The solution reduced our operational expenditures and is able to identify points before we even noticed them

The management interface seems to be designed for high-resolution screens. Somebody with a smaller-resolution screen might not like the web interface. I run a 4K monitor on it, so everything fits on the screen. With a lower resolution like 1080, you need to scroll a lot. Everything is in smaller windows. It doesn't seem to be designed for smaller screens. When I change the resolution to 1080, I only see half of what I would on my big 4K monitor. It would be annoying to have to scroll to see the flow chart. They have a flow chart that goes top to bottom like a tree. On a lower resolution, it might be nice if that scrolls horizontally because it's long, narrow, and tall. It's only three icons wide, but it's 15 icons tall. I think it would be helpful to have the ability to change that for a smaller screen and customize the widget.

Reliable, simple to manage, and offers great technical support

The support of VXLAN fits with our network management. Thanks to this we can propose mixed solutions using virtual resources on OpenNebula and bare metal servers hosted in our facilities linked to each other on the sale network. This use case is very useful when some applications need bare metal power (Kubernetes workers, huge databases, AI models computations, et cetera). The cluster management is very useful for splitting our different clusters (mutual vs dedicated). We can manage deployments and capacity planning without pain. The API is also really simple and it helped us to develop the Terraform provider to manage OpenNebula like any other cloud infrastructure.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Turbonomic gives us insight and assurance that we are meeting operational targets."

"Great product and we use it extensively, from setting up VMturbo to load balance our VM's across a cluster, implementing right sizing recommendations, policy rules, memory/storage and CPU trends and plans for future projections in order to determine how we can reduce our hardware and licensing footprints."

"We have seen a 30% performance improvement overall."

"Customer Service: Perfect, with attention to details on every open ticket, and Technical Support: Top notch effort put into each support request."

"We have easily saved tens of thousands of dollars over the last 2 years by enabling right-sizing and automated workload placement."

"My experience with Turbonomic has been exceptional, they've offered me a $25 gift card to write a review of their company but I'd gladly write them a review for free."

"Turbonomic is an excellent product as far as we are concerned for managing the pod sizes and determining the best sizing for those pods."

"We have really loved having VMTurbo."

More IBM Turbonomic pros

"I also like the ability to build custom functions. I can define a function where I have two types of views and configure the dependencies. The virtual data centers concept allows me to define users. If a user wants to join certain kinds of machines, the host and the other user won't see them. It gives me the flexibility to define multiple views and data centers in one place."

"The solution provides templates for configurations that can easily be exchanged to VMs."

"It is quite easy to deploy."

"OpenNebula has given us tremendous knowledge about cloud computing and about Cloud Management platforms, commonly known as CMP."

"It's easy to integrate OpenNebula with our IT systems."

"OpenNebula freed my customer from doing the maintenance operations of the servers because now that can be done by his clients."

"I'll definitely recommend OpenNebula because it's an open-source solution that's effortless to set up, and the total cost of ownership is low."

"With a single click, we could set things up and initiate them."

More OpenNebula pros

Cons

"The interface could be a little cleaner and navigation a little easier."

"The way it handles updates needs to be improved."

"When trying to view a trend at 4+ day period, the trend lines tend to flatten out and move to a single data point a day."

"One issue I have is just not knowing how to get some information I believe is there."

"The graphical interface could be better."

"The arithmetic of optimizing the resources of VMs based on the workload. Some of workload are by a monthly basis. Need to consider the month-end or quarterly-end workload."

"Have plan data shared across user accounts within Turbonomic. Also more granular permissions."

"I like the detail I get in the old user interface and will miss some of that in the new interface when we perform our planned upgrade soon."

More IBM Turbonomic cons

"They have been saying for the past two and a half years that they would develop a feature to hot-add RAM and CPU, but it does not work."

"They should add more features like object storage."

"I would like to see OpenNebula add more integration with REST API. XML-RPC API is good, but it becomes a pain to form a resting output."

"The storage feature that they have is a bit confusing."

"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."

"The front-facing API can be improved to support lots of requests when the platform is huge with lots of virtual resources."

"An area for improvement in OpenNebula is the number of features it has. The solution doesn't have that many cloud features compared to other solutions. You'd say, "Okay, simplicity over a rich feature list?" Some say, "No, I need a big machine or a cloud interface for my customers to manage resources. I don't have to go and do it for them." Some people do it that way, and it works, but I'd like to improve the limited features in OpenNebula."

"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."

More OpenNebula cons

Pricing and Cost Advice

"The pricing is in line with the other solutions that we have. It's not a bargain software, nor is it overly expensive."

"When we have expanded our licensing, it has always been easy to make an ROI-based decision. So, it's reasonably priced. We would like to have it cheaper, but we get more benefit from it than we pay for it. At the end of the day, that's all you can hope for."

"It is an endpoint type license, which is fine. It is not overly expensive."

"Licensing is per socket, so load up on the cores rather than a lot of lower core CPUs."

"I'm not involved in any of the billing, but my understanding is that is fairly expensive."

"Everybody tells me the pricing is high. But the ROIs are great."

"In the last year, Turbonomic has reduced our cloud costs by $94,000."

"The product is fairly priced right now. Given its capabilities, it is excellently priced. We think that the product will become self-funding because we will be able to maximize our resources, which will help us from a capacity perspective. That should save us money in the long run."

More IBM Turbonomic pricing and cost advice

"VRA is very expensive but OpenNebula is free."

"We use the Community Edition, rather than the Enterprise Edition."

"The licensing for OpenNebula used to be free, but now it's no longer free. A customer contacted me asking to move to another provider because of the changes in the licensing terms for OpenNebula. I have no information on how much the OpenNebula license is because the customer pays for it, and I only do the integration."

"The solution is open source so is free."

"OpenNebula gives good value for money."

"OpenNebuoa has recently come up with a new subscription model that is economical and a lot of new customers are choosing this as it is an easy subscription model."
