What is Level 4 in IT infrastructure?

Okay, so you want me to explain Level 4 in IT infrastructure like I'm just chatting about it, right? Like I'm telling you about it over coffee? I can do that!

Okay, so Level 4 in IT infrastructure... hmm, how to put this? Think of it like this: Level 4 is where the rubber meets the road. It's all about doing things, about actually making the changes and keeping everything running smoothly. It's not just about planning, designing, or even building – it's about the day-to-day.

Basically, at Level 4, you're deep in the weeds of maintenance and changes. Remember that time our whole company's email system went down? (Ugh, don't even get me started!). It was probably some Level 4 engineers scrambling to fix it, right?

The big thing at this level is using all sorts of management tools, like monitoring software, stuff for automation, all designed to keep a close eye on how everything's performing. We're talking about things like CPU usage, network traffic, application response times - the whole nine yards!

And it's not just watching things. Level 4 engineers are usually the ones configuring these tools and scripts to automate a lot of the boring stuff. Imagine having to manually deploy updates to hundreds of servers, one by one? No thanks! Level 4 engineers automate provisioning, testing and deployment. They might create scripts that automatically build a new server or testing environments. That's where all the magic happens, I guess.

So, in a nutshell, Level 4 is all about taking the infrastructure, managing it, and making sure it runs smoothly. What do you think? Does that make sense?
