Featured Reviews

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.
Bruna Müller - PeerSpot reviewer
License manager at a financial services firm with 10,001+ employees
Centralized asset data has transformed how we manage licenses and make cost-saving decisions
One problem that we faced using Spot by Flexera is that in certain servers, the data was not being updated correctly, and we had a certain delay. For example, someone was using a computer, and then this user received a new one. In Spot by Flexera, we could see both computers, the old and the new one, but the system was not recognizing that the old one was no longer being used. We had a couple of IT assets that were not being used, and we had this information in our internal servers, but Spot by Flexera was not able to update on time. We had to fix this information manually.
