IBM DevOps Code ClearCase vs. Rackspace OpenStack

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

Need to get an application up and running, then I would say the open stack is a great place to test it out. Why spend time setting things up when you can let them do it for you? Many people also have experience with using Rackspace in some capacity so its an easier learning curve for many people.

• 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.

• Quick uptime
• Simple Signup
• Lots of options on what you need
• Rackspace is a known company (not some unknown startup)

Incentivized

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

• Support does not seem to be what it use to be, use to be a solid 10 when dealing with them, now more like an 8
• Pricing can be tricky to figure out
• For some people too many options.

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.

I looked into going with Amazon EC2, was very comparable in pricing, services, options, etc. and a bit cheaper too. Why I did not go with Amazon mainly has to do with knowing Rackspace and being familiar with them. It was easier for me to use a Rackspace product then go with Amazon Elastic Compute Cloud

• 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

• Quick setup allowed me to work on the application not setup of where it was going to run
• Expand ability with a few clicks was a great help, no worrying about if I needed more "power", few clicks and I had it.
• Tech support is hit or miss so that can be problematic and that was cause for concern and took time away from development
