KS
Dev Ops Engineer at a construction company with 11-50 employees
Cost governance has improved and cost visibility now drives daily compliant optimization
CloudCheckr is an excellent tool overall. The feature that stands out is how it enables cost savings and efficiency. The cost visibility and reporting are really valuable, and the dashboard is informative and enables good decision-making. The actionable recommendations are beneficial, such as the auto-generated suggestions for optimization. The built-in security and compliance checks, along with scheduled reports, save a lot of manual effort and keep both engineering and finance teams aligned. CloudCheckr has been great and has helped solve problems by ensuring proper compliance. It does not just show data; it highlights actionable items for cost savings, security improvements, and compliance gaps. Scheduled reports are received on a regular basis according to defined schedules, providing more insights that can be shared with leadership and finance teams to ensure alignment. This results in a better picture where everyone is aligned and focused on growth while effectively and efficiently using financial resources. CloudCheckr has enabled an average cost saving of approximately 25% from the last year, and this occurred while also increasing the scale of production. It has significantly reduced manual efforts that would otherwise be spent manually checking costs, tracking where spending is occurring, and verifying whether everything is properly optimized.
FOURES Jean-Philippe - PeerSpot reviewer
Products Manager at a tech services company with 501-1,000 employees
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

"CloudCheckr has impacted my organization positively by making things easier and saving time, approximately three hours a week."
"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 solution is mostly stable."
"The initial setup is straightforward."
"The recommendation section is pretty helpful."
"It's one of the leading players for cloud optimization. It's hard to find anything better."
"CloudCheckr has enabled an average cost saving of approximately 25% from the last year, and this occurred while also increasing the scale of production."
"The most valuable feature of CloudCheckr CMx High Security is granular reporting. Additionally, the user interface is easy to use."
"It is quite easy to deploy."
"For the entire data center, as a private cloud, I believe that user management, expert management, and the virtual data center is completely magic for the users."
"OpenNebula is lightweight, stable, and easy to customize."
"The solution provides templates for configurations that can easily be exchanged to VMs."
"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 service feature appeals most to us, thus it is the most valuable."
"The most valuable feature of OpenNebula is that it scales very well."
"It makes maintenance very easy and stress-free for our teams."
 

Cons

"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."
"Many features still need to be implemented in this tool."
"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."
"Self-healing could be a bit smoother and a bit cleaner, easier to access and more functional. That would help."
"The reporting and analytic capabilities are very limited."
"The solution must improve its user interface."
"Some aspects could be made more customizable, such as the dashboard and UI."
"The solution needs to work better with larger capacities of data."
"The UI, monitoring, and alerting could benefit from further improvements."
"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."
"Most of the competitors are offering some sort of billing software to transform their installation to work as a small-sized public cloud, but those offerings from OpenNebula are still missing."
"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."
"The protocol for clusterization is rough and doesn't work well."
"The storage feature that they have is a bit confusing."
"Hosting platforms are limited so the deployment process needs improvement."
"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."
 

Pricing and Cost Advice

"The solution is reasonably priced."
"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 cost is on par with other providers."
"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."
"VRA is very expensive but OpenNebula is free."
"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."
