IBM DevOps Code ClearCase vs. OpenText AccuRev 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

Very slow and not intuitive; it would be my last choice for version control systems.The UI is a little confusing at times and seems a little outdated. It needs a lot of improvement. It is suited for small projects and fewer number of projects. But if there are huge projects and many projects to be maintained in a portfolio, its a little hard to manage.

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.

Incentivized

• One place for most recent code with history, avoid any conflict/confusion among other team/members.
• Stream/Workflow approach to control approval process betwen all the teams, which I couldn't find in other version control tools I worked.
• Bundle our code in a small group (called, Issues in Accurev) to differentiate between different projects.

Incentivized

• 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.

Incentivized

• Ability to zoom in/out for stream-view. We currently have many streams/substreams and unable to view the entire workflow. Zooming in/out would benefit.
• Being a designer, I use Adobe Flash and SWF files. When updating the SWF files, Accurev does not see these files as being changed and you will be unable to promote. In order to push changes, you must totally rename the SWF file.

Incentivized

• 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.

Incentivized

We will renew because it is part of our build process.

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.

In my view, accurev ranks very low compared to other tools I have used. Microsoft TFS is the best in the industry as of today as it's a complete ALM solution. It does code version, bug tracking, user story documentation, and has easy integration with other external tools supporting many languages. So I would definitely recommend TFS to anyone.

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

Incentivized

• 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

• Better team coordination.
• Avoid confusion by having one place for all documentation and code.
• Better project management by having different work streams.

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
