Last year we signed one of the large Indian outsourcing firms as a customer. The team we worked with ran fleets of AIX boxes for their customers, running their legacy systems. There was a strict requirement not to change the disk image the boxes were generated from. Our most popular integration method is a cross platform golang binary. Unfortunately, we used some key dependencies that would not compile for AIX so we had to abandon that route. We ended up extending our shell scripting integration to use the OpenSSL http client instead of the usual curl. It meant that when sending requests we literally have to prepare and concatenate all the headers, but it works, and we are monitoring all the background jobs on the very old machines, giving the team a way to address operational problems without waiting for reports from their customer.
