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

"AWS Control Tower is a tool specifically designed for multi-account management. It offers the advantage of highly granular management."
"It provides a central point for account management, access control, and compliance monitoring."
"The advantages of AWS Control Tower that stand out for me include centralized management and easy governance control."
"It provides centralized solutions for all AWS accounts in one place, customized to meet the organization's specific needs."
"With Control Tower, there are ready-to-use automated templates available, simplifying the implementation of a centralized management solution."
"AWS Control Tower helps companies save costs."
"AWS Control Tower provides tremendous value by simplifying multi-account governance and reducing operational complexity."
"It aligns well with the customer's needs and it ultimately fosters a strong customer-company relationship."
"It is quite easy to deploy."
"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."
"The most valuable feature of OpenNebula is that it scales very well."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
"It's easy to integrate OpenNebula with our IT systems."
"The live migration feature has been great and is something we use very often."
"OpenNebula freed my customer from doing the maintenance operations of the servers because now that can be done by his clients."
"OpenNebula is lightweight, stable, and easy to customize."
 

Cons

"The product's affordability depends on the value it brings to specific organizations."
"For ROI, I do not see it yet. At that time, it felt excessive because when we create a new project, it should be something small and go to market fast, or an MVP product."
"The process of closing an AWS account using Control Tower needs improvements to simplify it, especially when managing multiple accounts."
"The integration with other AWS functions has room for improvement."
"While using the solution recently, it broke a certain activity. So, AWS Control Tower needs to consider making the solution better."
"AWS Control Tower should improve its fast execution. It also needs more tools for triggering and monitoring AWS services. AWS Control Tower needs more tracking as well."
"The initial setup is complex."
"AWS should provide more resources, examples, and tutorials."
"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."
"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 web interface could be better. It's not very difficult to use, but there's room for enhancement."
"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."
"The storage feature that they have is a bit confusing."
"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."
"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."
"There are no payment gateways in OpenNebula."
 

Pricing and Cost Advice

"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 product's affordability depends on the value it brings to specific organizations."
"The pricing is efficient, not overly expensive but also not very cheap."
"The pay-as-you-go model ensures you're only charged for what you use, which offers great flexibility for different types of companies."
"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."
"The solution is free."
"It operates on a pay-as-you-go model, meaning we are charged only for the services we actively use within it."
"The pricing structure is closely intertwined with the specifics of your environment and the billing strategy you employ."
"The solution is open source so is free."
"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."
"VRA is very expensive but OpenNebula is free."
"OpenNebula gives good value for money."
"We use the Community Edition, rather than the Enterprise Edition."
