I use Charon to emulate a SunOS machine for our customers, and I find the emulation tool robust and performant. It lets us keep hosting legacy appliances on modern, redundant infrastructure. Stromasys is capable and reachable—big enough to handle all cases, but with a small-company mentality. Known, trusted people are there and happy to help without Kafkaesque structures. I use the Charon manager and the Azure-hosted licensing server, which works great for our on-prem redundancy setup by dynamically moving license keys. The dynamic licensing has made backup and restore tests much easier than when we had to request new licenses for the dongle. Help is always available, and the documentation is very clear. I appreciate that the company takes care and pride in its software and builds systems that are clearly documented and last. Review collected by and hosted on G2.com.

With the classical license dongle, backup restore tests meant I had to request new licenses, which was quite a hassle and a lengthy process. The Azure licensing server and dynamic licensing have made that much easier to handle, although I miss the option to get a free-of-charge "hey here is a license to spin the machine 15 mins to do some alive and consistency checks", would mean the world in taking a trustworthy backup.
