Learn DevOps

Learn the craft of "DevOps" (Developer Operations) to easily/reliably deploy your App and keep it Up!

devops-process

Why?

You should learn more "advanced" DevOps if:

  • You / your team have "out-grown" Heroku (e.g: your Heroku bill is more than $100/month)
  • You want "more control" over your infrastructure e.g: to run a specific version of software or database.
  • Your client/boss has instructed you to use a specific "cloud" provider.
  • Curiosity to extend your "back end infrastructure" knowledge to be a more "well-rounded" developer.

What?

"DevOps integrates developers and operations teams in order to improve collaboration and productivity by automating infrastructure, automating workflows and continuously measuring application performance." from: "What is DevOps?" by RackSpace

Who?

Everyone that wants to seriously consider/call themself a "Full Stack" Developer must know how to deploy, secure and monitor their app on their chosen infrastructure.

How?

Over the years we @dwyl have deployed/managed Apps, both our own and those of our clients, on a wide variety of infrastructure and platform providers.

Most of our Apps have been deployed to Amazon Web Services ("AWS") e.g: https://www.sciencemuseum.org.uk
We have several clients who use (and love) Heroku e.g: https://www.ellenmacarthurfoundation.org
For the National Health Service (NHS) in England, (who have a major contract with Microsoft) we deployed https://www.healthlocker.uk to Azure.
We have clients who still own their own "Bare Metal" Servers.

Provider-Specific Guides

We have produced a guide for each of our most-used infrastructure/platform providers:

  • AWS: https://github.com/dwyl/learn-amazon-web-services
  • AWS Lambda: https://github.com/dwyl/learn-aws-lambda
  • Azure: https://github.com/dwyl/learn-microsoft-azure
  • Heroku: https://github.com/dwyl/learn-heroku
  • Linode: linode-setup.md
  • DigitalOcean: nodejs-digital-ocean-centos-dokku.md

Node.js

If you would like to see a guide for a different service provider, please open an issue with your suggestion(s): https://github.com/dwyl/learn-devops/issues

Testing, Continuous Integration & Delivery

Deployment is what you do with your app once you have built, tested and documented it.

If you are unfamiliar with Test-Driven Development (TDD), please see: https://github.com/dwyl/learn-tdd

Next you should be proficient with Continuous Integration. For that we recommend using Travis-CI, see: https://github.com/dwyl/learn-travis

Using a Different Cloud Infrastructure Provider?

While this tutorial has focussed on using Linode, we @dwyl have experience of using several infrastructure providers:

  • Amazon Web Services: https://github.com/dwyl/learn-amazon-web-services
  • Azure: https://github.com/dwyl/learn-microsoft-azure
  • Digital Ocean: https://github.com/dwyl/DigitalOcean-Setup
  • Heroku: https://github.com/dwyl/learn-heroku

if you have a question specific to using Linode or one of the other "cloud" providers, please open an issue and we will attempt to help!
