What tools & tech are devops engineers using today

via GIPHY

I just stumbled upon Graham King’s blog, and I’m liking his writing. He wrote an excellent piece a developer goes to a DevOps conference.

I’ve been to plenty of Unix & operations type conferences over the years, so topics don’t surprise me. But hearing about a developer’s experience brings a new perspective and some great insights.

1. Tools change but mindset stays the same

Some talk about Devops as doing away with operations. Those job roles just aren’t necessary anymore. Well maybe for a small firm, or maybe shops that have pushed 2-pizza agile to the max. But handing the operations duties to developers has limitations. As I mentioned here (the difference between dev and ops is a four letter word…) these different job roles have different mandates.

It’s like an architect can design a building, and it can be a very beautiful house. But a super or building manager keeps it running over the years. He or she knows what to look for in cracked roofs, knows how to keep rodents & pests at bay, knows how to repair and maintain & stay ahead of the game.

In that analogy, the architect is the developer, while the super or building manager is the operations team. They’re two different mindsets, rarely shared in one person.

2. Being on-call is a b*tch

I could write volumes about being on-call. Getting woken up in the middle of the night, because someone pushed broken code is no fun. What’s more broken can have different meanings.

Broken can be something QA should catch, like a button doesn’t work or there’s an issue with some browser. It could also be that some new product feature doesn’t work properly.

But from the ops perspective, broken could also be some new feature doesn’t scale. It makes a million API calls, or makes a servless call that times out. These types of broken are much harder to test for.

This is also why traditionally operations and development were two different teams. Because from the vantage of the business, they had different mandates.

Ops was mandated with stability. So they don’t want change. Change breaks things, and wakes you up at 3am.

Devs are mandated with features changes, and product improvement. So they naturally bring change to the table.

And between the two we search for balance. I wrote a piece that hit on exactly these points the difference between dev and ops is a four letter word…

3. The kingmaker tools

Kubernetes – you’ve heard of it, you’re probably using it. Devs package their app as a docker container, and ops push that container through CI/CD pipeline, and finally orchestrate & deploy with kubernetes. Seems like the *only* way to do things these days, right?

But some argue Docker may not be right for everyone and certainly this stack brings a *lot* of complexity for small organizations.

Terraform I’m a big fan of this technology. Once you’ve captured your entire stack in code, you can version it, check it into git, and manage it like any other asset. That’s great, but there are so many other benefits. You can easily deploy that same stack in another region, or tweak it to create dev, stage and production. Cool stuff!

Ansible All those BASH scripts you have sitting around? Check them into version control before it’s too late! One great thing about Ansible is with slight tweaks and can run those bash scripts almost as-is.

And for ops who already have experience with managing things by hand, you can get up to speed with Ansible, in a few days. The learning curve isn’t as tough as Puppet or Chef, and brings many or most of the benefits.

Packer Here’s another cool tool. Chances are all those AMI’s that Amazon has pre-baked, need tweaks for your setup. Now you could do all that work post spinup with Ansible. And that’s fine. But it’ll be slower, and possibly prone to breaking if the base AMI changes.

Enter Packer, another great tool from the folks who brought us Terraform, Hashicorp. This tool allows you to write yaml files that then build AMI’s. You can then use your pipeline and other automation tools to automate those as well. Cool !

Why you should attend Percona Live 2012

What I loved about Percona Live 2011

Last year I was excited to go to Percona Live for the first time in NYC. I arrived just in time to hear Harrison Fisk from Facebook speak about some of the awesome tweaks they’re running with MySQL there. It’s not everyday that you get to hear from top MySQL engineers how they’re using the technology and what their biggest challenges are. If they can make MySQL hum, so can the rest of us!

Afterward, outside in the foyer, I ran into all sorts of luminaries in the MySQL space. Percona folks like Peter Zaitsev & Vadim Tkachenko, plus other big names like Baron Schwartz, Harrison, and Ronald Bradford. I ran into people from firms like Yahoo, Google, Daniweb, Pythian, SkySQL & Palomino.

What to expect at Percona Live NYC 2012

This years event next month features rockstar engineers from an incredible lineup of firms including Etsy, New Relic, Youtube, Paypal, Tumblr, SugarCRM, Square, and of course a few from Percona themselves. I promise you this, these talks won’t be salesy or in any way a waste of your time and money. They will be thoroughly technical talks, with cutting edge insights and advice from those in the trenches using the technology everyday.

If I wasn’t heading to Oracle Open World for the publishers seminar & MySQL Connect, I would most certainly be there. In fact I had originally been slated to talk about point-in-time recovery in MySQL. Oh well, I’m sure I’ll catch you at the Percona Live in April 2013.
