South Africa must significantly improve its internet infrastructure to reduce its high costs. I believe South Africa is one of the most expensive countries in the world when it comes to obtaining high-speed internet connections. We need to establish different service level agreements with clients to ensure we have backup lines and redundancy. The crucial question we need to ask ourselves is, how reliable do we want our internet connection to be? In the case of using cloud services, it's essential to have another line as a backup in case the primary one fails. In our situation, having a backup line is definitely necessary, but it also adds to the expenses. For a major bank like ours, relying on a single connection to the cloud is not feasible; we must have a second line in place to ensure uninterrupted service in case of any issues with the primary line.

The cost of Teradata Cloud Data Warehouse has room for improvement.

In terms of improvements, I can only speak from the dashboard perspective. 

The most important thing is that I don't know how far the dashboard integration goes. People, for example, were using the Cloud Data Warehousing product, however, they were actually building their own dashboards, et cetera. That's like double the amount of work. The company should have the ability to integrate with something like Tableau to make everything more standardized.  

With the customer data, we were able to integrate very successfully with Tableau and we were able to use it well from an end-user perspective. We were using the Tableau interface for understanding what our customer buys, et cetera. For example, for the customer financial data aspect of it, the business data, we were able to use Tableau dashboards. It would be better to use back-end data warehousing and also have dashboard reporting and have everything integrated properly. It doesn't need to be Tableau. It can be some other dashboard. However, it needs to be standardized. 

The usability could be a bit better. It could be a bit more user-friendly.

To run our reports I have to upload data from past tables and it is always a problem, so there is a lot of room for improvement there. It just struggles when I have to load data and I would like to see better file processing power.

I have seen instability in automation when working with very large datasets.

Technical support needs improvement.
