Ribon is a simulation service for deriving the cost-optimized configuration of AWS EC2 instances using RI (Reserved Instance).

Currently, AWS provides five kinds of RI pricing policies, which is cost-efficient at most 77% compared with on-demand instance. If you input your expected usage of AWS EC2 instances, you can get the cost-optimized RI configuration.

The project is written in R. Particularly, Shiny package is used for service dashboard and lpSolveAPI library is used for solving linear problem.

Installation

To run the service, R should be installed (http://www.r-project.org/). Then, install four R packages:

install.packages("lpSolveAPI")
install.packages("ggplot2")
install.packages("reshape")
install.packages("shiny")
library(shiny)

All your preparations are done. Run the service:

runApp("shiny")

You can specify your IP address and port number (e.g., IP: 1.2.3.4, Port: 8788):

runApp("shiny", port = 8788, host = "1.2.3.4")

You can see your service on http://1.2.3.4:8788.

Usage

Choose the file "data/input-test.csv" as the expected usage of instances, then you can check the input and ouput information on the right panels.
