I'll get it started.

I work in a major print media corp owned by a main TV broadcaster.

Coming into the role, I thought it would be really high tech given their rep, however I came to my desk to find refurbished Apple monitors, a HP desktop and no BYOD-styled environment. Not even mobile phones.

We're broken up into three IT divisions - one is handling our digital publishing and the other handles our internal systems. I'm on the internal team, and we are split into two sub teams; helpdesk and infrastructure. Our infrastructure team is comprised of six administrators who have their own relevant area's; a senior overseer, windows, mac/app, linux, vm/mail, networking.

We span a single row of desks - they're quite large - and we all work relatively independent of each other whilst still utilizing each other skills. That is to say, our Mac/Apps admin might make changes to Linux machines and our linux admin might do some light mail administration on our Exchange, but if there's a major problem/change then the relevant administrator handles it generally.

Everything is pretty relaxed and pretty easy going. Noone's overstressed in infrastructure because everything works which leaves a bit of time for project work and personal stuff. Because infrastructure generally just works (it's been setup well), we just keep it updated, upgraded, and address any issues as they come up. We also handle all the user account creations and other back-end tasks to keep the workload off the helpdesk.

At the moment I don't have any favorite tools for anything. At a previous company, we had a jabber server setup with bots that would handle the bulk of responding to alerts. If we didn't talk to the bot within five minutes, it would send a push alert to our phone and if we didn't respond to that, we would get a phone call and have to say "Acknowledged." which was totally badass when you're out with friends.

Get phone call Put phone to ear, say nothing "Acknowledged." Hang up. Put phone away. Look around the room like nothing happened.

Our monitoring is handled by nagios and it only alerts via email. We don't have an on call roster because the snr sysadmin generally addresses it, or whoever looks after the server will pitch in. We all keep a pretty active eye over our systems so we don't need an on call roster. But if something catastrophic happens, we get phone calls. We monitor servers and switches alike using snmp through nagios. It's hilarious. I'm currently looking at moving us to Zabbix so that I can integrate it with Grafana so that we can have a status board with useful stats. I have also introduced a jenkins server to perform automated tasks which I'm hoping to expand on, created a security procedure for our linux infrastructure and I'm building either a mysql or mariadb cluster depending on what our software vendor will support.

That's pretty much me. My day mainly consists of social media, project work, IRC, reddit, responding to cases as a third level escalation point (normally the issue is a two second fix).
