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.

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

"OpenNebula has very good integration with SAP Storage, is easy to use, has a good UI, and is very scalable."
"For our use case, we found the solution to be the best fit when dealing with infrastructure services."
"With a single click, we could set things up and initiate them."
"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."
"The most valuable feature of OpenNebula is that it scales very well."
"It makes maintenance very easy and stress-free for our teams."
"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."
"It's easy to integrate OpenNebula with our IT systems."
"The product has made it possible to reduce the size of the performance team and still be able to correctly monitor all the databases and fix issues quickly, resulting in fewer downtimes."
"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."
"The real-time threat detection has been the most valuable feature."
"It is easier to manage your Oracle Database backups and create email alerts regarding the status of your backups (Succeeded or Failed)."
"OEM is invaluable in many ways, other products can replace bits of it - but the product should be used as a single point from which to view as much of your enterprise as possible."
"​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.​"
"The dashboard and reporting help us to do preventative AI and analytics to detect performance bottlenecks."
"One of the clearest examples is the agility of discovering processes/sessions that are burdening the database environment. With this agility, the DBA can more quickly verify this type of problem, in addition to checking locked sessions and not having to do several searches in views and tables of the data dictionary. The tool already does this for you in an agile way."
 

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."
"Template management also needs improvement in OpenNebula because it's inferior right now."
"Hosting platforms are limited so the deployment process needs improvement."
"The front-facing API can be improved to support lots of requests when the platform is huge with lots of virtual resources."
"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."
"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."
"Hosting platforms are limited so the deployment process needs improvement."
"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."
"You cannot use Enterprise Manager as replacement for a WebLogic console."
"What it does, it does well, but it's so complex."
"There is a lack from the point of view of monitoring on the system. The performance of the system and its resources are things that I think can be improved. There needs to be real-time monitoring available on the solution."
"The on-premises installation is complex. It should be easier, especially for deploying agents that are running on a Windows machine that is running Oracle databases."
"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."
"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."
"The initial setup depends on your experience. For example, for people who are doing it for the first time, it's probably difficult."
"Oracle Enterprise Manager Cloud Control manages the monitoring and the graphs. Other tools complement the base monitoring. Zabbix is efficient with space pressure."
 

Pricing and Cost Advice

"OpenNebula gives good value for money."
"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."
"We use the Community Edition, rather than the Enterprise Edition."
"VRA is very expensive but OpenNebula is free."
"The solution is open source so is free."
"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 costs are largely too high."
"Oracle Enterprise Manager Cloud Control is a little expensive."
"I personally feel that the tool can be considered to be a little bit on the expensive side."
"One has to pay for the enterprise version."
"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."
"The solution's pricing is fine."
"it's neither expensive nor cheap."
"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."
