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.

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.

Pros

"The key features include security recommendations, cost optimization, and various packages to choose from, depending on the size of the company."

"The cost optimization and security-related fixes in the AWS Trusted Advisor have been great."

"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."

"Trusted Advisor offers features that provide inside information for the entire account, including identifying security gaps and offering cost optimization insights."

"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."

"I would give it a ten out of ten."

More AWS Trusted Advisor pros

"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."

"OpenNebula has very good integration with SAP Storage."

"The live migration feature has been great and is something we use very often."

"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."

"It's easy to integrate OpenNebula with our IT systems."

"The most valuable feature of OpenNebula is that it scales very well."

"It has enabled us to decrease the optics by around 55 to 60%."

"It makes maintenance very easy and stress-free for our teams."

More OpenNebula pros

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."

"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."

"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."

"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."

"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."

More AWS Trusted Advisor cons

"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."

"They should add more features like object storage."

"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."

"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."

"The front-facing API can be improved to support lots of requests when the platform is huge with lots of virtual resources."

"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."

"They should add more features like object storage."

More OpenNebula cons

Pricing and Cost Advice

"Trusted Advisor offers various packages, with the most comprehensive costing $15,000 per month."

"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."

"OpenNebula gives good value for money."

"The solution is open source so is free."

"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."
