What the heck does "serverless" mean?
-
The "centralized versus distributed" debate is an ongoing source of techno-marketing hype. Mainframes gave way to workstations gave way to servers gave way to desktops gave way to the cloud.

The fox knows many things, but the hedgehog knows one big thing.Real talk. There's a time and place for both concepts IMO. Anytime peeps talk about a blanket one way for all things, is usually when it's fluff.

Here's what it actually means -- it means having someone else manage your servers where your stuff runs... From the book, Serverless as a Game Changer: How to Get the Most Out of the Cloud[^]
Quote:
Serverless Means Not Our Uptime One of the simplest definitions of Serverless, and the principal way I think about fully Serverless applications, is that the responsibility for keeping applications running is not the responsibility of the organization that developed the applications.
Yes, that's marketing -- not really technology!
Technically you can use lambda functions and be "serverless". But there's no server in the traditional sense at all. I didn't read the link mind you, but if they're suggesting it's just a server on the cloud executing code then that's not accurate.

Serverless computing - Wikipedia[^]:
Serverless computing is a cloud computing execution model in which the cloud provider allocates machine resources on demand, taking care of the servers on behalf of their customers. "Serverless" is a misnomer in the sense that servers are still used by cloud service providers to execute code for developers.
So basically, it's marketing BS. :)

It seems to be all the rage in web circles. I'm picturing an app that runs entirely in a browser and connects via web based APIs to do its back end processing, but that's my wild guess. How close am I? I've never gotten a clear answer out of google.

It means: someone else's server.

It doesn't run in the browser. Distributed model Client - API Server - Other services (database, etc) Hardware model for the above Client PC - Business PC - Services PC Serverless Client PC - Containerized App - Services PC --------------------------------- For the standard model if your business gets busy you must increase the number of Business PC instances using some method (manual or dynamic modeled by you). Note that you can do dynamic sizing at least in AWS. For serverless (ones I have seen) the midlevel is expanded automatically on demand without any need for you to determine that (basically - naturally there are management tools.) --------------------------------- There is more overhead with starting up a new Cloud PC than with a serverless container. Myself I would not trust it cost less except for immediate surge handling. Dynamic sizing as long as there is no immediate demand would probably cost less but one must then manage the dynamic modeling which is not very easy. --------------------------------- Serveless has the problem that it is stateless. So for example if you want to cache database results you would then need yet another Services PC to do that. Additionally surges might grow so big that it overwhelms the Services level. But that can happen with the Business level also without serverless. It cannot be used for everything that you might normally put into the Business level. There are limits (at least in AWS). Again some of that might be reflected in real business needs to do it that way but could also just be poor design (but refactoring is often not an option.)

It's funny that you mention "what is serverless" because I started reading the book below a few days ago. Read the 1st 3 chapters and i'm still not exactly sure. :laugh: You need to read this entire book, Serverless as a Game Changer: How to Get the Most Out of the Cloud[^] then you still won't know what it is. :rolleyes:

I'm not sure anyone knows. Its meaning probably depends on who you ask. lol For me it means something like Azure Function apps, which are microservices/functions that execute on a server somewhere in Azure. You don't have to worry about the server, its setup or maintenance. They aren't full apps, just single-purpose functions that can receive or pass data or objects to other functions if needed. Your only concern is the code.

The first paragraph in the book Azure Serverless Succinctly[^] by CP's very own Sander Rossel gives a good definition:
Quote:
Serverless computing is a cloud service where the cloud provider dynamically allocates infrastructure to run your code.

- Calvin (Bill Watterson, Calvin & Hobbes)That kind of makes sense to me except my little VPS does the same thing, and I don't understand the difference. Someone else explained it (I forget who now) as basically you're using someone else's server. That makes sense to me, although serverless != someone else's server, I at least understand it from a I guess a marketing? perspective even if it's a bit of a stretch.

This is no way related to me. Brainless maybe, but I'll have my applications with a server, thank you. :)

There are micro-services ... so there must also be micro-servers out there.

It is a way to simplify your deployment. The trade-off is it might cost you more money or save you some money depending on the traffic. It should always help with uptime/server-overload. If you are supporting traffic that sees incredible spikes, then this could auto-scale to help support the load. (Think Black Friday/Cyber Monday for retailers) If you have moderate, steady traffic, then it might not be worth it.
