CONTAINER AND MICROSERVICES: A ❤ STORY

WHAT ABOUT THIS

❤ STORY ?

💼 MY FIRST WORK DAY

MICROSERVICE’S PROS

▸ Relatively small

▸ Improve fault isolation

▸ Develop & deploy independently

▸ Improves tuning & scaling

🏃 MY SECOND WORK DAY

IT WAS NOT SO GOOD

▸ Additional complexity of a distributed system

▸ Testing is more complex

▸ Internal process for communication purpose

▸ A bad APIs design it’s very dangerous

▸ Development environment it’s hard to setup

MICROSERVICE’S CONS

Development environment it’s

hard to setup 😤

▸ Thanks to microservices, I found a way to use and understand containers

▸ Life is too short for waste your time
