Origins of term "Serverless"Jun 21, 2017
Serverless is new trend in software development. It’s confusing many developers around the world, let’s try to find origins of term “Serverless”. First time Ken Fromm in 2012 use this term in his article. (Ken added a bit of clarification in the comments to give credit where credit is due.)
1. First time I saw the term was in a blog post by Diego Basch on using Indextank and Iron to create a serverless search engine.— KenFromm.eth (@frommww) July 30, 2017
2. We (Iron) reposted it and used the term a few more times in blogs prior to my October 2012 article.— KenFromm.eth (@frommww) July 30, 2017
3. Not sure who wrote those posts that used the term in the title - Chad, Travis, or me - as we were sharing a Blogger accounts.— KenFromm.eth (@frommww) July 30, 2017
4. But the post I wrote for ReadWrite was the first one that defined the term and called it out as a specific movement.— KenFromm.eth (@frommww) July 30, 2017
Later Badri Janakiraman mentioned that he also heard about usage of the term in 2012 in context of Continuous Integration. For example Travis CI, where you can delegate Continuous Integration and testing of your project to Travis CI.
Later in 2014 Amazon Web Services announced a new service Lambda, a stateless event-driven compute service for dynamic applications that doesn’t require provisioning of any compute infrastructure. As a result in 2015 we see lot’s usage of term serverless.
In October 2015 there was a talk at Amazon’s re:Invent conference titled “The Serverless Company using AWS Lambda”, referring to PlayOn! Sports, where we can see real production usage of AWS Lambda and Serverless architecture. Let’s try to define term “Serverless”. Besides another trends in software development, there is no one definition of this term.
Serverless is delegating hardware or infrastructure to third parties or vendors.
Serverless describes applications that depend on services ‘in the cloud’
to manage server-side logic and state. For example we have ‘rich client’
and we want to use the vast ecosystem of cloud accessible databases (like Parse, Firebase), authentication services (Auth0, AWS Cognito), etc. These types of services have been previously described as ‘(Mobile) Backend as a Service’, and I’ll be using ‘BaaS’ as a shorthand in the rest of this article.
Wikipidea said, that Serverless is applications where some amount of server-side logic is still written by the application developer but unlike traditional architectures is run in stateless compute containers that are event-triggered, ephemeral (may only last for one invocation), and fully managed by a 3rd party. (Thanks to ThoughtWorks for their definition in their most recent Tech Radar.)
One way to think of this is ‘Functions as a service / FaaS’ . AWS Lambda is one of the most popular implementations of FaaS at present, but there are others. I’ll be using ‘FaaS’ as a shorthand for this meaning of Serverless throughout the rest of this article. from https://martinfowler.com/articles/serverless.html
