Learn DevOps

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

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 infrastructuree.g: to run a specific version of software or database.
• Your client/boss has instructed youto 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 teamsin order to improve collaboration and productivityby automating infrastructure, automating workflowsand continuously measuring application performance."from: "What is DevOps?" by RackSpace

Who?

Everyone that wants to seriously consider/call themselfa "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 deployedhttps://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-usedinfrastructure/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

• Node.js with Dokku:nodejs-digital-ocean-centos-dokku.md
• Node.js "Zero Downtime" Production Deployment with PM2:nodejs-pm2-zero-downtime.md

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 havebuilt, 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, pleaseopen an issueand we will attempt to help!
