Release gates

Release gates give you more control over the start and completion of the deployment pipeline. They're often set up as pre-deployment and post-deployment conditions.

Think of downtime of a database server or an update of an API. It takes much time and effort, and the only thing needed is a signal if the release can continue. 

You can create a mechanism where people press a button on a form when the release can't advance. 

When the release starts, it checks the state of the gate by calling an API. If the "gate" is open, we can continue. Otherwise, we'll stop the release.

By using scripts and APIs, you can create your release gates instead of manual approval. Or at least extending your manual approval.

Approvals and gates give you more control over the start and completion of the deployment pipeline.

Whereas, a quality gate is the best way to enforce a quality policy in your organization. It's there to answer one question: can I deliver my application to production or not?

A quality gate is located before a stage that is dependent on the outcome of a previous stage. A quality gate was typically something that a QA department monitored in the past. They had several documents or guidelines, and they verified if the software was of a good enough quality to move on to the next stage.

We need to reconsider the notion of quality gates and see how we can automate these checks as part of our release pipeline

Many quality gates can be considered.

  • No new blocker issues.
  • Code coverage on new code greater than 80%.
  • No license violations.
  • No vulnerabilities in dependencies.
  • No further technical debt was introduced.
  • Is the performance not affected after a new release?
  • Compliance checks

    • Are there work items linked to the release?

    • Is the release started by someone else as the one who commits the code?

Defining quality gates improves the release process, and you should always consider adding them.

What is release, and what is a deployment?

T o understand the concepts and the technical implementation in many tools, you need to know how tool vendors define the difference between a release and a deployment. A  release  is a package or container containing a versioned set of artifacts specified in a release pipeline in your CI/CD process. It also includes a snapshot of all the information required to carry out all the tasks and activities in a release pipeline, such as: The stages or environments. The tasks for each one. The values of task parameters and variables. The release policies such as triggers, approvers, and release queuing options. On the other hand,  Deployment  is the action of running the tasks for one stage, which results in a tested and deployed application and other activities specified for that stage. Starting a release starts each deployment based on the settings and policies defined in the original release pipeline. There can be multiple deployments of each release, even for one stage. ...

Considerations for deployment to stages

When you have a clear view of the different stages you'll deploy, you need to think about when you want to deploy to these stages.  Continuous Delivery is about deploying multiple times a day and can deploy on-demand. When we define our cadence, questions that we should ask ourselves are: Do we want to deploy our application? Do we want to deploy multiple times a day? Can we deploy to a stage? Is it used? A typical scenario we often see is continuous deployment during the development stage. Every new change ends up there once it's completed and builds. Deploying to the next phase doesn't always occur multiple times but only at night. When designing your release strategy, choose your triggers carefully and consider the required release cadence. Some things we need to take into consideration are: What is your target environment? Does one team use it, or do multiple teams use it? If a single team uses it, you can deploy it frequently. Otherwise, it would be best if you were a ...

Explore Release Pipeline

A release pipeline takes artifacts and releases them through stages and finally into production. The first component in a release pipeline is an artifact: Artifacts can come from different sources. The most common source is a package from a build pipeline. Another commonly seen artifact source is, for example, source control. A manual trigger, where people start to release by hand. A scheduled trigger, where a release is triggered based on a specific time. A continuous deployment trigger, where another event triggers a release. For example, a completed build. Furthermore, a release pipeline has a trigger: the mechanism that starts a new release. A trigger can be: Another vital component of a release pipeline is stages or sometimes called environments. It's where the artifact will be eventually installed. You can have many stages (environments); part of the release strategy is finding the appropriate combination of stages. Another component of a release pipeline is approval. People ...
