Deploy a Serverless Application

[KPull]

Description

In Serverless (or rather, "Functions as a Service"), a developer simply uploads codes for a number of stateless business processes onto the cloud provider's infrastructure. The cloud provider will take care of all the necessary infrastructure setup to run your code. In fact, the developer is free to think only about their business logic rather than any concerns with regards to scaling up/down, deploying the app and so on. The developer will then be charged for the execution time of their functions.

We should try out AWS Lambda product: set up an AWS API Gateway trigger which executes a function on AWS Lambda. We should avoid using Java (although it is possible) since Java takes more time to execute (because it loads the JVM) and use either Node.JS or Python.

Outcome

• Get familiar with AWS Lambda
• Check out the Serverless Framework and see how it can help with the development of Serverless apps
• Deploy a function onto AWS Lambda and invoke it
• Make a reasonable assessment of this new technology

I played a bit with this idea at a couple of conferences I attended.
