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 cost optimization and security-related fixes in the AWS Trusted Advisor have been great."
"The cost optimization features are valuable."
"AWS Trusted Advisor is a tool that we can use to optimize the AWS infrastructure cost."
"The recommendation feature is really good."
"The key features include security recommendations, cost optimization, and various packages to choose from, depending on the size of the company."
"Trusted Advisor scans the complete infrastructure within the account, providing a consolidated view of all services in use."
"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."
"It is very stable."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
"For our use case, we found the solution to be the best fit when dealing with infrastructure services."
"OpenNebula has given us tremendous knowledge about cloud computing and about Cloud Management platforms, commonly known as CMP."
"The most valuable feature of OpenNebula is that it scales very well."
"The live migration feature has been great and is something we use very often."
"The solution provides templates for configurations that can easily be exchanged to VMs."
"OpenNebula has very good integration with SAP Storage, is easy to use, has a good UI, and is very scalable."
"With a single click, we could set things up and initiate them."
 

Cons

"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."
"I'd like the solution to support clouds beyond AWS."
"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."
"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."
"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."
"The storage feature that they have is a bit confusing."
"Template management also needs improvement in OpenNebula because it's inferior right now."
"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."
"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."
"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."
"Hosting platforms are limited so the deployment process needs improvement."
"They should add more features like object storage."
"The protocol for clusterization is rough and doesn't work well."
 

Pricing and Cost Advice

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