Comparing self-hosted runners with shared runners in GitLab

When it comes to choosing between self-hosted runners and shared runners in GitLab, it’s important to understand the differences and consider your specific needs and requirements.

Shared runners are provided by GitLab and are available for all users to utilize. They are hosted on GitLab’s infrastructure and can be used by multiple projects simultaneously. Shared runners are convenient as they require no setup or maintenance on the user’s end.

However, they may have limitations in terms of performance and availability, especially during peak usage times.

On the other hand, self-hosted runners are runners that you set up and manage on your own infrastructure. This gives you more control and flexibility over the resources and environment used for your CI/CD pipelines. Self-hosted runners can be particularly beneficial for organizations with specific security or compliance requirements, as they allow you to keep your build and deployment processes within your own network.

One of the key advantages of self-hosted runners is their ability to provide faster build times and improved performance. Since they are dedicated to your projects, you don’t have to compete with other users for resources. Additionally, self-hosted runners can be customized to meet your specific needs, such as installing additional dependencies or tools required for your builds.

However, self-hosted runners also come with some considerations. They require maintenance and monitoring to ensure their availability and performance. You need to ensure that your infrastructure can handle the workload and scale as needed.

Troubleshooting issues with self-hosted runners may also require more technical expertise compared to shared runners.

In conclusion, the choice between self-hosted runners and shared runners depends on your organization’s specific requirements. If you prioritize control, customization, and performance, self-hosted runners may be the better option. However, if convenience and ease of use are more important, shared runners can be a suitable choice.

It’s recommended to evaluate your needs and consider the trade-offs before making a decision.
