> It is being sold to businesses, that they don't have to manage a server. Do you mean a... computer? Server is a software term. It is a process that listens for network requests. At least since CGI went out of fashion, embedding a server right in your application has been the style. Serverless sees a return to the application being less a server, pushing the networking bits somewhere else. Modern solutions may not use CGI specifically, but the idea is the same. If you did mistakenly type "server" when you really meant "computer", PaaS offerings already removed the need for businesses to manage computers long before serverless came around. "Serverless" appeared specifically in reference to the CGI-style execution model, it being the literal description of what it is.

> Do you mean a... computer? Server is a software term. It is a process that listens for network requests. Between this and the guy arguing that UNIX doesn't have "folders" I can see that these kinds of threads bring out the most insane possible lines of rhetoric. Are you sincerely telling me right now you've never seen the term "server" used to refer to computers that run servers? Jesus Christ. Pedantry isn't a contest, and I'm not trying to win it. I'm not sitting here saying that "Serverless is not a marketing term for CGI" to pull some epic "well, actually..." I'm saying it because God damnit, it's true. Serverless was a term invented specifically by providers of computers-that-aren't-yours to give people options to not need to manage the computers-that-aren't-yours. They actually use this term serverless for many things, again including databases, where you don't even write an application or a server in the first place; we're just using "serverless" as a synonym for "serverless function", which I am fine to do, but pointing that out is important for more than just pedantry reasons because it helps extinguish the idea that "serverless" was ever meant to have anything to do with application design. It isn't and doesn't. Serverless is not a marketing term for CGI. Not even in a relaxed way, it's just not. The selling point of Serverless functions is "you give us your request handler and we'll handle running it and scaling it up". This has nothing to do with the rise of embedding a server into your application.

  > Serverless was a term invented specifically by providers of computers-that-aren't-yours to give people options to not need to manage the computers-that-aren't-yours. No. "Cloud" was the term invented for that, inherited from networking diagrams where it was common to represent the bits you don't manage as cloud figures. Usage of "Serverless" emerged from AWS Lamba, which was designed to have an execution model much like CGI. "Severless" refers to your application being less a server. Lamba may not use CGI specifically, but the general idea is very much the same.

    Okay. Let's ask Amazon since they invented the term: > Serverless computing is an application development model where you can build and deploy applications on third-party managed server infrastructure. All applications require servers to run. But in the serverless model, a cloud provider manages the routine work; they provision, scale, and maintain the underlying infrastructure. The cloud provider handles several tasks, such as operating system management, security patches, file system and capacity management, load balancing, monitoring, and logging. As a result, your developers can focus on application design and still receive the benefits of cost-effective, efficient, and massively scalable server infrastructure. Right. And that makes sense. Because again, what we're talking about when we're talking about AWS Lambda is serverless functions. But AWS also uses the term for other things that are "serverless", again, like Aurora Serverless. Aurora Serverless is basically the same idea: the infrastructure is abstracted, except for a database. This effectively means the database can transparently scale from 0 to whatever the maximum instance sizes Amazon supports without a human managing database instances. That's also the same idea for serverless functions. It's not about whether your application has a "server" in it.

      > Serverless computing is an application development model Exactly. And how that development model differs from the traditional approach is that you don't have to implement a server. Deployment isn't a development model. The development is necessarily done by the time you get there. > But AWS also uses the term for other things The terms has expended to be used for all kinds of different things, sure. There is probably a toaster out there somewhere solid as being "Serverless" nowadays. If we really want to get into the thick of it, "serverless" seems to go back much further, used to refer to certain P2P systems. But we know from context that isn't what we're talking about. Given the context, it is clear we are talking about "serverless" as it emerged out of Lamba, referring to systems that were CGI-esq in nature.
