HashiCorp Vagrant vs. OpenText Dimensions CM

If you're writing software, particularly software that depends on other services (web servers or databases for example) then Vagrant is great. I know some people skip Vagrant and just set up virtual machines on their own, but I've found that Vagrant streamlines the process nicely and makes it easy to update or swap out versions. If you're a web developer (which I am) it's amazing. I can have several boxes configured for my different projects and I just spin them up or down based on what I'm working on. One scenario where this might not be ideal is if you're running Vagrant on a computer that has limited resources. Since you're running a virtual machine with its own operating system and such you'll want a host computer with enough RAM, hard drive space and CPU to run the virtual machine properly without killing the performance of the host. The virtual disks can also take up a lot of space if you're not careful so if you have many virtual machines provisioned and don't clean up the old ones that you're not using, you may find that your hard drive is full. Each of my Linux servers take up about 10GB of disk space.

Serena CM is well suited to highly controlled, audited, and process driven environments. It will allow strict segregation of duties, and change traceability. If implemented correctly it will help you quickly build trusts with your auditors. It is also well suited to environments that require constant branching and merging. Due to the complexity of the product and learning curve for your development and operations team it may be overkill in a small shop with loose rules

• Easy to create machines with different OS's, list of them can be found from Vagrant's website with configuration details.
• Flexible configuration, user can determine what software will be pre-installed to machine. Saves time because it doesn't need to be done manually every time.
• Easily manage full environments, not just single machines, with single command.

• Code Promotion: Dimensions CM allows supervisors to control changes to code, in that they delegate requests to developers, and act as a gatekeeper prior to promoting to the next environment. This functionality is configurable so you can set up a workflow that best fits the structure and requirements of your own company.
• Code Repository for changes and versioning: Code can be checked out by item or by synchronizing folders. Code revisions can be compared against other revisions or work files. Item histories show which developers made which modifications, and which supervisor and operations personnel were involved in assigning the request and promoting the code to each environment. Additionally a pedigree will show a stream diagram which graphically displays branches and merges.
• Deployment: Serena Change Management offers help automating deployment including integrations with SVN and Jenkins. Its newer versions also have a powerful graphical deployment automation tool (Serena Deployment Automation- SDA). It comes with a certain amount of licenses built-in. If you have a many nodes to deploy to there will be separate licensing costs for that.

• Learning curve is steep - It can be challenging for someone to set up initially. After some coaching, the basics come pretty quickly though.
• Relies on external Virtual Machine applications - It would be great if Vagrant itself could run the virtual machine instead of leaning on other virtualization software. This is a small detail, but would make setup simple.
• Better support for running

• The only major negative that I have encountered with Serena CM product is that the very power and flexibility of the tool means there is a risk that you will make a mess of things. In other words it gives you plenty of rope to tangle yourself with. I recommend careful, well thought out deployments implementing the built in roles and workflows that can be turned on and configured, using a consistent methodology.
• My experience with the Serena help desk support has not been impressive. Though reasonably polite and diligent, the technicians were well trained, and often gave bad advise and terrible scripts. On several occasions I had to rewrite scripts they have me; if I had run them as provided they would have caused even more difficulties than the problem I was trying to solve. I speak of the support in the past tense because I conditioned myself not to call them, it was usually just easier to solve nay problems my self. They do have a good account management team though, and for any major issues you can go thru them.

Vagrant is fast, versatile and does exactly what we need it to do: spin up virtual servers for local development fast and without trouble.

A GUI would be nice for entry level users.

Docker has a few advantages, especially with the disk size bloat brought on by Vagrant's hosting an entire OS and project in a VM. It relies on native tools, however, and may not support every software. Vagrant provides uniformity, efficiency and repeatability within team work and for deployment and testing.

Serena CM is superior to Microsoft Team Foundation Server (TFS) in overall functionality, but does not have very good native integration with Microsoft. Therefore in a Microsoft centric shop with no audit needs ,TFS would be better. Otherwise I would choose Serena CM

• Saved lots of time by being able to set up a local env quickly
• Occasionally made troubleshooting bugs harder than it would have been using native Linux
• Clients had issues setting it up, which may have provided us some security in keeping their business

• Serena has facilitated our annual completion of various audit and technology control certifications. These certifications make a huge difference to our company's reputation and bottom line.
• There has been no negative impact on our company.
