AB
CTO at Encha
A highly scalable solution that gives good value for money, but it does not have payment gateways
OpenNebula's templates are weak, and it could do something to make template creation a lot easier to use. The solution has a template for every single VM you create, which is not clever. You should be able to use a template for many different virtual machines. There are no payment gateways in OpenNebula.
SC
technical Manager at DBA Expert Consulting
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 most valuable feature of OpenNebula is that it scales very well."
"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."
"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."
"OpenNebula has given us tremendous knowledge about cloud computing and about Cloud Management platforms, commonly known as CMP."
"I'll definitely recommend OpenNebula because it's an open-source solution that's effortless to set up, and the total cost of ownership is low."
"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 service feature appeals most to us, thus it is the most valuable."
"If you're using Oracle products, you should definitely use Oracle Enterprise Manager because it is central to product management."
"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."
"The dashboard and reporting help us to do preventative AI and analytics to detect performance bottlenecks."
"The tool is mainly for monitoring databases, especially focusing on performance. It supports various databases, including Oracle, allowing daily activity monitoring. The solution enables displaying performance metrics, providing continuous tracking. It also offers management capabilities for connected databases, featuring graphical performance graphs. Users can perform tasks like killing sessions and controlling database elements. Additionally, it allows viewing tables, SAN disks, and other database components."
"Oracle Enterprise Manager Cloud Control has been really useful for our organisation."
"Of course, that you can manage and create the backup strategies from a central environment for all your environments, so you don’t have to do so on each database. You can set up the policy you want for each database, but you do it from a central environment."
"Another feature is the Resource Manager, where we can manage the consumption of resources of certain queries, separately in resource groups. Depending on the characteristics of the query, queries can be placed in groups that consume less database and hardware resources."
"The most valuable feature of Oracle EMCC is its flexibility to manage various industries, projects, and tasks."
 

Cons

"They should add more features like object storage."
"Template management also needs improvement in OpenNebula because it's inferior right now."
"The storage feature that they have is a bit confusing."
"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."
"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."
"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."
"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."
"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 product is good for monitoring all databases, but in some cases it's not easy to maintain."
"We did encounter some stability issues but many of them were fixed."
"The product does have room for improvement in patch management."
"Oracle Enterprise Manager Cloud Control needs to improve its GUI."
"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. It's very complex. Linux based machines aren't so complicated but it's complex for Windows."
"​Oracle Data Guard monitoring: There are no alerts for redo log transport failure.​"
"Sometimes the alerts are coming a bit late, for example, an alert for the CPU. It depends on the threshold that you have, how long you want to check the CPU of the machine. I got some faulty alerts with Data Guard. I had stopped a synchronization for maintenance and then I re-synchronized Oracle Data Guard. It took some time to appear in Enterprise Manager and send me the right notification that Data Guard was up and running and synchronizing. I realized this because I went directly into the database to check the status of Data Guard, and it was telling me that it was running okay. But in Enterprise Manager, it needed some more time to update the interface."
"It's crucial to promptly resolve agent-related issues to ensure continuous and accurate monitoring of database features within the Oracle Enterprise Manager."
 

Pricing and Cost Advice

"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."
"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."
"Our customer uses Oracle Universal Credits to pay for their license on an annual basis. The price is definitely affordable."
"it's neither expensive nor cheap."
"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 licensing costs are largely too high."
"The solution's pricing is fine."
"One has to pay for the enterprise version."
"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."
