Tweets around DevOps, Web development, if these Tech stacks excites you then follow me
Hold my Fruit beer, Lemme break this buzzword from the cloud computing space for uh guys ⚡
The easiest explanation ⤵️
1) The Ancient IT Infrastructure
Back to old time 🚀
There used to be two teams in the past; 1) The Development Team 2) The Operational Team
The Dev Team used to Develop applications and the Operational team used to Deploy and manage the applications after Deployment.
2) But, what was the problem in this ?
The problem is this
that the Development team has developed the application so the time taken by the Operational team to set up the environment was too much and the whole process was so much frustrating 😑

Even though there are a lot of alternatives available like Mesos from Apache, Docker swarm, but still Kubernetes is the leader🤞⚡
Why Companies are shifting towards Kubernetes ☸️🧑🏻🍳

How will you know which container should go where , what if a container fails?
