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.

Extensive tool features support database monitoring, but support and pricing present challenges

I don't fully understand what improvements could be made in Oracle Enterprise Manager Cloud Control. To make it better, more features could be added, but it is already a very complete tool, especially if you know how to configure it properly, as you can use it to monitor other databases such as PostgreSQL and SQL Server in addition to Oracle.

Quotes from Members

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

Pros

"For our use case, we found the solution to be the best fit when dealing with infrastructure services."

"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."

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

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

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

"It has enabled us to decrease the optics by around 55 to 60%."

"The service feature appeals most to us, thus it is the most valuable."

"OpenNebula has very good integration with SAP Storage."

More OpenNebula pros

"Using Enterprise Manager, I was able to create user profiles for all the instances that have the same profile. Secondly, it's easier to manage performance, to automate the AWR reports to run every half an hour, or hour. Then, if you have a performance issue you just open the report and you can see what was running the last one hour, the SQL statements, or what was causing the performance issues."

"There are lot of features in this product that I like, among them are that RMAN backup jobs can be created, and that all the database instances can be monitored from one place."

"From a performance perspective, the management capabilities of the product are very valuable to its customers."

"The valuable feature is job scheduling. It manages the database's scheduling, history, and growth, helping monitor CPU and space usage across the entire data center. It provides a comprehensive view of operations."

"Oracle Enterprise Manager Cloud Control has improved our organization in many ways: Before implementing this solution, the patching was done manually; now we do the same task with patching management, and before, we used to monitor every server every day, but now we don't have to monitor it because we have an in-place solution and we get alerts so we can proactively monitor every server before a problem happens on it."

"EM Cloud Control gives me a good way to look at everything in one snapshot and to stay on top of daily monitoring."

"The solution provides very useful insights for application and database performance tuning. We were able to do away with guess work in determining where the bottlenecks were in application performance."

"SAP is a high-performance application, and we are able to use Oracle Enterprise Manager Cloud Control to monitor and prevent bottlenecks."

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."

"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."

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

"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."

"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."

"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."

"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."

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

More OpenNebula cons

"The product does have room for improvement in patch management."

"The product lacks in the area of database, making it an area where improvements are required."

"It's crucial to promptly resolve agent-related issues to ensure continuous and accurate monitoring of database features within the Oracle Enterprise Manager."

"While entering the database, there is some delay in viewing the data on the page called SQL monitoring, which reviews live statistics about the current and live queries on the database."

"You cannot use Enterprise Manager as replacement for a WebLogic console."

"One of the things that can be improved is the quality of results generated by BI Publisher. They are somewhat confusing when it comes to analysis."

"The installation steps are very complex and the documentation for them is very generic and does not make very clear the correct steps from the installation to the addition of the host and database."

"Sometimes the alerts are coming a bit late, for example, an alert for the CPU."

More Oracle Enterprise Manager Cloud Control cons

Pricing and Cost Advice

"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."

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

"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."

"VRA is very expensive but OpenNebula is free."

"We are using the free version. We are not using any licensed packages of Enterprise Manager, so I’m not quite sure how much each package is. As I understand it, there are different plug-ins that you need to buy for Enterprise Manager."

"I personally feel that the tool can be considered to be a little bit on the expensive side."

"The solution's pricing is fine."

"The tool's pricing is competitive."

"Oracle Enterprise Manager Cloud Control is a little expensive."

"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a six out of ten."

"Oracle Enterprise Manager Cloud Control is a pretty expensive solution but worth the money."

"One has to pay for the enterprise version."
