MuhammadAzhar Khan - PeerSpot reviewer
Senior DevOps Engineer at Alibaba Group
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
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.

Quotes from Members

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

Pros

"The recommendation feature is really good."
"I strongly recommend using Trusted Advisor due to its role in cybersecurity, providing cost-effective solutions compared to external companies."
"The Security Advisor is the most valuable feature. It instantly informs you about any system misconfigurations, and the best part is, it's completely free."
"The key features include security recommendations, cost optimization, and various packages to choose from, depending on the size of the company."
"Trusted Advisor has helped our organisation gain insights into best practices across a number of important domains for us, and it has helped me maintain a holistic view of our AWS platform and guided me to improve areas needing it."
"I would give it a ten out of ten."
"AWS Trusted Advisor is a tool that we can use to optimize the AWS infrastructure cost."
"The cost optimization and security-related fixes in the AWS Trusted Advisor have been great."
"OpenNebula freed my customer from doing the maintenance operations of the servers because now that can be done by his clients."
"OpenNebula is lightweight, stable, and easy to customize."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
"It is quite easy to deploy."
"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."
"It's easy to integrate OpenNebula with our IT systems."
"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."
 

Cons

"Maybe adding more security rules would be great."
"I'd like the solution to support clouds beyond AWS."
"Cost is a significant factor that needs improvement. Reducing the cost would make it more beneficial for all users."
"However, the integration between Trusted Advisor and Security Hub occasionally confuses as there are many overlapping AWS services and the same finding can be duplicated."
"The tenancy must be free for all metrics."
"Maybe if Trusted Advisor could also help us with IP address issues and the status of our VPCs, it would be beneficial."
"Whenever they suggest anything or any changes in the environment, we cannot click and simply implement those changes."
"The integration between Trusted Advisor and Security Hub sometimes lacks, and I need a way to ensure things come through there."
"Template management also needs improvement in OpenNebula because it's inferior right now."
"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."
"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."
"The protocol for clusterization is rough and doesn't work well."
"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."
"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."
 

Pricing and Cost Advice

"Trusted Advisor offers various packages, with the most comprehensive costing $15,000 per month."
"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."
"VRA is very expensive but OpenNebula is free."
"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."
