DevOps Concepts & Benefits Explained | CBT Nuggets

In this video, CBT Nuggets trainer Shawn Powers explains DevOps. Sometimes the conversation of DevOps can immediately jump to processes and tools, but Shawn focuses on the concepts and benefits of DevOps. Learn just what DevOps is and whether you should consider it.

Whether in job interviews, conferences, board meetings or planning meetings, DevOps is coming up more and more.

The best way to understand DevOps is to start at its core principle: trust. DevOps is meant to merge two different disciplines together, and to do that effectively there must be good communication and trust.

On one side, developers. The code they’re responsible for creating must be compiled, uploaded, sent to clients, etc. In the world of DevOps, the developer can do things that they traditionally wouldn’t have because normally there’s an arbitrary wall that separates developers from operations.

In DevOps, developers can create servers with code rather than ask systems administrators to spin one up. In DevOps, developers can deploy their apps completely on their own, they don’t have to depend on anyone else. Plus, they can update smoothly because they’re not waiting for someone else.

That’s not to say that sysadmins are lazy, it’s simply that they have many other tasks on their plates.

See how DevOps makes everyone's jobs better by increasing responsibilities, trust and communication.

the EXCITEMENT in his presentation with all the BAM!!! DONE!!! BAM!!! DONE!!! is so enchanting. I am definitely more excited to learn more about DevOps right now. BAM!

This is a divisive message that is counterintuitive to the entire DevOps movement that aspires to break down the barriers between Development and Operations. DevOps is NOT about putting systems provisioning and release management completely in the hands of Developers thru "infrastructure as code." It is about working WITH operations to automate and streamline the end-to-end pipeline in a way that meets everyone's goals and standards. DevOps aims to break down barriers between traditionally silod'd disciplines, not to perpetuate them or create new ones.

Best explanation of Devops... Period!!!!

This video is super cool. I felt like I'm going back to college to attend my most favorite lectures.

[Brofabloke]

I just LOLd so hard with the "Sysadmins work normal hours thing" even with DevOps.

[TigerOscar]

This is the best explanation of DevOps I have ever seen!!!
I have used RedHat Satellite for automation but I really want to use Chef...

Nice video, thanks. On the part where you explain how chef server works you explained as the push method which is how ansible works by default. Where is by default Chef (like puppet as well) works on pull method. The nodes periodically ask the chef server :" Is there anything new for me, if yes give it to me"

I want to be able to see the results of each GUItest-project seperately in CatLight ( tfs-alerts.com ).
My idea on how to solve this is to have them as seperate releases for each GUI-testproject. This would make it possible to have them separetely in CatLight.

What Sysadmin would cheer this? "Yeah, i am not needed anymore!" :-D
Every step of automation means less people.

[KokLiangLim]

which means for employers, a devops is one that can do both. or sysadmins getting less jobs due to many developers thinking sysadmins can be easily taken over and redundant in their opinion since they are going to do more... sadly i think the world has been always favoring developers/programmers more than sysadmins just because they always think we write software, u use software, without us, you are nothing, but now with all the SDN stuff, cloud stuff bla bla, basically sysadmins will soon matters no more.

Who says Sys ad works on normal hours?

[ragheedr]

Darn grumpy system administrators? seriously?!
