FOSSMeet 2016

The objective is to give an intro into the various components that make up a web application, on how in most applications evolve from few pieces and to more and more pieces connected together.

Outline

HackerRank is hosted using a large number of FOSS and few non-FOSS pieces, while it started out as a simple Ruby on Rails/Apache2+PHP server and a simple MySQL database, we have as the application grew added more components, most of them are either FOSS components, or managed instances of FOSS components.

I will be going through the evolution of the various components added and removed to the stack, why they were added or removed. They will try to include

• When did we add in-memory databases.
• For what do we use message queues.
• How do you build a secure codechecker that can run a large number of languages.
• How we deal with scaling
• How we deal with deployment
• Why we moved to a few managed services.

P.S : This talk is unlikely to add to knowledge of any current full stack developer who has worked on production applications.

Requirements

Should know basics of

• Linux
• How networks and servers work
• How a web application, in some language Ruby, PHP or Python works.
