What is an automated application deployment tool?
An automated application deployment tool is software that automatically handles moving code changes through build, test, and release processes without manual intervention.
Instead of writing complex scripts or issuing manual commands, developers commit code, and the deployment tool “picks up” the changes.
Today, teams are under pressure to release updates quickly without sacrificing reliability. This is where automated deployment comes into play.
But exactly what is automated deployment, and why are automated application deployment tools becoming essential in DevOps?
In this comprehensive guide, we’ll explore what automated deployment means, how an automated application deployment tool works, and where these DevOps deployment tools fit into your pipeline.
By the end, you’ll understand the key benefits of using such tools and how they can transform your software delivery process.
What is an automated deployment Tool (and how does it work)?
Automated deployment tools are software solutions that streamline the process of releasing applications by automating the steps involved in deployment.
In simple terms, they take your code from version control and automatically get it running in the target environment (testing, staging, production) with minimal human effort.
These tools handle tasks like packaging the application, configuring environment settings, and rolling out updates to servers or cloud platforms.
The goal is to get software from development into users’ hands quickly and reliably.
How it works?
Typically, automated deployment is triggered by an event, for example, when new code is merged into the main branch.
Here’s a simplified look at how an automated deployment tool works:
- Code is Committed: A developer commits code changes to a version control repository (like Git). This act can trigger the deployment pipeline automatically.
- Build and Test: The tool kicks off an automated build process, compiling the code and then running tests (unit tests, integration tests, etc.) on the new build. If any tests fail, the process stops here.
- Staging Deployment: If tests pass, the tool deploys the new build to a staging environment (a production-like environment) for further testing or approval. Configuration settings (database strings, API keys, etc.) for that environment are applied automatically, often using configuration management to ensure consistency.
- Production Release: Upon approval (or automatically, in a fully continuous deployment setup), the tool releases the tested build to the production environment. This might involve updating servers, containers (e.g. Kubernetes pods), or serverless functions with the new code.
- Post-Deployment Tasks: A good deployment tool will also handle post-release steps like running database migrations, clearing caches, and even monitoring the deployment. Many tools collect metrics on the deployment (success, duration, any errors) for tracking and improvement. If something goes wrong, the tool can often roll back to the previous stable version.
Key Benefits of Automated Deployment Tools
Automated deployment tools offer speed, reliability, and efficiency
compared to manual releases. By eliminating manual steps, teams can ship updates more quickly and more often.
Automated releases cut the typical build-and-deploy time dramatically. for example, Forrester found that continuous deployment practices can reduce release cycle times by ~45%.
Standardised automation also ensures fewer human errors. Manual deployments are prone to mistakes (typos, forgotten steps, wrong configurations), but automation enforces the same scripts or pipelines each time, making deployments consistent and repeatable.
Other key benefits include:
- Reliability and consistency: Automation applies the same steps every time, reducing deployment failures. As Atlassian notes, automated deployments are “consistent, repeatable, and standardised”, improving reliability.
- Fewer errors and rollbacks: Automated testing and validation catch issues early, and built‑in rollback features (e.g. blue/green or canary releases) minimize downtime if something goes wrong.
- Increased development efficiency: Developers no longer fiddle with manual uploads or YAML scripts. Instead, they focus on code, while the tool handles builds and pushes. Team productivity rises as release tasks become “push-button” operations.
- Scalability: Most deployment tools can provision, update, and scale infrastructure automatically as needed. For example, AI-powered platforms like Kuberns autoscale apps based on demand, also saving cloud costs (Kuberns claims up to 40% AWS savings).
- Better collaboration and visibility: A managed pipeline provides logs and dashboards. Everyone sees what’s being deployed, and permissions/approvals can be built in. This improves team coordination and auditability.
Where automated deployment fits in the DevOps Pipeline?
Automated deployment tools fit squarely within the DevOps pipeline, especially at the CI/CD stage. In DevOps, a pipeline is a series of automated steps that take code from version control all the way to production.
DevOps pipeline is “a set of automated processes and tools that allows developers and operations professionals to collaborate on building and deploying code”.
Within this pipeline, continuous integration (CI) builds and tests code, and continuous delivery/deployment (CD) packages and releases it. Deployment automation is the heart of the CD phase: it automatically moves code changes into test, staging, and production environments.
In practice, the steps typically look like this:
A developer commits code (e.g. to Git); this triggers the pipeline to build the application and run automated tests; if everything passes, the deployment tool pushes the build to the staging or production server, often with an approval gate for production.
These steps are outlined as an automated workflow: the commit triggers a build, the code is tested, then deployed to staging, and upon approval, it goes live.
Automated deployment tools manage these transitions seamlessly.
They integrate with version control (Git), container registries (Docker), and cloud APIs to deploy infrastructure as needed, all as part of the continuous delivery flow.
By removing manual hand-offs, deployment automation keeps the pipeline flowing smoothly. Atlassian emphasizes that “automated deployments are vital in streamlining the DevOps pipeline”: they reduce manual errors and shorten iteration cycles.
Where it fits?
Typically, deployment automation is the final stage in the CI/CD pipeline.
Once code is validated, the automated deployment tool takes over to configure servers or cloud containers, perform the rollout (e.g. blue/green update or canary), and verify the release.
It works hand-in-hand with the earlier build/test stages.
For example, Atlassian notes that deployment automation “focuses on distributing [software] components to designated environments”, moving code safely toward end users.
In summary, automated deployment tools turn the end of the pipeline into a push-button process that directly links development to production.
