Sr PreSales Cloud Architect at a outsourcing company with 10,001+ employees

Centralized cloud costs have boosted savings while reporting and user experience still need work

The best features CloudCheckr offers include out-of-the-box security and compliance check features that provide over 35 different types of compliance checks at no cost, best practice checks, and alerts. Another valuable feature is the multi-cloud overview, providing unified reporting across AWS and Azure while allowing us to create different types of dashboards based on who logs into the platform. Additionally, from an MSP standpoint, there is good ease of deployment, especially the billing and chargeback functionality for a reseller or managed services provider. CloudCheckr has positively impacted my organization by helping us manage multiple customers and tens of thousands of resources while retaining performance and visibility due to its multi-cloud support. We do not have to worry about jumping from one platform to another, and the better MSP support is beneficial from a billing and chargeback automation standpoint. The integration in compliance helps identify missing areas within our customer environments and improves them. On average, it has helped us provide approximately 15 to 20% savings through right-sizing or idle resource elimination. These are some of the immediate cost savings our customers have experienced after implementing recommendations from the tool.

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 enabled an average cost saving of approximately 25% from the last year, and this occurred while also increasing the scale of production."

"The solution is scalable for our purposes."

"The initial setup is straightforward."

"The solution is mostly stable."

"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."

"I have seen a return on investment of 100%, with significant cost avoidance and measurable savings within the first few months of deployment."

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

"The recommendation section is pretty helpful."

More CloudCheckr pros

"It is quite easy to deploy."

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

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

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

"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."

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

"The ability to use it almost like a public cloud for an organization is a big asset, as it will create a value proposition and can control costs in a great way."

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

More OpenNebula pros

Cons

"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."

"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."

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

"I was not satisfied with the customer support from CloudCheckr."

"Some aspects could be made more customizable, such as the dashboard and UI."

More CloudCheckr cons

"The web interface could be better. It's not very difficult to use, but there's room for enhancement."

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

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

"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."

"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 should add more features like object storage."

More OpenNebula cons

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."

"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."

"VRA is very expensive but OpenNebula is free."

"OpenNebula gives good value for money."

"The solution is open source so 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."
