The solution is expensive and has room for improvement. I believe the cost is the biggest issue. In Brazil, money is not easy to come by, and paying for this stuff is difficult. Most of my clients are moving to the cloud and purchasing some of the infrastructure there, but it is expensive and they don't always get the economic benefits the cloud can offer. They are creating the infrastructure from the cloud and paying a lot of money for it, and other costs are becoming problematic. Power BI is just one example. The process is the biggest barrier here, and sometimes lack of professional knowledge is also an issue. It is hard to find companies that really know what they are doing. The project I am involved in now is creating a data lake in the cloud for a big client. They hired another company, not mine, to create the project, but when we started the meetings I discovered that the big company they hired doesn't really know what they are doing and is still searching for professionals.
