Our client was previously using Solar Winds. 

We also use AppDynamics.

We used AppDynamics earlier. Later, we switched to Instana for better pricing.

We use Dynatrace for some of the use cases but not much. Dynatrace is a little bit more expensive, but I got a feeling from teams that Dynatrace is better than Instana with regards to drilling down to the actual issues and other such aspects. The product team and project team might use Dynatrace to have more visibility to the actual problems and do root cause analysis.

We didn't have a previous solution, before Instana, and we didn't provide any APM solution for our customers. Instana came about because we had this managed services division and they had a bundle of things that came along with the managed services fee that they were paying every month. Instana was actually bundled for a lot of people as part of that.

We used an in-house, open-sourced solution. Eric and Grafanna.

We had to switch because we were not successful in developing our own solution.
