Chukwudi Uzoma - PeerSpot reviewer
Head Of IT, Infrastructure at a financial services firm with 5,001-10,000 employees
Centralized guardrails have streamlined multi-account governance and accelerated secure onboarding
I rely on the guardrails because they help enforce security and compliance standards without requiring extensive custom development. AWS Control Tower provides tremendous value by simplifying multi-account governance and reducing operational complexity. The reason I do not give it a 10 is that larger enterprises sometimes require more flexibility and customization than the service currently provides. While AWS Control Tower is not primarily an AI-driven service, its governance and security capabilities are among its strongest features, as the combination of guardrails, centralized governance, AWS Organizations integration, and automated compliance monitoring helps AWS organizations establish a secure foundation for AWS adoption. I find AWS Control Tower's governance and compliance output highly reliable, as the service accurately reports guardrail compliance status, account enrollment status, and governance posture, providing trustworthy information for operational and audit purposes. You should start with a clear account strategy, as the design architecture for your organization must be clear. Different organizational units, security requirements, logging strategy, and account lifecycle processes should be clear upfront. AWS Control Tower delivers the most value when implemented as the foundation of a well-planned multi-account architecture. I would also recommend adopting AWS Control Tower early in your cloud journey because it is easier to establish governance from the beginning rather than to try to retrofit governance into a large existing environment later. I rate this solution nine out of ten.
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

"It provides a central point for account management, access control, and compliance monitoring."
"With Control Tower, there are ready-to-use automated templates available, simplifying the implementation of a centralized management solution."
"AWS Control Tower is a tool specifically designed for multi-account management. It offers the advantage of highly granular management."
"AWS Control Tower helps to save a lot of work and manage multiple accounts."
"It offers automated recommendations for security and policies, creating a landing zone and providing a list of policies."
"There are two features in Control Tower which are the most valuable. One is the guardrails because it has preventive and detective guardrails."
"AWS Control Tower provides tremendous value by simplifying multi-account governance and reducing operational complexity."
"It is incredibly user-friendly and functions seamlessly."
"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."
"OpenNebula has given us tremendous knowledge about cloud computing and about Cloud Management platforms, commonly known as CMP."
"It makes maintenance very easy and stress-free for our teams."
"The service feature appeals most to us, thus it is the most valuable."
"OpenNebula has very good integration with SAP Storage, is easy to use, has a good UI, and is very scalable."
"I'll definitely recommend OpenNebula because it's an open-source solution that's effortless to set up, and the total cost of ownership is low."
"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."
"The most valuable feature of OpenNebula is that it scales very well."
 

Cons

"The solution's stability could be improved."
"The initial setup is complex."
"AWS should provide more resources, examples, and tutorials."
"It would be beneficial if AWS offered the capability to seamlessly deploy your infrastructure to another region to ensure continuous availability and redundancy."
"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."
"There aren't any additional features that I feel are missing. However, it's worth noting that Control Tower seems to function as a layer utilizing standard AWS products in the background. Occasionally, the interface may appear less streamlined, with changes in layout based on the underlying products being used. While this doesn't impact functionality, having a more standardized user interface, irrespective of the background products, could enhance the user experience."
"It is essential to clarify that this isn't necessarily a drawback of the service, but having a clear and concise set of predefined guidelines from AWS for moving existing accounts under AWS Control Tower would be highly beneficial as it would simplify the process and make it more user-friendly."
"While using the solution recently, it broke a certain activity. So, AWS Control Tower needs to consider making the solution better."
"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."
"Hosting platforms are limited so the deployment process needs improvement."
"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."
"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."
"The front-facing API can be improved to support lots of requests when the platform is huge with lots of virtual resources."
"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."
"The storage feature that they have is a bit confusing."
"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."
 

Pricing and Cost Advice

"The cost is reasonable, but there are opportunities for improvement in terms of pricing for larger enterprises."
"The product's affordability depends on the value it brings to specific organizations."
"AWS Control Tower is not really that expensive."
"The pricing structure is closely intertwined with the specifics of your environment and the billing strategy you employ."
"The pricing is efficient, not overly expensive but also not very cheap."
"It is expensive but it is an investment in my opinion."
"The solution is free."
"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 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."
"The solution is open source so is free."
"We use the Community Edition, rather than the Enterprise Edition."
"VRA is very expensive but OpenNebula is free."
"OpenNebula gives good value for money."
