They promise that it lets us run any code anywhere at any scale. #Npm serverless tutorial code#OpenFaaS, as explained on their web site, “makes it simple to turn anything into a Serverless function that runs on Linux or Windows through Docker Swarm or Kubernetes”. To be clear, I personally don’t believe that you should go Serverless no matter what, but rather see it as a valid concept that might solve parts of your problems. #Npm serverless tutorial software#If you want to learn a bit more about the concepts and what Serverless architecture entails, I recommend watching “Serverless: the Future of Software Architecture” by Peter Sbarski. Serverless overall has relevant positive characteristics and should be part of our discussions around reliable architecture alternatives. This technique, for starters, helps to optimize costs but also requires awareness of cold start situations. A FaaS platform will not only scale out your code if it’s under heavy load but also take care of removing instances if the function has not been invoked much for a while. “Functions” in the context of FaaS are rather small units that generally should be stateless and can, as a result, easily be scaled horizontally. The code can be deployed without maintaining infrastructure and just by uploading functionality to the cloud, which takes care of executing and also scaling the function. The general idea behind FaaS is to offer a platform that can be used to execute code triggered by some event. Many more tools and platforms exist, which are also part of the landscape map shown above. There are also open-source alternatives, such as Apache OpenWhisk or Oracle’s Fn Project. Many vendors provide these platforms, with the most prominent ones being AWS Lambda, Google Cloud Functions, and Microsoft Azure Functions. One of the most essential Serverless offerings are so-called compute runtimes, also known as function as a service (FaaS) platforms. Monolith -> Microservices -> Serverless architecture Serverless architecture is said to be the next big thing and somewhat the advancement of microservices: The Serverless opportunities seem endless, and so does the landscape map published by the Cloud Native Computing Foundation (CNCF), which you can find here. The term “Serverless” describes the fact that we don’t have to care much about infrastructure setup, scaling, and maintenance and that we can focus on developing code which can easily be deployed into production. With Serverless Computing, we describe a cloud model in which server management and infrastructure decisions don’t have to be tackled by the developers, but are taken care of by the cloud providers themselves. Serverless and Function as a Service Serverless Computing Throughout this post, we want to learn about the concepts behind Serverless and Function as a Service (FaaS), and how we can deploy Serverless Kotlin functions to OpenFaaS. #Npm serverless tutorial free#As a result, you are free to choose any programming language as long as it can be packaged into a Docker image. You can run your Docker image on OpenFaaS, which runs and scales it for you. OpenFaaS is an open-source, community-owned project that you may use to run your functions and microservices on any public or private cloud. With this article, my goal is to demonstrate how Serverless Kotlin can look like by introducing you to one of the coolest Serverless platforms: OpenFaaS.
