Improved agility and time to market with CI/CD enhancements

The CI/CD pipelines in GitLab ( /products/gitlab-reviews ) are highly valuable. Another important feature is the single source of repository, allowing efficient repository management and source code management. GitLab provides manageability by allowing us to manage source code effectively through separate repositories. Additionally, GitLab enables the creation of individual CI/CD pipelines for each repository, making software more agile. By integrating GitLab as a DevOps platform, we have enhanced agility, improved our time to market, and different teams can work collaboratively on various projects.

Senior Lead Engineer - Product Security at a manufacturing company with 1,001-5,000 employees

Helps us complete testing more quickly by eliminating many unwanted test cases

Sometimes, when we are testing embedded devices, when we trigger the test cases, the target will crash immediately. It is very difficult for us to identify the root cause of the crash because they do not provide sophisticated tools on the target side. They cover only the client-side application, and from that we can generate automated test cases, but what happens on the target device, what is the reason for the crash, for that we have to do manual debugging. They do not have diagnostic tools for the target side. Rather, they have them but they are very minimal and not very helpful. They can improve a lot on that.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Continuous integration with deployment is very powerful, which is a significant reason for migrating from TFS to GitLab."

"The most important features of GitLab for us are issue management and all the CI/CD tools. Another aspect that I love about GitLab is the UI."

"The most valuable functionality of GitLab, for me, is the DevOps. Besides the normal source control based on Git, I find the Auto DevOps features most important in the solution."

"I recommend GitLab for DevOps engineers."

"It is user-friendly, easy to use, and easy to administer."

"Their CI/CD engine is very mature. It's very comprehensive and flexible, and compared to other projects, I believe that GitLab is number one right now from that perspective."

"GitLab is a solution for source code management, container registry, pipelines, testing, and deployment."

"It is very flexible and easy because you can store data on cloud."

More GitLab pros

"The product is related to US usage with TLS contact fees, i.e. how more data center connections will help lower networking costs."

"We have found multiple issues in our embedded system network protocols, related to buffer overflow. We have reduced some of these issues."

"Whatever the test suit they give, it is intelligent. It will understand the protocol and it will generate the test cases based on the protocol: protocol, message sequence, protocol, message structure... Because of that, we can eliminate a lot of unwanted test cases, so we can execute the tests and complete them very quickly."

Cons

"Merge conflicts and repository maintenance could improve. If there is someone new to the system they would not know if there is a conflict."

"For as long as I have used GitLab, I haven't encountered any major limitations. However, I think that perhaps the search functionality could be better."

"There is room for improvement in GitLab Agents."

"The pricing has been substantially increased, which is a major concern."

"The licensing model could be improved to be more accommodating in terms of user numbers and costs."

"Currently, GitLab is not easy to scale because GitLab has specific deployment instructions. We deploy it on one of the VMs."

"I used Spring Cloud config and to connect that to GitLab was so hard."

"We have only seen a couple of issues on Gitlab, which we use for building some of the applications."

More GitLab cons

"Codenomicon Defensics should be more advanced for the testing sector. It should be somewhat easy and flexible to install."

"Sometimes, when we are testing embedded devices, when we trigger the test cases, the target will crash immediately. It is very difficult for us to identify the root cause of the crash because they do not provide sophisticated tools on the target side. They cover only the client-side application... They do not have diagnostic tools for the target side. Rather, they have them but they are very minimal and not very helpful."

"It does not support the complete protocol stack. There are some IoT protocols that are not supported and new protocols that are not supported."

Pricing and Cost Advice

"I don't mind the price because I use the free version."

"The solution is based on a licensing model that includes technical support and is paid annually."

"My company uses the free version of GitLab, which is GitLab Community Edition. There is a licensed version also available for GitLab."

"GitLab is highly priced for smaller teams, but it's okay if considering a user base of thousands."

"This is an open-source solution."

"The price of GitLab could be better, it is expensive."

"GitLab is cheap."

"We are using the open-source version."

More GitLab pricing and cost advice

"Licensing is a bit expensive."
