DevOps in Space: Lessons from Low Earth Orbit
Remember when you knew all your servers by name and deployed changes with a single SSH command? Now imagine doing that when your link comes in 10-minute windows every few hours, and bandwidth is a precious commodity measured in kbps. Welcome to DevOps in Space.
This is an entry level talk that requires little previous knowledge. The audience will get a general idea of the obstacles and challenges of applying DevOps practices in a New Space company.
The Infrastructure & Software Engineering team at Sateliot works at the intersection of aerospace, telecommunications and software. We build modern distributed systems and then send them to an extremely harsh environment, where normal expectations -low latency, immediate feedback, up-to-date systems- simply don’t apply.
In this talk I’ll give a high-level tour of the challenges that make space and telco different: intermittent and low-bandwidth connectivity, long feedback loops, constrained devices, strong regulation and the cultural gaps between very different fields of engineering. I'll also share the ways we have found within those constraints to apply some of the DevOps processes and tools that have become industry standards.
I started working as a sysadmin when workloads ran on bare metal and Devs were the enemies of Ops. The industry changed and we changed with it, but at the end of the day we're still the ones that receive an alert when things stop working.
