In easy words, "DevOps Assembly Lines" could be a "pipeline of pipelines." DevOps assembly lines are targeted at automating and connecting activities performed by several groups as part of software development phases like continuous integration for the developer, infrastructure and configuration management for an operator, automation script for the testing team, Security-related for SecOps, and last and enabling CI. Assembly lines are used to organize day to day tasks from all teams that collaborate for the project's dignity. In short, DevOps assembly lines help us to automate and scale end-to-end workflows of application across all teams and tools, which enable continuous delivery. The Future is the DevOps Assembly line.
Continuous Integration Pipelines
Before the DevOps Assembly Line, we use Continuous Integration (CI) pipelines, which is defined as a simple process of automating build and unit tests for each code change done by any team.
Types of CI Pipelines
Discussed below are the types of CI Pipelines for enhancing your knowledge about Continuous Integration.
1. The Classic CI:
The Classic CI all build and test instructions were included in a single job, and instructions were executed sequentially. If all instructions run successfully, only then CI was successful.
2. Continuous Integration with Stages:
The above diagram shows that an application is deployed on different stages (dev/uat/prod). In the CI approach, we have to write three different jobs for a complete CI process (build, test, deploy), and all the jobs depend on the successful completion of the previous job, which means the test will run if build a job was successfully run the same as deploy.
3. Continuous Integration with Parallel Stages:
Pipelines give us a lot of flexibility and control over our process by converting the jobs in stages. Now we don't need to create multiple jobs for different phases of CI/CD. We need to create a single job with all the stages with flow control.
4. Continuous Integration with Forked Stages:
The CI pipeline's major disadvantage is as application architecture to evolve rapidly, from N-tier to Service-Oriented Architecture to Microservices, and the current linear approach to software delivery cannot handle the complexity of Microservices or Serverless architectures. Why was there the Need for CI with stages, CI with parallel stages, and CI with forked stages? Know below!
Defining the CI with stages can get outcomes quicker without waiting for the complete workflow to finish.
Running stages can test your code on various environments, language versions and get faster feedback.
The next stage of your CI will be decided based on your previous stage results.
Knowing DevOps Assembly Lines
There is a lot to know when it comes to DevOps Assembly Lines. The zipped images below depict the same.
So how do DevOps Assembly Lines and CI Pipelines support the functioning in enterprises? Know below!
Capability to immediately establish workflows across multiple pipelines.
Integrations with all popular source control systems.
Enabling rapid changes and scaling for various applications or microservices.
Abstractions of all delicate information like passwords, tokens, keys, etc.
Roles and permissions restricting assembly line and pipeline action.
Metrics and Analytics across pipelines to help identify bottlenecks.
Visibility into each pipeline and stage, including logs, status, and versioned data.
It handles all DevOps infrastructure, including spinning VMs and containers up and down as required.
Roles and permissions restricting assembly line and pipeline actions.
Release automation features such as semantic versioning of packages.
Ability to pass state and other information while triggering dependent pipelines.
Concluding a Holistic Strategy
DevOps assembly lines aim to automate tasks and define easy workflows across multiple pipelines, removing inefficiency and unnecessary human-dependent steps. It provides an ideal situation for your company’s application teams. Developers push code to a repository. This code will be integrated, tested, deployed, tested again, merged with infrastructure, go through security and quality reviews, and ready to deploy with confidence.
