IBM DevOps Code ClearCase vs. wasmCloud

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

If you want to start pivoting your legacy code into a serverless paradigm this is the platform to target. If you want to start moving away from walled gardens and back into a space where code isn't centralized, costs can be offset by utilizing customer or edge hardware this is the platform to focus on. If you want a model that will scale well past many of the existing serverless frameworks, that won't get caught up in the security weaknesses of current paradigms this is what you need to invest in. If you want modern code to interact with legacy code in a safe way that doesn't expose vulnerabilities you can't patch against wasmCloud is awesome. If you want to write simple code that can jump from cloud to cloud to the user or edge node check it out!

• 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.

• Host density of workloads
• Streamlined security approach to writing code and reducing bloat
• Interoperability of modules written in different languages

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

• Simplified open-source model for on-boarding devs, i.e. bare host no elixir/GUI
• Home-labbers guide to wasmCloud
• Spark more community involvement for capability providers

wasmCloud is still in the early stages of development but the product is rapidly evolving and stabilizing and I feel it will be a preferred way of deploying and managing remote, distributed applications in the future.

The core team is extremely responsive in their provided channels. From slack to github issues, there is never a long wait for feedback or guidance.

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 team is incredibly helpful and informative about the product - I have not needed to use their professional services thus far.

• 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.

• WasmCloud has massively simplified the required ops expertise needed to run modern software.
