SUSE Harvester vs. VMware vSOM (discontinued)

It's great for provisioning any kind of virtual servers, but for now, we use it to provision only servers for Rancher managed Kubernetes clusters. But we are considering to provision also virtual servers for all kinds of needs on SUSE Harvester in the near future, as it's getting more and more mature with every release.

Vsphere Operation Management is suitable for automating the process of bringing up an alternate data center in case of a disaster. It also is a great way for testing your readiness of disaster. You have the ability to bring up a server in a "bubble" for testing. This way you can show your admins how the failover process will work.

Incentivized

• Fast to deploy new virtual machines
• It's easy to use
• Stable and ready for production
• Free and open source
• Has a strong community

• The best thing about VSOM is that it's built into VCenter so you only have one point of administration
• VSOM does a great job of making applications intuitive
• Re-IPing virtual machines are a must and VSOM does a great job of making this a simple process

Incentivized

• It takes expertise to set up SUSE Harvester for production
• You need to get used to SUSE Harvester to be as "fluent" as in VMWare ESXi
• You need to well prepare for system upgrades

• The installation of VSOM is very tedious
• It uses an MS SQL database
• It should be able to adjust for hardware modifications in VCenter

We used ESXi for years and were happy with it. Then we implemented Rancher managed Kubernetes clusters with nodes provisioned on VMware ESXi. Later, when SUSE Harvester came out, we started to provision SUSE Rancher nodes on Harvester. Both VMware ESXi and SUSE Harvester are great products, and I think - we are keeping both, at least for now, when SUSE Harvester is a young project.

vSphere with Operations Management has a much better way of automating the re-IPing of servers so you can stand them up in a different environment or location. You do, however, need another way of replicating your servers to your DR site, VSOM will not do that. We used EMC Recover Point for replication.

Incentivized

• We can provision more virtual servers
• It's cheaper than competitor products (tbh - it's free, if you don't need support)
• It's easy to manage when you get used to it

• In the case of a disaster, the ROI would be substantial.
• The license for VSOM is pretty expensive initially.
• Support for VSOM is terrific.
