OpenText Dimensions CM vs. OVH Dedicated Servers

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

I think the only reason not to look at OVH Dedicated Servers is if you need something with higher resilience. It's important to remember that these are a single physical server and thus have the same risks of outage as if you deploy a single physical server anywhere else. Most VPS solutions (whether OVH or elsewhere) have all the failover and HA abstracted from you and so offer less administrative overhead. However in terms of the amount of compute, storage and RAM you can get for your dollar, you can't beat the value proposition of OVH, and coupled with that they will repair the hardware if it fails, your task is simply to ensure you've take appropriate backup steps, and understand your RTO and RPO and architect accordingly. If you can withstand a period of downtime, then a single dedicated server will go a long way!

• 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.

• 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.

• Security options are pretty basic, we must use SOAR software alongside to secure the servers.

Everything has been thought of - from the initial password secure portal, through to day to day management, you can do everything from the console easily. Remote KVM is on hand for those awful moments (if you have them - and we all have) where the server won't boot for some reason

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

OVH Dedicated Servers are a different product so a direct comparison is difficult. In simple terms, both provide compute, memory and storage. However the EC2 instances offer significantly more in the way of resiliency in the event of a single hardware failure. However this comes at a price, and there is no way you could get 18TB of RAID5 style storage on HDD from a Public Cloud provider for the price of an OVH Dedicated Server
