Mostly yes. We obviously have sales, marketing, etc. as well.
> - How much time do you spend on a week on maintaining your servers?
I don't do devops. There is a team of people that works full-time on IT infrastructure. No idea how time they spend. Gitlab and Zulip servers are updated every couple of weeks. No idea how much time these cost.
> - How do you make sure that your servers are secure? Maybe you are being hacked every night, does your company have the means to check if there has been a security breach?
There is a team of people that work on cybersecurity monitoring. No idea what they do. Normal IT people just make sure that everyone's computer is encrypted, setting up people's credentials, etc.
> Do you follow/apply the security patches for the OS you are using on the server and all the software you are using on the server?
I don't do anything, somebody does this for me.
> Do you have regular offline backups? What would happen if there is a fire in your offices?
We have multiple locations and the backups are replicated across our own locations.
