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.

A highly scalable solution that gives good value for money, but it does not have payment gateways
OpenNebula's templates are weak, and it could do something to make template creation a lot easier to use. The solution has a template for every single VM you create, which is not clever. You should be able to use a template for many different virtual machines. There are no payment gateways in OpenNebula.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It aligns well with the customer's needs and it ultimately fosters a strong customer-company relationship."
"It is incredibly user-friendly and functions seamlessly."
"Control Tower offers many valuable features for managing all account security."
"It offers automated recommendations for security and policies, creating a landing zone and providing a list of policies."
"The most significant benefit of Control Tower is its capability to align with our organization's standards."
"The advantages of AWS Control Tower that stand out for me include centralized management and easy governance control."
"I would rate the solution a 10 out of 10."
"With Control Tower, there are ready-to-use automated templates available, simplifying the implementation of a centralized management solution."
"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."
"With a single click, we could set things up and initiate them."
"OpenNebula freed my customer from doing the maintenance operations of the servers because now that can be done by his clients."
"The solution provides templates for configurations that can easily be exchanged to VMs."
"OpenNebula has given us tremendous knowledge about cloud computing and about Cloud Management platforms, commonly known as CMP."
"OpenNebula is lightweight, stable, and easy to customize."
"It is quite easy to deploy."
"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."
 

Cons

"There is a sync issue within the organization."
"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."
"The reason I do not give it a 10 is that larger enterprises sometimes require more flexibility and customization than the service currently provides."
"The integration with other AWS functions has room for improvement."
"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."
"While using the solution recently, it broke a certain activity. So, AWS Control Tower needs to consider making the solution better."
"The sole drawback is its restriction to enable only one Control Tower."
"The tool's setup is very technical. Its pricing can be cheaper."
"The web interface could be better. It's not very difficult to use, but there's room for enhancement."
"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."
"The UI, monitoring, and alerting could benefit from further improvements."
"Template management also needs improvement in OpenNebula because it's inferior right now."
"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."
"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 front-facing API can be improved to support lots of requests when the platform is huge with lots of virtual resources."
"Hosting platforms are limited so the deployment process needs improvement."
 

Pricing and Cost Advice

"The pay-as-you-go model ensures you're only charged for what you use, which offers great flexibility for different types of companies."
"AWS Control Tower is not really that expensive."
"It operates on a pay-as-you-go model, meaning we are charged only for the services we actively use within it."
"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."
"It is cost-effective and the associated cost is quite minimal."
"The solution is free."
"The pricing structure is closely intertwined with the specifics of your environment and the billing strategy you employ."
"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."
"We use the Community Edition, rather than the Enterprise Edition."
"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."
"OpenNebula gives good value for money."
"VRA is very expensive but OpenNebula is free."
