Executive SummaryUpdated on Dec 17, 2024

Oracle Enterprise Manager Cloud Control and OpenNebula are contenders in the cloud management domain. Oracle holds the edge with its feature-rich offerings, while OpenNebula is favored for its simplicity and flexibility.

Features: Oracle Enterprise Manager Cloud Control is known for its comprehensive database management, real-time monitoring, and centralized administration. It supports various Oracle products, providing detailed insights into performance. OpenNebula stands out for its ease of use, stability, and customization. It effectively manages virtual machines across different hypervisors and offers an API for extended functionalities.

Room for Improvement: Oracle Enterprise Manager Cloud Control needs a simplified setup and better compatibility with non-Oracle systems. Enhanced documentation and integration with more environments are also required. OpenNebula benefits from improved documentation and API functionality. The addition of more cloud features would streamline deployments in diverse environments.

Ease of Deployment and Customer Service: Oracle Enterprise Manager Cloud Control provides extensive support, facilitating complex hybrid cloud deployments. Despite its robust technical resources, users desire quicker support responses. OpenNebula, mainly used in on-premises setups, is easy to implement with less support dependency, but responsiveness improvements could enhance user experience.

Pricing and ROI: Oracle Enterprise Manager Cloud Control is more costly, making it suitable for large enterprises within Oracle's ecosystem. OpenNebula offers a cheaper alternative through its open-source model, making it accessible for organizations aiming to reduce spending, with its free community and low-cost enterprise versions ensuring flexibility and functionality.

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

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

"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."

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

"It is quite easy to deploy."

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

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

"OpenNebula has very good integration with SAP Storage."

More OpenNebula pros

"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."

"You can create a system group (database, application, and web server), so you can monitor performance as a system."

"The capability to manage incidents, monitor agent statuses, and address performance issues is highly valuable."

"The report feature is very useful."

"With the last version I worked with, we can perform auto-configuration to resolve issues for the database, such as automatically adding space when a tablespace runs low."

"Oracle Enterprise Manager Cloud Control has an amazing GUI interface that does a lot of tasks with fewer steps rather than making it manual on the database or the operating system side."

"Compared to other monitoring products, the user interface is very clear. It sends clear notifications."

"Once this solution is configured, it will help administrators centralize their management of the environment."

More Oracle Enterprise Manager Cloud Control pros

Cons

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

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

"They should add more features like object storage."

"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."

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

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

"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."

"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."

More OpenNebula cons

"Oracle Data Guard monitoring: There are no alerts for redo log transport failure."

"The only negative thing about this product is that it doesn't support all environments or all applications."

"Another point that can be improved is the agent instability in the monitored hosts, because sometimes an agent has to be resynchronized to recapture the information."

"There is a lot of information required to deal with the vulnerabilities in the product on a timely basis, for which the documentation part is not available."

"Because this solution provides insight into all of the areas within the IT stack, it would benefit from enhancements in security."

"Oracle Enterprise Manager Cloud Control needs to improve its GUI."

"The response time of the solution's technical support team is too long and should be improved."

"Because all our banking infrastructure is based on Oracle, I’ve tried to register Enterprise Manager on the middleware level, let's say, WebLogic applications. But I cannot say that I can do all the administration from Enterprise Manager, that I can do from the WebLogic Admin Console. So, I think here it needs some improvement: Things that you can do on the WebLogic Admin Console, you should be able to do them on the Enterprise Manager, so you don’t have to log into the Admin Console."

Pricing and Cost Advice

"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."

"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."

"VRA is very expensive but OpenNebula is free."

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

"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."

"The solution's pricing is fine."

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

"it's neither expensive nor cheap."

"One has to pay for the enterprise version."

"The licensing costs are largely too high."

"The tool's pricing is competitive."

"Our customer uses Oracle Universal Credits to pay for their license on an annual basis. The price is definitely affordable."
