IBM DevOps Code ClearCase vs. National Instruments SystemLink vs. SUSE Manager

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

There are definitely scenarios where NI SystemLink will be useful but just didn't work out well for us. I needed to be able to replace an EXE file on a computer with a new EXE to do the upgrades but I was not able to do that through SystemLink. You had to work with packages in order to perform this and I didn't want to revamp my distribution plan. We also didn't need to do any asset management or calibration documentation through SystemLink. I was excited about being able to view data from the test stations through a browser but our engineers need historical data available and everything resets to a live view when you click back to the UI.

In our specific use case, SUSE Manager is extremely useful. We're having a large landscape that is divided into intake, development, quality and production with a couple of different SUSE flavours that need to be automatically rolled out, configured, patched and maintained, everything from up to date repositories that are cloned on a daily basis straight from SUSE.

• 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.

• Setup
• User Interface
• LabVIEW Integration

Incentivized

• Manages patch levels for most Linux OS by: date, group, cloud or custom channels
• Uses a lite version of Salt to run commands or scripts on any numbers of servers at once.
• Allows the joining of groups inside SUSE Manager to quickly access or work with servers so grouped.

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

• Licensing
• Not able to see data from all test stations on one UI
• Lack of data history

• The cloning of patches when using the content lifecycle module in a multi-environment landscape with many SLES flavours is a bit cumbersome.
• More premade saltstate for default applications are always nice to have.
• Upgrading SUMA could be easier, especially when a Postgres upgrade is also required.

I am expanding the use of SUSE Manager throughout our organization and can't imagine going back to the "wild wild west" we had before.

The gui is extremely user friendly. The installation and configuration does have a learning curve, it takes a while to set everything up. But once you're passed this initial learning curve, everything is very intuitive. If you want extra automation, there's an api (eventough i personally find the documentation of the api could be ordered better). I gave this product a 9 because of the initial learning curve and the api documentation, but for the rest it suits my needs perfectly.

SUSE Manager provided a top-tier support person on site to us for two days to help integration. We did all the standard stuff they help with before he arrived. We were able to use him to get all the tricky stuff identified and solved in the short time we had. Had they sent us a lower-tier guy, it would have been a waste. I was impressed they sent such knowledgeable person.

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.

The other competitors also have a good platform and service, but we went with SUSE due to cost. The price was best and we needed to keep under a certain budget. The functionality was perfect for what we needed so we took the step forward. This allows us to manage our Linux environment within the manager and update or deploy specific tasks to each as needed.

• 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.

Incentivized

• Availability to monitor multiple test stations remotely
• Was quick to integrate into existing LabVIEW codebase
• Ultimately did not justify the licensing cost for the benefit

Incentivized

• Manages patch levels for most Linux OS by: date, group, cloud or custom channels
• Make it easy to audit our own infrastructure.
• Allows the joining of groups inside SUSE Manager to quickly access or work with servers so grouped.
• 24/7 support team.
• Automatic deployment.
