Mostly, it is the cost. Microsoft services are costly, which is the only problem we face. So, pricing is an area of improvement. Another downside is that it's very difficult to investigate if something wrong is going on behind the scenes. If we are facing a problem that our application is doing a CPU spike and when we look at the dump of the details, the processes that our application is generating are not consuming more than 40-50% of CPU. But we don’t know where it is going, who's generating it, and who's consuming the CPU. Even Microsoft says they don’t know. They simply said we cannot give you the details. So, a bit of control over such processes or maybe analytics for it is something that needs improvement as well.
