is simply fantastic.

It looks like Ruby on Jets makes you 100% dependent on 1 company: AWS&#x2F;Amazon; not an evolution I&#x27;d welcome.

maybe its just me but serverless seems ill suited for these heavy garbage collected languages. Since you&#x27;re just spinning up a process shutting it down once it does its job, you&#x27;re really wasting a lot of cpu cycles on building up the garbage collector. A lot of the overhead is fine when you&#x27;re using a persistent instance where you can &quot;warm the cache&quot; so to speak. nodejs would be the edge of what I consider good for serverless. go is probably ok if you turned off the GC and rust would be ideal.<p>Then again, I&#x27;ve managed to completely avoid serverless as I find it to be a pita when you want to do anything more complex than a trivial crud app.

I use Dokku on a powerful Hetzner server for my rails apps. Am I missing out on something? My stuff has not too many users &lt; 1000 and those are mainly from EU and US. How would you host this?

Another Rails on Lambda framework is Lamby: <a href="https:&#x2F;&#x2F;lamby.custominktech.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;lamby.custominktech.com&#x2F;</a>

I wonder if this would help Mastodon (the project, not the generic term) since I thought the recent Twitter flight caused them scaling woes, but I don&#x27;t know enough of the details to readily know if one lambda per route would help them or not

Am I the only one who is kinda irritated with how AWS has effectively created a piecemeal proprietary operating system and slowly started displacing good server ops? All while &quot;supporting&quot; open-source development.<p>I really don&#x27;t want to be an AWS engineer. I like being able to host my own tools when I want.<p>Sorry for the rant, serverless stuff in general is cool.<p>As a followup... I&#x27;m curious if anyone can recommend solid opensource serverless runtime projects with decent management interfaces (CLIs are nice)? It would be neat if projects like Ruby on Jets could become &quot;lambda-agnostic&quot; for lack of a better tagline, if they&#x27;re not already.

Ruby syntax with a focus on fine grained transforming functions. Isn’t that essentially exactly what Elixir&#x2F;Phoenix tries to provide, but without the Amazon lock-in or price tag?

&quot;Like Rails but <i>serverless</i>&quot;, I wonder what&#x27;s their definition of servers?<p>As far as I understand it relies on .. AWS servers!

We should have buried Ruby along with Flash a while ago. It is not part of the future anymore (thankfully).
