THE CHALLENGES COME Life is not like a dream

CHALLENGE #01Many languages (NodeJS, Python, C++, C#, Ruby, Scala, GoLang, …)Many platforms/libraries (OpenCV2, OpenCV3, .NET, …)Many environments (Ubuntu, Debian, Windows, …)Many databases (MongoDB, PostgesSQL, Redis, MySQL, SQL Server, …)Many other things (Active MQ, Rapid MQ, Mosquito, Hadoop, Spark, …)

Get right tool for the right job

SOLUTION #01

MONOLITHIC VS MICRO-SERVICES

WHEN ARCHITECTS DESIGN

WHEN DEVELOPERS DEVELOP

WHEN TESTERS TEST

CHALLENGE #02

CHALLENGE #02 – THE MATRIX FROM HELL

SOLUTION #02

SOLUTION #02

CHALLENGE #03We have many micro-services for images/videos processing.Those services used GPU core (CUDA) to improve speed.The challenge is How to put those services on 01 GPU Server independently.

CHALLENGE #04 – WELCOME ON BOARDLegacyI told him: Get a new PC with Windows Install NodeJS Install MongoDB Install Redis Install VMWare with Debian VM Install PostgresSQL Install MySQL …Nextday: Get code from GIT Configure for each thing Run each thing

With DockerI told:Get a new PC with Windows Install Docker-ToolboxGet code from GITDocker-compose upAnd coffee time

CHALLENGE #05 – TESTING

CHALLENGE #06 – DEPLOYMENT

DEMO TIME

THE SAMPLE MULTI SERVICES WEB APPDockerCoinsMiner is the application for mining DockerCoins. We have 4 services: Random Number (RNG): web service generating random bytes. (Ruby + Sinatra) Hasher: web service computing hash (Python + Flask) Worker: background process using RNG and Hasher (Python) WebUI: web interface to watch progress (NodeJS + ExpressJS + Redis)

THE SAMPLE MULTI SERVICES WEB APPDockerCoinsMiner is the application for mining DockerCoins. How it works: Worker asks to RNG to give it random bytes Worker feeds those random bytes into hasher Each hash starting with 0 is a DockerCoin DockerCoins are stored in Redis Redis is also updated every second to track speed You can see the progress with the WebUI
