#DevDiscuss How do you handle security on a serverless system? Do you simply trust the provider blindly? How does that affect audits?

serverless architecture seems to involve a surprising number of servers #DevDiscuss

architecture which is serverless. #devdiscuss jk I have no idea someone send help

#devdiscuss multi-region serverless still has challenges, specifically with API gateway which is region-specific.

As I understand: Servered: manage OS, scaling, servers, & app stack Serverless: deploy a bag of functions on scalable platform #DevDiscuss

Everybody's heard the term but nobody truly knows what it is 😬 #DevDiscuss

#devdiscuss Does this imply you need a trustworthy IaaS offering to offer serverless PaaS??

#DevDiscuss You write code that lives in the cloud but you don’t have to be concerned with the server it runs on.

Podcasts are usually a good place to go for newer ideas and products like serverless. https://t.co/lzEGMn8ssY #devdiscuss

So you don't either know? Phew #DevDiscuss

In reply to @ThePracticalDev

gumnos Apr 4 @ 9:11 PM EDT

So basically, it's like Erlang, spinning up a bunch of generic "servers" that can then run arbitrary functions via messages. #DevDiscuss

bendhalpern Apr 4 @ 9:11 PM EDT

To confuse things slightly, there is a serverless framework called Serverless https://t.co/oG54NqXlat #devdiscuss

lucus_patrick Apr 4 @ 9:14 PM EDT

the best I saw was to think of serverless as “Worth based development” from https://t.co/ssokQjNgPu #devdiscuss

In reply to @gumnos, @ThePracticalDev

On-premise: you can kick it as-needed CoLo: you can drive there to kick it Cloud: you call someone up to kick it Serverless: ? #DevDiscuss

"Serverless computing allows you to build/run applications and services without thinking about servers" #DevDiscuss https://t.co/OaEphW5QOK

In reply to @ThePracticalDev

bendhalpern Apr 4 @ 9:19 PM EDT

While also sort of buzzwordy, the phrase "Function as a Service" provides a better model for what's going on. #devdiscuss

chrismunns Apr 4 @ 9:20 PM EDT

btw, Senior Developer Advocate for Serverless from @awscloud, so lets do this ;) #DevDiscuss

In reply to @ThePracticalDev, @awscloud

gumnos Apr 4 @ 9:22 PM EDT

Points for honesty. Looking forward to your contributions to the discussion based on your experiences. #DevDiscuss

thanks! engaging ya'll is literally my job! #DevDiscuss #serverless

In reply to @gumnos, @ThePracticalDev, @awscloud

bendhalpern Apr 4 @ 9:24 PM EDT

I found this portion of Fowler's article helpful. Statelessness of serverless is key, that's where proper architecture comes in. #devdiscuss

kellyjandrews Apr 4 @ 9:25 PM EDT

Psst. There's a server. And infrastructure. And headaches. #DevDiscuss

gumnos Apr 4 @ 9:26 PM EDT

So it's basically functional programming at web-scale for deployment. #BuzzwordSurfeit? #DevDiscuss

In reply to @ThePracticalDev

kellyjandrews Apr 4 @ 9:27 PM EDT

A bag of functions sounds like a prank gift you send your ex. #devdiscuss

In reply to @gumnos, @ThePracticalDev

chrismunns Apr 4 @ 9:27 PM EDT

there's FaaS (functions as a service) and there's #serverless (complete abstraction of server management) and there's the (cont) #devdiscuss

DanCortes94 Apr 4 @ 9:27 PM EDT

#DevDiscuss serverless is when you have no one but yourself to blame for the buggy behavior and no hardware to kick

chrismunns Apr 4 @ 9:28 PM EDT

the intersection of the two which is things like AWS Lambda which is both FaaS and #serverless #DevDiscuss

if you have to ever think about capacity management, deal with high availability or pay for idle its not #Serverless #devdiscuss

DanCortes94 Apr 4 @ 9:31 PM EDT

#DevDiscuss when you have a web service being idle while waiting for requests and doing nothing more you have to start thinking serverless

chrismunns Apr 4 @ 9:32 PM EDT

yes, there's a handful of opensource FaaS projects out there that you run yourself or in Docker. requires infra mgmt #DevDiscuss

"How many thought leaders does it take to rack and stack a #serverless infrastructure" sounds like the right joke here? #DevDiscuss

DanCortes94 Apr 4 @ 9:33 PM EDT

#DevDiscuss we have found serverless great for dividing UI and basic DB interaction like inserting data or light queries

gumnos Apr 4 @ 9:34 PM EDT

What distinguishes them? I.e. (FaaS ∪ Serverless) - (FaaS ∩ Serverless) #DevDiscuss

In reply to @chrismunns

DanCortes94 Apr 4 @ 9:34 PM EDT

#DevDiscuss web services that just do some processing, data insertion, small processing

In reply to @ThePracticalDev

chrismunns Apr 4 @ 9:35 PM EDT

batch processing, streaming data, web APIs, backend services, chatbots, alexa skills, IT automation + more #DevDiscuss #serverless

In reply to @ThePracticalDev

chrismunns Apr 4 @ 9:36 PM EDT

can have on metal/self managed FaaS, can't do the same with #serverless. could have other non-FaaS #serverless like DBs #DevDiscuss

In reply to @gumnos

kellyjandrews Apr 4 @ 9:36 PM EDT

I'm a huge fan of the serverless concept. The difficulty I have today is, think about debugging microservices. Now functions. #devdiscuss

I think Newton is technically serverless https://t.co/S8fBbb9YkM #DevDiscuss

bendhalpern Apr 4 @ 9:37 PM EDT

Any stateless function within an app seems like a candidate for serverless if that would lead to a better workflow #DevDiscuss

@thepracticaldev @chrismunns How does one address the latency issues common in #serverless deployments? #DevDiscuss

lucus_patrick Apr 4 @ 9:37 PM EDT

useful for ephemeral eventing, triggering, messaging #devdiscuss (if mission critical, use something else like SNS)

In reply to @ThePracticalDev

gumnos Apr 4 @ 9:39 PM EDT

as long as you take latencies into consideration. something, something "leftpad as a service" something #NPMjokes #DevDiscuss

In reply to @bendhalpern

levante85 Apr 4 @ 9:40 PM EDT

any non long running function in a microservice architecture that would not be penalized by the startup cost... #DevDiscuss

In reply to @bendhalpern

kellyjandrews Apr 4 @ 9:40 PM EDT

and outages, fallbacks, data failure. #devdiscuss

In reply to @gumnos, @ThePracticalDev, @chrismunns

chrismunns Apr 4 @ 9:40 PM EDT

latency in what part of it? #DevDiscuss

In reply to @gumnos, @ThePracticalDev

bendhalpern Apr 4 @ 9:41 PM EDT

Oh yeah. Easier for async work or latency tolerant synchronous. #DevDiscuss

In reply to @gumnos

chrismunns Apr 4 @ 9:42 PM EDT

outages the same way you would any cloud tech, multi-region, app level failover. for data failure not sure what you mean there #DevDiscuss

In reply to @kellyjandrews, @gumnos, @ThePracticalDev

chrismunns Apr 4 @ 9:43 PM EDT

where would "here" be? reaction time to an HTTP based API function should be pretty much the same (caveat cold starts) #DevDiscuss

castroreniero Apr 4 @ 9:44 PM EDT

#devDiscuss in a bank infraestructure is safe to use serverless?

In reply to @ThePracticalDev

twobree Apr 4 @ 9:44 PM EDT

Forgot about #devdiscuss, but that's OK. Topic is serverless arch. I have zero clue what that means. Some of the ELI5s are still above me.

bendhalpern Apr 4 @ 9:45 PM EDT

How confident are you that you know what "serverless architecture" is? #DevDiscuss

cameronbrister Apr 4 @ 9:45 PM EDT

Wholeheartedly agree. #devdiscuss

bendhalpern Apr 4 @ 9:19 PM EDT

While also sort of buzzwordy, the phrase "Function as a Service" provides a better model for what's going on. #devdiscuss

chrismunns Apr 4 @ 9:46 PM EDT

if you are moving towards microservice architectures anyway this is just an evolution of that. still same service->service calls #DevDiscuss

In reply to @gumnos, @ThePracticalDev

chrismunns Apr 4 @ 9:47 PM EDT

take for example a Kinesis->Lambda->DDB application. Handoff not really different if it was EC2 #DevDiscuss

Ones I've tried so far - lightweight web API, Alexa skill backend #devdiscuss

I wonder what @TrumpDBA's thoughts are on #serverless #devdiscuss

chrismunns Apr 4 @ 9:48 PM EDT

the more votes in the first two categories the more work I need to do #DevDiscuss #Serverless

bendhalpern Apr 4 @ 9:45 PM EDT

How confident are you that you know what "serverless architecture" is? #DevDiscuss

kellyjandrews Apr 4 @ 9:49 PM EDT

general data loss. It feels very brittle, and hard to debug. Not just like any other app #devdiscuss

In reply to @chrismunns, @gumnos, @ThePracticalDev

chrismunns Apr 4 @ 9:50 PM EDT

Well things like AWS X-Ray will help here. but also comes down to how you do logging/metrics in your code as well #DevDiscuss

What if not 100% AWS? Is the play just to move everything to AWS then? #devdiscuss

In reply to @chrismunns, @gumnos, @ThePracticalDev

chrismunns Apr 4 @ 9:51 PM EDT

one positive of services like AWS Lambda is that logging comes built in. just console.log your ish and its captured #DevDiscuss

Seriously. Can we do serverless without AWS? It seems like I just use your architecture. #devdiscuss

In reply to @chrismunns, @gumnos, @ThePracticalDev

chrismunns Apr 4 @ 9:54 PM EDT

sure there's other vendors in the space. just not as far ahead yet and with their own pros/cons #DevDiscuss

sorry! DynamoDB #DevDiscuss

In reply to @gumnos, @ThePracticalDev

gumnos Apr 4 @ 9:55 PM EDT

It seems as though the application of functions across streams of data makes this sound like "webscale sed" to me 😉 #DevDiscuss

In reply to @chrismunns, @ThePracticalDev

kellyjandrews Apr 4 @ 9:56 PM EDT

one vendor lock in to another? Every challenge so far you answer with another service 🤔 #devdiscuss

In reply to @chrismunns, @gumnos, @ThePracticalDev

chrismunns Apr 4 @ 9:56 PM EDT

well there's something to be said about "fully managed webscale sed"! #DevDiscuss

#serverless is FAKE NEWS! It was built by the Amazon as a SCAM to overcharge with hidden fees! BAD DEAL!
In reply to @cameronbrister

kellyjandrews Apr 4 @ 9:57 PM EDT

I love moving business logic to the front end and reduce the server to small bits. #devdiscuss

In reply to @chrismunns, @gumnos, @ThePracticalDev

chrismunns Apr 4 @ 9:57 PM EDT

no such thing as vendor-less #serverless. against the definition of it. also every tech decision one makes implies a "lock-in" #DevDiscuss

In reply to @kellyjandrews, @gumnos, @ThePracticalDev

kellyjandrews Apr 4 @ 9:58 PM EDT

But it feels more like a pyramid scheme to rely solely on AWS r/n #devdiscuss

In reply to @chrismunns, @gumnos, @ThePracticalDev

chrismunns Apr 4 @ 9:59 PM EDT

OR an incredible way to build applications with a massive reduction in care and feeding without a lot of pain #DevDiscuss

In reply to @kellyjandrews, @gumnos, @ThePracticalDev

kellyjandrews Apr 4 @ 9:59 PM EDT

I get that there is always lock in but moving off the web of AWS would be a real challenge #devdiscuss
