Featured Reviews

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

"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."
"The cost optimization and security-related fixes in AWS Trusted Advisor have been great."
"Trusted Advisor offers features that provide inside information for the entire account, including identifying security gaps and offering cost optimization insights."
"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 cost optimization and security-related fixes in the AWS Trusted Advisor have been great."
"The cost optimization features are valuable."
"It is very stable."
"AWS Trusted Advisor is a tool that we can use to optimize the AWS infrastructure cost."
"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."
"OpenNebula has given us tremendous knowledge about cloud computing and about Cloud Management platforms, commonly known as CMP."
"For our use case, we found the solution to be the best fit when dealing with infrastructure services."
"The live migration feature has been great and is something we use very often."
"OpenNebula has very good integration with SAP Storage."
"What's best about OpenNebula that people like is that it's easy to deploy. It's also easy to manage. It's interesting because people choose OpenNebula over other solutions because of the ease of management."
"It makes maintenance very easy and stress-free for our teams."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
 

Cons

"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."
"Maybe if Trusted Advisor could also help us with IP address issues and the status of our VPCs, it would be beneficial."
"Cost is a significant factor that needs improvement. Reducing the cost would make it more beneficial for all users."
"Trusted Advisor currently scans the whole system, including development, staging, and QA environments, which increases costs."
"Maybe adding more security rules would be great."
"The integration between Trusted Advisor and Security Hub sometimes lacks, and I need a way to ensure things come through there."
"The tenancy must be free for all metrics."
"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."
"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."
"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."
"They should add more features like object storage."
"There are no payment gateways in OpenNebula."
"Template management also needs improvement in OpenNebula because it's inferior right now."
"Hosting platforms are limited so the deployment process needs improvement."
 

Pricing and Cost Advice

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