Cybersecurity tools have enabled comprehensive infrastructure monitoring and alerting

We have been using Amazon Inspector and Amazon Trusted Advisor for monitoring. These tools are especially useful for preventing cyberattacks on our systems. Trusted Advisor scans the complete infrastructure, providing a consolidated view of our account's systems. We use CloudWatch with Trusted…

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

"It is very stable."

"The cost optimization features are valuable."

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

"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."

"AWS Trusted Advisor is a tool that we can use to optimize the AWS infrastructure cost."

"I strongly recommend using Trusted Advisor due to its role in cybersecurity, providing cost-effective solutions compared to external companies."

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

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

More AWS Trusted Advisor pros

"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."

"With a single click, we could set things up and initiate them."

"The solution provides templates for configurations that can easily be exchanged to VMs."

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

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

"OpenNebula is lightweight, stable, and easy to customize."

"I also like the ability to build custom functions. I can define a function where I have two types of views and configure the dependencies. The virtual data centers concept allows me to define users. If a user wants to join certain kinds of machines, the host and the other user won't see them. It gives me the flexibility to define multiple views and data centers in one place."

"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."

More OpenNebula pros

Cons

"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."

"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."

"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."

More AWS Trusted Advisor cons

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

"The protocol for clusterization is rough and doesn't work well."

"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 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."

"Hosting platforms are limited so the deployment process needs improvement."

"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."

"The storage feature that they have is a bit confusing."

More OpenNebula cons

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."

"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."

"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."
