Today we have Cloud based services, which has taken over completely the legacy server hosting paradigm. Today we believe in focussing on code, and factors of scalability and server management are being taken care of very effectively by cloud providers.
Keeping a dedicated server is completely under your IT team observation so you need competence to manage the server yourself. You may need to spend for the technical or professional assistance to help manage the server.
One of the most popular framework around us, sort of a buzz word among developer’s community, is The Serverless Framework.
To be precise, just like wireless internet has wires somewhere, serverless architectures still have servers somewhere. But calling it serverless means that as a developer you don’t have to think about those servers. You just focus on code.
The Serverless Framework is a free and open-source web framework written using Node.js. Serverless is the first framework that was originally developed for building applications exclusively on AWS Lambda, a serverless computing platform provided by Amazon as a part of the Amazon Web Services. Currently, applications developed with Serverless can be deployed to other function as a service providers, including Microsoft Azure with Azure Functions, IBM Bluemix with IBM Cloud Functions based on Apache OpenWhisk, Google Cloud using Google Cloud Functions, Oracle Cloud using Oracle Fn, Kubeless based on Kubernetes, Spotinst and Webtask by Auth0.
A Serverless app can simply be a couple of lambda functions to accomplish some tasks, or an entire back-end composed of hundreds of lambda functions. Serverless currently supports Node.js and Python runtimes, but very soon in future will also support Java for AWS Lambda.
Serverless Applications are the next step in cloud-native development, and they require automation. If you’re tying together multiple managed services and functions, you cannot rely on a checklist of manual steps. You should be able to recreate your entire application with a command, using Serverless Framework CLI. The Serverless Framework CLI is used to build and deploy your application to any and every cloud provider.
Have a look the Serverless’ blog, and you will also be enthralled to see where applications development and deployment practices are heading to.
