Hop on the Serverless adventure

347 Aufrufe

Serverless is the new black - I can deploy my application to the cloud without ever worrying about infrastructure. We all remember the days when we had to spend hours and hours configuring and debugging web servers when all we wanted was to just code and test our app. Those days are long gone and it’s time for us to unlearn how to provision and manage infrastructure while focusing on building and scaling applications.

  14. 14. @simona_cotin–Martin Fowler “Serverless architectures refer to applications that significantly depend on third-party services (knows as Backend as a Service or "BaaS") or on custom code that's run in ephemeral containers (Function as a Service or "FaaS")”

  27. 27. @simona_cotin “Serverless computing has made its way into the enterprise because it simplifies deployment and allows developers to focus more on application features than on tasks such as provisioning VMs. Emerging uses for serverless technology include image processing, task management, workflows and notifications.”

  29. 29. @simona_cotin •Javascript has a rich ecosystem of libraries and tools •Enable FE developers to build scalable backends •Large use base - javascript is the English of languages Why Node.js?
  30. 30. @simona_cotin •Lightweight - helps reduce cold start •Commonly run in a distributed, horizontally scaled fashion •Scripting means no compilation required to start from a portal •Runs equally easy on most OS’s Why Node.js?
