IBM DevOps Code ClearCase vs. VMware Cloud Foundation vs. Yarn

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

It is best suited for an on-premise cloud solution where customer can shift their entire production environment. Also, the customer has a preference for a Homogenous Infrastructure Environment where budget is not a challenge. It is not at all suited for a Heterogenous Environment, e.g., a Public cloud where integration becomes a huge issue, also in SMB sections where budget is challenging.

There is really no real reason why not to use Yarn today. It's much faster than npm, and you will need a dependency management system anyway. The only thing that might be missing is the fact that it doesn't come natively with NodeJS, and you have to install it yourself. I'd like to see the NodeJS ecosystem include Yarn by default.

• 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.

• Cloud enabled Solution.
• Support Container based Apps.
• Cost efficient.
• Supports both Public and Private Environments.

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

• The Deployment is complex.
• Recommended Number of Physical Nodes is three or more; with less than 3 Nodes, it becomes difficult to install V-SAN.
• Need for better integration. If we go on the public cloud, it is a huge challenge while integrate with an open source platform.
• Cost can be marginally reduced. SMB segments still prefer a separate license instead of VCF, or they postpone their purchase plans.

• Rarely, some server connection error appear, while npm works alright.
• Sometimes, deleting the whole vendor directory is the best solution to solve weird issues.
• You still might need npm to install Yarn.

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.

Although the public Cloud Model follows Opex Costing Model, it actually leads to very high costs also, the infra model in my organization is not suited for a Public Cloud Model. Hence We decided on an On-Premise Model, and the best suited was VMware Cloud Foundation, which is a complete Software-Defined Scale-Out Architecture. I also prefer a Homogenous environment; i.e, support and services from a Single OEM, so that I Can get faster resolutions to my tickets raised.

Compared to npm, Yarn is a clear winner here. npm does not look to be getting any improvements recently. And it's much much slower to run when installing project dependencies. This has a clear impact on the developer productivity but also makes deployments slower. So Yarn is still a much superior choice.

• 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.

• My organization has a size of 1300+ employees, using multiple applications and an exchange mail server that is hosted on On-Premise Cloud, hence scalability has not been a challenge.
• Having hosted my Production environment and Mail exchange Server on VCF, there has been optimum resource utilization with very little scope downtime. Hence have been able to save a lot of funds on Hardware resources.
• Due to the size of my organization and due the data load, I have been able to save on Resource Utilization and Organization Funds

• Deployments happen much faster.
• Building and testing our apps is much more streamlined and efficient.
• Makes it easier to write reusable code.
