Automated Deployment

If there is one golden rule in programming, it should be to automate as much as possible. Automated Deployment ensures that the path your code takes from development through to production does not break its functionality. Read more to learn how to make Automated Deployment a regular part of your Continuous Deployment.

What Is an Automated Deployment

Automated Deployment is a practice that allows you to ship code fully or semi-automatically across several stages of the development process - from initial development right through to production. It contributes to more efficient and reliable deployments.

How do you know that the path your code takes from development to production does not break its functionality? To ensure functionality you should automate as much as possible. Automation requires a deployment pipeline, which is the process of taking code from your version control environment (for example, git) and making it available to users of your application.

We can classify Automated Deployment approaches into different categories, according to the level of automation coverage across environments:

  1. Continuous Integration Continuous Integration is the practice of daily integrating code changes. Everything that has been developed integrates daily. Each integration is then automatically verified and tested to detect possible errors. For more information, see Continuous integration.
  2. Continuous Delivery Continuous Delivery is the practice of keeping the code ready to deploy at any given time. Continuous Delivery is an extension of the continuous integration to automate release to the staging environment. Continuous Delivery ensures a a production-ready version of your build at any time. This is often required by financial institutions and other customers who require little or no "down time".
  3. Continuous Deployment Continuous Deployment is the practice of fully automating the entire process of the deployment pipeline. Every change in the source code is deployed to production automatically and without explicit approval from a developer. This is the quickest method of deployment, however errors can cause issues and possible downtime.

Why You Might Want the Deployment to Be Automated

Automated Deployment helps your team with:

  • Reduced possibility of errors Manual deployment is error-prone. Any process involving human input introduces the possibility of errors. Assignment to repetitve manual deployment tasks can harm employee morale.
  • Saving time Manual deployment is time-consuming. The job is often assigned to testers and developers in a development team who can otherwise spend their time working on improving the application.
  • Consistency and repeatability Once configured, the process is the same every time you initiate release. It contributes to more frequent and stable releases. This consistency greatly assists in diagnosis of errors as it reduces the possible variables.

How to Implement Automated Deployment

Follow these steps to set up a basic deployment pipeline:

  1. Set up a Continuous Integration server
    • Choose an existing server, such as Jenkins, or go.cd.
    • Set up your first build (a link to your source code, for example, on GitHub and a command to build the application)
    • Ensure that it runs every time a change is checked into source control.
  2. Set up a few test suites
    • Set up a separate build for each test suit and link the builds like dominos, so that each is triggered by the one before it. This way you see very quickly if there is some problem - the problematic code change stops at the first test that recognizes it and does not go any further.
  3. Add a deployment step
    • On your Continuous Integration server, set a build that runs your script to deploy your application to a testing or staging environment. Ensure that it runs only when all the tests pass.

Common Pitfalls of the Automated Deployment

  • Exaggerated reliance on the Automated Deployment It is always good to have an alternative strategy to avoid being stuck when your Automated Deployment configuration is broken.
  • The project is too small Implementing Automated Deployment can be time-consuming. Ensure that you do not spend more time implementing it than actually developing the product.
  • Rigid pipeline design Rigid pipeline prevents the team from optimizing their processes. Pipeline should be structured, flexible, and able to incorporate sudden changes.
  • Long and slow deployment pipelines There are too many steps between code commit and deployment. Ensure that every step is necessary.
