Provides recommendations regarding how cost and consumption can be adjusted, but the reporting and analytic capabilities are very limited

We are not happy with the product’s reporting capabilities. We are planning to change the solution. The security compliance feature doesn’t give much data because CloudCheckr has done a majority of its development on AWS. The majority of our clients are on Microsoft Azure. There are a lot of features and information available for Amazon, but not for Azure. The tool wasn't meeting our expectations. The reporting and analytic capabilities are very limited. There's no ability to do scheduled email reports. The report could only be sent to a single email address. The tool was not very usable. We had multiple clients and tasks to work with.

Robust with great CLI tools and UI

I've found OpenNebula upgrades to be more complex than those of some of the competitors and the support to be mediocre. I would also like to see more and better ancillary tools related to OpenNebula, for example, more robust tools for backups, user support, etc. The support knows their software stack reasonably well. However, OpenNebula depends on so many open-source projects that they lack expertise. As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today.

Quotes from Members

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

Pros

"The solution is scalable for our purposes."

"The best feature I like about CloudCheckr CMx High Security is its simplicity. I love that it's not rocket science to use the solution. Even if you're not familiar with the cloud, you can easily figure out how to use CloudCheckr CMx High Security. You can use AWS, you can use Azure, and you can use GCP with the solution because the integration is quite simple. You can also use multi-cloud with it, and you could see the billing part. You'll have complete visibility into your cost which I love about the solution. I also love that data on any security issues and vulnerabilities are available on the go with CloudCheckr CMx High Security. You don't need to do anything different. Just run the scan and you'll have all these open findings in the tool, in terms of the priority level, so if it's critical, it will tell you, "It's critical," and you need to fix it right away."

"The recommendation section is pretty helpful."

"It's one of the leading players for cloud optimization. It's hard to find anything better."

"The solution is mostly stable."

"The most valuable feature of CloudCheckr CMx High Security is granular reporting. Additionally, the user interface is easy to use."

"The initial setup is straightforward."

"It will automatically suggest areas for optimization."

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

"OpenNebula has very good integration with SAP Storage."

"What's best about OpenNebula that people like is that it's easy to deploy. It's also easy to manage. It's interesting because people choose OpenNebula over other solutions because of the ease of management."

"The live migration feature has been great and is something we use very often."

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

"The most valuable feature of OpenNebula is that it scales very well."

"OpenNebula is lightweight, stable, and easy to customize."

"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."

Cons

"The reporting and analytic capabilities are very limited."

"The solution needs to work better with larger capacities of data."

"Self-healing could be a bit smoother and a bit cleaner, easier to access and more functional. That would help."

"Many features still need to be implemented in this tool."

"The performance of the tool really needs to be improved."

"The solution must improve its user interface."

"CloudCheckr CMx High Security is complex. There are a lot of menus, and if you do not know what you are looking for you can get lost. However, the interface is self-explanatory. It's easy to understand where to go to get what you want."

"What needs to be improved in CloudCheckr CMx High Security is integration. All the clouds are going quite fast, for example, all the cloud providers: Microsoft, Google, etc. CloudCheckr CMx High Security is good with AWS, no doubt about it, but with Azure and Google Cloud, I find that the solution is slow in that direction. If the vendor planned for CloudCheckr CMx High Security to be automated just for AWS, then it does make sense. If not, if the vendor is also targeting good integration with Google and Microsoft, then CloudCheckr CMx High Security integration needs improvement, in particular, it has to be faster. At the moment, its integration with Azure is not as good as its integration with AWS. With GCP, integration is nowhere."

"There are no payment gateways in OpenNebula."

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

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

"The UI, monitoring, and alerting could benefit from further improvements."

"The protocol for clusterization is rough and doesn't work well."

"It should have a simple REST API like most other tools. It's the industry standard format. An XML-RPC API gives you an XML document that you have to convert and then do something with that. REST API endpoint provides outputs in a JSON document. I would also like to see support for user data or heat templates, which OpenStack offers, but OpenNebula doesn't have this yet."

"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."

"Hosting platforms are limited so the deployment process needs improvement."

More OpenNebula cons

Pricing and Cost Advice

"The cost is on par with other providers."

"A license is needed to use CloudCheckr CMx High Security, but because we are a managed service provider, the price of the license would vary. It depends on the type of cloud users we have, for example, it would be some type of percentage or monthly billing, etc."

"The solution is reasonably priced."

"VRA is very expensive but OpenNebula is free."

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

"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."

"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."
