Data platform has transformed analytics and now provides seamless storage and insight on user behavior
Microsoft Azure HorizonDB scales perfectly. It automatically scales whenever there is a load on the application. I have configured the deployment files on my projects, and the database is able to handle automatic scaling by itself, so I do not have to put much attention on that aspect. It scales down automatically as well. I monitored the scaling and scaling out one or two times during the initial stage when I was first including this database in my project. After the first and second times, I checked only the logs for automatic scaling and scaling out. I have not encountered any issue on the scaling side, and it provides consistent performance for both scaling and scaling out.

Real-time analytics have transformed response times and support huge data volumes with compression
I do not have any comment related to the improvement of the solution; for sure, it needs improvement, but for my use cases, it is very sufficient, and I think for the biggest companies, it needs a very powerful infrastructure. The area where improvement is required the most in the product is the UI. The problem with the UI is that it is not complex for understanding, but it needs some training to know what each button does, how it works, and the many variables needed.

"The solution provides a good environment and it's a product we trust."
"Performance is probably the number one feature, because when we use it for OLTP, the response for the end-user is pretty fast, with website response times in micro milliseconds instead of waiting a few seconds for a page to load."
