Our TMC usage was limited, and exploring it further was hindered by the lack of an on-premise model. Due to compliance issues with the SaaS model, we couldn't proceed with it as a production-grade product. So, an on-premises model would have been useful for us. VMware rolled out an on-premise model for TMC, allowing for an on-premises implementation, which we learned about six months ago. Also, cost is always a concern. Smaller companies might find the price a bigger issue. Since we were at a large data center, the price might not have been a concern for us. Smaller and medium businesses might hesitate due to the price tag. VMware can be quite expensive.
