Green IT starts with what you can switch off and use for longer

You have a server cabinet in a utility closet, a cloud environment that costs a bit more every year, and a stack of laptops replaced after three years because that is the rule. More and more often, a client or a tender asks what you do for sustainability. Then it turns out nobody knows exactly what runs and what it costs. Green IT does not start with a new label. It starts with counting.

What sustainable IT means in practice

A lot is said about green IT that you cannot check. We stick to three things you can measure: how many servers and virtual machines run, how long your hardware stays in use, and how much data moves for no reason. Each of the three can be put in a number, before and after. That gives you figures you can check yourself, not percentages nobody can verify.

At almost every company we visit, we see the same things. Test servers still running two years after the project. A backup written three times to three places. Workstations replaced because depreciation ended, not because anything is wrong with them. This is not ill will. It is a lack of overview. Creating that overview is the first step, and often the cheapest.

Count first, then switch off

We start with an inventory. Which servers exist, physical and in the cloud, what do they do, and who still uses them? That last question often delivers the most. We measure energy use per machine where we can and estimate it where we cannot, and we set actual use next to it. A server that does something five percent of the time is a candidate to merge with another.

Then we make a list in three columns: switch off, merge, keep. Each item shows what it saves and what the risk is. You decide, we carry it out, and we start with what nobody will miss. That way you stay in control and can stop halfway without leaving anything half done. If you want us to keep watching this on an ongoing basis, we can arrange it through our service desk and help desk, so a forgotten test environment does not run for another two years.

Using hardware longer than depreciation says

Most of the environmental cost of a laptop or server is in making it, not in using it. A device that lasts two years longer is one you do not have to buy, ship, or dispose of. For most office workstations, a five-year-old laptop with a new battery and a faster drive is fine. What is slow is usually the software on it, not the device.

We look at what each group of workstations really needs. A bookkeeper has different requirements than someone who makes drawings. We draw up a replacement schedule based on the condition of the device rather than the purchase date. We also make sure retired hardware gets a second life or is recycled properly instead of disappearing into a drawer. Servers follow a similar logic: a well-run shared environment in a European data center uses its hardware far better than your own cabinet running at thirty percent. Whether that is the right step for you depends on your situation, and we work out such choices in an IT strategy and roadmap.

Less data moving back and forth

Moving data costs power, at both ends and on the way. Many companies sync the same files to three places, email 20 MB attachments back and forth, and run a full backup every night when only a few hundred files have changed. You can fix this without much trouble: incremental backups, one place for files that everyone points to, and integrations that pass on only what changed.

We also design the software we build this way. A report calculated once a night and served from a cache loads your servers less than a page that adds everything up again at every click. That is not a separate green feature. It is careful engineering. At the end of the project, you put the baseline and the follow-up measurement side by side: this many servers fewer, this many devices used longer, this much less data moved. That is a story you can show a client without any green slogans. We begin with a free intake. If it turns out there is little to gain at your company, we tell you right away.
