IBM DevOps Code ClearCase vs. Red Hat Satellite

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

Red Hat Satellite works amazingly with servers that need more control over their packages. For one or two servers that you're just doing "dnf update" Red Hat Satellite is way overkill.

• 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.

• Patches
• License Management
• Dashboards / Visibility

• Extremely buggy.
• Sometimes the repository gets locked for no reason.
• Slow.

• I woud love for it to provide the same functionality for non-RHEL OS's
• Containerized Installation
• Simplified workflow setup

When you're first getting into the platform, the GUI can be a little confusing. It takes a little while to get accustomed to where everything is, and what everything is used for. I highly recommend prior training / classes before diving into the platform. This will ensure a better transition into the platform, and more likely to use more features of it overall due to the new knowledge gained

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.

• We have been able to automate the update process to not require after-hours monitoring.
• Centralizing updates has greatly reduced the overall time servers are down and processing their individual updates.
• We are able to bring our own RPM packages in and stage them in the same deployment model as official Red Hat packages.
