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.

Streamlines governance and security management but requires effort in managing hidden costs

I believe AWS Control Tower could be improved. I compare it with Huawei Cloud's enterprise project, which is a similar concept but different implementation. In Huawei Cloud, you partition in one single account, but in AWS, you have to separate many accounts. You end up with maybe 20 or 30 accounts if you try to separate. It has limitations; you pay a fixed amount for 15 accounts, but if you exceed that, you have to pay more. It could be useful for implementing a Cloud Center of Excellence (CCOE) for multiple organizations, but for one organization, I would advise against it; it is too much overhead and adds hidden costs. There are limitations on the Landing Zone feature as well. If we implement AWS Control Tower, we need to implement Landing Zone and the security policy, guardrails, and Account Factory; it is not one single product. Using another cloud's enterprise project, you can just create the project and manage it already. It requires some learning curve to get hands-on. For pricing and licensing of AWS Control Tower, it has hidden costs. The Control Tower itself does not cost much, but the child accounts created from AWS Control Tower add costs for checking all configurations, logging, and metrics.

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

"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 helps companies save costs."

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

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

"It provides a central point for account management, access control, and compliance monitoring."

"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."

"The most intriguing feature is the automatic generation of user accounts. Leveraging Active Directory and global company settings, AWS Cloud Tower enables the creation of AWS user accounts based on job descriptions in Active Directory. This establishes a direct correlation between the user's name, job definition, and the corresponding rules applied to each account."

More AWS Control Tower pros

"It has enabled us to decrease the optics by around 55 to 60%."

"OpenNebula has very good integration with SAP Storage."

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

"OpenNebula freed my customer from doing the maintenance operations of the servers because now that can be done by his clients."

"It makes maintenance very easy and stress-free for our teams."

"OpenNebula has very good integration with SAP Storage, is easy to use, has a good UI, and is very scalable."

"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."

More OpenNebula pros

Cons

"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."

"By making APIs and organizational units more centralized, it would be simpler to pinpoint the source of issues in case of a breach and would ultimately benefit everyone involved."

"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."

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

"The tool's setup is very technical. Its pricing can be cheaper."

"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."

More AWS Control Tower cons

"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."

"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 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 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."

More OpenNebula cons

Pricing and Cost Advice

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

"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 pricing is efficient, not overly expensive but also not very cheap."

"AWS Control Tower is not really that expensive."

"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

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

"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."

"VRA is very expensive but OpenNebula is free."

"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."

"OpenNebula gives good value for money."
