Featured Reviews

MuhammadAzhar Khan - PeerSpot reviewer
Optimizes cloud strategies with security and cost insights
Trusted Advisor offers features that provide inside information for the entire account, including identifying security gaps and offering cost optimization insights. The key features include security recommendations, cost optimization, and various packages to choose from, depending on the size of the company. It is especially beneficial for larger companies, as the tool provides a comprehensive view of account security, open ports, buckets, and offers recommendations for protection.
FOURES Jean-Philippe - PeerSpot reviewer
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

"Trusted Advisor scans the complete infrastructure within the account, providing a consolidated view of all services in use."
"The cost optimization and security-related fixes in AWS Trusted Advisor have been great."
"The cost optimization features are valuable."
"I would give it a ten out of ten."
"I strongly recommend using Trusted Advisor due to its role in cybersecurity, providing cost-effective solutions compared to external companies."
"The recommendation feature is really good."
"Trusted Advisor offers features that provide inside information for the entire account, including identifying security gaps and offering cost optimization insights."
"The key features include security recommendations, cost optimization, and various packages to choose from, depending on the size of the company."
"The live migration feature has been great and is something we use very often."
"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."
"The solution provides templates for configurations that can easily be exchanged to VMs."
"It's easy to integrate OpenNebula with our IT systems."
"OpenNebula has very good integration with SAP Storage."
"It is quite easy to deploy."
 

Cons

"The integration between Trusted Advisor and Security Hub sometimes lacks, and I need a way to ensure things come through there."
"Trusted Advisor currently scans the whole system, including development, staging, and QA environments, which increases costs. It would be better if it could selectively scan only production systems."
"Cost is a significant factor that needs improvement."
"I'd like the solution to support clouds beyond AWS."
"Maybe adding more security rules would be great."
"For EC2 instances, we need to install the AWS CloudWatch agent to get the memory metric because we don't have a by-default memory utilization graph on cost optimization."
"Maybe if Trusted Advisor could also help us with IP address issues and the status of our VPCs, it would be beneficial."
"The tenancy must be free for all metrics."
"The storage feature that they have is a bit confusing."
"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."
"There are no payment gateways in OpenNebula."
"They should add more features like object storage."
"Hosting platforms are limited so the deployment process needs improvement."
"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."
"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."
 

Pricing and Cost Advice

"Trusted Advisor offers various packages, with the most comprehensive costing $15,000 per month."
"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."
"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 solution is open source so is free."
"We use the Community Edition, rather than the Enterprise Edition."
"VRA is very expensive but OpenNebula is free."
