How new podcast Command Line Heroes frames agile and DevOps

Red Hat has joined the ever-growing listing of fantastic tech podcasts with their new enterprise, Command Line Heroes.

In the primary two episodes, developer and host Saron Yitbarek tells the tales of how open supply software program and Linux gained momentum within the 80s and 90s. Then, within the subsequent 4 episodes earlier than the season finale, she provides transient but highly effective histories of agile, DevOps, containers, and the cloud.

Let’s check out the agile and DevOps episodes. Next time, I am going to transient you on containers and the cloud episodes.

The catalyst

With the arrival of the web, corporations wanted to ship providers and purposes lightning quick. “It’s all about faster time to market, increased agility, doing more iterative, rather than longer-term big pieces of work,” stated Richard Henshall, an Ansible product supervisor.

Developers had been the heroes and heroines who rode in to save lots of the day, and the position of the developer rose to prominence and status prefer it by no means had earlier than. As with any change of this magnitude, the processes by which builders labored had been analyzed, tried, examined, and reimagined. Enter two large modifications to the best way builders would work shifting ahead: agile and DevOps. 

First, agile

The agile technique was born at a software program improvement retreat in Utah through the winter of 2001. There, the manifesto was drawn up, and its listing of principles begins:

“Our highest priority is to satisfy the customer through early and continuous delivery of valuable software. Welcome changing requirements, even late in development. Agile processes harness change for the customer’s competitive advantage.”

Agile continues to realize adoption by builders as we speak, and the favored TV present Silicon Valley produced this clip on agile (and scrum):

Then, DevOps

Here’s the setup.

Jonah Horowitz, who works for the Reliability Engineering crew at Stripe, describes the issue this fashion:

“The operations team is often measured by uptime and reliability, and one of the biggest ways to increase uptime is to decrease the amount of change in the system. But of course, releasing new features is changing the system, and the software engineers who are doing product work are incentivized to ship as many features as quickly as possible. So you set up this conflict between dev and ops when you’ve got these separate roles.”

Scott Hanselman, principal program supervisor for .NET and ASP.NET at Microsoft, describes the answer this fashion:

“The Wikipedia entry from 2008 that defines DevOps is definitely excellent. So, it is a set of practices that’s supposed to cut back the time between committing a change and that change going into manufacturing whereas guaranteeing high quality. So if you consider, hey, I checked in some code. It’s Tuesday and that can be going out within the June launch. That sucks. That could be not steady integration. That could be a couple-of-times-a-year integration.

If you may have an excellent wholesome DevOps system, when you’ve achieved the set-up practices, then you’ll be constantly integrating into manufacturing. So it is, what are you able to do? What greatest practices are you able to outline, are you able to create, that can let you get it? So, I checked in some code on Tuesday and it is in manufacturing on Thursday. Now this is the essential half—pause for impact—whereas guaranteeing prime quality.”

Gordon Haff, a senior supervisor at Red Hat, talks about what it takes to do DevOps proper:

“You really need a whole new ecosystem of tooling to do DevOps most effectively. What we see is this huge collection of new types of tooling and platforms that DevOps can make use of. They’re really all coming out of open source.”

To hear extra about how builders and IT leaders addressed the problems of pace and mindset with DevOps practices, plus the position automation performs, listen to Episode 4.

Further studying

I am going to conclude this wrap-up with some nice hyperlinks and additional studying that I felt had been essential to incorporate.
