Container technology.

funny

Hey, I just found this pithy definition on Google: Docker. A software platform used for building applications based on containers — small and lightweight execution environments.

It's a different way to package, contain, and organize code.

You can basically create applications where code is stored in different containers, and can set parameters to either have them be dependent on one another or non dependent. Really helpful to use in creating multiple applications that use snippets of code in similar ways. Docker is used a lot in DevOps environments

********Need Suggestions********
Hi Folks,

I'm actively looking for a job change in a profile completely different than what I'm doing currently.
My manager is sending me on-site and this will interrupt my interviews and preparation also.
And by that time if I receive any offer letter, I don't know what should I do?

Shall I reject the on site opportunity or go with it and reject the new offer?
