IBM DevOps Code ClearCase vs. Red Hat OpenShift Dev Spaces

IBM Rational ClearCase might be better suited for a smaller / simpler code base. Larger code bases really slow it down... but then again there are better alternatives out there for source control

We have a team of 500 people so it's most reliable and scalable if any new joinees. That way user's can directly create their own workspace and start working and share the work stack throughout development teams securely, to update and modify any upcoming events. The best thing about Red Hat Workspace is it's simple, with all Runtime libraries pre-installed, so no need to request a platform from Azure or any other platform provider just log in and start creating a workspace. It has version control so can easily import GIT projects can start work without worrying we don't have Java, Python or any other platform not installed just select the platform needed and start working.

• Rational ClearCase is excellent for handling versioning and branching. No other tool I've used has the depth that ClearCase has when it comes to handling complex branching scenarios and identifying where certain versions of particular files are within a particular configuration.
• Rational ClearCase handles parallel development of many dependent applications really well.
• The use of ClearCase Views to switch between projects and configurations is extremely convenient as opposed to the local workstation model of the competitors.

If development is centrallized to one location and your company releases hundreds of customized versions of your software per year, then ClearCase is the best tool for managing the complexity of multiple versions of customized software. If your company has globally distributed development, then I'd recommend Team Foundation Server over ClearCase. If your organization uses Agile Methodologies, then I'd recommend TFS with GIT.

• Managed code versioning for many years.
• Only one person can edit code at a time - slows processing down.
• IBM is an expensive product to support.
