DevOps Protocols: Start Small

  • submit to reddit

 Imagine you want to introduce automated configuration management to your organization. You’ve read all the books and even visited a great conference where you heard a lot of success stories. “It’s really time to get our servers under control” you think. But how do you get started?

The over ambition trap

You’re highly motivated and the picture of having all your server configurations automated is as crystal clear as your brand new Retina display. It’s time to get moving. You start convincing your colleagues that it’s a great idea. But as soon as you talk to your manager, you feel like you’ve been downgraded to an old CRT monitor. Where you see challenges and opportunities, he only sees risks and efforts. Your grand vision crumbles under its own weight and you’re back to square one. Even worse, you’re so burnt and frustrated that you know a second attempt would be next to impossible.

The starvation trap

But what if your manager said “Go for it”? You start setting up the basic infrastructure and automating the first few services, but things are harder than expected. It takes more time and some code gets really ugly. Not only is it necessary to master the configuration management tools but you have to learn a lot of software development practices as well. You’re already partially burnt out from the effort of convincing your company this is the “next big thing”, but you encounter more problems and start to slow down. Your colleagues start complaining and you hardly dare face your manager anymore. One day you realize that the task is too big and that the benefit of having a fully automated data center is too far away. You give up. Game over.

How starting small can save your day

You have the grand vision. But instead of trying to automate everything at once, you just get user management automated. Your manager sees the immediate value and you get started. After a couple of days you’re ready to roll out your code to the first staging server. And because the impact of your automation attempt is limited you’re able to roll it out to production a few days later. This is a small but great success. You’ve solved a real issue in no time and people see the value of your approach. The success gives you wings and you attack the next challenge: bringing one server under automated configuration management. And after that you take up the next and the next. Every success adds to your creditability and gives you more energy to take on bigger and bigger challenges. This is the power of starting small.

Have you ever failed because you started too big? Please share your story in the comments below.

Yes , i agree with you.

when we do the practice of continuous delivery at BAIDU which is biggest chinese search engine. we choice one service of our system, change it first and impact just a few users.  when we success in these few services ,we involve more severvices , then we did it.

Start Small the same to Baby Step... I like the method when we want make some change!

Starting too big can make the entire project to collapse, that`s why it`s very important to think about every aspect and start building the project in small steps. MMedia Powers is a marketing and advertising agency that helped me to increase the profits of my on-line shopping website, they gave me a lot of great ideas that were easy to put into practice.
