MuhammadAzhar Khan - PeerSpot reviewer
Unified security management ensures comprehensive compliance for account safety
Control Tower offers many valuable features for managing all account security. I can manage user security and user IAM, firewall, and other security-related tasks via Control Tower. The unified security management is a crucial aspect, and whenever an AWS organization is used, Control Tower is typically included to ensure comprehensive compliance fulfillment.
FOURES Jean-Philippe - PeerSpot reviewer
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

"AWS Control Tower helps companies save costs."
"With Control Tower, there are ready-to-use automated templates available, simplifying the implementation of a centralized management solution."
"It provides centralized solutions for all AWS accounts in one place, customized to meet the organization's specific needs."
"Security is the most valuable feature of Control Tower."
"The most significant benefit of Control Tower is its capability to align with our organization's standards."
"AWS Control Tower is a tool specifically designed for multi-account management. It offers the advantage of highly granular management."
"Compliance is the most valuable feature."
"Control Tower offers many valuable features for managing all account security."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
"The solution provides templates for configurations that can easily be exchanged to VMs."
"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."
"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 is lightweight, stable, and easy to customize."
"The most valuable feature of OpenNebula is that it scales very well."
"With a single click, we could set things up and initiate them."
"The service feature appeals most to us, thus it is the most valuable."
 

Cons

"The solution's stability could be improved."
"There should be more automation security tools in the Control Tower."
"The tool's setup is very technical. Its pricing can be cheaper."
"The sole drawback is its restriction to enable only one Control Tower."
"It could be improved by having a more intuitive graphical interface. It could also include other coding languages like PowerShell and Python, as it would be beneficial for DevOps recommendations."
"There is a sync issue within the organization. It is important that the system syncs automatically instead of requiring me to manually choose sync options."
"AWS should provide more resources, examples, and tutorials."
"The product's affordability depends on the value it brings to specific organizations."
"Hosting platforms are limited so the deployment process needs improvement."
"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 UI, monitoring, and alerting could benefit from further improvements."
"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."
"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."
"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."
"The protocol for clusterization is rough and doesn't work well."
 

Pricing and Cost Advice

"It operates on a pay-as-you-go model, meaning we are charged only for the services we actively use within it."
"The pricing is efficient, not overly expensive but also not very cheap."
"The cost is reasonable, but there are opportunities for improvement in terms of pricing for larger enterprises."
"It is expensive but it is an investment in my opinion."
"On a scale of one to ten, where one is a low price and ten is a high price, I rate the pricing an eight."
"The pay-as-you-go model ensures you're only charged for what you use, which offers great flexibility for different types of companies."
"It is cost-effective and the associated cost is quite minimal."
"I believe it's free of charge or comes at a very low cost. It's an additional feature. Even if there is a fee, it's minimal. AWS seems to assist customers in gaining a comprehensive view of their security setups within AWS. Using Control Tower is highly recommended, especially as your company grows and involves Active Directory, various departments, and different architectural aspects. It becomes more advisable to leverage Control Tower rather than managing these aspects manually, especially for larger organizations."
"VRA is very expensive but OpenNebula is free."
"We use the Community Edition, rather than the Enterprise Edition."
"The solution is open source so 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."
"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."
