Microservices act as an application entity or software ecosystem that acts as a team to improve workflow. Each part of the workflow works through its individual application. Ultimately, this ecosystem will make things run more smoothly. This is a long journey from one size fits all software that did it all.
Of course, for so many smaller applications, a code change can have an impact on the entire system due to inter-application dependencies. Code that may work well in one application may cause another crash. This is where Zuul comes in. Because all applications are interdependent, Zuul ensures that breaking broken code is a thing of the past.
Ultimately, the interdependence between projects in Zulu allows users to be accurate about their dependencies in all projects. Continue reading for more information.
Testing between projects
If projects are as close as two peas in a bar, it is imperative that any changes that pass through the gate are adequately tested with other relevant versions of the projects that are currently waiting at the gate. If these are combined poorly, some software may break the new code.
You can ensure that broken code does not merge by defining projects in a shared queue with well-thought-out piping. If there are changes in the project, they move to a shared queue, where all changes are tested together to ensure that the structures are not broken. There are no restrictions on shared change queues in a dependent pipeline. This task ensures that groups of related projects can share change without disrupting other projects.
Dependence between projects
One of the features of Zuul is that it allows users to define certain dependencies on their projects. With a special footer, it makes the change dependent on another change in any archive known to Zuul. This means that your first change may depend on the second, but your second change may not depend on your first change.
The directed acyclic diagram (DAG) behaves in the same way as the interdependencies between Zuul’s projects. It shows a one-way dependence on changes in different Git repositories. If you are using a Gerrit-based project, this footer must be included in the Git commitment message. Gerrit acts as a code checking system and its controller supports sources, triggers, and vendors. Just a note: if you use an older syntax that specifies dependencies with Gerrit change IDs, it will still be supported, but will be removed in future versions. Additionally, if you are using a GitHub-based project, you must add this footer to the description of the draw request. GitHub supports the same three functions as Gerrit. It can also interact with the public GitHub service and GitHub’s local local installations.
Finally, thanks to the dependencies between the projects in Zuul, micro services are able to work exactly as they should. If you are an enterprise-class organization with large and complex software, Zuul is the ideal option. With the benefits of aggregation, interdependence between projects, and concurrency, Zuul helps you drive your workflow in a way that encourages optimal results. Contact the team experts learn more.
