Executive SummaryUpdated on Dec 17, 2024

OpenNebula and AWS Control Tower both compete in the cloud management sector. AWS Control Tower seems to have the upper hand due to its comprehensive service offering and integration within the AWS ecosystem.

Features: OpenNebula offers open-source customization and management of private and hybrid clouds with a focus on simplicity. It provides flexible user management, supports various hypervisors, and has a strong community for support. AWS Control Tower is known for its automation in setting up AWS accounts, management guardrails, and comprehensive management of multi-account environments.

Room for Improvement: OpenNebula could enhance its technical documentation and expand its integrations. Its reliance on community support might not suit enterprises needing immediate assistance. AWS Control Tower could improve in simplifying its cost structure and enhancing integration with non-AWS services. Fine-tuning its configuration processes to be more user-intuitive would also be beneficial.

Ease of Deployment and Customer Service: OpenNebula is easy to deploy and manage, suited for organizations seeking simplicity. Its community-based support might require more technical expertise. AWS Control Tower offers streamlined deployment with centralized management and comprehensive AWS customer support, making it suitable for enterprises requiring reliable service.

Pricing and ROI: OpenNebula presents an economical option with a potentially higher ROI for businesses minimizing upfront costs. AWS Control Tower involves higher initial investment due to its extensive features and enterprise support but provides strategic ROI through increased efficiency and reduced operational overhead for AWS-integrated users.

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.

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 incredibly user-friendly and functions seamlessly."

"It offers automated recommendations for security and policies, creating a landing zone and providing a list of policies."

"The solution's initial setup was easy for me."

"I would rate the solution a 10 out of 10."

"It provides centralized solutions for all AWS accounts in one place, customized to meet the organization's specific needs."

"Control Tower offers many valuable features for managing all account security."

"One of the standout advantages is the fine-grained control it offers in terms of permissions and privileges."

"It aligns well with the customer's needs and it ultimately fosters a strong customer-company relationship."

More AWS Control Tower pros

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

"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."

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

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

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

"OpenNebula has very good integration with SAP Storage."

"It is quite easy to deploy."

More OpenNebula pros

Cons

"The integration with other AWS functions has room for improvement."

"The product's affordability depends on the value it brings to specific organizations."

"The solution's stability could be improved."

"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."

"There should be more automation security tools in the Control Tower."

"While using the solution recently, it broke a certain activity. So, AWS Control Tower needs to consider making the solution better."

"The process of closing an AWS account using Control Tower needs improvements to simplify it, especially when managing multiple accounts."

"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."

More AWS Control Tower cons

"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."

"There are no payment gateways in OpenNebula."

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

"The web interface could be better. It's not very difficult to use, but there's room for enhancement."

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

"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."

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

"They should add more features like object storage."

More OpenNebula cons

Pricing and Cost Advice

"It is expensive but it is an investment in my opinion."

"AWS Control Tower is not really that expensive."

"The cost is reasonable, but there are opportunities for improvement in terms of pricing for larger enterprises."

"The pricing structure is closely intertwined with the specifics of your environment and the billing strategy you employ."

"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."

"It operates on a pay-as-you-go model, meaning we are charged only for the services we actively use within it."

"It is cost-effective and the associated cost is quite minimal."

"The product's affordability depends on the value it brings to specific organizations."

More AWS Control Tower pricing and cost advice

"OpenNebula gives good value for money."

"The solution is open source so is free."

"VRA is very expensive but OpenNebula 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."

"We use the Community Edition, rather than the Enterprise Edition."
