IBM DevOps Code ClearCase vs. Pointel Configuration Management Solution vs. Salt Project

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

SaltStack is a very well architected toolset and framework for reliably managing distributed systems' complexity at varied scale. If the diversity of kind or number of assets is low, or the dependencies are bounded and simple, it might be overkill. Realization that you need SaltStack might come in the form of other tools, scripts, or jobs whose code has become difficult, unreliable, or unmaintainable. Rather than a native from-scratch SaltStack design, be aware that SaltStack can be added on to tools like Docker or Chef and optionally factor those tools out or other tools into the mix.

• 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.

• Targeting is easy and yet extremely granular - I can target machines by name, role, operating system, init system, distro, regex, or any combination of the above.
• Abstraction of OS, package manager and package details is far advanced beyond any other CRM I have seen. The ability to set one configuration for a package across multiple distros, and have it apply correctly no matter the distrospecific naming convention or package installation procedure, is amazing.
• Abstraction of environments is similarly valuable - I can set a firewall rule to allow ssh from "management", and have that be defined as a specific IP range per dev, test, and prod.

Incentivized

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

Incentivized

• Managing network hardware should be more native and easy
• SaltStack should buffer jobs and, when a client returns, make sure it is executed proberly
• SaltStack should provide basic pillar and states structures to help get newbies started

We haven't had to spend a lot of time talking to support, and we've only had one issue, which, when dealing with other vendors is actually not that bad of an experience.

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.

We moved to SaltStack from Puppet about 3 years ago. Puppet just has too much of a learning curve and we inherited it from an old IT regime. We wanted something we could start fresh with. Our team has never looked back. SaltStack is so much easier for us to use and maintain.

• 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.

• We manage two complex highly available self-healing (all infrastructure and systems) environments using SaltStack. Only one person is needed to run SaltStack. That is a HUGE return on investment.
• Building tooling on top of SaltStack has allowed us to share administrative abilities by role - e.g. employee X can deploy software Y. No need to call a sysadmin and etc.
• Recovery from problems, or time to stand-up new systems is now counted in minutes (usually under eight) rather than hours. This is a strategic advantage for rolling out new services.
