Sharkrit Impat - PeerSpot reviewer
Head Of Platform Engineering at Ascend Group Co., Ltd.
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

"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."
"AWS Control Tower is a tool specifically designed for multi-account management. It offers the advantage of highly granular management."
"Compliance is the most valuable feature."
"Security is the most valuable feature of Control Tower."
"With Control Tower, there are ready-to-use automated templates available, simplifying the implementation of a centralized management solution."
"The solution's initial setup was easy for me."
"Control Tower offers many valuable features for managing all account security."
"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."
"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."
"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."
"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."
"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."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
"It has enabled us to decrease the optics by around 55 to 60%."
"OpenNebula has very good integration with SAP Storage, is easy to use, has a good UI, and is very scalable."
 

Cons

"It would be beneficial if AWS offered the capability to seamlessly deploy your infrastructure to another region to ensure continuous availability and redundancy."
"The solution's stability could be improved."
"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."
"The tool's setup is very technical. Its pricing can be cheaper."
"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."
"AWS should provide more resources, examples, and tutorials."
"The integration with other AWS functions has room for improvement."
"The initial setup is complex."
"The protocol for clusterization is rough and doesn't work well."
"There are no payment gateways in OpenNebula."
"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."
"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."
"Template management also needs improvement in OpenNebula because it's inferior right now."
"The front-facing API can be improved to support lots of requests when the platform is huge with lots of virtual resources."
"The web interface could be better. It's not very difficult to use, but there's room for enhancement."
 

Pricing and Cost Advice

"The pricing is efficient, not overly expensive but also not very cheap."
"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."
"AWS Control Tower is not really that expensive."
"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."
"It is expensive but it is an investment in my opinion."
"The cost is reasonable, but there are opportunities for improvement in terms of pricing for larger enterprises."
"OpenNebula gives good value for money."
"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."
"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."
