GitLab is a single application that does everything from planning to monitoring. The advantages of a single application for are listed in the following paragraphs. These result in more results, happier developers, improved cycle times, and a great return on investment.
Other vendors offer a kit plane you have to assemble yourself, GitLab is a type certified aircraft.
You only have to login to one application. Users don't waste time logging in. You only have to set up one account. It is clear to users what account they should use. Due to less confusion phishing is harder.
GitLab does not require you to manage authorizations for each of its tools. This means that you set permissions once and everyone in your organization has the right access to every component.
Users don't have to set up or ask others to set up a project across applications. This can be a major source of delays.
With Auto DevOps your new projects have all the needed testing and deployment from the get go. And by having logging and security scanning happen automatically you reduce risk.
A single interface for all tools means that GitLab can always present the relevant context and you're not losing information due to constant context switching. Users don't have to switch between applications constantly. Furthermore, if you're comfortable with one part of GitLab, you're comfortable with all of GitLab, as it all builds on the same interface components.
Running GitLab means that there are is only one single application to install, maintain, scale, backup, network, and secure.
Updating GitLab means that everything is guaranteed to work as it did before. Maintaining separate components is often complicated by upgrades that change or break integration points, essentially breaking your software delivery pipeline. This will never happen with GitLab because everything is tested as an integrated whole.
GitLab uses a single data-store so you can get information about the whole software development lifecycle instead of parts of it. With multiple applications you not only have multiple databases but also different definitions, processes. Multiple data-stores lead to redundant and inconsistent data. You don't have to duplicate data nor do manual entry. There is a single source of truth without having to build a data warehouse.
Automated links between environments, code, issues, and epics provide a better overview of project state and progress. All information is realtime and there is a coherent set of concepts and definitions.
Using a single application means you don't have to integrate 10 different products. This saves time from your developers, reduces risk, increases reliability, and lowers the bill of external integrators. The flow is better since the more then 100,000 organization using GitLab use the same flow and more than 1800 people contribute to make it great. If you have a developer tool department they can now focus on other tasks to make your developers more effective.
You can deal with one vendor instead of multiple vendors pointing to each-other.
Your end user training becomes less complex; a multi-vendor environment means multiple trainers to manage.
We prefer to offer a single application instead of a network of services or offering plugins for the following reasons:
A single application across the complete DevOps lifecycle has unique, emergent benefits. Among them:
Emergent benefits are subtle and sometimes best described by example. Some examples are:
Conversational development carries a conversation across functional groups through the DevOps lifecycle, involving gatekeepers at every step. By providing relevant context, a feature that is only possible with an integrated solution like GitLab, we can reduce cycle time, making it easier to diagnose problems and make decisions.
Concretely, conversational development in GitLab means that a change can be easily followed from inception to the changes it made in performance and business metrics and feeding this information back to all stakeholders immediately.
Effectively, this allows cross-functional teams to collaborate effectively.
Review apps are the future of change review. They allow you to review not just the code, but the actual changes in a live environment. This means one no longer has to check out code locally to verify changes in a development environment, but you simply click on the environment link and try things out.
Only a tool that combines code review with CI/CD pipelines and integration with container schedulers (Kubernetes) is able to quickly create and shut down review apps and make them part of the review process.
Cycle analytics tell you how what your time to value, from planning to monitoring is. Only by having direct access to each step in the software development lifecyle, GitLab can give actionable data on time to value.
This means you can see where you are lagging and make meaningful change to ship faster.
Every GitLab projects comes with a container registry. That means there is no need for elaborate configuration to be able to use and push container images in CI. Rather, all you have to do is use a pre-defined variable in your CI configuration file (
Sometimes users ask if GitLab has particular module that contains a set of features. A modules-mindset results in narrowly-focused solutions and redundant features and abstractions. GitLab is a single application that solves entire use cases that might touch many parts of GitLab, without creating additional unnecessary complexity.
As GitLab breadth expands, but is maintained as a single application, new features are continually back-integrated into existing features. This means that existing features and the data that they have already generated over time accrue new value for very little cost in the context of the new features and their use cases.
